24.Django路由规则
路由规则
1.基于正则的url
在templates目录下创建index.html、detail.html文件
(1)index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% for k,value in user_dict.items %}
<li><a href="/detail-{{ k }}.html" target="_blank">{{ value.name }}</a></li>
{% endfor %}
</body>
</html>(2)idetail.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h2>详细信息</h2>
<h4>用户名：{{ detail_info.name }}</h4>
<h4>邮箱：{{ detail_info.email }}</h4>
</body>
</html>(3)views
from django.shortcuts import render,HttpResponse
USER_DICT = {
'1':{'name':'root1','email':'root1@xxx.com'},
'2':{'name':'root2','email':'root2@xxx.com'},
'3':{'name':'root3','email':'root3@xxx.com'},
'4':{'name':'root4','email':'root4@xxx.com'},
}
def index(request):
return render(request,'index.html',{'user_dict':USER_DICT})
def detail(request,nid):
detail_info = USER_DICT[nid]
return render(request, "detail.html", {"detail_info": detail_info})(4)urls
from django.conf.urls import url
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index/', views.index),
url(r'^detail-(\d+).html/', views.detail),
]2.正则url分组
(1)url修改
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index/', views.index),
url(r'^detail-(?P<nid>\d+)-(?P<uid>\d+).html/', views.detail),
]（2）views修改
url中是一个字典的格式，分组对应 {'nid':'\d+','uid':'\d+'}
def detail(request,**kwargs):
print(kwargs)
# {'nid':1,'uid':4}
nid = kwargs.get('nid')
detail_info = USER_DICT[nid]
return render(request, "detail.html", {"detail_info": detail_info})(3)login中也要对应
{% for k,value in user_dict.items %}
<li><a href="/detail-{{ k }}-4.html" target="_blank">{{ value.name }}</a></li>
{% endfor %}3.request.path_info获取当前客户端访问的路劲
（1）urls
from django.conf.urls import url,include
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r'^index', views.index),
](2)views
def index(request):
print(request.path_info) #获取客户端当前的访问链接
# / index
return render(request,"index.html",{"user_dict":USER_DICT})(3)inde.html
==> action="{{ request.path_info }}<form action="{{ request.path_info }}" method="post">
<p><input name="user" type="text" placeholder="用户名"/></p>
<p><input name="password" type="password" placeholder="密码"/></p>
<p><input type="submit" value="提交"/></p>
</form>4.name
对路由关系进行命名，根据此名称生成自己想要的URL
views
def index(request,*args,**kwargs):
return render(request,"index.html")urls
from django.conf.urls import url
from django.contrib import admin
from cmdb import views
urlpatterns = [
# url(r'^first/', views.index, name='i1'), #第一种
# url(r'^second/(\d+)/(\d+)/', views.index,name='i2'), #第二种
url(r'^third/(?P<pid>\d+)/(?P<nid>\d+)/',views.index,name='i3'), #第三种
]index.html
第一种
<form action="{% url 'i1' %}" method="post">
第二种
<form action="{% url 'i2' 1 2 %}" method="post">
第三种
<form action="{% url "i3" pid=1 nid=9 %}" method="post">
<p><input name="user" type="text" placeholder="用户名"/></p>
<p><input name="password" type="password" placeholder="密码"/></p>
<p><input type="submit" value="提交"/></p>
</form>5.路由分发
主程序urls.py
from django.conf.urls import url,include
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^cmdb/', include('cmdb.urls')),
]cmdb下的urls.py
from django.conf.urls import url
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r'^time/',views.time),
]访问： http://127.0.0.1:8000/cmdb/time/
