I use FlaskInjector (0.14.0) and Flask==2.3.2
And when I do this setup in my app.py:
app = create_app()
FlaskInjector(app=app, modules=[configure])
app.run(port=8000, debug=app.config["DEVELOPMENT"])
I will get this error:
Traceback (most recent call last):
File "Flask\venv\lib\site-packages\flask_injector\__init__.py", line 101, in wrap_class_based_view
class_kwargs = fun_closure['class_kwargs']
KeyError: 'class_kwargs'
During handling of the above exception, another exception occurred:

KeyError: 'self'
But I don´t get why. This is how I created a configure method to register all my bindings that should be available inside my methods views (for API).
This is my "binding" method called from the app.py
def configure(binder):
binder.bind(HttpClient,to=HttpClient)
HttpClient is only demo test class, for testing my dependency injection if I can touch it in my views. I tried also to bind this class without inheriting from "Module"
from injector import Module
class HttpClient(Module):
def test_method(self):
print("haha iam test method")
Even If I don´t use any @inject for my class based views, I am not able to build the app itself. I followed the documentation for FlaskInjector.
As I mentioned it is even problem to build the flask app with this setup.
My goal was to create this sort of API endpoint:
from flask.views import MethodView
class IndexPageAPI(MethodView):
"""Servers basic statistics to the user once he loads index page."""
init_every_request = False
@inject
def get(self, http_client: HttpClient):
self.http_client.test_method()
return jsonify({'data': 'Index page api call'})
But I didn´t get even to the point to try to access injected dependencies inside APi as I can´t build the app.
Does anyone see a problem, or what should be changed? Thank you very much.
