xadmin admin inline forms

manipulate inline form field

for existing instances

Jeder inline instance will have new course field queryset

    def instance_form(self, **kwargs):
        instance = super(UserCourseRelationshipInline, self).instance_form(**kwargs)
        for form in instance:
            field = form.fields['course']
            field.queryset = Course.objects.filter(mandantcourse__mandant=self.user.mandant)
        # field = formset.form.declared_fields['course']
        # field.queryset = Course.objects.filter(mandantcourse__mandant=self.user.mandant)
        return instance

pass attributes to inline form

    form = UserCourseInlineAdminForm
    def get_formset(self, **kwargs):
        self.form.user = self.request.user
        return super(UserCourseRelationshipInline, self).get_formset(**kwargs)

in form.py:

class UserCourseInlineAdminForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(UserCourseInlineAdminForm, self).__init__(*args, **kwargs)
        user = self.user

        if hasattr(user, 'mandant'):
            mandant = user.mandant
            self.fields['course'].queryset = Course.objects.filter(mandantcourse__mandant=mandant)

self.formset

the return value of get_formset is a formset_factory (formset generator), it need to be called to make formset with forms:

RecipeFormset = inlineformset_factory(
    Recipe,
    RecipeIngredient,
    extra=len(recipe_ingredients),
    can_delete=False)
formset = RecipeFormset()

for subform, data in zip(formset.forms, recipe_ingredients):
    subform.initial = data

return render_to_response('recipes/form_recipe.html', {
     'form': form,
     'formset': formset,
     })

In xadmin the formset is not populated with get_formset, the forms will be populated with instance_form method
