Python Flask RestPlus 枚举类型

Question

Am using python 3.4. I have created an enum type as shown below:

import enum
class EnumGender(enum.Enum):
    blank = ' '
    female = 'Female'
    male = 'Male'
    other = 'Other'

my question is how do i assign it to flask-restplus field as the only examples i can see are:

fields.String(description='The object type', enum=['A', 'B'])

Answer 1

您可以为其分配成员名称：

fields.String(description='The object type', enum=EnumGender._member_names_)

Answer 2

I have opted for this approach:

fields.String(attribute=lambda x: str(EnumGender(x.FieldContainingEnum).name))

(Source: How to get back name of the enum element in python? )

Answer 3

Another possibility, Python 3.7.3 (circa Nov 2019):

fields.String(description="The object type",
              enum=[x.name for x in EnumGender])

Answer 4

in my case having enum like this:

from enum import Enum


class SubscriptionEvent(Enum):
    on_success = "ON_SUCCESS"
    on_error = "ON_ERROR"

I needed definition in marshal like this:

subscription_action_serializer = api.model('SubscriptionAction', {
    'event': fields.String(enum=[x.value for x in SubscriptionEvent], attribute='event.value'),
})

I needed just accept and present as valid enum values "ON_SUCCESS", "ON_SUCCESS"
