基于类的视图查询：获取另一个模型引用的对象 [英] Class based views query: get objects referenced by another model

问题描述

此问题扩展了
Django将多个模型传递给一个模板

我想生成1个模板，即我的个人资料索引页，因此它将列出url <中指定的用户创建的所有对象/ p>

我想查询一个模板的多个模型，获取有问题的概要文件，并显示由附加概要文件创建的所有oferto对象

views.py

  class ProfileIndex（ListView）：
 context_object_name ='account_list'
 template_name ='profiles / account_index.html'
 queryset = Profile.objects.all（）
 
 def get_context_data（self，** kwargs）：
 context = super （ProfileIndex，自身）.get_context_data（** kwargs）
 context ['profile'] = Profile.objects.all（）
 context ['oferto'] = Oferto.objects.get（kwargs.profile .slug）
 
返回上下文
  

urls.py我想我需要从url中获取配置文件信息，以便通过网址中的该用户

  url（
 regex = r ^ index /（？P< slug> [- _\w] +），
 view = ProfileIndex.as_view（），
 name = profile_index，
），
  

这是最难找出的，如何使我的模板从相关上下文中正常工作

  {％块内容％} 
 
< h1> {{个人资料}}< h1> 
< h2> Ofertoj或/aŭOffer< / h2> 
 {％for aerto in profile％} 
< a href = {％url oferto_detail oferto.slug％}> {{oferto.name}}< / a>< br /> 
 
 
 {％endfor％} 
 
 
 
 
 {％endblock％} 
  

解决方案

frontend / models.py

  Class Profile（models.Model）：
 .... 
 
 Class Oferto（models.Model）：
 profile = model。 ForeignKey（配置文件）：
 ... 
  

frontend / views.py

  Class ViewProfileList（ListView）：
模型=配置文件
 template_name ='frontend / view_profile_list.html'
  

frontend / templates / frontend / view_profile_list.html

  {％为object_list.profile中的配置文件。所有％} 
 {％为profile.oferto_set.all％中的销售者} 
 {{ofer.you_field}} 
 { ％endfor％} 
 {％endfor％} 
  

this question extends Django Pass Multiple Models to one Template

In that I want to produce 1 template, that is my profile index page, so it will list all the objects created by the user specified in the url

I want to query multiple models for one template, get the Profile in question and show all the oferto objects that was created by the attached profile

views.py

class ProfileIndex(ListView):
context_object_name = 'account_list'    
template_name = 'profiles/account_index.html'
queryset = Profile.objects.all()

def get_context_data(self, **kwargs):
    context = super(ProfileIndex, self).get_context_data(**kwargs)
    context['profile'] = Profile.objects.all()
    context['oferto'] = Oferto.objects.get(kwargs.profile.slug)

    return context

urls.py I am thinking I need to get the profile slug from the url in order to search for all oferto by that user in the url

url(
regex=r"^index/(?P<slug>[-_\w]+)",
view=ProfileIndex.as_view(),
name="profile_index",
),

And this has been the hardest to figure out, how to make my template work correctly from the context in question

{% block content %}

<h1>{{ profile }}<h1>
    <h2> Ofertoj or/aŭ Offers</h2>
    {% for oferto in profile  %}
        <a href="{% url "oferto_detail" oferto.slug %}">{{ oferto.name }}</a><br/>


    {% endfor %}




{% endblock %}

解决方案

frontend/models.py

Class Profile(models.Model):
   ....

Class Oferto(models.Model): 
   profile = model.ForeignKey(Profile):
   ...

frontend/views.py

Class ViewProfileList(ListView):
    model = Profile
    template_name = 'frontend/view_profile_list.html'

frontend/templates/frontend/view_profile_list.html

  {% for profile in object_list.all %}
      {% for ofer in profile.oferto_set.all %}
         {{ ofer.you_field }}
      {% endfor %}
  {% endfor %}
