如何编写排序功能

Question

我有一个字段，我必须在Meta类中编写函数，该函数在我的字段字段中排序了我的日期。请帮我

from django.db import models 

class Aaa(models.Model): 
    fields = models.IntegerField() 

    class Meta: 
     app_label = 'project' 

Answer 1

我建议有一个长期，集中阅读文档，尤其是：https://docs.djangoproject.com/en/dev/ref/models/options/#django.db.models.Options.ordering

class Tag(models.Model): 
    test_case_counter = models.IntegerField(default=0) 
    my_date_field = models.DateField(auto_now=True,auto_add=True) 

    class Meta: # notice indentation 
     ordering = ['my_date_field'] 
     app_label = 'project'
