Re: Can a ManyToManyField only shows certain records in an admin using edit_inline?
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.

Re: Can a ManyToManyField only shows certain records in an admin using edit_inline?
Ok..does anybody know what's wrong with this attempt at trying to get
the 'limit-choices_to' to work?
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)
class Style(models.Model):
name = models.CharField(maxlength=200, core=True)
color = models.CharField(maxlength=100)
image = models.ImageField(upload_to='site_media/')
theslug = models.SlugField(prepopulate_from=('name',))
manufacturer = models.ForeignKey(Manufacturer)
sandp = models.ManyToManyField(Choice, limit_choices_to =
{'choice': get_choices(self)})
collection = models.ForeignKey(Collection,
edit_inline=models.TABULAR, num_in_admin=6)
def get_choices(self, style_name):
g = Choice.objects.filter(pk=style_name.collection)
return g

Re: Can a ManyToManyField only shows certain records in an admin using edit_inline?
We'll I kinda got it to work. I added the following
(limit_choice_to):
sandp = models.ManyToManyField(Choice, limit_choices_to = {'choice':
2})
///
That works fine. However, I obviously want to take out the '2'. I
tried the following but it does not seem to work:
sandp = models.ManyToManyField(Choice, limit_choices_to = {'choice':
collection.id})
I guess I need to know how do I get the id for the current collection
that I'm adding the style to?
Thanks

Try using the limit_choices_to argument to ManyToManyField: http://www.djangoproject.com/documentation/model-api/#many-to-many-relationships Hope this helps, Will. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Can a ManyToManyField only shows certain records in an admin using edit_inline?
> Is there anyway that I can have the 'sandp' Field only > show choices that are tied to that collection? This is the purpose of making ForeignKeys I guess. You may try: mycollection = Collection.objects.all()[0] related_choices = Choice.objects.filter(choice=mycollection) I think that /choice/ is not a good name for the ForeignKey if it is a collection, isn't it ? When you create a foreignkey, the related model (collection), get a *magic* attribute which is choice_set in this case: related_choices = mycollection.choice_set.all() I advise you to add *related_name* argument for your for foreignkey, it's easier to read and remember of the magic relations, eg: class Choice(models.Model): collection = models.ForeignKey(Collection, related_name=choices) it's really the same, but then you can do: related_choices = mycollection.choices.all() > sandp = models.ManyToManyField(Choice=collection.id)? This is bullshit, isn't it ? moreover, you never have to use directly the id... or personnaly I never do. You can do Choice=mychoice > Thanks :) related docs: http://www.djangoproject.com/documentation/model-api/#many-to-one-relationships http://www.djangoproject.com/documentation/db-api/#related-objects ebg13, EGSZ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
