python - django-advanced-filters 'grp_tags' 不是有效的标签库

Question

我在 python2.7 上使用 django-advanced-filters 和 django 1.8 django-高级过滤器==1.0.1 django 大括号==1.4.0 django-easy-select2==1.2.5

它工作正常，但是当我尝试修改过滤器时，它失败了: 模型.py:

from django.db import models
from django.utils import timezone
from django.utils.translation import ugettext_lazy as _

class SalesRep(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    email = models.EmailField(_('email address'), blank=True)
    duty = models.CharField(max_length=30, blank=True)
    def __unicode__(self):
        return '{} {}'.format(self.first_name, self.last_name)


class Client(models.Model):
    VALID_LANGUAGES = (
        ('en', 'English'),
        ('sp', 'Spanish'),
        ('it', 'Italian'),
    )
    USERNAME_FIELD = 'email'

    language = models.CharField(max_length=8, choices=VALID_LANGUAGES, default='en')
    email = models.EmailField(_('email address'), blank=True)
    first_name = models.CharField(_('first name'), max_length=30, blank=True)
    last_name = models.CharField(_('last name'), max_length=30, blank=True)
    is_active = models.BooleanField(
        _('active'), default=True,
        help_text=_('Designates whether this user should be treated as '
                    'active. Unselect this instead of deleting accounts.'))
    assigned_to = models.ForeignKey(SalesRep)
    date_joined = models.DateTimeField(_('date joined'), default=timezone.now)
    def __unicode__(self):
        return '{} {}'.format(self.first_name, self.last_name)

admin.py:

from django.contrib import admin
from advanced_filters.admin import AdminAdvancedFiltersMixin
from .models import *

@admin.register(Client)
class ClientAdmin(AdminAdvancedFiltersMixin, admin.ModelAdmin):
    list_filter = ('first_name', 'last_name', 'language', 'is_active')
    advanced_filter_fields = ('language', 'first_name',
                              ('assigned_to__email', 'Sales Rep.'))

admin.site.register(SalesRep)

如何解决这个问题？

Answer 1

django-advanced-filters作者在这里。您所描述的问题已在即将发布的版本 1.0.2 中修复(将于本周末发布)。 出现这个问题的原因是我们以前依赖django-grappelli但已转向更通用的方法。

如果你实在等不及发布，你可以安装最新的开发分支 directly from the github repo像这样:

pip install https://github.com/modlinltd/django-advanced-filters/archive/develop.zip
