Magento – Magento 2 : EAV Tutorial Needed

I found a module in Github which has custom EAV Model. I have built custom EAV model successfully by following this module. May be it will help someone.

I've been able to do this within the admin section. You need to have your ResourceModel collection extend from the \Magento\Eav\Model\Entity\Collection\AbstractCollection class. Within your Grid Data provider, load the collection and use addAttributeToSelect('*'):

class Grid extends \Magento\Ui\DataProvider\AbstractDataProvider
{    

public function __construct(
    ....
    \[Namespace]\[Module]\Model\ResourceModel\[Obj]\CollectionFactory $collectionFactory,
    ....
) {
    ....
    $collection = $collectionFactory->create();
    $collection->addAttributeToSelect('*');
    $this->collection = $collection;
    ...
}}

which will load up the attribute values, then you need to specify the columns in the grid in your [Namespace][Module]/view/[loc]/ui_component/[ui_component_grid_name].xml layout:

<listing ...>
...
<columns ...>
    ...
    <column name="[attribute_code]">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                ...
                <item name="label" xsi:type="string" translate="true">[Attribute Label]</item>
                ...
            </item>
        </argument>
    </column>
    ...
</columns>
