How to add to manytomany field in Django

Posted on By Luke K

To add items to a many-to-many field in Django, you need to use the add() method. Here’s how:

First, retrieve the model instance you want to add items to. For example:

book = Book.objects.get(id=1)

Next, retrieve the items you want to add to the many-to-many field:

authors = Author.objects.filter(id__in=[1, 2, 3])

Finally, add the items to the many-to-many field using the add() method:


book.authors.add(*authors)

Note that the * operator is used to unpack the QuerySet into individual arguments, so that each item in the QuerySet is added as a separate item to the many-to-many field.

Once you’ve added items to a many-to-many field, you can also use other methods like remove() and clear() to manipulate the items in the field.
