I have a model named VisitorInfo in models.py which is as follows:

class VisitorInfo(models.Model):
 #To maintain clarity i am not showing all the fields.

 visitor_id = models.CharField(max_length=120)
 pages_visited = models.ManyToManyField(Page,blank=True)
 time_zone = models.CharField(max_length=120, null= True, blank=True)
 ip = models.CharField(max_length=120, null= True, blank=True)
 device_type = models.CharField(max_length=120, null=True)

Following is the view where i am using this model.

class Live_Now(LoginRequiredMixin, TemplateView):
 template_name = 'dashboard/live_now.html'

def get_context_data(self, **kwargs):
 context = super(Live_Now, self).get_context_data(**kwargs)
 search = self.request.GET.get('q')

 if search:
 if VisitorInfo.objects.filter(Q_filter).filter(active=True).count() >0:
 context['list_no'] = VisitorInfo.objects.filter(Q_filter).filter(active=True)
 else:
 context['list_no'] = "N"
 return context

What i need to do as soon as live_now.html page loads and Live_Now view runs, a new tab will open with following url.

url = 54.161.109.227:5000/visitor_id 

I know that to open a new tab i have to write down script in live_now.html which is as follows.

<script type='text/javascript>
window.open(url); // Above written url
</script>

But how do i fetch visitor_id of the visitor at runtime. Fetching visitor_id is the task fo python function and opening new tab is the function of javascript. How do i pass value of python variable in javascript program ?

For time being i am fetching visitor_id of first visitor in visitors and i have written the following function to do this.

def myfunc():
 visitors= VisitorInfo.objects.all()
 for visitor in visitors[:1]:
 visitorId = visitor.visitor_id
 return str(visitorId)

You're making this much harder than it needs to be. If you need your JS to have a particular value, then pass it there.

def get_context_data(self, **kwargs):
 ... existing code ...
 context['visitor_id'] = Visitor.objects.first().user_id
 return context

...

url = "54.161.109.227:5000/ visitor_id ";
window.open(url)

Of course you can just as easily pass the whole Visitor object to the template and do visitor.user_id , it's up to you.
