My formencode.variabledecode is returning an empty list - Pylons

HTML:

<input type="text" name="blah-0" value="test" />
<input type="text" name="blah-1" value="another test" />

Controller:

class myvalidator(formencode.Schema):

    allow_extra_fields  = True
    filter_extra_fields = True

    test = formencode.ForEach(formencode.validators.String())

def form_posted(self):
     form_result = myvalidator().to_python(request.params)

     print fo开发者_StackOverflowrm_result

What I'm trying to get is a list returned. Something like:

> print form_result['blah']
['test', 'another test']

What am I doing wrong?

Your example is incomplete but you must decode your variables before:

from formencode import variabledecode

def form_posted(self):
     decoded = variabledecode.variable_decode(request.params)
     form_result = myvalidator().to_python(decoded)
     print form_result

You also should change that line if you want blah:

test = formencode.ForEach(formencode.validators.String())

to:

blah = formencode.ForEach(formencode.validators.String())
