实现一个计数器，用django计数请求

本文介绍了实现一个计数器，用django计数请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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
