Django的URL寫法

一、Django基於正則表達式的URL

# url(r'^detail-(\d+)-(\d+).html', views.detail),  #這和下面的區別是，這兩個數可能會變，按照先后順序獲取
# url(r'^detail-(?P<nid>\d+)-(?P<uid>\d+).html', views.detail),    #寫死了nid 和uid,接收的參數也要對應着，根據ID一一對應獲取（盡量用這種）

def detail(request，nid,uid):　　
　　pass

多個參數時，可以使用這種方式接收參數：def detail(request, *args,**kwargs):

urls.py

 url(r'^detail/', views.detail),   #改前

 url(r'^detail-(\d+).html', views.detail), #改后，路由url寫得好看一點

 

views.py

 def detail(request):  #改url.py前的操作
     nid = request.GET.get('nid')
     detail_info = USER_DICT[nid]
     return render(request, 'detail.html',{'detail_info':detail_info})



def detail(request,nid):   #改url.py后的操作    url傳了+d參數，所以這邊也要接收一下
    detail_info = USER_DICT[nid]
    return render(request, 'detail.html',{'detail_info':detail_info})

 

detail.html

        {% for k,row in user_dict.items %}   {#  改url.py前獲取的路由?   ,看起來以為是動態的 #}
            <li><a target="_blank" href="/detail/?nid={{ k }}">{{ row.name }}</a></li>#}
        {% endfor %}




    {% for k,row in user_dict.items %}    {#  改url.py后獲取的路由-#}
        <li><a target="_blank" href="/detail-{{ k }}.html">{{ row.name }}</a></li> {% endfor %} 

 

 

 

 

 

 

二、對URL路由關系進行命名， ***** 以后可以根據此名稱生成自己想要的URL *****

urls.py

url(r'^asdfasdfasdf/', views.index, name='i1'),
url(r'^yug/(\d+)/(\d+)/', views.index, name='i2'),
url(r'^buy/(?P<pid>\d+)/(?P<nid>\d+)/', views.index, name='i3'),

 

views.py

from django.urls import reverse

def func(request, *args, **kwargs):

　　url1 = reverse('i1') # asdfasdfasdf/
　　url2 = reverse('i2', args=(1,2,)) # yug/1/2/
　　url3 = reverse('i3', kwargs={'pid': 1, "nid": 9}) # buy/1/9/

 

xxx.html

{% url "i1" %} # asdfasdfasdf/
{% url "i2" 1 2 %} # yug/1/2/
{% url "i3" pid=1 nid=9 %} # buy/1/9/

{#因為urls.py文件中，路由多添加了name='indexx',所以可以通過這種方式來讀取路由跳轉，防止路由連接改名字也不受影響#}

<form action="{% url 'indexx' 2 %}" method="post">   {# 如果帶有參數，這種跳轉方式也不是很好，因為不是動態跳轉，一直強制在2頁面#}
<form action="{% url 'indexx' nid=1 uid=3 %}" method="post">   {# 如果帶有參數，這種跳轉方式也不是很好，因為不是動態跳轉，一直強制在1/3頁面#}

    <p><input type="text" name="user" placeholder="用戶名："></p>
    <p><input type="text" name="email" placeholder="郵箱："></p>
        <input type="submit" value="提交">#}

<form action="{{ request.path_info }}" method="post">  {#動態生成url,沒上面方式這么死板#}

 

注：
# 當前的URL
request.path_info

 

 

 

 

三、多級路由分發，include()

project/urls.py

from django.conf.urls import url,include
from django.contrib import admin

urlpatterns = [
　　url(r'^cmdb/', include("app01.urls")),
　　url(r'^monitor/', include("app02.urls")),
]

 

app01/urls.py

from django.conf.urls import url,include
from django.contrib import admin
from app01 import views

urlpatterns = [
　　url(r'^login/', views.login),
]

 

app02/urls.py

from django.conf.urls import url,include
from django.contrib import admin
from app02 import views

urlpatterns = [
url(r'^login/', views.login),
]

 

 

 

 

寫在最后：

    url(r'^business/$',views.business),   #最好加上終止符$，否則如：url(r'^business_add/',views.business)不會識別到
