目的： 打开http://127.0.0.1:8000/home 点击查看详情转到 http://127.0.0.1:8000/detail-1-1.html实现查看具体信息
一，利用url路由系统的正则表达式传参数
url(r'^detail-(?P<uid>d+)-(?P<nid>d+).html',views.detail),
def detail(request,uid,nid):
return
urls:
from django.contrib import admin
from django.urls import path
from cmbd import views
from django.conf.urls import url
urlpatterns = [
path('admin/', admin.site.urls),
path('home/', views.home),
path('home', views.home),
url(r'^detail-(?P<uid>d+)-(?P<nid>d+).html',views.detail),
]
views:
from django.shortcuts import render,redirect
user_dict = {
'1':{'name':'hrg','email':'hrg@163.com','pwd':'123'},
'2':{'name':'eric','email':'hrg@163.com','pwd':'111'},
'3':{'name':'hhh','email':'hrg@163.com','pwd':'222'},
'4':{'name':'kkk','email':'hrg@163.com','pwd':'123'},
}
def home(request):
return render(request,'home.html',{'user_dict':user_dict,})
def detail(request,uid,nid):
detail_dict = user_dict[uid]
print(detail_dict)
return render(request,'detail.html',{'detail_dict':detail_dict,})
templates:
home.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<ul>
{% for k,v in user_dict.items %}
<li>
<span>id:{{ k }}姓名：{{ v.name }}</span>
<a href="/detail-{{ k }}-1.html">查看详情</a>
</li>
{% endfor %}
</ul>
</body>
</html>
detail.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>用户详情：</h1>
<ul>
{% for k,v in detail_dict.items %}
<li>{{ k }}:{{ v }}</li>
{% endfor %}
</ul>
</body>
</html>
二，利用URL地址栏？功能传参数
/detail?uid=1&pid=2
urls:
from django.contrib import admin
from django.urls import path
from cmbd import views
from django.conf.urls import url
urlpatterns = [
path('admin/', admin.site.urls),
path('home/', views.home),
path('home', views.home),
path('detail',views.detail),
]
views:
from django.shortcuts import render,redirect
user_dict = {
'1':{'name':'hrg','email':'hrg@163.com','pwd':'123'},
'2':{'name':'eric','email':'hrg@163.com','pwd':'111'},
'3':{'name':'hhh','email':'hrg@163.com','pwd':'222'},
'4':{'name':'kkk','email':'hrg@163.com','pwd':'123'},
}
def home(request):
return render(request,'home.html',{'user_dict':user_dict,})
def detail(request):
uid = request.GET.get('uid') #获取home.html中/detail?uid={{ k }}传来的值
detail_dict = user_dict[uid]
print(detail_dict)
return render(request,'detail.html',{'detail_dict':detail_dict,})
templates:
home.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<ul>
{% for k,v in user_dict.items %}
<li>
<span>id:{{ k }}姓名：{{ v.name }}</span>
<a href="/detail?uid={{ k }}">查看详情</a>
</li>
{% endfor %}
</ul>
</body>
</html>
detail.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>用户详情：</h1>
<ul>
{% for k,v in detail_dict.items %}
<li>{{ k }}:{{ v }}</li>
{% endfor %}
</ul>
</body>
</html>
