Question

我有一个字段，我必须在Meta类中编写函数，在我的字段字段中对我的日期进行排序。请帮帮我

from django.db import models

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

    class Meta:
        app_label = 'project'

我建议您仔细阅读文档，特别是：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'
