Add param **values like Flask's url_for to fields.Url

[felipemfp]

Hey,

I've worked with this awesome framework, but I cannot create a simple output like:

"log": {
  "_links": {
    "self": "/api/v1/company/5/log/2016/6/5"
  }
}

... because my object Log does not have attributes like year, month and day.

Since url_for from Flask accepts **values, why not accept it on output fields? So I just add it.

Now I can:

log_fields = {
  '_links': {'self': fields.Url(year=2016, month=6, day=5)}
}

Or:

log_fields = {
  '_links': {'self': fields.Url(year=lambda x: x.custom_date.year(), month=lambda x: x.custom_date.month(), day=lambda x: x.custom_date.day())}
}

Regards 😃

Is this project still active?

No, I don't think it is. See issue #883
