Python 使用django imagekit不会保存或显示图像

从桌面为用户设置加载特定图像后，生成要显示的特定图像时出现问题。当我按save时，图像不会出现，也不会为特定用户保存在我的数据库中

我希望图像在单击“保存”后显示，并将生成的图像存储在我指定的路径文件和数据库中。下面是一些代码片段，有助于排除故障。任何帮助都将不胜感激

谢谢大家!

你能包括你的进口声明吗？我的第一个想法是，在表单和模型中都不需要ProcessedImageField。还有两个不同的ProcesseImage字段类—表单字段和模型字段。确保您在正确的位置使用了正确的语句。@MatthewWithann刚刚添加了我的导入语句！你有什么错误吗？此外，模型是否根本不保存，或者图像缩略图字段是否为空？有一件事你必须改变，那就是不要同时使用表单字段和模型字段。如果要使用表单字段，只需在模型中使用常规ImageField；如果要使用模型字段，请在表单中使用常规（表单）图像字段。
