在Django的一个视图中显示多个模型

我是Django的初学者,我有一个问题.... 我创建了一个包含3个模型的应用程序(名称:PQR)(患者/问题/回复) 我想在顶部看到患者姓名的视图,在此之下,所有可用的问题以及问题旁边的答案(某些患者可能有空回复/无回复)。 我知道如何显示患者的答案,但我想显示每个问题,如果有的话,我想提供答复,但我不知道如何在我看来写这个?

这是我的模特:

Class Patient(models.Model):
    name = models.CharField(max_length=50)

def __unicode__(self):
    return self.name

def listReply(self):
    replies = Reply.objects.filter(patient= self.id)
    return replies

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

def __unicode__(self):
    return self.question_text


class Reply(models.Model):
    question = models.ForeignKey(Question)
    patient = models.ForeignKey(Patient)
    reply_text = models.CharField(max_length=200)

def __unicode__(self):
    return str(self.reply_text)

这是我的观点:

from django.shortcuts import render, get_object_or_404
from django.template import RequestContext
from .models import Patient, Question, Reply

def list(request):
    list_patient = Patient.objects.order_by('name') context = RequestContext(request, {'list_patient':list_patient,'welcome': 'Welcome on my page Django !',
})
return render(request, 'PQR/list.html', context)

def detail(request, patient_id):
    patient = get_object_or_404(Patient, pk=patient_id)
    list_question = Question.objects.all()
    Replies4MyPatient = Reply.objects.filter(patient=patient_id)
    return render(request, 'PQR/detail.html', locals())

这是我的网址:

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.list, name ='list_patient'),
    url(r'^(?P<patient_id>[0-9]+)/patient/$', views.detail, name ='detail_patient'),

这是我的模板:

{% load staticfiles %} 
<link rel="stylesheet" type="text/css" href="{% static 'Forum/style.css' %}" /> 
<div> 
<h1>Patient details : {{ patient }}</h1>    
</div> 
<fieldset> 
{% csrf_token %} 
{% for reply in Replies4MyPatient %} 
        </br><abcd>{{ reply.question }}</abcd></br> 
        </br> 
            <li>{{ reply }}</li> 
{% endfor %} 
</fieldset></br> 
<a href="{% url 'list_patient' %}"/> <input type="button" value="Look Back"/> 

感谢您的帮助!

函数render构建html以返回模板和上下文。在您的模板PQR/detail.html中,您使用{{ patient }}Replies4MyPatient。您需要使用这些值构建上下文并将其传递给render

def detail(request, patient_id):
    patient = get_object_or_404(Patient, pk=patient_id)
    list_question = Question.objects.all()
    Replies4MyPatient = Reply.objects.filter(patient=patient_id)
    context = {'patient' : patient, 'Replies4MyPatient' : Replies4MyPatient}
    return render(request, 'PQR/detail.html', context=context)
