Question

Here is the code in my base.html header

    <script>
        var auth_status = "{{ user.is_authenticated }}"
    </script>

    {% block scripts %}  {% endblock %}

The rest of the scripts in my site are in the block scripts.

In a child template (within the script block and within script tags) I have this code,

         if (auth_status) {
          //something
         }

The error at hand is auth_status is always True, when it should be on and off depending on if the user is logged in. Request_context is being passed to the template so that should not be the error.

Thanks

For what I see your auth_status variable seems to be a string, not a boolean. A variable with a non-empty string on javascript will evaluate to true on an if clause.

Anyhow, something like

<script>
    var auth_status = {{ user.is_authenticated }};
</script>

will not work because that will generate this HTML:

<script>
    var auth_status = True;
</script>

As Python’s True boolean is uppercased.

This should do the translation from Python to Javascript:

<script>
    var auth_status = {{ user.is_authenticated|yesno:"true,false" }};
</script>
