Flask-Discussion

Flask-Discussion is an extension for Flask that adds support for several discussion/comment systems to your application.

Supported comment systems:

• Disqus
• Isso
• Remark42

Quickstart

First install the extension:

pip install Flask-Discussion

And then initialize it in your application:

from flask import Flask
from flask_discussion import Discussion

discussion = Discussion()

def init_app():
    app = Flask(__name__)

    # Set config values
    # .....

    discussion.init_app(app)

This will register the extension templates (which contain the macros for each comment system) with your application, making them available in your own templates.

If you want to be able to swap comment systems through the configuration of your application, you may use the macro defined in flask_discussion/helper.html:

{% import "flask_discussion/helper.html" as discussion %}

<html>
    <body>
        {{ discussion.render_comments(title="Page title", identifier="my-page", url="http://mypage.com") }}
    </body>
</html>

Note that the macro receives any keyword argument and will relay the appropriate information to the corresponding system-specific macro (i.e. each comment system may use only specific information, therefore you should provide all possible values for all comment systems).

However, if you only want to use a specific comment system, you may import its macros directly. For instance, for Disqus:

{% import "flask_discussion/disqus.html" as disqus %}

<html>
    <body>
        {{ disqus.render_comments(identifier="my-page", url="http://mypage.com", title="Page title") }}
    </body>
</html>
