[TYPO3-mvc] 1 to many relation

[Federico Bernardin]

Hi Key, I have done like you said.
In Flow I can relate two entities (with 1:n) and when I fetch one entitity I can access list of related entities of the other object and viceversa. How can I use this feature in extbase? I see extbase checks the value of tca, is it a limit?

Regards
federico
