I would love to write up a howto for UPDATING a manyTOMany field, but I
cannot figure out how it is done. I would love to get the concept here:
I have a db model called "Projects" with a ManyToMany field called
"Team"
when updating the Project I want to also update the Team(s)
In the manipulator, I validate the data, etc:
manipulator = Project.ChangeManipulator(project_id)
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
manipulator.save(new_data)
Does the manipulator call the "save" function in my Project model?
if so why do I get "TypeError at /projectlist/edit/2/ save() takes
exactly 2 arguments (1 given)"
In the Manipulator base class the save funciton's signature is: def
save(self, new_data):
In my Model.save():
super(Project,self).save()
and I try to save the related Objects:
self.team = data['team'] #ManyToMany
self.enduser = data['enduser'] #ForeignKey
self.rigorlevel = data['rigorlevel'] #ForeignKey
I wish the docs were more clear... What am I doing wrong?
Best,
d
