Flask-admin内联建模传递表单参数抛出AttributeError [英] Flask-admin inline modelling passing form arguments throws AttributeError

问题描述

在Flask-admin中，我现在尝试在模型视图中实现内联模型编辑。在模型方面，我有一个简单的树结构，代表一组内容页面。每个节点都有几个子节点，还有几个与之关联的内容数据模型。模型被命名为 ContentNode 和 ContentData 。

我使用Docs inline_models / mod_contrib_sqla /rel =nofollow>这里，它似乎开始正常工作。

 ＃AuthModelView （Model.ContentData，）
 简单的ModelView和用户认证
 class ContentNodeModelView（AuthModelView）：
 ... 
 
 inline_models =然而，只要我尝试将属性传递给内联表单，使用 
 
 <$ p $ 
  $ b> p>  inline_models = [（models.ContentData，dict（form_columns = ['title'，'text']））] 
  

Flask服务器给出

  AttributeError：'ContentDataForm'对象没有属性'id '
  

我在这里丢失了超级明显的东西吗？有没有在文档中的错误，因为它听起来像也许 inline_models 期待一个模型，但得到一个字典？

我绝对检查过它与文档中的一样。

非常感谢任何帮助。感谢：）

解决方案

您忘记指定id，它用于内联窗体构造。
尝试添加'id'属性：

$ p $ in $ inline_models = [（models.ContentData，dict（form_columns = [ 'id'，'title'，'text']）]]

Hi there fellow Flask developers!

In Flask-admin, I currently try to implement inline model editing into my model view. On the model side, I have a simple tree structure that represents a set of content pages. Each node has several child nodes and also several content data models associated with it. The models are named ContentNode and ContentData.

If I use the inline_models property on the node view class as described in the Docs here, it seems to work fine at first.

# AuthModelView is simply ModelView with user authentification
class ContentNodeModelView(AuthModelView):
    ...

    inline_models = (models.ContentData, )

However, as soon as I try to pass properties to the inline form, using

inline_models = [(models.ContentData, dict(form_columns=['title', 'text']))]

the Flask server gives

AttributeError: 'ContentDataForm' object has no attribute 'id'

Am I missing something super obvious here? Is there maybe a mistake in the documentation because it sounds like maybe inline_models expects a model but gets a dictionary?

I definitely checked that it's the same as in the docs.

Any help is greatly appreciated. Thanks :)

解决方案

You forgot to specify id, which uses for inline-form construction. Try to add 'id' attribute in:

inline_models = [(models.ContentData, dict(form_columns=['id', 'title', 'text']))]
