Question

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

Answer 1

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。

Answer 2

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。

Django Haystack与Elasticsearch后端
