Flask-Enterprise - soap how to return class


I wanted to use flask-Enterprise but I was not able to find any documentation or some examples. It is easy if I want to return primitive type, but if I'd like to return class, I am not able to do that.

from soaplib.core.model.clazz import ClassModelBase
from flaskext.enterprise import Enterprise
from flask import Flask, render_template

#config Flask Enterprise
enterprise = Enterprise(app)
String = enterprise._sp.String
Integer = enterprise._sp.Integer
Boolean = enterprise._sp.Boolean
Array = enterprise._scls.Array

class T(ClassModelBase):
  date=""
  time=""

class Service(enterprise.SOAPService):
  """Soap Service Class

 Attributes:
    __soap_target_namespace__ : namespace for soap service
    __soap_server_address__ : address of soap service
  """
  __soap_target_namespace__ = 'TNS'
  __soap_server_address__ = '/soap'

@enterprise.soap(String, _returns=Integer)
def reg(self, strIdent):
  """ 
  Args:
    strIdent : string
  Returns:
    retrurn an int
  """
  return 1

@enterprise.soap(String,_returns=Array(T))
def getT(self, strIdent):
    """ 
    Args:
        strIdent : string

    Returns:
        return an array of classes
    """
    arr=[]
    arr.append(T(date="12.09.", time="17:00"))
    arr.append(T(date="13.09.", time="18:00"))
    return arr

Service reg works as it should, service getT has error

Solution

  • Declare class T as ( I expect that date and time are strings, otherwise replace it with any primitive type)

    from soaplib.core.model.clazz import ClassModel
    
    class T(ClassModel):
      date = String
      time = String
    

    and rest of your code is correct. It should work
