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)

    def depart_delete(request):

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

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

    ret.delete()

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

    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
