Hello, I just delete everything because I tried too much things and needed a fresh start !
I’m also still trying to figure out what is my actual issue because maybe i got it wrong : my wish is to be able to submit a new order to track orders for a shop. An order can have different items (with different quantities) and an item can be in different orders. So I made a many-to-many relationship (with a third table) which works, but the actual problem is how can I have a choice component (or collection?) that display all the available items (from the products table), and how to link every added items to a single order. I’m currently reading this post about many to many relationship.
Hope this is not confusing, thanks for the help !
