You could just steal the field from the manipulator containing the
references.
Wouldn't this work;
class Model1(models.Model):
content = models.CharField(maxlength=100)
blah = models.CharField(maxlength=100)
ref_model2 = models.ForeignKey(Model2)
class UsageExample(CustomAddManipulator):
def __init__(self):
self.fields = [
forms.LargeTextField(field_name='content',
is_required=True),
forms.LargeTextField(field_name='content2',
is_required=True),
forms.LargeTextField(field_name='blah', is_required=True),
]
self.get_manipulators()
for field in self.manipulators[0].fields:
if field.field_name == 'ref_model2':
self.fields.append(field)
self.models = (('Model1',('content', 'blah', 'ref_model2')),
('Model2', ('content2', 'blah')))
Is that sufficient? I was thinking that a nice addition to
CustomAddManipulator would be a default __init__(), that pulled in
the manipulators for all the models and grabbed all the fields in
those models. Then you could just define;
class Usage(CustomAddManipulator):
models = (('Model1',('content', 'blah', 'ref_model2')),
('Model2', ('content2', 'blah')))
And get all the necessary fields.
I just realized the issue that you were actually trying to bring up,
which is how to define a relationship between the instance of Model1
and Model2 being created. Since I'm just leveraging the
AddManipulators tied to models I can't see a way of doing that and
preserving the feel of a model-tied manipulator.
