我正在尝试制作一个用户面板,其中显示每个用户的个人资料信息(如头像、加入日期等)以及他们的帖子。这是呈现线程的 View :
def topic(request, topic_id):
"""Listing of posts in a thread."""
posts = Post.objects.select_related('creator') \
.filter(topic=topic_id).order_by("created")
posts = mk_paginator(request, posts, DJANGO_SIMPLE_FORUM_REPLIES_PER_PAGE)
topic = Topic.objects.get(pk=topic_id)
topic.visits += 1
topic.save()
return render_to_response("myforum/topic.html", add_csrf(request, posts=posts, pk=topic_id,
topic=topic), context_instance=RequestContext(request))
主题模型是:
class Topic(models.Model):
title = models.CharField(max_length=100)
description = models.TextField(max_length=10000, null=True)
forum = models.ForeignKey(Forum)
created = models.DateTimeField()
creator = models.ForeignKey(User, blank=True, null=True)
visits = models.IntegerField(default = 0)
和 UserProfile 模型:
class UserProfile(models.Model):
username = models.OneToOneField(User)
name = models.CharField(max_length=30, blank=True)
city = models.CharField(max_length=30, blank=True)
country = models.CharField(
max_length=20, choices= COUTNRY_CHOICES, blank=True)
avatar = ImageWithThumbsField(), upload_to='images', sizes=((32,32),(150,150),(200,200)), blank=True)
created_at = models.DateTimeField(auto_now_add=True, blank=True)
updated_at = models.DateTimeField(auto_now=True, blank=True)
问题是如何最好地连接这两个表,以便 userprofile 字段可以与用户名一起显示在 topic.html 中?
将它们添加到上下文中,因为您已经有了数据库关系用户和主题。
# add this to context
topic = Topic.objects.get(pk=topic_id)
creator = topic.creator.get().profile # This pulls the user object from creator field
context['creator'] = creator # Add to context
现在您可以使用“创建者”上下文来拉取字段
<h1>{{ creator.name }}</h1>
至于头像,如果您在设置中设置了媒体根目录,您只需使用一个
<img src="/media/images/{{ creator.avatar }}">
哦,您还可以通过使用 Django 基于类的 View 的 ListView 和 DetailView 部分来节省大量时间。
抱歉忘了说你应该给你的一对一添加一个相关的名字,
username = OneToOneField(User, related_name='profile')
我是一名优秀的程序员,十分优秀!
