I have three tables (Manufacturer, Collection, Style). I have 10
manufacturers. Each manufacturer contains approx. 20 collection.
Each collection contains approx. 20 Styles. I was wondering if it's
possible when I'm adding styles I can select the manufacturer then my
collection (foreign key) field when drilled-down on shows only the
collections from the manufacturer I selected in the field above. I'm
thinking that this might require some javascript.
Below are some of my tables
class Manufacturer(models.Model):
name = models.CharField(maxlength=200)
manufacturerslug = models.SlugField(prepopulate_from=["name"])
description = models.TextField(maxlength=1000)
def __str__(self,):
return self.name
class Admin:
pass
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',)
class Style(models.Model):
name = models.CharField(maxlength=200)
theslug = models.SlugField(prepopulate_from=('name',))
collection = models.ForeignKey(Collection)
class Admin:
search_fields = ['name']
list_filter = ('collection',)
list_display = ('name', 'theslug','collection', 'rmanu')
def __str__(self,):
return self.name
def rmanu(self):
return self.collection.manufacturer
Thanks for any help
