ModelMultiValueField

ModelMultiValueField provides the ability to create sub-forms for foreign models without having to worry about writing the ModelMultiValueField subclasses.

Quick start

1. Add "modelmultivalue" to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
       'modelmultivalue',
   ]
   

2. Add the ModelMultiValueField to a model form

   1. All django version:

      from django import forms
      from modelmultivalue import ModelMultiValueField
      
      class ExampleModelForm(forms.ModelForm):
          class Meta:
              model = Example
              fields = '__all__'
      
          ForeignKeyField = ModelMultiValueField(model=ForeignKey
      

   2. for Django>=1.9:

      from django import forms
      from modelmultivalue import ModelMultiValueField
      
      class ExampleModelForm(forms.ModelForm):
          class Meta:
              model = Example
              fields = '__all__'
              field_classes={
                  'ForeignKeyField': ModelMultiValueField
              }
