Check if a user has a subscription with dj-stripe in Django templates

Question

I'd like to have a button in many different Django templates that encourages users to subscribe to one of two dj-stripe paid plans, but I don't want to show the button to users who have already subscribed to either plan.

I know I can use {% if user.is_authenticated %} in templates. I haven't been able to find something similar for checking if a user is subscribed to a dj-stripe plan. Is there something, and if so, what is it? If not, how can I handle this without a lot of repetition?

maybe you could add an attribute `is_subscribed` to your user model? — nnaelle, May 25 '15 at 21:12

It turns out that there is a dj-stripe solution to this already (that I hadn't found in my Google searches).

I just added this to my extended user model:

def __str__(self):
    return self.username

def __unicode__(self):
    return self.username

@cached_property
    def has_active_subscription(self):
        """Checks if a user has an active subscription."""
        return subscriber_has_active_subscription(self)

And then added this to my template:

{% if request.user.has_active_subscription %}
    <a href="/payments/history/">Subscription History</a>
{% else %} 
    <a href="/payments/subscribe/">Upgrade to Premium Content!</a>
{% endif %}

Please note: if you're logged in as staff or as a superuser, you will automatically be marked as having an active subscription. – Michelle Glauser Jul 07 '15 at 05:09
What if I have multiple plans, like Premium, Enterprise and Starter? I need to check what type of subscription the user has – martin Jan 12 '21 at 13:29

I agree with @nnaelle that adding an is_subscribed attribute to your user model is a good option for ensuring that the subscribe button isn't shown to your users that are already subscribed. Adding this attribute means that, if you haven't already, you'll need to extend the user model in your models.py to keep track of whether they are subscribed. This looks something like this (as in the Django docs):

from django.contrib.auth.models import User

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    is_subscribed = models.BooleanField(default=False)

The new user model can then be accessed by, say, the views in views.py:

from my_app.models import UserProfile

def index(request):
    user = request.user
    userprofile = UserProfile.objects.get(user=user)
    ...

You can (and might want to) avoid having to access the user profile that way, however, by making your new user model the default for your app under settings.py as described in the docs for substituting custom user models. Then after passing in the new user model to the view, you can do a check for subscription status using {% if not userprofile.is_subscribed %} and only show the subscription button for those who aren't subscribed:

{% if not userprofile.is_subscribed %}
    <div ...></div>
{% endif %}

Feel free to give me your feedback!
