django-advanced-filters'grp_tags'不是一個有效的標籤庫

Question

我在python2.7上使用django-advanced-filters和django 1.8.0 django-advanced-filters == 1.0.1 django-braces == 1.4.0 Django的易於選擇2 == 1.2.5

它工作正常，但是當我嘗試修改過濾器，它失敗： models.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)

如何解決這一問題？

Answer 1

django-advanced-filters作者在這裏。你正在描述的問題已在即將發佈的1.0.2版本中解決（將於本週末發佈）。 這個問題的原因是我們過去依賴於django-grappelli，但已經轉移到更通用的方法。

如果你絕對不能等待釋放，可以安裝最新的開發分支directly from the github repo像這樣：

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