cannot decorate more than one view with @inflate

[whsu00]

flask requires view names to be unique, and since the raw wrapper function is returned by inflate, using the @inflate decorator on multiple views raises an exception:

from flask import Flask
from flask_inflate import inflate

app = Flask(__name__)

@app.route('/a')
@inflate
def a():
    return 'a'

@app.route('/b')
@inflate
def b():
    return 'b'

AssertionError: View function mapping is overwriting an existing endpoint function: wrapper

one solution is to decorate the inner function with python's built-in @functools.wraps:
