The goforms library is a proof-of-concept for a data validation, cleaning and error collecting library for golang, in similar style to Django's django.forms library.

While thinking about writing web application in go, I wanted to be able to encapsulate the data validation and cleaning for http request handlers, so that the handler itself could be thin:

{{{ func my_post_handler(w http.ResponseWriter, r *http.Request){ myForm := MyCustomForm() myForm.SetFormData(r.Form)

if myForm.IsValid(){
    // Do something with myForm.CleanedData, which is the request's form
    // data after being cleaned to the correct types etc.
} else {
    // Re-render a template, passing in egForm.Errors which is a map
    // of errors for each field on the form.
}

}}}

As there didn't seem to be anything similar available for golang, I created goforms as a proof-of-concept (see http://goo.gl/pFh6I for golang-nuts post).
