实现一个简单的模板应用案例

# 设置路由myproject/myapp/urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('myapp/index', views.index, name='index'),
]

# myproject/myapp/views.py
from django.shortcuts import render
from django.http import HttpResponse

def index(request):
    data = {'name': 'this is index'}
    return render(request, 'myapp/index.html', data)

# myproject/myapp/templates/myapp/index.html 没有的要新建目录和文件
<h1>{{ name }}</h1>

模板中if标签使用

# myproject/myapp/views.py
def index(request):
    data = {'time': 18}
    return render(request, 'myapp/index.html', data)

# myproject/myapp/templates/myapp/index.html
{% if time < 12 %}
<h3>上午好</h3>
{% elif time > 12 %}
<h3>下午好</h3>
{% else %}
<h3>中午好</h3>
{% endif %}

模板中for标签使用

# myproject/myapp/views.py
from myproject.myapp.models import User
def index(request):
    data = User.objects.all()
    list = {'list': data}
    return render(request, 'myapp/index.html', list)

# myproject/myapp/templates/myapp/index.html
<ul>
{% for val in list %}
<li>{{ val.first_name }}{{ val.last_name }}</li>
{% empty %}
<li>没有数据</li>
{% endfor %}
</ul>

模板中使用函数

# myproject/myapp/views.py
import datetime
def index(request):
    data = {'now': datetime.datetime.now()}
    return render(request, 'myapp/index.html', data)

# myproject/myapp/templates/myapp/index.html
<h1>{{ now|date:"Y-m-d" }}</h1>

模板中使用static静态文件

# myproject/settings.py
STATICFILES_DIRS = [ 
    BASE_DIR / "myproject/static", 
]

# 文件地址myproject/static/myapp/1.png

模板中使用static静态文件
{% load static %}
<img src="{% static 'myapp/1.png' %}"/>

模板中使用include标签

# myproject/myapp/templates/myapp/head.html
<h1>head.html</h1>

# myproject/myapp/templates/myapp/index.html
{% include './head.html' %}
<h2>index.html</h2>
