Blueprint Support

[Artucuno]

Hey, I need to use Flask-Discord in a blueprint but I am not sure if that is possible.

I get the error AttributeError: 'Flask' object has no attribute 'discord' and I think its because it uses current_app instead of the blueprint itself.

Thanks

Hello, I had the same problem with quart_discord.
All you need to do is move

discord = DiscordOAuth2Session(app)

to your main file, and then import discord from main in your blueprint file.
Also to prevent circular imports remember to wrap import of blueprint and app.run() in if statement, something like that

if __name__ == "__main__":
    from blueprints.api import api
    from blueprints.dashboard import dashboard

    app.register_blueprint(api)
    app.register_blueprint(dashboard)


    app.run(host="localhost", port=5000, debug=True)

For me it works perfectly

Your blueprint should look like that

...
from flask.blueprints import Blueprint
from main import app, discord

dashboard = Blueprint('dashboard', __name__, url_prefix='/dashboard', template_folder="../templates/dashboard/")
...

And your main

app = Flask(__name__)

...

discord = DiscordOAuth2Session(app)

if __name__ == "__main__":
    from blueprints.api import api
    from blueprints.dashboard import dashboard

    app.register_blueprint(api)
    app.register_blueprint(dashboard)


    app.run(host="localhost", port=5000, debug=True)

Hey, thanks for your reply. I fixed the issue in the end by just using oauthlib and doing it from scratch just because for my case, I can't have discord imported in the main file.

Hi, @Artucuno. I'm Dosu, and I'm helping the Flask-Discord team manage their backlog. I'm marking this issue as stale.

Issue Summary:

• You reported an AttributeError when using Flask-Discord within a Flask blueprint.
• You suspected the issue was due to the use of current_app instead of the blueprint context.
• User xybl3 suggested moving DiscordOAuth2Session initialization to the main file to avoid circular imports.
• You resolved the issue independently by using oauthlib to implement the functionality from scratch.

Next Steps:

• Is this issue still relevant to the latest version of the Flask-Discord repository? If so, please comment to keep the discussion open.
• Otherwise, this issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!
