Extbase looking for wrong table - typo3

Question

I'm using TYPO3 7.4.0 and I'm learning to build extensions in extbase & fluid.
I have a vendor prefix in my table names. I create three tables for my extensions. When I go in the backend and add entities in the list view on the resource folder I created, it works without any problems. When I go to the Frontend to view the index action of my entity it looks for a table without the vendor prefix in it's name. Does anyone know what that means? I create the tables in the "ext_tables.sql". I have no table mapping defined. I don't know where to change which tables extbase is looking for.

Answer 1

By default Extbase looks for table using schema tx_extkey_domain_model_modelname, so for Animal model in zoo ext it will be tx_zoo_domain_model_animal. (extkey without underscore if any!)
If you used other schema (like vendor name within table name) you need to use mapping. I.e. create file ext_typoscript_setup.txt in main folder of your ext and use this:
config.tx_extbase{
persistence{
classes{
Vendor\Zoo\Domain\Model\Animal {
mapping {
tableName = tx_your_own_name
}
}
}
}
}
BTW: it's best idea to keep the original naming schema. Other thing is that creating extensions manually can be tricky - at least for beginners, install Extension Builder ext to fast kickstart new extensions just with click-click way.
