前言：
在 Django 模板语言中变量用 {{ }}，逻辑用 {% %}
在 urls.py 中添加对应关系
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^test/', views.django_test),
]
普通变量：
在 views.py 中编写 django_test 函数
from django.shortcuts import render, redirect, HttpResponse
from app01 import models
# Django 模板语言变量
def django_test(request):
name = "John"
age = 28
return render(request, "test.html", {"name1": name, "age1": age}) # 通过字典形式传给 html
接下来写 test.html 页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Django 模板语言测试</title>
</head>
<body>
<h1>Django 模板语言测试</h1>
{{ name1 }} {{ age1 }}
</body>
</html>
运行效果：
如果是用不存在的变量名，将不会在页面显示
列表：
如果要显示列表成员的话需要使用循环来显示
views.py：
from django.shortcuts import render, redirect, HttpResponse
from app01 import models
# Django 模板语言变量
def django_test(request):
name = "John"
age = 28
hobby = ["Reading", "Basketball", "Movie", "Music"]
return render(request, "test.html", {"name1": name, "age1": age, "hobby_list": hobby})
test.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Django 模板语言测试</title>
</head>
<body>
<h1>Django 模板语言测试</h1>
<!-- 普通变量 -->
{{ name1 }} {{ age1 }}
<!-- 列表 -->
{% for hobby in hobby_list %}
{{ hobby }}
{% endfor %}
</body>
</html>
运行效果：
字典：
通过 {{ 字典名.key }} 来获取 value
views.py：
from django.shortcuts import render, redirect, HttpResponse
from app01 import models
# Django 模板语言变量
def django_test(request):
name = "John"
age = 28
hobby = ["Reading", "Basketball", "Movie", "Music"]
info = {"height": 188, "weight": 120}
return render(request, "test.html", {"name1": name, "age1": age, "hobby_list": hobby, "info": info})
test.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Django 模板语言测试</title>
</head>
<body>
<h1>Django 模板语言测试</h1>
<!-- 普通变量 -->
{{ name1 }} {{ age1 }}
<!-- 列表 -->
{% for hobby in hobby_list %}
{{ hobby }}
{% endfor %}
<!-- 字典 -->
{{ info.height }} | {{ info.weight }}
</body>
</html>
运行效果：
类：
类通过 {{ 对象名.属性 }} 来访问属性，通过 {{ 对象名.方法 }} 来实现方法
views.py：
from django.shortcuts import render, redirect, HttpResponse
from app01 import models
# 测试类 Animal
class Animal(object):
def __init__(self, specie, name):
self.specie = specie
self.name = name
def sleep(self):
return "%s is sleeping" %self.name
# Django 模板语言变量
def django_test(request):
name = "John"
age = 28
hobby = ["Reading", "Basketball", "Movie", "Music"]
info = {"height": 188, "weight": 120}
a1 = Animal("Cat", "Tom")
a2 = Animal("Dog", "Jim")
return render(
request,
"test.html",
{
"name1": name,
"age1": age,
"hobby_list": hobby,
"info": info,
"a1": a1,
"a2": a2,
})
test.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Django 模板语言测试</title>
</head>
<body>
<h1>Django 模板语言测试</h1>
<!-- 普通变量 -->
{{ name1 }} {{ age1 }}
<!-- 列表 -->
{% for hobby in hobby_list %}
{{ hobby }}
{% endfor %}
<!-- 字典 -->
{{ info.height }} | {{ info.weight }}
<br>
<!-- 类 -->
{{ a1.specie }} | {{ a1.name }} | {{ a1.sleep }}
<br>
{{ a2.specie }} | {{ a2.name }} | {{ a2.sleep }}
</body>
</html>
运行效果：
