我设置了一个非常简单的项目来使用Whoosh引擎尝试Haystack,主要是遵循文档中的示例。我使用pip安装了所有内容,没有版本号,所以我应该有最新版本。
我收到了这个错误,我不知道我现在应该做什么,虽然我已经搜索过Google,但我找不到类似的东西。请帮忙!
项目文件夹结构非常简单,有一个名为cat的应用程序。
project |-cat | |-migrations | |-admin.py, apps.py, models.py, search_indexes.py |-templates | |-search | |-indexes | | |-cat | | |-cat_text.txt | |-search.html |-manage.py, settings.py, urls.py
我得到的错误是:

对于任何正在努力解决这个问题的人来说,这都归功于Django 1.9中的一点变化,其中get_model()
方法被移动到django.apps.apps
模块,并且django.db
模块不再可用1}}
现在Haystack社区已经解决了这个问题,因此从他们的GitHub存储库(而不是PyPI)更新到最新版本必须解决它。
以下内容应解决它:
pip install git+https://github.com/django-haystack/django-haystack.git
或者你可以像Sam建议的那样简单地降级到Django 1.8。 您可以在此问题here
