Django草垛與Elasticsearch後端

我想在Django 1.8.2上使用Haystack與Elasticsearch 1.6作爲後端，但無法獲得乾草堆教程爲我工作。Django草垛與Elasticsearch後端

在運行rebuild_index我碰到下面的錯誤和堆棧跟蹤

您是否創建了模板「search/indexes/regeste/regeste_text.txt」？ –

是的，路徑設置爲./templates/（即在與各個應用程序相同的級別），我已經設置了'TEMPLATE_DIRS =（ os.path.join（BASE_DIR，'模板'），）在settings.py ...所以它應該被發現，對吧？ – danba

考慮發佈您的應用程序目錄樹和相關設置。你可能做得很好，或者你沒有做到。沒有看到就很難說。 –

DIRS在TEMPLATES字典優先於TEMPLATE_DIRS, which is deprecated as of Django 1.8。

設置DIRS至[os.path.join(BASE_DIR, 'templates')]。

更好

的是，你應該把在一個應用程序的模板目錄此模板（使用在模型定義的應用程序），因爲這可能是它應該活。

按照您的建議將模板移動到應用的模板目錄中。謝謝。 – danba

只需創建模板目錄裏面的應用程序，然後移動搜索目錄到這個模板目錄。現在它會工作。
