Question

I'm trying to build a channel. I don't want the other users have an access to the detail views. The thing is I can make it accessible to one but I don't know how to make it accessible for both consumer & seller?

class Group(models.Model):
    consumer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="", blank=True, null=True)
    name = models.CharField(max_length=10)
    seller = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="")
    ...

    def __str__(self):
        return self.name

#Detail channel
@method_decorator(login_required(login_url='/cooker/login'),name="dispatch")
class CheckoutDetail(generic.DetailView):
    ...
    
    def get(self,request,*args,**kwargs):
        self.object = self.get_object()
        if self.object.consumer or self.object.seller != request.user: #it's redirect me to home page
            return HttpResponseRedirect('/')    
        
        return super(CheckoutDetail, self).get(request,*args,**kwargs)

Answer 1

The correct logic would be

if not (request.user == self.object.consumer or request.user == self.object.seller):
    return redirect(...)

but I'd refactor that logic into a function in the object , eg

def has_access(self, user):
    return (self.consumer == user or self.seller == user)

and then call it, eg

if not self.object.has_access(user=request.user):
    # ...

If I correctly understand you, you must change this line like this:

    if self.object.consumer != request.user and self.object.seller != request.user:
        return HttpResponseRedirect('/')
