program fall on FlaskInjector(app=app, injector=injector)

[mrKAndrew]

I have Flask app with flask-injector with creat function.

def create_app(testing: bool = False) -> Flask: app = Flask(__name__) config_app(app, testing) db.init_app(app) migrate.init_app(app, db) router.init_app(app) CORS(app) # Setup injector injector = Injector([AppModule(app.config)]) FlaskInjector(app=app, injector=injector) return app
when i start app (flask run) i get error:

This typically means that you attempted to use functionality that needed
an active HTTP request. Consult the documentation on testing for
information about how to avoid this problem.

what did i wrong?

Something similar also happens for me with Flask==2.0.0.

[clementta]

This commit fixes it: b57e5e0

It is fixed in master branch but not released yet.
Solution would be to have a 0.12.4 release

[ansonnn07]

I’m having the same issue when using FlaskInjector. Had to downgrade both Flask and Werkzeug versions to below 2.0 to make it work.

[evgenyk-storexray]

@clementta-tagheuer, huge thanks for fixing the issue.
Do you know when 0.12.4 will be released ?
It is a real blocker, since I'm Flask 2.x.x for async support and Injector doesn't supports new Flask.

[clementta]

Hi @evgenyk-storexray, unfortunately I can't do releases for this project.
We need either @alecthomas or @jstasiak to do it.

Meanwhile, I suggest you force Flask to 1.1.4 in your project, or drop Flask Injector dependance.

[EvgenyKhaliper]

Thanks, @clementta-tagheuer hopefully, one of them will be here soon. lol

[benomalley25]

@alecthomas , @jstasiak any updates on when the above bugfix could be released?

[heydev]

Same, blocker for us since we won't downgrade Flask.

[jstasiak]

This project doesn't work with Flask 2 yet. I'm afraid there'll be no releases until #66 is resolved (and I have no time to work on it).

[mic4ael]

Any update on this?

[remirab]

@alecthomas , @jstasiak please release the latest version. It's a real blocker.

[jstasiak]

I don't think there's anything to release, but please show a minimal, complete piece of code (together with the versions of Python, Flask, Werkzeug and any other relevant packages) that fails on the last released version but works with the master branch and I'll reconsider.

Hi! I just hit this issue, but only on Windows. It works fine on macOS for me. Here is a very small example that reproduces the issue on my end:

requirements.txt:

flask==2.0.0
flask-injector==0.12.3

main.py

from flask import Flask
from flask_injector import FlaskInjector
from injector import singleton


class Dep:
    def __init__(self):
        pass


class Server:
    def __init__(self):
        app = Flask(__name__)

        @app.route('/')
        def index():
            return 'hello, world'

        def configure(binder):
            binder.bind(Dep, to=Dep(), scope=singleton)

        FlaskInjector(app=app, modules=[configure])

        self.app = app


if __name__ == '__main__':
    server = Server()
    server.app.run()

[jstasiak]

@nielspedersen Thanks, two bits missing still: what Python and Werkzeug versions?
