flask-restplus swagger 路径选择

如何解决flask-restplus swagger 路径选择

我有一个使用flask-restplus lib的pythonflask代码：

from flask_restplus.inputs import boolean
from flask import Flask
from flask_restplus import Resource,Api,fields

app = Flask(__name__)
api = Api(app)

model = api.model('Model',{
    'id': fields.String,})

seen_search_parser = api.parser()
seen_search_parser.add_argument(
    'page',type=str,default="1",help='Page number',location='form')
seen_search_parser.add_argument(
    'maxi',type=int,default=100,help='Seen entries per page',location='form')
seen_search_parser.add_argument('local_seen',choices=['true','false','all'],default=(
    "all"),help='Filter list by local status.',location='form')


@api.route("/todo/<id>")
@api.doc(security="apikey",responses={200: "OK",400: "Invalid Argument",500: "Mapping Key Error"},)
class HelloWorld(Resource):
    @api.expect(seen_search_parser)
    def post(self,id):
        args = seen_search_parser.parse_args()
        return {'hello': args}


if __name__ == '__main__':
    app.run(debug=True)

就像swagger中的formdata（local_sceen）字段有选择一样；有没有办法使用flask_restplus在swagger中获得path（id）的选择列表？
