实现一个计数器,用django计数请求 [英] implementing a counter that counts requests with django
问题描述
我只是尝试使用Django,
我如何实现一个计数器来存储数据库中服务的请求计数?
I'm just trying with Django, how can i implement a counter that stores the count of requests served on the database?
我想计算GET请求,我该怎么办?
I want to count the GET requests, what should I do make it work?
我的模板,
<form action="/submit/" method="GET">
<input type="text" name="q">
<input type="submit" value="Submit">
</form>
我的观点
def result(request):
name = request.GET['q']
message = 'your name is %r ' % name
return render(request, 'result.html', {'message': message})
我想计算次数我按提交按钮。我应该启动一个新的应用程序 counter
还是存在其他实现计数器的方法?
I want to count the number of times i press the submit button. should I start a new app counter
or there exist some other way to implement a counter?
推荐答案
这可能有点混乱,但是您应该从会话中获得基本概念,而不是get方法
model / .py吸引朋友的模型
This might be a little messed up but you should get the basic concept you get it from the session not the get methods model/.py the model that tracts your friend
friend = models.ForeignKey("self", related_name="referral", null=True, blank=True)
view.py这是您计数的朋友
view.py this is how many friends you have counted
cool_obj = cool.objects.get(ref_id=ref_id)
obj = cool.objects.filter(friend=cool_obj)
count = cool_obj.referral.all().count()
这是如何通过中间件获取内容的方法
this how you get your stuff through the middleware
def home(request):
try:
cool_id = request.session['cool_id_ref']
obj = cool.objects.get(id=cool_id)
except:
obj = None
form = CoolJoin(request.POST or None)
if form.is_valid():
new_cool = form.save(commit=False)
email = form.cleaned_data['email']
new_cools, created = cool.objects.get_or_create(email=email)
if created:
new_cools.ref_id = get_ref_id()
if not obj == None:
new_cools.friend = obj
new_cools.ip_adress = get_ip(request)
new_cools.save()
return HttpResponseRedirect("/%s" %(new_cools.ref_id))
context = {"form": form}
template = "home.html"
return render(request, template, context)
中间件/
class ReferMiddleware():
def process_request(self, request):
ref_id = request.GET.get("ref")
try:
obj = cool.objects.get(ref_id = ref_id)
except:
obj = None
if obj:
request.session['cool_id_ref'] = obj.id
