We'll I created a new function called r_col. That returns a value to
my sandp field from within the Style Class. However, I'm not sure how
to pass it the current value of the collection field from within the
Style Class. Below are my model files:
class Choice(models.Model):
choice = models.ForeignKey(Collection, edit_inline=models.TABULAR,
num_in_admin=5)
size = models.ForeignKey(Size, core=True)
price = models.ForeignKey(Price, core=True)
def __str__(self,):
return str((self.size, self.price))
def r_col(ob):
assert False, ob # This just returns a ForeignKey object. Not the
value of collection which is what I need
return 2
class Style(models.Model):
name = models.CharField(maxlength=200, core=True)
color = models.CharField(maxlength=100)
color_cat = models.ForeignKey(ColorCategory)
image = models.ImageField(upload_to='site_media/')
theslug = models.SlugField(prepopulate_from=('name',))
manufacturer = models.ForeignKey(Manufacturer)
collection = models.ForeignKey(Collection,
edit_inline=models.TABULAR, num_in_admin=6)
sandp = models.ManyToManyField(Choice, limit_choices_to =
{'choice__id': r_col(collection)})
def __str__(self,):
return self.name
class Collection(models.Model):
name = models.CharField(maxlength=200)
collectionslug = models.SlugField(prepopulate_from=["name"])
description = models.TextField(maxlength=1000)
manufacturer = models.ForeignKey(Manufacturer)
def __str__(self,):
return self.name
class Admin:
list_display = ('name', 'manufacturer')
list_filter = ('manufacturer',)
/////////////////
Thanks for any help.
