运行"./manage.py rebuild_index"时出现django-haystack错误

Question

我在运行时遇到了下面的类型错误：

python manage.py rebuild_index

我现在的环境是 Solr 4.8.1、django-haystack 2.1.0、Django 1.6.2 和 Python 3.4.0。

有没有人知道这可能是什么原因造成的？以下是错误的详细信息：

Answer 1

在我的情况下，出现了一个关于 django_id 的问题。对我有帮助的是 这个 问题。我做了以下几件事：

• 把模式文件放到 solr-x.y.z/example/solr/collection1/conf/schema.xml 这个位置。

• 在 fields 部分给模式添加一个版本字段（如下所述）：

<field name="django_id" type="string" indexed="true" stored="true" multiValued="false"/>
