Using flask_login session with jinja2 templates

Question

I have simple jinja2 template with registration/login links, I should hide them when user logged in, I also use flask_login module for this stuff.

Question is: How should I identify is user logged in in jinja2 templates?

Solution

Flask-Login adds the current_user variable to your templates:

{% if current_user.is_authenticated %}
    ...
{% else %}
    ...
{% endif %}

They mention this briefly in the documentation.

Flask-login docs do specify that You can then access the logged-in user with the current_user proxy, which is available in every template

Now is {% if current_user.is_authenticated %}

Note that when using {{ current_user.is_authenticated }} in javascript, that the value returned is not understood and must be put in a a string such as "{{ current_user.is_authenticated }}". Came across this when validating onclick ajax requests for logged in users.
