如何使用Flask-Admin ModelView过滤编辑窗体中的列？

问题描述

我用flask-admin使用模型视图，我想在编辑/创建视图中过滤一列。列/字段是一种关系，我只想显示属于已登录用户的字段，即 relationship_id == user.id

  class CustomModelView（ModelView）：
 form_args = dict （
 status = dict（label ='Status'，query_factory = filtering_function）
）
 $ b $ def filter_function（）：
返回app.db.query（CustomModel） .filter_by（field_to_filter = my_criteria）
  

I am using a model view with flask-admin and I want to filter a column in the edit/create view. The column/field is a relationship and I only want to show fields that belong to the logged in user i.e. relationship_id == user.id

解决方案

Actually I found a easier way for that as below, seems there's no need to override the edit_form method in ModelView, just pass the filtering function as a named parameter(query_factory) to the form_args, and it works like a charming!.

class CustomModelView(ModelView):
    form_args = dict(
        status = dict(label='Status', query_factory=filtering_function)
    )

def filtering_function():
   return app.db.query(CustomModel).filter_by(field_to_filter=my_criteria)
