How to set cookie and render template in Django?

I want to set a cookie inside a view and then have that view render a template. As I understand it, this is the way to set a cookie:

def index(request):
    response = HttpResponse('blah')
    response.set_cookie('id', 1)
    return response

However, I want to set a cookie and then render a template, something like this:

def index(request, template):
    response_obj = HttpResponse('blah')
    response_obj.set_cookie('id', 1)
    return render_to_response(template, response_obj)   # <= Doesn't work

The template will contain links that when clicked will execute other views that check for the cookie I'm setting. What's the correct way to do what I showed in the second example above? I understand that I could create a string that contains all the HTML for my template and pass that string as the argument to HttpResponse but that seems really ugly. Isn't there a better way to do this? Thanks.

You can set cookies and render a template in these ways as shown below. *You must return the object otherwise cookies are not set to a browser different from Django sessions which can set the session id cookies to a browser without returning the object and you can see my answer explaining how to set and get cookies in Django.

render() and set_cookie():

from django.shortcuts import render

def my_view(request, template):
    response = render(request, template)
    response.set_cookie('name', 'John')
    response.cookies['age'] = 27
    return response # Must return the object

render_to_string(), HttpResponse() and set_cookie():

from django.template.loader import render_to_string
from django.http import HttpResponse

def my_view(request, template):
    rts = render_to_string(template)
    response = HttpResponse(rts)
    response.set_cookie('name', 'John')
    response.cookies['age'] = 27
    return response # Must return the object set

                response = render(request, 'admin-dashboard.html',{"email":email})
                #create cookies
                expiry_time = 60 * 60 #in seconds
                response.set_cookie("email_cookie",email,expiry_time);
                response.set_cookie("classname","The easylearn academy",expiry_time);

If you just need the cookie value to be set when rendering your template, you could try something like this :

def view(request, template):
    # Manually set the value you'll use for rendering
    # (request.COOKIES is just a dictionnary)
    request.COOKIES['key'] = 'val'
    # Render the template with the manually set value
    response = render(request, template)
    # Actually set the cookie.
    response.set_cookie('key', 'val')

    return response

The accepted answer sets the cookie before the template is rendered. This works.

response = HttpResponse()
response.set_cookie("cookie_name", "cookie_value")
response.write(template.render(context))

This is how to do it:

from django.shortcuts import render

def home(request, template):
    response = render(request, template)  # django.http.HttpResponse
    response.set_cookie(key='id', value=1)
    return response

def index(request, template):
    response = HttpResponse('blah')
    response.set_cookie('id', 1)
    id = request.COOKIES.get('id')
    return render_to_response(template,{'cookie_id':id})
