flask-login can not be used in Blueprint object?
It is also possible to LoginManager.setup_app() on Blueprint's registration:
admin = Blueprint('admin', __name__)login_manager = LoginManager()@admin.record_oncedef on_load(state): login_manager.init_app(state.app)on_load will be run when the Blueprint is first registered to the app.
That's why it called setup_app
Just move initialization to your run.py and pass app as parameterAnd login itself can stay inside admin blueprint
