Django add many to many relationship from _meta.get_field

Question

So I have the following

b = Brand.objects.create(**model_fields_and_values)
b.save()

and then I try to associate that entry with

b._meta.get_field("myfield").add(value3)

and I get the error 'ManyToManyField' object has no attribute 'add'

How can I create an association using a string and not the field ???

I dont want to use b.myfield.add(value3)

Answer 1

getattr允许您使用属性名称获取属性：

getattr(b, 'myfield').add(value3)
