Symfony is only able to make plural-to-one conversion (elizabeth.g. regarding the tags possessions to your addTag() method) getting English conditions. Code written in another words won’t become questioned.
To save the latest tags having Philosophy, you really need to envision two a whole lot more something. Earliest, if you don’t iterate overall of the the new Mark stuff and you will telephone call $entityManager->persist($tag) for each, you get an error regarding Philosophy:
To fix that it, you might «cascade» the brand new persevere process immediately regarding Activity target to your relevant tags. To polish hearts mobil sitesi accomplish this, are the cascade option to the ManyToMany metadata:

A second prospective thing works with the brand new Having Front side and Inverse Edge of Dple, in the event the «owning» area of the matchmaking was «Task», upcoming time and energy will be able to work since tags was safely extra to the Activity. But not, if your having front is found on «Tag», then you’ll have to do a little bit more work to ensure that the best region of the relationships try changed.
The key is to try to guarantee that the fresh single «Task» is determined for each «Tag». One good way to do that is to try to add some more reasoning to help you addTag() , to create of the means kind of as by the_resource is set so you’re able to not true :

Whenever deleting stuff like this, you might have to do some little more strive to make sure the dating amongst the Task as well as the removed Mark is actually safely got rid of.
Usually in this case you should have a plenty of-to-you to definitely relationships while the deleted labels will recede and you may persevere precisely (adding the newest tags plus performs easily).
But if you keeps a-one-to-of many dating or a quite a few-to-of a lot experience of a great mappedBy to the Task entity (definition Task ‘s the «inverse» side), you will need to manage a great deal more work for the newest eliminated labels to help you persevere truthfully.
In this case, you could potentially customize the operator to eradicate the connection towards got rid of mark. This assumes that you have specific revise() action which is handling the «update» of your Task:
As you can see, adding and you will removing the weather truthfully would be problematic. If you do not have a many-to-of numerous dating in which Activity ‘s the «owning» front side, you’ll need to would a lot more strive to ensure that this new relationships are securely updated (whether you’re including the fresh new tags or deleting existing tags) on every Level object itself.
