我想限制django" list_filter"在Django admin中显示。
根据我的模型,我只希望它显示类别中的类别(在过滤器中)并包含层整数" 1"。
这可能吗?
class Category(models.Model):
category_name = models.CharField(max_length=100, blank=False)
tier = models.IntegerField(blank=false)
def __str__(self):
return self.category_name
class Product(models.Model):
name = models.CharField ("Name", max_length=400)
link = models.URLField("Link", max_length=900)
store = models.ForeignKey(Store)
category = models.ManyToManyField(Category, blank=True)
在管理员中,我有:
list_filter = ('category')
我相信我需要将这些内容纳入其中?
category=Category.objects.get(tier__iexact='1')
答案 0 :(得分:2)
这样的事情应该有效:
from django.contrib import admin
from django.utils.encoding import smart_text
from django.utils.translation import ugettext_lazy as _
class CategoryListFilter(admin.SimpleListFilter):
title = _('Category')
parameter_name = 'category'
def lookups(self, request, model_admin):
categories = Category.objects.filter(tier=1)
for obj in categories:
yield (str(obj.pk), smart_text(obj))
def queryset(self, request, queryset):
if self.value():
return queryset.filter(category__id=self.value())
class ProductAdmin(admin.ModelAdmin):
list_filter = (CategoryListFilter,)
