通用视图-分开处理GET、POST请求

1.编辑urls.py:

    url(r'^vmmgmt-vms/$', views.vmmgmt,{'model':models.hvvms,'GET': views.vmmgmt_get_view,'POST': views.vmmgmt_post_view},name='vmmgmt-vms'), #vmmgmt view接收model,GET,POST参数
url(r'^vmmgmt-hv/$', views.vmmgmt,{'model':models.hvsrvs,'GET': views.vmmgmt_get_view,'POST': views.vmmgmt_post_view},name='vmmgmt-hv'),
url(r'^vmmgmt-vhd/$', views.vmmgmt,{'model':models.hvvhds,'GET': views.vmmgmt_get_view,'POST': views.vmmgmt_post_view},name='vmmgmt-vhd'),

2.编辑views.py:

#split get and post requests.
def vmmgmt(request,*args,**kwargs): #从url接收参数,用于区分GET、POST请求
vmmgmt_get_view = kwargs.pop('GET', None) #return None if GET not exists.
vmmgmt_post_view = kwargs.pop('POST', None)
model = kwargs.pop('model', None) #获取当前model
if request.method == 'GET' and vmmgmt_get_view is not None: #GET请求返回到vmmgmt_get_view()函数进行处理
return vmmgmt_get_view(request, model) #将model传递到get view
elif request.method == 'POST' and vmmgmt_post_view is not None:
return vmmgmt_post_view(request, model)
#return vmmgmt_post_view(request, *args, **kwargs)
raise Http404 #handle get request.
def vmmgmt_get_view(request,model):
obj_list = model.objects.all() #从url中的 model 参数接收到具体的model类。模板中要使用 obj_list 变量做for循环
counts = model.objects.count()
assert request.method == 'GET'
if 'q-hv' in request.GET:
qdata = request.GET['q-hv']
if qdata is not None:
obj_list = model.objects.filter(serverip__icontains=qdata)
counts = len(obj_list) if 'q-vms' in request.GET: #Query vm infors.
qdata = request.GET['q-vms']
if qdata is not None:
obj_list = model.objects.filter(Name__icontains=qdata)
print obj_list
counts = len(obj_list) context={'obj_list':obj_list,'counts':counts}
template_name = 'sinfors/vmmgmt_%s.html' % model.__name__.lower() # 每个Python的类都有一个 __name__ 属性返回类名。 这特性在当我们直到运行时刻才知道对象类型的这种情况下很有用。 比如, hvvms 类的 __name__ 就是字符串 'hvvms' 。
#return render_to_response(template_name,context) #无法接收csrfmiddretoken参数
return render(request,template_name,context) #handle post request.
def vmmgmt_post_view(request,model):
assert request.method == 'POST'
if request.POST['posttype'].strip() == 'hvservers_update_create': #update hv servers infors.
sdict = {}
sdict['serverip'] = request.POST['serverip'].strip()
sdict['servername'] = request.POST['servername'].strip()
model.objects.update_or_create(serverip=sdict['serverip'],defaults=sdict)
return HttpResponse(json.dumps({'sts':"修改成功"})) if request.POST['posttype'].strip() == 'vhds_update_create': #update vhd servers infors.
sdict = {}
sdict['vhdname'] = request.POST['vhdname'].strip()
sdict['vhdpath'] = request.POST['vhdpath'].strip()
model.objects.update_or_create(vhdname=sdict['vhdname'],defaults=sdict)
return HttpResponse(json.dumps({'sts':"修改成功"})) if request.POST['posttype'].strip() == 'del': #delete infors.
datas_del = request.POST.getlist('datas_del')
for i in datas_del:
item = model.objects.get(pk=i)
time.sleep(0.1)
item.delete()
return HttpResponse(json.dumps({'sts':"删除成功"})) context={'obj_list':obj_list,'counts':counts}
template_name = 'sinfors/vmmgmt_%s.html' % model.__name__.lower() # 每个Python的类都有一个 __name__ 属性返回类名。 这特性在当我们直到运行时刻才知道对象类型的这种情况下很有用。 比如, hvvms 类的 __name__ 就是字符串 'hvvms' 。
#return render_to_response(template_name,context) #无法接收csrfmiddretoken参数
return render(request,template_name,context)
