RQ-Dashboard can no longer be integrated with Flask 2.3+ as a blueprint

[born2discover]

Hello,

app.before_first_request and blueprint.before_first_request have been deprecated in Flask 2.2.0 (pallets/flask#4605) and completely removed in version 2.3.0.

Therefore it is no longer possible for projects using Flask 2.3.0 to integrate rq-dashboard directly as an application blueprint. An attempt to do so will produce an AttributeError: 'Blueprint' object has no attribute 'before_app_first_request'.

Our team has run into the same issue.

Any workarounds or alternatives someone have for this issue?

@mbhagdev I saw that you seem to have a fork of RQ Dashboard – does your fork fix this issue?

Yes, I removed the annotation in question and called it in when loading flask app
I have a PR to be merged back in #419
For usage in another flask app make sure to call that method now since its not automatically called like below using your flask app

app.config.setdefault('RQ_DASHBOARD_REDIS_URL', redis_url)
rq_dashboard.web.setup_rq_connection(app)

My fork is also published on pypi as rq-dashboard-compatible
pip install rq-dashboard-compatible

Thanks @mbhagdev, confirmed that your fork works with flask==2.3.2!

Our team has created a separate fork internally that branches off of the 0.6.1 tag with the same changes, since your fork is based on master which has a completely different and new (?) UI.

@AriefBadal23 did you compile it from the source or did you use the releases? we did not update the releases, just the source

Oh I checked the released version, I will try the source then.

[cjlapao]

@AriefBadal23 yes, the version has not been updated yet. we are working on automating this, will let you know once that automation if finalized, for now please use the source code

[mattiadri]

This worked for me

pip install rq-dashboard-compatible

@AriefBadal23 we have now the PyPi package updated, so you should be all fine. Update to the latest 0.6.6
