Hello,
we have evaluated your OpenAPI generator. The generated code is really well so far. But we had also identified, that it can't handle Dictionaries which are declared by additionalProperties in OAS 3 (https://swagger.io/docs/specification/data-models/dictionaries/)
For example, the following spec:
Is rendered to this "empty" class:
Do you have any plans to implement the support for additionalProperties?

Do you have any plans to implement the support for additionalProperties?

Hi,
Could you provide the full spec with this data? I will test here and implement for the next release if needed.

Sergio

Hi,
Thanks for the link, I'll read the documentation and try to implement it. I will let you know.

Hello,
Unfortunately the JSON parser doesn't allow to parse Dictionaries in a standard way, the Embarcaderon JSON adds some additional properties and although I tried to implement custom interceptors the result was not the desired, so finally I implemented a partial support for Additional Properties, this is explained in the following article:
https://www.esegece.com/help/sgcWebSockets/#t=OpenAPI%2FParser%2FSchemas%2FOpenAPI_Additional_Properties.htm

Hi Sergio,
thank you for this release.
I have read your article, some times, but still don't understand how the way from JSON to AdditionalProperties works.
Given this JSON:
and this generated classes:
After the successful request, Metadata is always nil.
Can you give me an example, how it should work?

Hello,
Using the following code, works well
Which method are you using to send the request? Retrieve_Organization?
Kind Regards,

Using the following code, works well
var
i: Integer;
oResponse: TsgcOpenAPI_OrganizationResponse_Class;
begin
oResponse := TsgcOpenAPI_OrganizationResponse_Class.Read(
' {"_id": "5b8cb290-0901-4435-9131-576695fab511", "metadata": {"KdNr": "10001", "AdGuid": "420739B4-3B2F-4DD1-BCB2-48997EEE930C"}}');
for i := 0 to oResponse.Metadata.Dictionary.Count - 1 do
begin
ShowMessage(oResponse.Metadata.Dictionary.ToArray[i].Key + '=' + oResponse.Metadata.Dictionary.ToArray[i].Value);
end;
Which method are you using to send the request? Retrieve_Organization?

Hi,
I have tried...in your example, after TsgcOpenAPI_OrganizationResponse_Class.Read, oResponse.Metadata is nil. I would post a screenshot, but it isn't possible to upload images here.
Further I don't understand how it could work if the ObjectReverter is implemented as follows:
and the inherited method in REST.JsonReflect is empty.
Maybe some code is not released?

Hi,
I am not using the ObjectReverter because as I told in a previous message, the Embarcadero JSON implementation doesn't allow to read a JSON Dictionary in a standard way. I just let this code if later I can found a workarround, but now it's not used.
Could you send me the JSON response you get? and which HTTP method are you requesting? I will test here.
Kind Regards,
Sergio

Hi,
if you say that your example works for you, how is Metadata/TsgcOpenAPI_AdditionalProperties unserialized?
I'm confused of the real code and your statement, I must oversee something.
Ok, but here is the Json:
The call was made from this (generated) code:
and here also the generated protected method
I hope this helps...

Hi,
I see the problem, one unit was not synchronized, so it was not working as expected, it was my fault. I've recompiled the setup, so please download again and reimport the openAPI specification.
The Metadata dictionary is unserialized in the method: TsgcOpenAPI_OrganizationResponse_Class.Read
Sorry for the inconvenience.
Kind Regards,
Sergio

Hi Sergio,
now it works. Thank you!
But I am afraid that the solution is very inefficient, because for each dictionary the DoLoadDictionary is called which gets the raw Json, so the not so cheap unmarshalling process is done again and again.
For now I can live with this solution, but maybe I find an other way, an efficient one.
It return, maybe we can get the sources for the OpenAPI parser? ;-)

Hi,
Yes, I know it's not a good solution, but after working several days with that I finally implement this temporary solution until I find something better. If you find a better solution I will appreciate if you share it. Thanks for the feedback.

Hi Sergio,
the REST.JsonReflect framework already creates an TsgcOpenAPI_AdditionalProperties when it parses the Json, but it is ignored by the TsgcAdditionalPropertiesInterceptor and is also not released (next memory leak).
So I have the following suggest for this issue:

Waldemar

Hi,
Yes, you are right, there was a memory leak there. I've updated the latest beta with your fix, thanks again for the feedback.
