Question

我具有与下一个相似的架构：

my = ngfw_validator()
class network_interface(my.Schema):
    type = my.fields.String(required = True, validate = [my.validate.OneOf(['ethernet','bridge','range','bonding','gre'])])

### I want like this if condition
### but, 'type' is <fields.String(default=<marshmallow.missing>, attribute=None, validate=[<OneOf(choices=['ethernet', 'bridge', 'range', 'bonding', 'gre'], labels=[], error=u'Not a valid choice.')>], required=True, load_only=False, dump_only=False, missing=<marshmallow.missing>, allow_none=False, error_messages={u'validator_failed': u'Invalid value.', u'required': u'Missing data for required field.', u'null': u'Field may not be null.', u'invalid_utf8': u'Not a valid utf-8 string.', u'invalid': u'Not a valid string.'})>   
### so,, I can't check if condition ... 
 if type == 'ethernet' :
    mode = my.fields.String(required = True, validate = [my.validate.OneOf(['static','dhcp','pppoe'])], allow_none=True)
    if mode is None :
        zone = my.fields.String(required = True, validate = [my.validate.OneOf(['ANY','Trust','Untrust','DMZ','PAN'])])
....

您看到了吗？这就是我想做的。我无论如何都喜欢。但是，我认为必须使用if条件。

所以我尝试了..但对我没用。

1）使用@pre_load

class network_interface(my.Schema):
...
@pre_load
def pre_check (self, data):
    data['type'] #print 'type' real values, ex) 'ethernet' 
    # but i can't validate in here

我这样打

user_data = [{
"ipv4" : "192.168.0.1/255.255.255.0",
"ipv6" : "fc00::0090:0b66:2011/64",
"type" : "Bridge",
"mode" : 'dhcp'
}]

try:
    network_interface(many=True).load(user_data)
except my.ValidationError as err:
     print err.valid_data

如果您可以教我该怎么做，非常感谢。

可以在python棉花糖中实现有效吗？
