Hi Brant, thanks for your comment. Effectively the model was wrong and
your fix has been very useful.
This is the working version:
from django.core import meta
class Ingredient(meta.Model):
fields = (
meta.CharField('name', 'Name', maxlength=128),
meta.TextField('description', 'Description', blank=True),
)
admin = meta.Admin()
def __repr__(self):
return self.name
class Recipe(meta.Model):
fields = (
meta.CharField('name', 'Name', maxlength= 128, unique=True),
meta.TextField('description', 'Description')
)
admin = meta.Admin()
def __repr__(self):
return self.name
class Intermediary(meta.Model):
fields = (
meta.ForeignKey(Ingredient, blank=True, core=True),
meta.PositiveIntegerField('quantity', 'Quantity', blank=True),
meta.ForeignKey(Recipe, edit_inline=True)
)
I also have changed the order of classes definition. In the previous
model it was Ingredient, Intermediary, Recipe: adding inside
Intermediary a reference to Recipes, it gave: NameError: name 'Recipe'
is not defined
So the model now defines classes in this order: Ingredient, Recipes,
Intermediary and all works fine.
My question is.. if order matters, is there the possibility, expecially
in complex models, to reach a "deadlock" condition?
Thanks,
paolo
