How to make a view counting system?

Question

Django

Hello everyone
Task: the site has a lot (several thousand products), you need to first develop a system for recording views - i.e. which product is viewed more, which less, etc. This will then be used for various recommendation systems.
What is the best way to count views?

• +1 every time the page is rendered
  
• +1 every time after full page load via ajax request
  

How to protect yourself from bots, spiders and other trash that can wind up the counter for nothing?

Answer 1

Make a url counter that is inserted into the page as empty <script src="/mycounter">
. Firstly, bots usually don't load scripts, and secondly, it's very simple. And thirdly, most likely the browser has already loaded the page.
Don't forget to give a non-cached header, otherwise the browser will load your empty counter once and won't load it again.

Answer 2

Good afternoon, we have implemented this field in the product model: In the product view class (we have DetailView), the get_object method is overridden:

def get_object(self, queryset=None):
        self.object = super(DetailViewPageView, self).get_object()
        self.object.show_count += 1
        self.object.save()
        return self.object

can also be applied if the function is simply used when calling the object +1 and save()
