• I have a profile model which contains education and created a many to
  many relation i.e many profiles can have many educations.


• I have a template called Profile settings which contains multiple forms like Education CreateView, Education UpdateView and Education ListView. I'm using bootstrap modals to display these forms. Hence the they share same template.


• Problem is whenever I save education form, it saves form in database
  and it shows in the education multiselect field of that profile in
  django admin but unselected, it does not create a m2m link between
  profile and education.


• I overrided the save() method to create the link as suggested by the community but I'm not able to get the current profile. Getting this error after saving. ('EducationForm' object has no attribute 'request')

Models

class Profile(models.Model):
 phone = models.CharField(max_length=11, null=True, blank=True)

You'd need to pass the current user or request to the Form instance, so you could override get_form_kwargs in EducationView:

def get_form_kwargs(self):
 kwargs = super(EducationView, self).get_form_kwargs()
 kwargs['request'] = self.request
 return kwargs

and then initialize the EducationForm like this:

def __init__(self, request, *args, **kwargs):
 super(EducationForm, self).__init__(*args, **kwargs)
 self.request = request

As an aside, shouldn't the related_name field in Profile be profiles?
