Question

所以我有以下工作代码，我过去几个月一直在使用

class UserSchema(colander.MappingSchema):
    dob = colander.SchemaNode(
            colander.Date(),
            title='Date of birth:')

 if 'submit' in request.POST:

    controls = request.POST.items()
    try:
        appstruct = myform.validate(controls)
    except ValidationFailure, e:
        return {'form':e.render(), 'values': False}

现在这是一个基本的日期选择器，如下所示：

但突然间，当使用这个小部件时，我收到了错误：

至少将当前表单控件转储到日志记录并在此处发布。试着变得更加冗长清楚你的代码示例，不要混淆漏勺模式代码和金字塔视图代码。

 if 'submit' in request.POST:

    controls = request.POST.items()
    try:
        appstruct = myform.validate(controls)
    except ValidationFailure, e:
        log.debug('form validation fails for %r' % controls)
        return {'form':e.render(), 'values': False}

奇怪的变形/漏勺行为＆＃34;字符串索引必须是整数＆＃34;
