无法将关键字“商品”解析为字段。选择是：id，name

标签： python django django-models virtualenv photologue

我正在使用photologue用django创建照片库网站。我在我的virtualenv中安装了django-tagging，不知道它不再受photologue的支持。现在，在执行迁移后，每当我尝试添加照片或查看照片时，我都会在/ admin / photologue / photo / upload_zip /获得FieldError 无法将关键字“商品”解析为字段。选择是：id，name。

我卸载并重新安装了django，photologue，SQLite文件，并删除了django-tagging，但问题仍然存在。我还尝试运行一个使用photologue并共享virtualenv的不同项目，并且提示我执行相同（假设破坏性）迁移。

如果问题跨越多个项目且所有依赖项都已重新安装，我无法弄清楚我的系统上可能发生的变化。

这个问题似乎是因为django-tagging在某种程度上仍然出现在virtualenv上。

在photologue保存模型后的追溯中，django-tagging会对发送的信号作出反应并尝试更新任何相关标签：

File "/home/cameron/Envs/photologue/local/lib/python2.7/site-packages/django/dispatch/dispatcher.py" in send
  198.             response = receiver(signal=self, sender=sender, **named)
File "/home/cameron/Envs/photologue/local/lib/python2.7/site-packages/tagging/fields.py" in _save
  81.             Tag.objects.update_tags(kwargs['instance'], tags)
File "/home/cameron/Envs/photologue/local/lib/python2.7/site-packages/tagging/models.py" in update_tags
  34.                                         items__object_id=obj.pk))

它尝试使用（显然不再存在）字段items，以及发生错误的地方。

我猜你在venv上卸载django-tagging的方式并没有真正起作用。您是否已卸载：pip uninstall django-tagging？

作为参考，这里再次发表我的评论/重建venv的步骤

...如果您的venv以某种方式被破坏，最简单的方法是从头开始重建：

  1. 在你的venv上：

    env pip freeze > orig_requirements.txt

    检查orig_requirements.txt并删除您不需要的所有内容。

  2. 制作一个没有站点包的新venv并重新安装要求：

    mkvirtualenv --no-site-packages photoenv

    pip install -r orig_requirements.txt

  3. 现在，在运行你的django项目时，请仔细检查你的这个venv

    workon photoenv

错误很简单 - 因为您要求数据库中不存在的字段。由于您还没有发布代码，因此很难具体而言。是否构建了一个模板，引用了一个名为＆＃39; items＆＃39;那不再存在？
