Django ModelForm instance with custom queryset for a specific field
try something like this in the view
form = BikeForm()form.fields["made_at"].queryset = Factory.objects.filter(user__factory)modify the Factory queryset so that it identifies the factory which the user works at.
You question might be a dupe of this.
S. Lott's answer there is the ticket to solve your problem.He answered:
ForeignKey is represented by django.forms.ModelChoiceField, which is a ChoiceField whose choices are a model QuerySet. See the reference for ModelChoiceField.
So, provide a QuerySet to the field's queryset attribute. Depends on how your form is built. If you build an explicit form, you'll have fields named directly.
form.rate.queryset = Rate.objects.filter(company_id=the_company.id)If you take the default ModelForm object,form.fields["rate"].queryset = ...This is done explicitly in the view. No hacking around.
Nowaday, you should use:
form.base_fields['alumno_item'].queryset = AlumnoItem.objects.prefetch_related( 'alumno', 'alumno__estudiante', 'alumno__estudiante__profile', 'item' )
