python - Haystack 和 Solr- 架构解析失败

Question

我正在尝试重建索引，但在构建模式 (manage.py build_solr_schema) 之后，我将输出复制并粘贴到 schema.xml 文件中。重新启动服务器和 rebuild_index ( manage.py rebuild_index ) 后，我收到以下错误。我一直在努力解决问题，但没有成功!我错过了什么？在粘贴新代码之前，我应该先删除架构文件中的 XML 代码吗？

  HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: <abortOnConfigurationError>false</abortOnConfigurationError> in solr.xml -------------------------------------------------------------

Answer 1

Django Haystack 仅支持 Solr 3.5+

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

如果您使用的是 Solr 1.4，模式格式在 1.4 和 3.5 之间发生了变化
