Ampersand for "label"

[HemulGM]

I use the generator on the site.

When generating a field with the name "label", an ampersand is necessary like with the field "type".

[JensBorrisholt]

@HemulGM have a look at my branch https://github.com/JensBorrisholt/Delphi-JsonToDelphiClass

I've fixed that there.

New with JSON and Delphi, piece of cake with VS C# , however this is becoming a nightmare in delphi. The & causes a small "sET" in my generated file. Must be a "SET" to match the label when reading from .dot module. Is there a simple way around it. TJsonDTO is great to read an existing JSON file but a pain to generate. Is there a function to extract the contents into a TStringList so I can pretty-write to a file? Thanks in advance James

JSON and its mechanics have nothing to do with it. This is a reserved word and there are exactly the same problems with them in C#.

[JACAmetekDenmark]

Thanks for the quick reply. Protocol and communications DLL (to the device) are developed in C# with no conflicts, it's only now a problem with reserved word clashes in Delphi, when integrating the host systems developed in Delphi. It never occurred to me it would be an issue with delphi. Thanks anyway.

No one is stopping you from not using reserved words at all. Delphi serialization, like everywhere else, works with attributes, through which you can specify any field name from JSON for a field in a class.

Hi @JACAmetekDenmark

I'm not exactly sure what the issue are. Could you provide me with an example?

Just send it direct to GitHUB@Borrisholt.dk

Hej Jens, our latest calibrator series communication is based on JSON. (new to me). The communication to this and older models are developed in C# (.NET) through a Hydra wrapper because our host programs are in Delphi(non protected). All works fine however one feature called workorders require very large amount of data, so I used xml files to be read by host. I wanted to do the same with JSON files. All was well while testing with host C# programs. Because the defined protocol contains reserved words ie. “SET”, “Unit” & “Value” the Jsontodelphi generator defines Them with ampersands “sET”, “unit” & “value” , the file cannot be parsed as the nodes don’t match.

{ "SET":"AddWorkOrder", "TestType":"Calibration", "WO_GUID":"", "ID":"copy Temp pt100", "CompanyName":"Ametek Denmark", : : }

I have several varying arrays in the JSON so also trying to get my head around the [GenericListReflect] TArray/TObjectList representation.

It just seems very complicated in Delphi. Have enclosed a file generated by the .Net server DLL.

Regards James

thanks for the heads up on attributes Is there a help source I can refer to before spamming you with questions? Have 2 which is the correct method to set a value? AddWorkOrder.AsJson:= '{ "SET":"AddWorkOrder" } '; &SET:='AddWorkOrder'; Best method to write to a file. TFile.WriteAllText('C:\Ametek\RTCRefresh\DelphiAddworker.JSON',AddWorkOrder.AsJson, TEncoding.UTF8); or Empty to TStringList then write to file? Apologies for the beginner questions. regards James

[HemulGM]

{
   "SET":"AddWorkOrder",
   "TestType":"Calibration",

   "CompanyName":"Ametek Denmark"

[JACAmetekDenmark]

Thankyou, have applied the attribute to name the component and that part is solved. However is your example manually defined or result of the generator ? if I run that short JSON text through the generator I still get a Property " &SET"

I don’t see any difficulty in correcting such fields to be acceptable. Because the property name does not affect serialization

[JACAmetekDenmark]

you haven't defined the SET component which has to be published, in your example. That is the issue.

[HemulGM]

you haven't defined the SET component which has to be published, in your example. That is the issue.

It's not a mistake. And it will work. Check

[JACAmetekDenmark]

I think you misunderstood me. I need to generate the file ... not load it. How do I set "SET" = "AddWorkorder" if there is no public access?

[JACAmetekDenmark]

Name attribute does not work on arrays, [JSONName('Sensors'), JSONMarshalled(False)] FSensorsArray: TArray; [GenericListReflect] FSensors: TObjectList;

The node in the JSON file is always "sensors"

[HemulGM]

[HemulGM]

You can set ANY property name. Its name will be taken from the private field!

[JACAmetekDenmark]

Apologies, i was only looking for the SET in the properties list, didn't see the AnyFieldName. Is there an issue with the Name attributes when applied to arrays?

Name attribute does not work on arrays,

[JSONName('Sensors'), JSONMarshalled(False)] FSensorsArray: TArray; [GenericListReflect] FSensors: TObjectList;

The node in the JSON file is always "sensors"

[HemulGM]

[JACAmetekDenmark]

Thankyou. strange both JSONName and JSONNameAttributey worked after I assigned the attributes to both the TArray and the TObjectList.

[JSONNameAttribute('Sensors'), JSONMarshalled(False)] FSensorsArray: TArray; [JSONNameAttribute('Sensors'), GenericListReflect] FSensors: TObjectList;

Very much appreciate your patience and help. All seems to work with JSON which will save me alot of time to finding another solution. regards James

[JensBorrisholt]

@JACAmetekDenmark I'm glad you got help. I was busy yesterday. You also spoked about "Is there a function to extract the contents into a TStringList so I can pretty-write to a file?"

Dig you got helt with that aswell? Or do you need a demo application.

[JACAmetekDenmark]

No we haven't touched on that. I use " TFile.WriteAllText('C:\Ametek\RTCRefresh\DelphiAddworker.JSON',AddWorkOrder.AsJson, TEncoding.UTF8);" to write to the file which works however unformatted and without indentation. So a demo or advice would be apprecated. regards James

[JensBorrisholt]

@JACAmetekDenmark can I have a copy of the file? Send it in a email, please, and I'll make you a demo.

[HemulGM]

No we haven't touched on that. I use " TFile.WriteAllText('C:\Ametek\RTCRefresh\DelphiAddworker.JSON',AddWorkOrder.AsJson, TEncoding.UTF8);" to write to the file which works however unformatted and without indentation. So a demo or advice would be apprecated. regards James

var JSON := TJSON.ObjectToJsonObject(YourObject);
try
  TFile.WriteAllText('C:\Ametek\RTCRefresh\DelphiAddworker.JSON', JSON.Format, TEncoding.UTF8);
finally
  JSON.Free;
end;

[JensBorrisholt]

@JACAmetekDenmark now I'm confused: Do you want to pretty print a JSON file (format with indentenration) or do you want do create json from a object and save that to a file?

For the latter Create (or generate) a unis that inheritets from TJsonDTO on you TJsonDTO decentant you have a property called AsJson, save that to at file.

TJSON.ObjectToJsonObject is the build in functioanllity, and have nothing to do with mit repo

[JensBorrisholt]

It seems like you are not using TJsonDTO in your exampels at all and thats where your problems starts

[JACAmetekDenmark]

Hi Jens, i inherit from TJsonDTO . here us a snippet.

TAddWorkOrder = class(TJsonDTO) private [JSONName('SET')] FSET: string; FTestType: string; [JSONName('WO_GUID')] FWOGUId: string; [JSONName('ID')] FId: string; [JSONName('Sensors'), JSONMarshalled(False)] FSensorsArray: TArray; [JSONName('Sensors'), GenericListReflect] FSensors: TObjectList; [JSONName('Scenario'), JSONMarshalled(False)]

[JSONName('ProcedureInfo')]
FProcedureInfo: TProcedureInfo;
function GetSensors: TObjectList<TSensors>;
function GetSibInputPorts: TObjectList<TSibInputPorts>;

protected function GetAsJson: string; override; published property &SET: string read FSET write FSET; property TestType: string read FTestType write FTestType; property Calibrator: TCalibrator read FCalibrator;

Regarding JSON file I want to simply save the AddWorkOrder json object to a JSON file in JSON format.

[JensBorrisholt]

@JACAmetekDenmark

I havent had time to look make sure the result are always formated but here is a smalle function for format a JSON file

function FormatJSON(json: String): String; var tmpJson: TJSONObject; begin tmpJson := TJSONObject.ParseJSONValue(json) as TJSONObject; Result := TJson.Format(tmpJson); FreeAndNil(tmpJson); end;
