Haystack与Django 1.4不兼容？

Question

我刚刚将我的django升级到了1.4.我在干草堆应用程序遇到麻烦.此外,我试图更新haystack到最后的稳定版本,但我仍然有问题.有没有人有这些错误？我该如何解决？

我收到以下错误.

当我访问任何页面时:

cannot import name MAX_SHOW_ALL_ALLOWED haystack\admin.py in <module>, line 2

和

# python manage.py rebuild_index
django.core.exceptions.ImproperlyConfigured: Error importing template source loader
django.template.loaders.app_directories.load_template_source:
    "'module' object has no attri bute 'load_template_source'"

谢谢

Answer 1

haystack/admin.py文件中存在问题.尝试执行以下操作:

1. 删除导入 MAX_SHOW_ALL_ALLOWED

2. 课前SearchChangeList添加方法:

   def list_max_show_all(changelist):
       """
       Returns the maximum amount of results a changelist can have for the
       "Show all" link to be displayed in a manner compatible with both Django
       1.4 and 1.3. See Django ticket #15997 for details.
       """
       try:
           # This import is available in Django 1.3 and below
           from django.contrib.admin.views.main import MAX_SHOW_ALL_ALLOWED
           return MAX_SHOW_ALL_ALLOWED
       except ImportError:
           return changelist.list_max_show_all
   

3. 在SearchChangeList.get_results()变化can_show_all到

   can_show_all = result_count <= list_max_show_all(self)
