Django override default form error messages

Question

How can I overwrite the default form error messages (for example: need them in other language) for the all apps in my project (or at least for 1 app)

Thanks!

Hmm, seems there is no easy workaround for the problem.

Wile skimming through the django code, I've found that default error messages are hard-coded into each form field class, for ex:

class CharField(Field):
    default_error_messages = {
        'max_length': _(u'Ensure this value has at most %(max)d characters (it has %(length)d).'),
        'min_length': _(u'Ensure this value has at least %(min)d characters (it has %(length)d).'),
    }

And the easiest way is to use the error_messages argument, so I had to write the wrapper function:

def DZForm(name, args = {}):
    error_messages = {
        'required': u'required',
        'invalid': u'invalid',
    }
    if 'error_messages' in args.keys():
        args['error_messages'] = error_messages.update(args['error_messages'])
    else:
        args['error_messages'] = error_messages
    return getattr(forms, name)(**args)

If smdb knows more elegent way of doing this would really appreaciate to see it :)

Thanks!
