Create custom Values method in django

Question

I want to create a method semi to values method in Django QuerySet.

The values method problems are:

1. Miss order of fields in querySet if I make myquery = MyModel.objects.values('field1','field2','field3') when i print querSet it give me [{'field2':'data','field1':'data','field3':'data'},...]. so this miss order will cause a problem at Union of queryset.
2. if the field is choices at model then values(...) will give me the key of dictionary instead of its value.

• I want to create my custom values method using django Manager

  
  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()
