如何让 Pylons formencode 验证器忽略某些字段
我有一个表单，其中有一些输入文本框和一些选择框。我的验证在文本框上运行得很好。我不在乎是否有任何选择框保留默认值，但每次我提交表单时，它都会进入塔架错误页面，显示“无效：请输入...的值”，但我不希望这样发生。
这是我的验证器函数：
class Registration(formencode.Schema):
allow_extra_fields=True
first_name = formencode.validators.String(strip=True, not_empty=True)
last_name = formencode.validators.String(strip=True, not_empty=True)
address = formencode.validators.String(strip=True, not_empty=True)
phone = formencode.validators.PhoneNumber(strip=True, not_empty=True)
email = formencode.validators.Email(resolve_domain=True, not_empty=True)
messages = {
'tooLow': "You must be at least 18 in order to register for an event.",
'tooHigh': "You obviously are not that old. Please enter your actual age.",
}
age = formencode.validators.Int(min=18, max=999, not_empty=True, messages=messages)
我认为使用allow_extra_fields = True，如果留空/默认，它将允许函数中未提供的表单中的字段通过。我选择了应忽略的名为“听到”、“频率”和“级别”的框。
任何帮助将不胜感激。
I have a form that has some input text boxes and well as some select boxes. I have validation working perfectly on the textboxes. I don't care if any of the select boxes are left defualt or not, but everytime I submit the form it goes to a pylons error page saying "Invalid: Please enter value for ..." But I don't want that to happen.
here is my validator function:
class Registration(formencode.Schema):
allow_extra_fields=True
first_name = formencode.validators.String(strip=True, not_empty=True)
last_name = formencode.validators.String(strip=True, not_empty=True)
address = formencode.validators.String(strip=True, not_empty=True)
phone = formencode.validators.PhoneNumber(strip=True, not_empty=True)
email = formencode.validators.Email(resolve_domain=True, not_empty=True)
messages = {
'tooLow': "You must be at least 18 in order to register for an event.",
'tooHigh': "You obviously are not that old. Please enter your actual age.",
}
age = formencode.validators.Int(min=18, max=999, not_empty=True, messages=messages)
I thought with allow_extra_fields = True it would allow for fields in the form that aren't supplied in the function to pass if left blank/default. I have select boxes named heard, frequency, and level that should be ignored.
Any help here would be greatly appreciated.

在您的
formencode.validators方法中：not_empty=False。参数 not_empty false 就是你所说的：空是一个有效值。if_missing = None，这会将结果设置为None。On your
formencode.validatorsmethods:not_empty=Falseif your form is submitting the fields and the values are empty strings. The param not_empty false is how you say: empty is a valid value.if_missing = Nonewhich will set your result toNone.我认为你应该添加以下行到它
filter_extra_fields = True
I think you should add the following line to it
filter_extra_fields = True
