Into the Philosophy, you have got a couple of sides of your own relationships: the new owning side plus the inverse front
Symfony can only just result in the plural-to-one conversion process (age.grams. on the labels assets for the addTag() method) to possess English terminology. Password printed in any vocabulary won’t become expected.
To save the tags which have Philosophy, you will want to think several a great deal more some thing. First, unless you iterate total of your own new Level objects and call $entityManager->persist($tag) on every, you will get an error out of Philosophy:
To resolve it, you could potentially “cascade” the newest persevere procedure instantly on the Task object to virtually any associated labels. To achieve this, add the cascade option to their ManyToMany metadata:
- Annotations
- YAML
- XML
The next possible thing deals with the fresh new Having Front and you may Inverse Side of Dple, if your “owning” area of the matchmaking try “Task”, after that perseverance will be able to work due to the fact labels is actually properly extra toward Task. not, if your having front side is on “Tag”, then you will must do a little bit more work to make sure the right area of the matchmaking was changed.
The secret would be to make certain this new single “Task” is decided on each “Tag”. One way to do that should be to atart exercising . extra logic so you can addTag() , which is sometimes called from the means particular as because of the_source is determined to false :

Enabling Labels to get Removed
The next phase is to let the fresh removal out-of a certain goods on the range. The answer is much like allowing labels to-be extra.
Template Modifications
New allow_delete choice implies that in the event the an item of a portfolio is not delivered towards the distribution, the new related info is taken from new collection towards the server. To ensure which to be effective during the an enthusiastic HTML means, you need to take away the DOM feature into the range item so you can go off, just before submission the proper execution.
Whenever a tag means is completely removed from the DOM and you will submitted, new removed Tag target will not be within the collection passed so you’re able to setTags() . Based your effort level, this may or is almost certainly not sufficient to in fact remove the dating within eliminated Level and you may Task object.
Whenever deleting things like this, you may need to do a bit of little more try to ensure that the dating between your Task plus the removed Mark is safely removed.
Usually in this instance you should have a countless-to-one to relationships plus the erased tags will go away and you will persevere correctly (incorporating the brand new labels and additionally works with ease).
But if you enjoys a one-to-many relationship or a lots of-to-of numerous relationship with a beneficial mappedBy toward Task organization (meaning Task ‘s the “inverse” side), you will need to create far more work with the new got rid of labels in order to persist correctly.
In cases like this, you could potentially modify the control to get rid of the connection for the got rid of tag. Which takes on you have particular change() step that is handling the “update” of your own Activity:
As you can plainly see, including and removing the weather correctly shall be difficult. If you do not has a plenty of-to-of several relationship where Task is the “owning” top, you’ll want to perform a lot more strive to make certain that brand new matchmaking was securely upgraded (whether you are including the fresh labels or deleting existing tags) on each Level target itself.
The Symfony society has generated specific JavaScript packages that give the new possibilities wanted to include, edit and erase parts of the brand new collection. Check out the /symfony-range plan to have modern internet explorer plus the symfony-collection package considering jQuery for the remainder of browsers.
You have got to perform both addTag() and removeTag() measures, if not the proper execution have a tendency to nonetheless use setTag() even when by_source is untrue . You will then see much more about the fresh new removeTag() approach later in this post.
