down votefavorite <http://stackoverflow.com/questions/39708397/modelform-with-reverse-foriegnkey#> I am trying to create a ModelForm for movie Model from which it must be possible to select a number of theatre for each movie.Since theatre is reverse foreignkey i think ModelForm doesn't automatically saves theatre values to the database.i tried to override the save method and ended up with the error. Exception Type: ValueError Exception Value: save() prohibited to prevent data loss due to unsaved related object 'movie'. Anyone please help me to solve this and thanks in advance. class movieAdminForm(forms.ModelForm): theatre = forms.ModelMultipleChoiceField(queryset=theatre.objects.all(), widget=forms.widgets.CheckboxSelectMultiple()) class Meta: model = movie fields = ('image', 'image2', 'title', 'language', 'director', 'cast', 'y_tube_url', 'synopsis', 'like', 'music', 'cast', 'duration', 'genre', 'date', 'rating', 'writer','theatre') def save(self,*args,**kwargs): super(movieAdminForm,self).save(*args,**kwargs) self.instance.theatre.clear() for i in self.cleaned_data['theatre']: self.instance.theatre.add(i) -- You received this message because you are subscribed to the Google Groups "Django users" group.
