What is the best way to display specific items in a bootstrap navbar by utilizing cookies with Python?

Below is the structure of my bootstrap navbar which is present in my base template:

<ul class="nav navbar-nav">
    <li><a href="/">Home</a></li>
    <li><a href="/about">About</a></li>
    <li><a href="/post">New Post</a></li>   
    <li><a href="/login">Login</a></li>
    <li><a href="/logout">Logout</a></li>
    <li><a href="/register">Register</a></li>
</ul>

I am looking for a way to toggle the visibility of certain list items on the navbar based on whether the user is signed in or not. Specifically, I want to hide the New Post and Logout items when the user is not signed in, and hide the Login and Register items when he is signed in. Any suggestions on how to achieve this functionality?

To provide a bit more context, my tech stack includes Python 2.7 with Jinja2 for templating and user authentication is managed through cookies.

Answer №1

Here is an example of how you could structure your navigation using conditional logic:

{% if user %}
    <ul class="nav navbar-nav">
        <li><a href="/">Home</a></li>
        <li><a href="/about">About</a></li>
        <li><a href="/post">New Post</a></li>  
        <li><a href="/logout">Logout</a></li>
    </ul>
{% elif not user %}
    <ul class="nav navbar-nav">
        <li><a href="/">Home</a></li>
        <li><a href="/about">About</a></li> 
        <li><a href="/login">Login</a></li>
        <li><a href="/register">Register</a></li>
    </ul>
{% endif %}

In this scenario, the display will change based on whether the variable user is set or not. This can be determined by checking for a specific cookie in your view before passing the information to the template.
