Python Dango 4.2.5教程：渲染HTML模板页面（使用HttpResponse和loader来渲染）

目录结构

vim django-20231002/mysite/polls/views.py

from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def index(request):
    return HttpResponse('hello django polls index')

def q_detail(request,question_id):
    return HttpResponse('you are looking for %s.'%question_id)

def results(request, question_id):
    response = "You're looking at the results of question %s."
    return HttpResponse(response % question_id)

def vote(request, question_id):
    return HttpResponse("You're voting on question %s." % question_id)

from django.template import loader
from .models import Question

def latest_question_list(request):
    latest_question_list = Question.objects.order_by('-published_time')[:5]
    template = loader.get_template('polls/index.html')
    context = {
        'latest_question_list': latest_question_list,
    }
    return HttpResponse(template.render(context, request))

vim django-20231002/mysite/polls/urls.py

from django.urls import path
from . import views

urlpatterns=[
    path('index/',views.index,name='index'),
    path('<int:question_id>/',views.q_detail),
    # ex: /polls/5/results/
    path('<int:question_id>/results/', views.results, name='results'),
    # ex: /polls/5/vote/
    path('<int:question_id>/vote/', views.vote, name='vote'),
    path('latest_question_list/',views.latest_question_list,name='latest_question_list'),
]

vim django-20231002/mysite/polls/templates/polls/index.html

{% if latest_question_list %}
    <ul>
    {% for question in latest_question_list %}
        <li><a href="/polls/{{ question.id }}/">{{ question.question_text }}</a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No polls are available.</p>
{% endif %}
