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?

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](https://flask-login.readthedocs.org/en/latest/) do specify that `You can then access the logged-in user with the current_user proxy, which is available in every template` – Devi Jun 18 '15 at 09:13

Now is {% if current_user.is_authenticated %} – anvd Oct 01 '15 at 22:55

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. – deesolie Oct 04 '20 at 04:24
