二.

views

三种形式 ,

1.HttpResponse("字符串")

2.ebder("页面")

--读取文件字符串 (在django中本身会自动读取文件)

--渲染变量

1 from django.shortcuts import render
2 
3 # Create your views here.
4 def index(request):
5     sp=["好吃的","好玩的","好看的"]
6     name="ales"
7     return render(request,"index.html",{"name":name})

views

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <title>Title</title>
 6 </head>
 7 <body>
 8 <p>{{ name }}</p>
 9 
10 <p>{{ sp }}</p>
11 </body>
12 </html>

index.html

3.redirect() #重定向

比如在登陆成功的时候,会显示success,这样也太客气了,所以重定向即使直接跳转到登陆后的页面

django可以通过redirect来实现 ,

 1 from django.shortcuts import render,HttpResponse,redirect
 2 
 3 # Create your views here.
 4 def index(request):
 5 
 6     return render(request,"index.html")
 7 
 8 def login(request):
 9     print("method", request.method)
10     if request.method=="GET":
11         # with open("templates/login.html","r",encoding="utf8") as f:
12         #     data=f.read()
13         #
14         # return HttpResponse(data)
15 
16         return render(request, "login.html")
17 
18     else:
19 
20         print("method",request.method)
21         print(request.POST) # <QueryDict: {'user': ['root'], 'pwd': ['root1234']}>
22         user=request.POST.get("user")
23         pwd=request.POST.get("pwd")
24         print(user,pwd)
25 
26         if user=="alex" and pwd=="123":
27             return redirect("/index/")
28         return HttpResponse("error")

views

1 from django.contrib import admin
2 from django.urls import path
3 from app01 import  views
4 
5 urlpatterns = [
6     path('admin/', admin.site.urls),
7     path('index/', views.index),
8     path('login/',views.login)
9 ]

urls

三.

templates 模板

模板语法由render渲染

关于

<div class="col-md-9">
    {% block content %}
        <h3>welcome!</h3>


    {% endblock content%}
</div>
----------------------------

{% extends "base.html" %}

{% block content %}
    {{ block.super }}

   <div class="jumbotron">
      <h1>Hello, world!</h1>
      <p>...</p>
      <p><a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a></p>
    </div>
{% endblock %}
