Magento 2 getTable behavior

Question

TL;DR: Is there any way in Magento 2 to make the method getTable from a resource collection model to return the same table name for 2 different parameters?

Detailed Explanation
I will start with an example from Magento 1.
Let's say I have a table called module_entiti1_entity2.
I needed to declare this table in my config.xml like this

<module_resource>
    <class>....</class>
    <entities>
         <entity1_entity2>
             <table>module_entiti1_entity2</table>
         </entity1_entity2>
    </entities>
</module_resource>

Then I can get the table name from a resource collection model for example like this:

$collection->getTable('module/entity1_entity2');

But if I want I can use multiple aliases for the same table.
If my config.xml section becomes

<module_resource>
    <class>....</class>
    <entities>
         <entity1_entity2>
             <table>module_entiti1_entity2</table>
         </entity1_entity2>
         <entity2_entity1>
             <table>module_entiti1_entity2</table>
         </entity2_entity1>
    </entities>
</module_resource>

I can retrieve my table in 2 ways:

$collection->getTable('module/entity1_entity2');
$collection->getTable('module/entity2_entity1');

In Magento 2 there is no more table declaration like above.
I can get my table name like this $collection->getTable('module_entity1_entity2').
Is there a way to tell magento that for the parameter module_entity2_entity1 to return the same table name as for the parameter module_entity1_entity2?

Answer 1

What you're looking for is setMappedTableName. Call this inside your resource model:

$this->_resources->setMappedTableName('module_entity1_entity1', 'module_entity1_entity2');

You can put this inside a function then call that before calling the getTable method.

Basically, it says that whenever I ask for module_entity1_entity1, give me the module_entity1_entity2 table.
