Skeeve has asked for the wisdom of the Perl Monks concerning the following question:

Sorry for the title... I couldn't think of a better one.

I'm writing a Dancer application and was wondering whether or not there is a way to change the data the user supplied.

I have, for example, a date input field where the user is expected to enter data in ISO format. But I could be "forgiving" and accept something like "2014-1-3" and rewrite it to "2014-01-03".

But I couldn't find a way yet to assign a value to my param('dateinput'). Is there a way at all?

+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e

    There's Dancer::Plugin::Params::Normization. Perhaps a bit heavy (you'll have to write a custom class), but the overview indicates this functionality is there for the exact reason you've posted.

      Sorry, but no. I read the description as normalization of the parameter names. So whether someone supplied "NAME=John" or "name=John" to the path, the result will be that the parameter name becomes "name" when "lowercase is set as normalization.

      +.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e

        Yes, that is the example, but read a bit further on the part about the custom class... 
        normalize($hashref)

Receives a hashref that contains the parameters keys/value. It should 
+return a hashref (it can be the same), containing modified parameters
+.

        Sounds like you can modify values as well, since you're returning a hashref with both keys and values.
