instance = form.save(commit=False)
instance.updated_by = self.request.user
instance.save()
instance.save_m2m()
I'm getting below error. Django version 1.11.6
AttributeError: 'ModelName' object has no attribute 'save_m2m'
But in documentation
https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/
every time you save a form using commit=False, Django adds a save_m2m()
method to your ModelForm subclass. After you’ve manually saved the
instance produced by the form, you can invoke save_m2m() to save the many-
to-many form data.

Comment:
You need to use `form.save_m2m()` rather than `instance.save_m2m()`.
