6)django-示例(fbv)

FBV(function base view),即一个url对应views.py一个函数

示例演示如下

　　1）FBV如何使用

　　2）渲染页面，并返回字典数据

　　3）字典数据页面如何访问

1）url.py

from app01 import views

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^index/', views.index),

    url(r'^login/', views.login),

    url(r'^home/', views.Home.as_view()),

    url(r'^detail-(\d+).html',views.detail), #动太路由

]

2)views.py

USER_DICT={
    "1":{"name":"root","email":"[email protected]" },
    "2":{"name":"root","email":"[email protected]" },
    "3":{"name":"root","email":"[email protected]" },
    "4":{"name":"root","email":"[email protected]" },

}

def index(request):

    return render(request,"index.html",{"USER_DICT":USER_DICT})

3)模板index.html

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

    <ul>

        {% for row in USER_DICT %} <!-- 这里返回的是KEY-->

        <li>{{ row }}</li>

        {% endfor %}

            {% for row in USER_DICT.keys %} <!-- 这里返回的是KEY-->

        <li>{{ row }}</li>

        {% endfor %}

            {% for row in USER_DICT.values %} <!-- 这里返回的是values-->

        <li><a href="/detail/?id={{ row }}">{{ row }}</a></li>

        {% endfor %}

                {% for k,v in USER_DICT.items %} <!-- 这里返回的是key,values-->

        <li><a href="/detail-{{ k }}.html">{{ v.name }}</a></li>

        {% endfor %}

    </ul>

</body>

</html>
