How can I choose which parameter to pass to a multidecorated route in Flask?

Question

I am using the following code:

@api.route('/akilo/<a>/<b>/')
@api.route('/akilo/<c>/')
class Akilo(Resource):
    def get(self, a, b, c):
        if a and b:
            return a + b
        else:
            return c

to get different responses from the same resource, depending on which parameters I am using

When I make a request with:

/select/akilo/bom/dia/

I get the following error:

TypeError: get() takes exactly 4 arguments (3 given)

Could you help me?

You either need to change the signature of get to make a, b, and c optional.

def get(a=None, b=None, c=None):

Or you need to provide default values for the unused ones in your routes.

@api.route('/akilo/<a>/<b>/', defaults={'c': None})
@api.route('/akilo/<c>/', defaults={'a': None, 'b': None}) t
