Magento2 È necessario creare una griglia con una raccolta di più tabelle utilizzando i componenti dell'interfaccia utente

Iniziato a costruire un modulo personalizzato, ha una funzione per visualizzare la vista GRID per la quale è necessario unire più tabelle nella raccolta e renderle su GRID e filtri.

Ho usato UI Component da magento2 ma non sono in grado di completare le attività di unione di più tabelle nella raccolta e preparare la vista della griglia.

Chiunque può aiutarmi in questo.

Ho creato la griglia di amministrazione che ha l'unione di due tabelle personalizzate. non puoi farlo utilizzando il tipo virtuale in di.xml, quindi devi seguire questi passaggi e aggiornare il tuo

etc / di.xml,

Model / Resource / Modulename / Collection.php aggiungi join in questo file,

Modello / risorse / Modulename / griglia / Collection.php,

Nel tuo etc / di.xml

Spero che aiuti.

Unisciti a 2 tavoli

Nel tuo Vendor\Module\Model\ResourceModel\ModelName\Grid\Collection, aggiungi la funzione _initSelect () come sotto

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']
    );
}

Unisciti a 3 tavoli e altro

Usa thirdTable , 4thTable per unire più tabelle come di seguito:

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
}
