Help with int64 & date-time

[jona7o]

Hi,
i tried to implement the api in a project, but i have some problems with the data types:

When i send a number i get (integer & format: int64 in swagger):

play.api.http.HttpErrorHandlerExceptions$$anon$1: Execution exception[[ClassCastException: java.lang.Integer cannot be cast to java.lang.Long]]

and when i send a date-time object from swagger i get:

play.api.http.HttpErrorHandlerExceptions$$anon$1: Execution exception[[JsonMappingException: Can not instantiate value of type [simple type, class java.time.ZonedDateTime] from String value ('2017-03-25T11:58:04.522Z'); no single-String constructor/factory method at [Source: [B@4dc50d3; line: 17, column: 14] (through reference chain: Contact["created"])]]

Do you have an idea what's the problem?

Greetings Tobias

Hey @jona7o, it would be very helpful if you could provide the full specification which is failing or if not possible at least relevant parts of it and full stacktraces.

Hi, here are the relevant parts of the swagger file (i choose a smaller entity - but the error is the same):

definition:
Note: type: object properties: id: type: integer format: int64 owningPersonId: type: integer format: int64 owningCompanyId: type: integer format: int64 created: type: string format: date-time modified: type: string format: date-time responsible: type: string text: type: string popup: type: boolean read: type: boolean completed: type: boolean
and path:
/notes: post: tags: - Note operationId: addNote description: Create a new Note consumes: - application/json produces: - application/json parameters: - in: body name: noteToCreate required: true schema: $ref : '#/definitions/Note' responses: 201: description: Created 400: description: Bad Request

the "generated" code:

val addNote = addNoteAction { (noteToCreate: Note) => // ----- Start of unmanaged code area for action ManagementYaml.addNote Services.noteService.insert(NoteRowConverter > noteToCreate) // ----- End of unmanaged code area for action ManagementYaml.addNote }

via swagger ui i send a post with sample data:
{ "owningPersonId": 12, "owningCompanyId": 13, "created": "2017-03-26T12:16:38.622Z", "modified": "2017-03-26T12:16:38.622Z", "responsible": "string test", "text": "hope you can help me - great plugin :)", "popup": true, "read": true, "completed": true }

and the error:

[slavaschmidt]

The first issue is related to the #56, the fix should be a low hanging fruit.

The second issue unfortunately is more involving and related to the way play validations is used.

[s12v]

@jona7o, we had a similar issue with int64, and it seems to be fixed in 0.2.0

[slavaschmidt]

@s12v, I guess we starting to have more and more issues like when generated code compiles and runs but fails at the runtime. I'll create a test environment for such issues so that we can be sure we are won't introduce regression in future versions.
