python - 我的 formencode.variabledecode 返回一个空列表 - Pylons

Question

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 form_result

我想要得到的是返回的列表。像这样的东西:

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

我做错了什么？

Answer 1

您的示例不完整，但您必须先解码变量:

from formencode import variabledecode

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

如果您想要废话，您还应该更改该行:

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

至:

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