django-specifications 0.2.0

Usage

1. Add 'specifications' to INSTALLED_APPS.

2. Create a specification = ForeignKey('specifications.Specification') on the model you want to use specifications with. The foreign key can be nullable or required, as you wish.

3. Create the place where the specification field data is actually stored:

   from specifications.models import SpecificationValueFieldBase
   
   class MyObjectField(SpecificationValueFieldBase):
       parent = models.ForeignKey(MyObject, related_name='fields')
   
       class Meta:
           ordering = ['field__group__ordering', 'ordering']

4. Inherit from FormWithSpecification when creating your ModelForm:

   from specifications.forms import FormWithSpecification
   
   class MyObjectForm(FormWithSpecification):
       class Meta:
           model = MyObject

5. There is no fifth step.

The fields are available after saving a specification. The specification can be changed, but you risk losing data if you do this.
