模板的继承，与导入: extends, block
模板的继承
模板的总体固定不变，但是用户点击登录或注册，页面只变化两个模块位置。
Views.py
def home(request):
return render(request,'home.html')
def login(request):
return render(request,'login.html')
def reg(request):
return render(request,'reg.html')
Login.html
{% extends 'home.html' %}
{% block content %}
<h1 class="text-center">注册</h1>
<form action="" method="post">
<p>username: <input type="text" name="username" class="form-control"></p>
<p>password: <input type="text" name="password" class="form-control"></p>
<input type="submit" class="btn btn-block">
</form>
{% endblock %}

一般情况下末班页面上至少有三块可以被修改的区域
- css区域
- html区域
- js区域
{% block css %}
{% endblock %}
{% block content %}
{% endblock %}
{% block js %}
{% endblock %}
# 每一个子页面就都可以有自己独有的css代码 html代码 js代码
"""
一般情况下 模版的页面上划定的区域越多 那么该模版的扩展性就越高
但是如果太多 那还不如自己直接写
"""
模板的导入
"""
将页面的某一个局部当成模块的形式
哪个地方需要就可以直接导入使用即可
"""
{% include 'wasai.html' %}
