django - 在 django 中创建自定义值方法

Question

我想在 Django QuerySet 中创建一个方法 semi to values 方法。

值方法问题是：

1. 如果我在打印 querSet 时将myquery = MyModel.objects.values('field1','field2','field3') 设为[{'field2':'data','field1': 'data','field3':'data'},...]。所以这个未命中的订单会导致查询集联合出现问题。
2. 如果该字段是模型中的选择，那么values(...) 会给我字典的键而不是它的值。

• 我想使用 django Manager 创建我的自定义值方法

  
  class MyModelManager(models.Manager):
      def values(self, *fields):
          # I want to get model belong to this manger
          # then I want to check the fields if its in models (we have fields came from annotate)
          # after that I want to exclude to the fields that has choices 
          # next I want to call the super values method and passed to it the values that does not have choices
          # finally I want to reorder query according to passed fields
  
  class MyModel(models.model):
      # An example model
      objects = MyModelManager()
