Using flask url_for

I find myself using the url_for function a lot.

However, I only just released you can pass any params you want to it and these will be made available as URL params to the flask route.

For example,

<a href="{{ url_for('', expected=param, another=other, param="I want")}}>A link</a>

Then I can access them in the route using request.args. For example

def route_func(expected)
    arg1 = request.args.get('another')

This works becuase any arguments that don't match a route parameter will be added as a query string. This means if using url_for in your python code then you can unpack a dict to add a host of params to the query string.

url_for('', **extra_args)
