按日期排序所有信息DJANGO

Question

我在HelloWebApp书中有一个名为“Thing”的模型。现在我添加了一个“重量”模型。该模型的字段为“日期”和“weight_value”。在“thing_detail.html”中显示数据时，我想显示按“日期”字段排序的数据。

这里是我的models.py

from django.db import models 
from django.contrib.auth.models import User 
from django.db import models 
from django.utils import timezone 

class Thing(models.Model): 
    name = models.CharField(max_length=255) 
    description = models.TextField() 
    slug = models.SlugField(unique=True) 
    user = models.OneToOneField(User, blank=True, null=True) 

class Weight(models.Model): 
    date = models.DateTimeField(default=timezone.now) 
    weight_value = models.CharField(max_length=255) 
    thingRA = models.ForeignKey(Thing,related_name="weights") 

    class Meta: 
     order_with_respect_to = 'thingRA' 

和thing_details.html

{% extends 'layouts/base.html' %} 
{% block title %} 
{{ thing.name }} - {{ block.super }} 
{% endblock %} 
{% block content %} 
<div id="content"> 
<!-- Below is to check if the data belongs to the original user --> 
{% if user == thing.user %} 
<h1>{{ thing.name }}</h1> 
<p>{{ thing.description }}</p><br> 
{% if weights %} 
    {% for weightshow in weights %} 
     <p>>Weight as on {{weightshow.date}} : {{weightshow.weight_value}}</p> 
    {% empty %} 
     <p>Sorry! You haven't logged any weight records yet</p> 
    {% endfor %} 
{% endif %} 
<br><br> 
<a href="{% url 'edit_thing' slug=thing.slug %}"><u>Edit Me!</u></a> 
<br> 
<a href="{% url 'edit_weight' slug=thing.slug %}"><u>Log Weight Record!</u></a> 
</div> 
{% else %} 
<h1>Error!</h1> 
<p>You do not have the permission to view this account. If this is your account please logout and login to <strong>{{thing.name}}</strong></p><br> 
{% endif %} 
{% endblock %} 

请别人帮忙！

谢谢！

你的体重，当你正在查询添加ORDER_BY（）模型

class Meta: 
    ordering = ['date'] 

或添加此。赞，

Weight.objects.all().order_by('date')
