django路由系统

Posted 2020-09-10 xone

一、路由系统，URL

    1、url(r‘^index/‘, views.index),    
       url(r‘^home/‘, views.Home.as_view()),
    2、url(r‘^detail-(\d+).html‘, views.detail),  
    3、url(r‘^detail-(?P<nid>\d+)-(?P<uid>\d+).html‘, views.detail)
       
       PS:
            def detail(request, *args,**kwargs):
                pass
    
       实战：
            a. 
                url(r‘^detail-(\d+)-(\d+).html‘, views.detail),
                
                def func(request, nid, uid):
                    
                    pass
            
                def func(request, *args):
                    args = (2,9)
                    
                    
                def func(request, *args, **kwargs):
                    args = (2,9)
       
            b. 
                url(r‘^detail-(?P<nid>\d+)-(?P<uid>\d+).html‘, views.detail)
                
                def func(request, nid, uid):
                    pass
                    
                def funct(request, **kwargs):
                    kwargs = {‘nid‘: 1, ‘uid‘: 3}
                    
                def func(request, *args, **kwargs):
                    args = (2,9)
    4、 name
        
        对URL路由关系进行命名， ***** 以后可以根据此名称生成自己想要的URL *****
        
        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‘),
        
        
        
        def func(request, *args, **kwargs):
            from django.urls import reverse
            
            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/
        
        注：
            # 当前的URL
            request.path_info 
    5、多级路由
        
        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),
            ]
