I'm having troubles with my Users entity.
In my website, users can fill their collection to keep track of their Magic the gathering cards.Every users have one and only one collection. So, I created a table "Collection", mapped in OneToOne between Users and Collection.
This table collection is mapped to a another table named "CollectionContent" in ManyToOne.This table contains only one field, quantity. I created this table because the ManyToMany association doesn't allow additionnals fields.
The table collectionContent is then mapped to Cards in ManyToOne. (to simulate the ManyToMany with an additional field.)
Here comes the problem : I made a mistake while creating the entity at first and created it as ManyToOne between users and Collection. (instead of OneToOne)
And now, I'm trying to call
$userCollectionId = $this->getUser()->getCollection();Which should return the user collection id, and I get an error message :
Return value of App\Entity\Users::getCollection() must implement interface Doctrine\Common\Collections\Collection, instance of App\Entity\Collections returnedI guess there are two possibilities :
- I cant name my entity 'Collection' ? is it a reserved word or something ?
- The methods to get the collection from the user arent good anymore because I changed the ManyToOne into OneToOne and I have to delete something, but I dont know exactly what.
Here's my Users Entity :
