Usage

The Vue Data Table component works by pulling its configuration through an initialization request. After loading its configuration through that first request, it makes another request for pulling in its data, based on its configuration.

If UI changes occur that require the reload of the data (such as when searching, sorting, etc) or the loading of additional data, such as when changing to the next page of results, another request for data is made.

This means that the configuration is not re-read as long as the component is not re-drawn.

Note: In order to make the above requests, named routes are required.

Steps:

  1. Create the JSON table configuration template.

Example: exampleTable.json

  1. Create the table controller which defines the query and gives the path to the JSON template
class UserTableController extends Controller
{
    use Datatable, Excel;

    protected $tableClass = UserTable::class;
}

Example: TableController.php

  1. Create the table builder class, which must extend the abstract Table class, set the $templatePath variable and implement the query method
class UserTable extends Table
{
    protected $templatePath = __DIR__.'/../Templates/users.json';

    public function query()
    {
        return User::select(\DB::raw(
                'users.id as "dtRowId", owners.name as owner, users.first_name, users.last_name, users.phone,
                users.email, roles.name as role, users.is_active'
            ))->join('owners', 'users.owner_id', '=', 'owners.id')
            ->join('roles', 'users.role_id', '=', 'roles.id');
    }
}

Example: ExampleTable

  1. Declare the route(s) in your routes file, to make available your controller's methods
Route::get('init', 'TableController@init')->name('init');
Route::get('data', 'TableController@data')->name('data');
Route::get('exportExcel', 'TableController@exportExcel')->name('exportExcel');

Example: web.php

  1. Import and place place the VueTable VueJS component in your page/component and pass it the necessary properties. Within the Enso ecosystem, you may use instead the EnsoTable component which requires fewer parameters as it uses Enso specific defaults.

Example: index.blade.php

validations

is a string, values may be always/local, default local. When parsing the template, the given options are validated because we want to avoid misconfiguration leading to unexpected results. It makes sense to run the validator just during development, however, if you want to also run it in production, you may configure that here.

labels

is an array of options for the header names of the implicit columns. Note that these labels are also translated if a translation function is given to the VueJS component, through the i18n parameter. Options:

  • crtNo is the current line number, default #
  • actions, is the last table column that contains the row's buttons, default Actions

lengthMenu

is an array of numbers, default [10, 15, 20, 25, 30] representing the pagination options for the table. For each table's JSON template, the lengthMenu parameter is also available, and, if given, it will have higher priority over the global configuration. This allows for some tables to have a different pagination than the default.

buttons

is an array of button configurations, with 2 types:

  • global, these buttons are the buttons that are rendered above the search input, global for the whole table, which do not depend on the data of a particular row. Defaults:
    • create, button for creating a new resource
    • excel, button for exporting the contents of the table. Note: The export process takes into account your current sorting and filtering.
    • action, button for applying an action to all the (filtered) table rows
  • row, these are the buttons rendered in the action column, and defaults include: show, edit, destroy, download

style

is an array of style configurations, with 2 sections:

  • default, array of classes, default is ['hover', 'center'], that are applied by default for all tables. Note that you should set just one alignment specific class in the default.
  • mapping, array of configurations for the styles. While designed for/with Bulma, you may specify here custom classes in order to personalize your tables
  • highlight, string, default is has-background-info, class which is applied for highlighted rows

export

is an array of configuration options for exporting the contents of a file. Note: The export process takes into account your current sorting and filtering. Also keep in mind that the export uses Jobs and Queues hence the need for a couple of the following options. Available options:

  • path, string, folder where the temporary export file is saved, default exports. This folder is expected to reside in storage/app
  • timeout, number, the value for Laravel jobs timeout. You may want to tweak this depending on the time the export takes due to the server hardware or other factors
  • notifications, array of notification options, default ['broadcast', 'database']. Note that email notifications are always used for sending the download link for the export file

queues

Here you may configure the queues used for the export process: Available options:

  • exports, string, the name of the queue used for the actual export. Keep in mind this queue need to exist for your project configuration
  • notifications, string, the name of the queue used for the real-time progress UI notifications

dateFormat

is a string, with the date format for date columns, which will be used when displaying date values

debounce

is a number, the interval value used for the server-side requests (in milliseconds)

responsive

is a boolean that determines if the table is responsive (automatically hides columns when its width it wider than available)

method

is a either "GET" or "POST". If you're working with larger tables sometimes the URI can get too long and you may run in a 414 Exception. This option allows to configure the request method for fetching data in a local table. If specified in the table template, the local value will have higher priority over the global configuration.

fullInfoRecordLimit

is a numeric limit, representing the top result set limit when the computation of the filtered & totals functionality becomes disabled by default and is made available on-demand.

dataRouteSuffix

string, is the data route suffix used for all tables. Similar to fullInfoRecordLimit, you may override the global configuration by specifying this same parameter in the 'local' table template.

comparisonOperator

string, is the default comparison operator used when searching, you may override the global configuration by specifying this same parameter in the 'local' table template. Valid values are LIKE, ILIKE.

Options:

  • routePrefix, required, string, the common route segment, used for reading the data
  • dataRouteSuffix, optional, string, the ending route segment, used for reading the data | default is tableData
  • name, optional, string, the title used for the table export. If not given, no title is used
  • crtNo, optional, boolean, flag for showing the current line number
  • cache, optional, boolean, flag for activating the cache for the table total count (more information in the Caching Support section)
  • flatten, optional, boolean, flag for flattening the response, allowing columns like "user.person.name" in the template
  • auth, optional, boolean, flag for removing auth when using in enso context
  • debounce, optional, number, the time in milliseconds that is used for the debounce when reloading data for the table, for example when typing in the search box or changing filters, default 100
  • lengthMenu, optional, array, list of options for the table pagination. If missing, the default values in the global configuration are used. If given, the template values have higher precedence over the global configuration
  • method, optional, string, either "GET" or "POST". If missing, the default value in the global configuration is used.
  • appends - optional, array, list of appended attributes that need to be added to the query results. Note that the appended attributes are available from the main query model. Also note, that in order to load the appended attributes through the model's relationships, the raw table query should also include the foreign key id (this is a Laravel requirement).
  • selectable, optional, boolean. If enabled, row selection is enabled, which then stores the selected items (the dtRowId attributes) in the selected attribute.
  • comparisonOperator, optional, string, the operator used for the table columns searching
  • buttons, optional, array, list of buttons that need to be rendered. See below for more in-depth information
  • columns, required, array, list of column configurations. See below for more in-depth information

Buttons

There are several type of buttons, depending on how you classify them.

By configuration:

  • simple, declared as a string, representing one of the string buttons from the config. Example: "show", "create", "edit", "destroy", "download", "exportExcel"
  • complex, declared as an object, with several attributes.

By position:

  • row, buttons that are rendered on each row, in the actions column. Example: "show", "edit", "destroy", "download", or custom buttons with the type:"row" configuration.
  • global, buttons that are rendered above the search input, at the top of the table VueJS component. Example: "create", "exportExcel", or custom buttons with the type:"global" configuration.

By action:

  • router, buttons that trigger an action/navigation through the VueJS router, "action": "router"
  • href, buttons that trigger an action/navigation through a plain HTML link
  • export, buttons that trigger an export
  • ajax, buttons that trigger an ajax request.

The most common configuration options for buttons are, as follows:

  • type: required, string, available options are row / global
  • icon: required, string, expects Font Awesome icon classes (ensure classes are available in the page)
  • class: required, string, expects CSS styling classes
  • routeSuffix: optional, string, if given, gets appended to the routePrefix template param
  • event: optional, string, the name of an event that is emitted on click, which allows for custom in-page handling, outside of the table
  • postEvent: optional, string, the name of the event that is emitted after the completion of the ajax request (only applies to ajax type of buttons)
  • action: optional, string, available options are router / href / export / ajax.

Depending on the chosen options, other parameters could be required:

  • fullRoute: optional, string, if given, is used independently from the routePrefix param
  • label: optional, string, for both global buttons and row buttons
  • tooltip: optional, string, should be provided only for row buttons
  • confirmation: optional, boolean, flag for showing a confirmation modal before processing the action, such as deletion
  • message: optional, string, used in conjunction with confirmation, when you want to customize the modal's message
  • method: optional, string, should be given if you have action set as ajax, available options are: "GET" / "PUT" / "PATCH" / "POST" / "DELETE"
  • params: optional, object, used if action = router, object is added to route params object

Columns

The columns configuration attribute is required, and expects an array of configuration objects. Each configuration object may have the following attributes:

  • label, required, string, the column name used in the table header. This will be translated if a translation function is available.
  • data, required, string, the table + column wherefrom data gets pulled, in the query. For example 'users.email'
  • name, required, string, the alias for that column's data, given in the select query. Alternatively you may also use here nested properties - see the notes below for more info
  • enum, optional, string, the class name of the enumeration used to transform/map the values of that column/attribute. For example, you may use this mechanism to show labels instead of integer values, for an attribute that holds the type for a model/table.
  • dateFormat, string, with the date format for date columns, overrides the default from config
  • tooltip, optional, the text used for this column header's tooltip
  • class, optional, will be applied on the table's <td>
  • align, optional, a value in ["left", "center", "right"], will be applied to the column including header and footer. It has higher priority than the global template align attribute
  • meta, optional, array of string tags/options, allowing further transformations:
    • searchable, optional, marks this column as searchable. If not searchable, a column is not used when using the table search functionality
    • sortable, optional, marks this column as sortable. If not sortable, the controls to sort are not available for sorting
    • sort:ASC / sort:DESC, optional, specifies the default sort for this column. Note that after the initial load, the user will have the option to override the sorting as needed
    • nullLast, optional, makes the sorting on this column sort all null values last
    • translatable, optional, marks this column's values as translatable The i18n parameter translation function should be given to the VueJS table component in order for this to work - inside of Enso, this is done automatically
    • boolean, optional, marks this column as boolean, which means it will be rendered as such
    • slot, optional, renders a scoped slot named after the specified column, exposing as props column (object), row (array) and loading (boolean)
    • rogue, optional, marks this column as a rogue column. This marks the column as hidden for display, while still being available and used for searching
    • total, optional, if flagged, calculates a total for this column
    • customTotal, optional, renders a scoped slot named ${columnName}_custom_total exposing as props total (object) and column (object)
    • date, optional, marks the data of the column as dates,
    • icon, optional, if given, it renders a Font Awesome 5 icon as contents, using the 'column.icon' as the icon's class
    • clickable, optional, flags the column as clickable, which means it makes it - you guessed it - clickable. When clicked, it emits the clicked event, with the column & row as event payload
    • notExportable, optional, flags the column to be skipped on exports
  • money, optional, object, is the configuration object used for formatting numbers as money values. Since this is achieved via the accounting.js library, you should take a look at its documentation here

The name attribute and nested properties

Since the 1.5.7 package version, it has become possible to use nested models properties for the name attribute. For example, for the users table template, you could update the entity section to:

    {
        "label": "Group",
        "name": "group.name",
        "data": "",
        "meta": []
    }

and in the table builder class update the select query to:

    return User::select(\DB::raw(
        'users.id, users.id as "dtRowId", avatars.id as avatarId, group_id,
        people.name, people.appellative, people.phone, users.email, roles.name as role,
        users.is_active, users.created_at'
    ))->join('people', 'users.person_id', '=', 'people.id')
    //->join('user_groups', 'users.group_id', '=', 'user_groups.id')
    ->with('group')
    ->join('roles', 'users.role_id', '=', 'roles.id')
    ->leftJoin('avatars', 'users.id', '=', 'avatars.user_id');

You may notice a few things here:

  • the name attribute value is the nested model name + property
  • a data value is no longer required
  • the meta attribute value's list can no longer contain "searchable", "sortable". If you do give these options, the template validator will let you know that you should remove them
  • in order for the relationship to work, make sure the select includes any required foreign keys i.e. if you'd leave out owner_id, the value of the returned owner attribute would be null
  • also, don't forget to load the relationship, using the query builder's with method
  • this feature makes sense for 1-1 model relationships, not so much for 1-n relationships
  • note that all the nested model's properties will be present in the returned data and depending you your situation, this might be inefficient
  • if you require searching and sorting, build the required query with joins and specify the value for the data attribute

Notes on exporting

The new exporting feature used in this package allows for the export of practically unlimited number or rows (or, to be more accurate, the number of rows is limited by the xlsx format).

In order to achieve this, Laravel queues and jobs are used, so it is mandatory to:

  • have the Laravel queueing functionality properly setup and working
  • make sure the queues specified in the enso.datatable.exports config also exist in your Laravel queue config
  • ensure you're using values fitting your project and hardware for:
    • enso.datatable.exports.timeout - this is the job timeout, so you should have an interval longer than your longest job
    • queues.connections.yourConnection.retry_after - this is the interval used by Laravel to mark a job as failed, if it's not completed by then. This interval should also be longer than your longest running job.

The query

In your TableBuilder implementation, the query must look like this:

public function query()
{
    return UserGroup::select(\DB::raw('id as "dtRowId", id, name, description, is_active, created_at'));
}

Keep in mind that at this stage, we're returning a QueryBuilder not a collection of results.

If you need custom logic based on the request you have a request() getter available in the TableBuilder.

Actions

While you may have action buttons on each table row, sometimes you may wish to have custom actions, for the entire result set of the table.

It is important to note that the action will be applied for ALL the FILTERED results, even the ones that might not be visible on the current page of the table (if there is more than one page).

Also, keep in mind that if the selectable option is active in table template, the selection is decoupled from the actions, so, same as before, the action is applied to all the filtered table results.

In-depth example - global custom action

In order to achieve this functionality, we've included an example below, where we add a new button for the owners table:

  1. Update your table JSON template, to include the button(s) for the action(s)
...
"buttons": [
        "excel", "create", "edit", "destroy",
        {
            "type": "global",
            "icon": "check",
            "class": null,
            "routeSuffix": "myAction",
            "event": "custom-action",
            "postEvent": "custom-action-done",
            "action": "ajax",
            "method": "PATCH",
            "label": "My Action"
        }
]
...    

Customize the attributes as required, keeping in mind:

  • the method should match the action performed and needs to be the same as when defining the route
  • the suffix is what you'll need to use when defining the route (more on that below)

Note that, if needed, you may define several buttons in a similar fashion.

  1. Add a new Action implementation class, where you actually process the results.
class UserGroupMyAction extends Action
{

    public function process()
    {
        \Log::info($this->data());
    }
}

This needs to extend the abstract LaravelEnso\VueDatatable\app\Classes\Action class, and implement the process method. The process method will be called for each available row of data.

Depending on your requirements, you may do the processing here or even generate jobs that will do the processing asynchronously.

  1. Add a new controller for the action
class UserGroupMyActionController extends Controller
{
    use Datatable, Action;

    protected $tableClass = UserGroupTable::class;
    protected $actionClass = UserGroupMyAction::class;
}

The controller manages the VueJS component's action request. You require:

  • the Datatable and Action trait
  • the $tableClass variable, for the query
  • the $actionClass variable, for your particular action implementation (from step 2)

Note that you may also reuse your TableController if you prefer and have only one 'action' for a given table.

Additional Advanced Details

The Action trait defines an action method that is a bit of a wrapper, and looks like this:

public function action(Request $request)
    {
        public function action(Request $request)
            {
                (new $this->actionClass(
                    $this->tableClass, $request->all()
                ))->run();
            }
    }

If for any reason you want to handle more than one action through the same controller, you may declare multiple actionClasses and create multiple action methods in conjunction with the proper routes.

1.Add the new route

Route::patch('myAction', 'UserGroupMyActionController@action')
                            ->name('myAction');

Remember to place the route nested correctly, considering the possible uri and route name prefixes, as well as the controller namespace.

In this example, the url called for the UserGroups table will be 'administration/userGroups/myAction' and the name of the route will be 'administration.userGroups.myAction'.

  1. Create the new permission Navigate in the app to system/permissions and add the new administration.userGroups.myAction permission.

  2. That's it.

The default action button

If you take a look the package config file, you'll notice that there already is a global action button defined. If you want to use it, you make skip the definition of a button at #1 step above, instead just declare "action" and continue with the other steps, taking into account the changed suffix (the route and permissions need to be altered).

Defining reusable action buttons

Similarly to the default action button, you may define other 'global' action buttons in the datable configuration, that can then be used as needed in any table templates in your project.

In-depth example - per row custom action

A common scenario is when you want to define a per row custom action, on top of the default ones.

Most of the time, you'll want to perform the custom action for the model that's represented on the row so you'll need to be able to identify the model. For that, you can use the dtRowId attribute.

If you're displaying data gathered from multiple tables, make sure that the identifiers you require are present in the select and in the template. If you don't want to display them to the user, you may use rogue columns.

In this example, we'll assume dtRowId is sufficient.

  1. Build the query in the table builder

    public function query()
    {
        return MyModel::select(\DB::raw('
            my_models.id as "dtRowId",
            my_models.name
        '));
    }
    
  2. Declare the custom action button in the template:

"buttons": [
    "excel",
    "create",
    "edit",
    "destroy",
    "show",
    {
        "type": "row",
        "icon": "exclamation-triangle",
        "class": "is-row-button",
        "event": "details",
        "confirmation": false
    }
],

We've named the event details.

Remember that the icon you set for the custom action button must be available (imported) in the page (component) where you're displaying the datatable.

  1. In the page, catch the event on the datatable Vue component:
<vue-table class="box has-background-light is-paddingless raises-on-hover is-rounded"
    :path="path"
    id="myModelTableId"
    @details="handleDetails"/>
  1. Process the event as desired:
    ...
    methods: {
        handleDetails(event) {
            const id = event.dtRowId;
            //your custom logic
        },
    },
    ...
};

The event payload is the entire table row, so you have access to the id (dtRowId) and any other attributes you've added.

Configurable huge result set management

When you have huge result sets, the table component will take longer to respond to the user input. In order to improve the user experience, when we have more results than the limit set in the configuration (in the fullInfoRecordLimit key), the back-end builder no longer computes the number of filtered records and totals for that table.

However, a blue information icon becomes available in the list of table buttons, that allows the user to request this computed information.

Since this is an extreme case with tables this big and is a seldom situation, the configuration for the limit is global.

Caching support

We've had cases in production where we need to work with over 2 million results and every performance bit we can get is welcome.

When the table displays data, if we want to show pagination, we need to execute the main query twice: once to retrieve the current chunk of data, and then once more to count the results.

By caching the number of results we can skip counting the results and save time for each request. The more records you work with, the bigger the gain the difference.

In order to activate this feature, in the table template, add the cache option and set it to true.

...
"method": "POST",
"crtNo": true,
"cache": true,
...

On the next request, if the total count information is not in the cache, it will be computed and also cached for 1 hour.

You should always use this only in combination with the TableCache trait on the table's main model. The trait will handle the cache invalidation when a model is created or deleted. To do so add the trait and set protected $cachedTable property value to the id of your vue-table component.
