Hi,
I have a problem with reverse association between the classes Address and City.
[Serializable]
[System.CodeDom.Compiler.GeneratedCode("LightSpeedModelGenerator", "1.0.0.0")]
[System.ComponentModel.DataObject]
[Table(IdColumnName = "Id", IdentityMethod = IdentityMethod.IdentityColumn)]
[DataContract(IsReference = true)]
public class Address : Entity<int>
{
private readonly EntityHolder<City> _City = new EntityHolder<City>();
}
[Serializable]
[System.CodeDom.Compiler.GeneratedCode("LightSpeedModelGenerator", "1.0.0.0")]
[System.ComponentModel.DataObject]
[Table(IdColumnName = "Id", IdentityMethod = IdentityMethod.IdentityColumn)]
[DataContract(IsReference = true)]
public class City : Entity<int>
{
private readonly EntityHolder<Address> _Address = new EntityHolder<Address>();
private int _AddressId;
}
look at error:
{
"Message": "An error has occurred.",
"ExceptionMessage": "The 'ObjectContent`1' type failed to serialize the response body for content type 'application/json; charset=utf-8'.",
"ExceptionType": "System.InvalidOperationException",
"StackTrace": null,
"InnerException": {
"Message": "An error has occurred.",
"ExceptionMessage": "Self referencing loop detected with type 'BeagleApp.Address'. Path '_City._valueChanged'.",
"ExceptionType": "Newtonsoft.Json.JsonSerializationException",
}
when I add this code:
config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
look at the mess:
{
"_PessoaId": 1,
"_CityId": 1,
"_Logradouro": "RUA CURUPACE",
"_Numero": "635",
"_Cep": 3120010,

},

}
}
},

}
any advice and suggestions will be greatly appreciated.
