2.编写更多视图
-
现在在
views.py里添加更多视图
from django.http import HttpResponse
# Create your views here.
def home(request):
return HttpResponse("Hello, Welcome to Home Page")
def project_list(request):
return HttpResponse('You\'re looking at the list of project list')
def register(request):
return HttpResponse('You\'re looking at the register page') -
把这些新视图添加进
urls模块里
# 作者：伊洛Yiluo 公众号：伊洛的小屋
# 个人主页：https://yiluotalk.com/
# 博客园：https://www.cnblogs.com/yiluotalk/
from django.urls import path
from . import views
urlpatterns = [
path('home/', views.home, name='index'),
path('project_list/', views.project_list, name='project list'),
path('register/', views.register, name='register'),
] - 分别输入网址查看结果
3. 写一个真正有用的视图
-
每个视图必须要做的只有两件事：返回一个包含被请求页面内容的 [
HttpResponse]对象，或者抛出一个异常，比如 [Http404] -
回到
views.py - 之前我们在管理后台添加过project的数据
- 来修改一下主页的代码
from django.http import HttpResponse
from .models import ProjectInfo
# Create your views here.
def home(request):
project_list = ProjectInfo.objects.order_by('add_data')[:5]
output = ', '.join([q.project_name for q in project_list])
return HttpResponse(output)
def project_list(request):
return HttpResponse('You\'re looking at the list of project list')
def register(request):
return HttpResponse('You\'re looking at the register page') -
打开网页查看
内容已经成功的展示
4.模板
- 虽然上面实现了暂时页面，但是存在一个比较严重的问题。内容是写在代码里面的，这样不适合管理。下面创建一个视图，就可以将页面的设计从代码中分离出来
-
首先来创建一个
templates目录，用来存放静态文件,再创建一个目录 autoapi，然后在其中新建一个文件home.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>AutoPlarform Home</title>
</head>
<body>
{% if project_list %}
<ul>
{% for project in project_list %}
<li>
<a href="/autoapi/register/">{{ project.project_name }}</a>
</li>
{% endfor %}
</ul>
{% endif %}
</body>
</html> -
下面在更新下
views.py
from django.http import HttpResponse
from django.template import loader
from .models import ProjectInfo
# Create your views here.
def home(request):
project_list = ProjectInfo.objects.order_by('add_data')[:5]
template = loader.get_template('autoapi/home.html')
context = {
'project_list': project_list,
}
return HttpResponse(template.render(context, request))
def project_list(request):
return HttpResponse('You\'re looking at the list of project list')
def register(request):
return HttpResponse('You\'re looking at the register page') - 我们来打开主页查看下有没有效果
- 信息成功的显示在了主页上
5.一个快捷函数： render()
-
Django 提供了一个快捷函数，我们用它来重写
views.py
from django.http import HttpResponse
from django.shortcuts import render
from .models import ProjectInfo
# Create your views here.
def home(request):
project_list = ProjectInfo.objects.order_by('add_data')[:5]
context = {'project_list': project_list}
return render(request, 'autoapi/home.html', context)
def project_list(request):
return HttpResponse('You\'re looking at the list of project list')
def register(request):
return HttpResponse('You\'re looking at the register page') - 再次刷新主页查看一下效果
- 同刚才是一个效果
