Hi all!
I have 3 classes in model.py
class Category(models.Model):
category = models.CharField(max_length=130)
def __unicode__(self):
return self.category
class Subcategory(models.Model):
category = models.ForeignKey('Category')
subcategory = models.CharField(max_length=130)
def __unicode__(self):
return self.subcategory
class Product(models.Model):
subcategory = models.ForeignKey('Subcategory')
product = models.CharField(max_length=20)
def __unicode__(self):
return self.product
I'd like to add in product admin form a dropdown of category.
I've tried this in admin.py
from django.contrib import admin
from products.models import Category, Subcategory, Product
from django.contrib.admin.options import ModelAdmin
from django.http import HttpResponse
class AdminProduct(ModelAdmin):
#Original Idea. It works
#fieldsets= ( (None, {'fields': ('subcategory', 'product')}), )
#Custom. Trying to access category dropdown. It doesnt work
fieldsets= ( (None, {'fields': (Subcategory.category,
'subcategory', 'product')}), )
admin.site.register(Product, AdminProduct)
Error reported:
Error while importing URLconf 'myproject.urls': category must be
accessed via instance
How can I do to have a select of catagory in the admin form of
product?
Sorry for my stupid question, I'm beginner :(
