Magento 2: How to Create Admin Grid

Overview

To show how to add custom ui grid to the admin panel, we will use MageDirect_Faq module from this article.

Create ACL

Create Access Control List Rules (ACL) file to control access to our Faq grid:

 <!-- app/code/[VendorName]/[ModuleName]/etc/acl.xml -->    <?xml version="1.0"?>  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Acl/etc/acl.xsd">     <acl>         <resources>             <resource id="Magento_Backend::admin">                 <resource id="Magento_Backend::content">                     <resource id="Magento_Backend::content_elements">                         <resource id="MageDirect_Faq::faq" title="Faqs" translate="title" sortOrder="100"/>                     </resource>                 </resource>             </resource>         </resources>     </acl>  </config>

<?xml version="1.0"?>

<acl>

</resource>

</resources>

</acl>

</config>

Add new menu item

Add new menu item by editing etc/adminhtml/menu.xml inside the module. In this case, we will add an item under Content > Elements:

 <!-- app/code/[VendorName]/[ModuleName]/etc/adminhtml/menu.xml -->    <?xml version="1.0"?>  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">     <menu>         <add id="MageDirect_Faq::faqs" title="Faqs" translate="title" module="MageDirect_Faq" sortOrder="100"               parent="Magento_Backend::content_elements" action="faq/faq" resource="MageDirect_Faq::faq"/>     </menu>  </config>

<?xml version="1.0"?>

<menu>

<add id="MageDirect_Faq::faqs" title="Faqs" translate="title" module="MageDirect_Faq" sortOrder="100"

parent="Magento_Backend::content_elements" action="faq/faq" resource="MageDirect_Faq::faq"/>

</menu>

</config>

“Add” directive has next attributes:

the id attribute is the unique name in format VendorName_ModuleName::menu_name;
the title attribute will be visible in the menu bar;
the module attribute specifies the module which this menu item belongs to;
the action attribute contains the url of the page on which our admin grid will be shown;
the resource attribute is used to define the ACL rule which the admin user must have in order to access this menu item;
the parent attribute defines parent menu item;
the sortOrder attribute defines menu item position inside menu bar.

Add routes.xml

To etc/adminhtml folder add routes.xml file with the next content:

 <!-- app/code/[VendorName]/[ModuleName]/etc/adminhtml/routes.xml -->    <?xml version="1.0"?>  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">     <router id="admin">         <route id="faq" frontName="faq">             <module name="MageDirect_Faq" />         </route>     </router>  </config>

<?xml version="1.0"?>

</route>

</router>

</config>

Create admin controller class

 <?php    // app/code/[VendorName]/[ModuleName]/Controller/Adminhtml/Faq/Index.php    namespace Magedirect\Faq\Controller\Adminhtml\Faq;    use Magento\Backend\App\Action\Context;  use Magento\Framework\View\Result\PageFactory;    class Index extends \Magento\Backend\App\Action  {        /**       * Authorization level of a basic admin session       *       * @see _isAllowed()       */      const ADMIN_RESOURCE = 'MageDirect_Faq::faq';        /**       * @var PageFactory        */      protected $resultPageFactory;        /**       * @param Context $context       * @param PageFactory $resultPageFactory       */      public function __construct(Context $context, PageFactory $resultPageFactory)      {          $this->resultPageFactory = $resultPageFactory;          parent::__construct($context);      }        /**       * @return \Magento\Framework\Controller\ResultInterface       */      public function execute()      {          /** @var \Magento\Backend\Model\View\Result\Page $resultPage */          $resultPage = $this->resultPageFactory->create();          $resultPage->setActiveMenu('MageDirect_Faq::faqs')                  ->getConfig()->getTitle()->prepend(__('Faqs'));          return $resultPage;      }    }

<?php

// app/code/[VendorName]/[ModuleName]/Controller/Adminhtml/Faq/Index.php

namespace Magedirect\Faq\Controller\Adminhtml\Faq;

use Magento\Backend\App\Action\Context;

use Magento\Framework\View\Result\PageFactory;

class Index extends \Magento\Backend\App\Action

{

/**

* Authorization level of a basic admin session

* @see _isAllowed()

const ADMIN_RESOURCE = 'MageDirect_Faq::faq';

/**

* @var PageFactory

protected $resultPageFactory;

/**

* @param Context $context

* @param PageFactory $resultPageFactory

public function __construct(Context $context, PageFactory $resultPageFactory)

{

$this->resultPageFactory = $resultPageFactory;

parent::__construct($context);

}

/**

* @return \Magento\Framework\Controller\ResultInterface

public function execute()

{

/** @var \Magento\Backend\Model\View\Result\Page $resultPage */

$resultPage = $this->resultPageFactory->create();

$resultPage->setActiveMenu('MageDirect_Faq::faqs')

->getConfig()->getTitle()->prepend(__('Faqs'));

return $resultPage;

}

Clean cache

Clean cache and we will see the new empty page in the admin panel:

  <span style="font-weight: 400;">php bin/magento cache:clean</span>

1	<span style="font-weight: 400;">php bin/magento cache:clean</span>

Now we can add a simple grid to this page by using UI Component. Let’s do it.

Сreate layout file

 <!-- app/code/[VendorName]/[ModuleName]/view/adminhtml/layout/faq_faq_index.xml -->    <?xml version="1.0"?>  <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">      <body>          <referenceContainer name="content">              <uiComponent name="faq_listing"/>          </referenceContainer>      </body>  </page>

<?xml version="1.0"?>

<body>

</referenceContainer>

</body>

</page>

Our UI Component will have a name faq_listing.

Create faq_listing.xml

Create faq_listing.xml inside ui_component folder:

 <!-- app/code/[VendorName]/[ModuleName]/view/adminhtml/ui_component/faq_listing.xml -->    <?xml version="1.0" encoding="UTF-8"?>  <listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">      <argument name="data" xsi:type="array">          <item name="js_config" xsi:type="array">              <item name="provider" xsi:type="string">faq_listing.faq_listing_data_source</item>          </item>      </argument>      <settings>          <spinner>faq_listing_columns</spinner>          <deps>              <dep>faq_listing.faq_listing_data_source</dep>          </deps>      </settings>      <dataSource name="faq_listing_data_source" component="Magento_Ui/js/grid/provider">          <settings>              <storageConfig>                  <param name="indexField" xsi:type="string">faq_id</param>              </storageConfig>              <updateUrl path="mui/index/render"/>          </settings>          <aclResource>MageDirect_Faq::faq</aclResource>          <dataProvider class="Magento\Framework\View\Element\UiComponent\DataProvider\DataProvider" name="faq_listing_data_source">              <settings>                  <requestFieldName>id</requestFieldName>                  <primaryFieldName>faq_id</primaryFieldName>              </settings>          </dataProvider>      </dataSource>      <columns name="faq_listing_columns">          <column name="faq_id">              <settings>                  <filter>textRange</filter>                  <label translate="true">ID</label>                  <sorting>asc</sorting>              </settings>          </column>          <column name="title">              <settings>                  <filter>text</filter>                  <editor>                      <validation>                          <rule name="required-entry" xsi:type="boolean">true</rule>                      </validation>                      <editorType>text</editorType>                  </editor>                  <label translate="true">Title</label>              </settings>          </column>          <column name="content">              <settings>                  <filter>text</filter>                  <editor>                      <validation>                          <rule name="required-entry" xsi:type="boolean">true</rule>                      </validation>                      <editorType>text</editorType>                  </editor>                  <label translate="true">Content</label>              </settings>          </column>          <column name="created_at" class="Magento\Ui\Component\Listing\Columns\Date" component="Magento_Ui/js/grid/columns/date">              <settings>                  <filter>dateRange</filter>                  <dataType>date</dataType>                  <label translate="true">Created</label>              </settings>          </column>          <column name="updated_at" class="Magento\Ui\Component\Listing\Columns\Date" component="Magento_Ui/js/grid/columns/date">              <settings>                  <filter>dateRange</filter>                  <dataType>date</dataType>                  <label translate="true">Modified</label>              </settings>          </column>      </columns>  </listing>

Add the class

It is important to add the class that is responsible for preparing data for the grid (faq_listing_data_source):

 <!-- app/code/[VendorName]/[ModuleName]/etc/di.xml →    <?xml version="1.0"?>  <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">      <type name="Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory">          <arguments>              <argument name="collections" xsi:type="array">                  <item name="faq_listing_data_source" xsi:type="string">MageDirect\Faq\Model\ResourceModel\Faq\Grid\Collection</item>              </argument>          </arguments>      </type>      <type name="MageDirect\Faq\Model\ResourceModel\Faq\Grid\Collection">          <arguments>              <argument name="mainTable" xsi:type="string">magedirect_faq</argument>              <argument name="eventPrefix" xsi:type="string">magedirect_faq_grid_collection</argument>              <argument name="eventObject" xsi:type="string">magedirect_faq_grid_collection</argument>              <argument name="resourceModel" xsi:type="string">\MageDirect\Faq\Model\ResourceModel\Faq</argument>          </arguments>      </type>  </config>    <?php    //app/code/[VendorName]/[ModuleName]/Model/ResourceModel/Faq/Grid/Collection.php    namespace MageDirect\Faq\Model\ResourceModel\Faq\Grid;    use Magento\Framework\Api\Search\SearchResultInterface;  use Magento\Framework\Search\AggregationInterface;  use MageDirect\Faq\Model\ResourceModel\Faq\Collection as FaqCollection;    class Collection extends FaqCollection implements SearchResultInterface  {      /**       * @var AggregationInterface       */      protected $aggregations;        /**       * @param \Magento\Framework\Data\Collection\EntityFactoryInterface $entityFactory       * @param \Psr\Log\LoggerInterface $logger       * @param \Magento\Framework\Data\Collection\Db\FetchStrategyInterface $fetchStrategy       * @param \Magento\Framework\Event\ManagerInterface $eventManager       * @param string $mainTable       * @param string $eventPrefix       * @param string $eventObject       * @param string $resourceModel       * @param string $model       * @param \Magento\Framework\DB\Adapter\AdapterInterface|string|null $connection       * @param \Magento\Framework\Model\ResourceModel\Db\AbstractDb $resource       *       * @SuppressWarnings(PHPMD.ExcessiveParameterList)       */      public function __construct(          \Magento\Framework\Data\Collection\EntityFactoryInterface $entityFactory,          \Psr\Log\LoggerInterface $logger,          \Magento\Framework\Data\Collection\Db\FetchStrategyInterface $fetchStrategy,          \Magento\Framework\Event\ManagerInterface $eventManager,          $mainTable,          $eventPrefix,          $eventObject,          $resourceModel,          $model = \Magento\Framework\View\Element\UiComponent\DataProvider\Document::class,          $connection = null,          \Magento\Framework\Model\ResourceModel\Db\AbstractDb $resource = null      ) {          parent::__construct(              $entityFactory,              $logger,              $fetchStrategy,              $eventManager,              $connection,              $resource          );          $this->_eventPrefix = $eventPrefix;          $this->_eventObject = $eventObject;          $this->_init($model, $resourceModel);          $this->setMainTable($mainTable);      }        /**       * @return AggregationInterface       */      public function getAggregations()      {          return $this->aggregations;      }        /**       * @param AggregationInterface $aggregations       * @return $this       */      public function setAggregations($aggregations)      {          $this->aggregations = $aggregations;      }        /**       * Get search criteria.       *       * @return \Magento\Framework\Api\SearchCriteriaInterface|null       */      public function getSearchCriteria()      {          return null;      }        /**       * Set search criteria.       *       * @param \Magento\Framework\Api\SearchCriteriaInterface $searchCriteria       * @return $this       * @SuppressWarnings(PHPMD.UnusedFormalParameter)       */      public function setSearchCriteria(\Magento\Framework\Api\SearchCriteriaInterface $searchCriteria = null)      {          return $this;      }        /**       * Get total count.       *       * @return int       */      public function getTotalCount()      {          return $this->getSize();      }        /**       * Set total count.       *       * @param int $totalCount       * @return $this       * @SuppressWarnings(PHPMD.UnusedFormalParameter)       */      public function setTotalCount($totalCount)      {          return $this;      }        /**       * Set items list.       *       * @param \Magento\Framework\Api\ExtensibleDataInterface[] $items       * @return $this       * @SuppressWarnings(PHPMD.UnusedFormalParameter)       */      public function setItems(array $items = null)      {          return $this;      }  }
