django---前段与后端相结合（增删改）

1增删改查步骤

(第一步)配置项目里的urls.py文件

from django.conf.urls import include,url

from django.contrib import admin

urlpatterns=[

url(r'^admin/', include(admin.site.urls)),-------include（）表示你接下来的路径

#url(r'^depart/',include('company.urls',namespace='company')),

url(r'^com/',include('company.urls',namespace='com')),----- 我要进入app为company里的urls

url(r'^user/',include('uuser.urls',namespace='user')),     

]

(二)接下来配置app里的urls.py文件   前面是匹配正则，后面是调用views.py文件里的方法    

from django.conf.urls import include,url

from django.contrib import admin

from . import views

urlpatterns = [

url(r'^admin/', include(admin.site.urls)),

url(r'^companyA/$',views.departall,name='departall'),

url(r'^company/add/$',views.depart_add,name='depart_add')      

url(r'^company/add_list$',views.departNewAdd,name='departNewAdd'),

url(r'^company/delete$',views.depart_delete,name='depart_delete'),

url(r'^company/update$',views.depart_update,name='depart_update'),

url(r'^company/update_handler$',views.depart_update_handler,name='depart_update_handler'),

(三)配置app里的views.py文件 （增）

#导入模块

from django.shortcuts import render

from django.http import *

from .models import *

from django.core.urlresolvers import reverse

#全部信息

def departall(request):

bookinfo_list =depart.objects.all()

context={

'departName':bookinfo_list,

'titlt':'这是部门名'

}

return render(request=request,template_name='companyall/departall.html',context=context)

#显示一个信息

def departMobanOne(request,pk):

        bookinfo_list =depart.objects.get(pk=pk)

        context={

                'departName':bookinfo_list,

                'titlt':'这是部门名'

        }

        return render(request=request,template_name='companyall/depart_info.html',context=context)

def depart_add(request):

return render(request=request,template_name='companyall/depart_add.html',context=None)---渲染模板

#增加内容

def departNewAdd(request):

#处理新增

infos=request.POST   ------要与htm里form表单的方法相一致

depart1=infos.get('btitle')   

#包装对象

depart2=depart()

depart2.dname=depart1

#增加对象

depart2.save()

#return HttpResponse('ok')  --------转发

#return HttpResponseRedirect()

return HttpResponseRedirect(reverse('com:departall'))-------------重定向

#增加成功之后的页面

def departAddO(request):

return HttpResponse('ok')

（四）--创建一个与与app同级的templase文件

        里面尽量在创建一个与app同名的文件夹，在他下面在创建你所需的html文件（供views.py文件使用）

                                                                                      （depart_add.html）

删

def depart_delete(request):

pk=request.GET.get('pk')

ret=depart.objects.filter(pk=pk)

ret.delete()

return HttpResponseRedirect(reverse('com:departall'))

改

def depart_update(request):

pk=request.GET.get('pk')

depart1=depart.objects.get(pk=pk)

context={

'depart1':depart1

}

return render(request=request,template_name='companyall/depart_update.html',context=context)

def depart_update_handler(request):

#获取对象

infos=request.POST

#获取属性

pk=infos.get('pk')

dname=infos.get('btitle')

#包装对象

Depart=depart.objects.filter(pk=pk)[0]

Depart.dname=dname

#修改对象

Depart.save()

#重定向

return HttpResponseRedirect(reverse('com:departall'))

                                                                                （depart_update.html）

(五)链接服务器，输入对应的url正则
