I am using a mixin class on some of my models that provides a few extra fields:
> class Mixin(models.Model): > code = models.CharField(max_length=8, blank=True, unique=True) > hint = models.CharField(max_length=8, unique=True, null=True, > blank=True) > > class Meta: > abstract = True > This class is mixed in with arbitrary other models in my application: class Foo(models.Model, Mixin): > has_bar = models.BooleanField(default=True) > The fields from the mixin class always show up "on top" of the other fields when a ModelForm is created. I am aware of using the Meta class attribute 'fields' to specify ordering of form fields, but that also requires explicitly duplicating the names of all fields in my form, which violates DRY. Additionally, explicit duplication of field names is inconvenient and redundant, and defeats the purpose of the mixin class. Is there a good way to dynamically reorder these fields on the fly? Preferably, the code should be contained within the Mixin class. In my situation, the mixin fields would be better if placed after all the other fields on a model, but in other situations a mixin might want a different order. Surely there is a way to change this without requiring the Meta class of every ModelForm that I might derive from any model using Mixin to know specifics about the fields of each individual model? -- Visit me @ http://killarny.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
