我试图在Django 1.8.2上使用Haystack，将Elasticsearch 1.6作为后端但不能让干草堆教程为我工作。
在运行rebuild_index时，我收到以下错误和堆栈跟踪
./manage.py rebuild_index

Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.

我很欣赏任何有关问题所在的提示。

答案 0 :(得分：2)
DIRS词典中的 TEMPLATES优先于TEMPLATE_DIRS, which is deprecated as of Django 1.8。
将DIRS设为[os.path.join(BASE_DIR, 'templates')]。
更好的是，您应该将此模板放在应用程序的模板目录中（使用定义模型的应用程序），因为它可能存在于应用的位置。
答案 1 :(得分：0)
只需在应用内创建模板目录，然后将搜索目录移至此模板目录。现在它会起作用。
