通过上节课的学习，我们已经对Django有了简单的了解，现在来深入了解下~
1.1 单一路由对应
url(r‘^index$‘, views.index),
1.2 基于正则的路由
url(r‘^index/(\d*)‘, views.index), url(r‘^manage/(?P<name>\w*)/(?P<id>\d*)‘, views.manage),
from django.conf.urls import url,include
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r‘^index‘, views.index),
url(r‘^detail-(\d+).html/‘, views.detail),
]
USER_DICT = {
‘1‘:{‘name‘:‘root1‘,‘email‘:‘root@live.com‘},
‘2‘:{‘name‘:‘root2‘,‘email‘:‘root@live.com‘},
‘3‘:{‘name‘:‘root3‘,‘email‘:‘root@live.com‘},
‘4‘:{‘name‘:‘root4‘,‘email‘:‘root@live.com‘},
}
def index(request):
return render(request,"index.html",{"user_dict":USER_DICT})
def detail(request,nid): # nid指定的是(\d+)里的内容
detail_info = USER_DICT[nid]
return render(request, "detail.html", {"detail_info": detail_info})
1.3 url分组
在url.py增加对应路径
from django.conf.urls import url,include
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r‘^index‘, views.index),
url(r‘^detail-(?P<nid>\d+)-(?P<uid>\d+).html/‘, views.detail),<br> # nid=\d+ uid=\d+
]
在views.py文件创建对应方法
def detail(request,**kwargs):
print(kwargs)
#{‘nid‘: ‘4‘, ‘uid‘: ‘3‘}
nid = kwargs.get("nid")
detail_info = USER_DICT[nid]
return render(request, "detail.html", {"detail_info": detail_info})
1.4 为路由映射名称
from django.conf.urls import url,include
from django.contrib import admin
from cmdb import views
urlpatterns = [
url(r‘^asdfasdfasdf/‘, views.index, name=‘i1‘), #第一种方式i1
url(r‘^yug/(\d+)/(\d+)/‘, views.index, name=‘i2‘), #第二种方式i2
url(r‘^buy/(?P<pid>\d+)/(?P<nid>\d+)/‘, views.index, name=‘i3‘), #第三种方式i3
]
在templates目录下的index.html
<body>
{#第一种方法i1 路径asdfasdfasdf/#}
{#<form action="{% url "i1" %}" method="post">#}
{#第二种方法i2 路径yug/1/2/#}
{#<form action="{% url "i2" 1 2 %}" method="post">#}
{#第三种方法i3 路径buy/1/9//#}
<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>
</body>
1.5 根据app对路由分类
主程序urls.py文件
from django.conf.urls import url,include
from django.contrib import admin
urlpatterns = [
url(r‘^monitor/‘, include(‘monitor.urls‘)), #调整到monitor目录中的urls.py文件
]
cmdb下的url.py文件
from django.conf.urls import url
from django.contrib import admin
from monitor import views
#
urlpatterns = [
url(r‘^login‘, views.login),
]
1.6 获取当前URL
view.py中配置
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})
在templates目录下的index.html文件
<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>
2. 视图
3. ORM操作
