Activate FlaskLimiter on a blueprint with pluggable view
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am trying to register a blueprint in my app factory function, using a pluggable view, whilst passing in the Flask Limiter instance like so:
limiter = Limiter(app, key_func=get_remote_address)
the_api = Blueprint('the_api', __name__)
the_api.add_url_rule('/pluggable',
view_func=Pluggable.as_view('pluggable', limiter))
app.register_blueprint(the_api)
As per the limiter docs, I should be able to decorate the class as follows:
class Pluggable(MethodView):
decorators = [self.limiter.limit("1 per minute")]
def __init__ (self, limiter):
self.limiter = limiter
However I found this didn't work when limiter is passed in via the init function:
decorators = [self.limiter.limit("1 per minute")]
NameError: name 'self' is not defined
So I tried changing this to:
def __init__ (self, limiter):
self.decorators = [limiter.limit("1/minute")]
This doesn't throw an exception, but nor does it apply the limit to the endpoint (unless I've missed something).
To approach this in another manner, I could go by the Flask Docs which suggests using the following format which would be inside my app factory function:
# DOC example
view = user_required(UserAPI.as_view('users'))
app.add_url_rule('/users/', view_func=view)
However I find this doesn't work as I also need to call the method Limiter.limit.
view = Pluggable.as_view('pluggable')
limited_view = limiter(view).limit('1 per minute')
the_api.add_url_rule('/pluggable', view_func=limited_view)
which generates the error:
limited = limiter(view).limit('1 per minute')
TypeError: 'Limiter' object is not callable
What is the correct way to achieve this? Should I be creating the limiter within the MethodView.__init__ function for every pluggable view. This sounds in-efficient, plus I'd like to define my rate limits in or around the add_url_rule function.
