Magento2 Besoin de construire une grille avec plusieurs collections de tables à l'aide de composants d'interface utilisateur

Commencé sur la construction de modules personnalisés, il a la fonctionnalité d'afficher la vue GRID pour laquelle il faut joindre plusieurs tables dans la collection et les rendre sur GRID et les filtres.

J'ai utilisé le composant d'interface utilisateur de magento2 mais je ne suis pas en mesure de terminer les tâches de jonction des plusieurs tables dans la collection et de préparer la vue de la grille.

Quelqu'un peut m'aider à ce sujet.

J'ai créé une grille d'administration qui a joint deux tables personnalisées. vous ne pouvez pas le faire en utilisant le type virtuel dans di.xml, vous devez donc suivre ces étapes et mettre à jour votre

etc / di.xml,

Model / Resource / Modulename / Collection.php ajouter une jointure dans ce fichier,

Model / Resource / Modulename / Grid / Collection.php,

DANS votre etc / di.xml

J'espère que cela pourra aider.

Rejoignez 2 tables

Dans votre Vendor\Module\Model\ResourceModel\ModelName\Grid\Collection, ajoutez la fonction _initSelect () comme ci-dessous

protected function _initSelect()
{
    parent::_initSelect();

    $this->getSelect()->joinLeft(
        ['secondTable' => $this->getTable('admin_user')], //2nd table name by which you want to join
        'main_table.user_id= secondTable.user_id', // common column which available in both table 
        '*' // '*' define that you want all column of 2nd table. if you want some particular column then you can define as ['column1','column2']
    );
}

Rejoignez 3 tables et plus

Utilisez thirdTable , quartTable pour joindre plus de tables comme ci-dessous:

protected function _initSelect()
{
    parent::_initSelect();

    $this->getSelect()->joinLeft(
        ['secondTable' => $this->getTable('admin_user')],
        'main_table.user_id = secondTable.user_id',
        ['username']
    )->joinLeft(
        ['thirdTable' => $this->getTable('catalog_product_entity')],
        'main_table.product_id = thirdTable.entity_id',
        ['sku']
    );//use fourthTable, fifthTable to join more tables
}
