Haystack和Solr-模式解析失敗

Question

我正在嘗試rebuild_index，但在構建模式（manage.py build_solr_schema）後，我將輸出複製並粘貼到schema.xml文件中。重新啓動服務器和rebuild_index（manage.py rebuild_index）後，我得到以下錯誤。我一直在試圖解決問題，但沒有成功！我錯過了什麼？在粘貼新文件之前，我應該先刪除模式文件中的XML代碼嗎？

Answer 1

我不跑Solr的，因此不能對此進行測試，但有幾個問題我跳出（更準確地，被標記爲錯誤，當我嘗試到prettyprint的XML :-)）

• 線40（<!-- A Trie based date field ...）在->結束;應該是-->

• line 59（<filter class="solr.SynonymFilterFactory" ...）contains ignore Case="true";應該ignoreCase="true"（在ATTR名無空格）

如果您修復這些錯誤，它很可能會解決您的問題。

Answer 2

Django的草垛只支持Solr的3.5+

http://django-haystack.readthedocs.org/en/latest/backend_support.html#id1

如果您使用的Solr 1.4，該模式格式已經1.4和3.5
