How to call a verification function from views to templates?

Question

I have a function to check if the user is a staff:

class VerificateUser():
    def allowed_user(request):
        if request.user.is_staff:
            return True

In my template, I’m going to show this section only for staff users, but this is not working.

{% url if not allowed_user %}
<h1>
    Welcome to the show
</h1>

If do something like it, works:

```html
{% if not request.user.is_staff %}
<h1>
    Welcome to the show
</h1>

But I need to use a view function to clean my code because I’m probably going to add more conditionals.

Answer 1

You can do this sort of thing in many ways, but simply you can do by the following way-

{% if request.user.is_authenticated %}
    <p>Welcome,{{request.user.first_name}} </p>          
{% endif %}

request object is by default available in all of your Django templates context.

Since you are using a class-based view then I would suggest updating the context dictionary which you could use in the html template to determine whether the user is allowed or not. For example, Within the views.py.

class VerificateUser():
    # Update the context
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)

        # Call the allowed_user() and return whatever value, passing that value it to the context variable
        context['allowed_user'] = self.allowed_user()

    return context

    # Checking if the user is allowed here
    def allowed_user():
        if self.request.user.is_staff:
            return True

        return False

Now within the html file, you can reference that allowed_user from the context variable.

{% if allowed_user %}
    <h1>Hi, you are allowed to see here...</h1>
{% endif %}

That should do the trick.
