Hi I tried with the code you suggested, but onSuccess( line no 19) is not working, Can you suggest how to save the value of process variable?

Hi,
In my opinion it is not a lot of work (~5 Appian Objects to specify). From my experience (we have implemented this), there is no performance impact at all.

It's too much of work and just like you said it's too sophisticated leads to performance issues

It is sophisticated, but it is possible to call a process model without user interaction on page load, e. g. :

local!docID: call_IntegrationObject (which calls a WebAPI), The WebAPI is calling the desired process model.

This executes the process model every time the UI is loaded.

Yes, to some extent, in my case I will save the image in an Artifact folder, and from next time onwards I will check for the image if it is already generated then I will use the image and display it like above else I will generate a new one and display that, as you have done.

Now i get what you wanted ,You want to generate and show QR code in a single interface isn't it? , Correct me if i'm wrong.

I would like to suggest small changes to above design. Design the main interafce like in below snippet.

{
  a!cardLayout(
    contents: {
      a!documentViewerField(
        label: "Document Viewer",
        labelPosition: "ABOVE",
        document: ri!document,
        height: "MEDIUM",
        showWhen: a!isNotNullOrEmpty(ri!document)
      ),
      a!buttonArrayLayout(
        buttons: {
          a!buttonWidget(
            label: "Generate QR code",
            style: "OUTLINE",
            showWhen: a!isNullOrEmpty(ri!document),
            saveInto: a!startProcess(
              processModel: "Your process model",
              onSuccess: a!save(ri!document,fv!processInfo.pv.generatedqr)
            )
          )
        },
        align: "START",
        marginBelow: "NONE"
      )
    },
    height: "AUTO",
    style: "TRANSPARENT",
    marginBelow: "STANDARD"
  )
}

Process model is required , there is no function provided in that plugin. On Page load we can't start a process.For starting a process we need an interaction

Thanks a ton. I have one more question related to this, Is it possible to call that Generate QR Code without defining a process model? Or Is it possible to call the process model on page load?

If you don't want to save the document in DB , Design a process model like this

save the Generated document in a process variable (It stores Document ID)

Design a Interface with either documentviewer field or Image field

Call the interface In the user input task (Process model ) pass the generated qr

Want to know how to handle the generated document? Or Displaying the Generated Document into an interface.

venkatrea696188 — Fri, 29 Dec 2023 09:35:58 GMT

I don't get it , you are asking for interface component to show a saved document or way handle generated document. If You are looking for Interface component you can use "Document Viewer field" or "image field ".

1. User Input Task after Generate QR Code node. Just pass the generated document.

2. If you are saving generated document in DB , Get the Document ID from there .

3. Create a Constant for generated document and reference the constant

Sowvik Roy — Fri, 29 Dec 2023 09:20:50 GMT

Yes, But how to show the generated image in my interface?

venkatrea696188 — Fri, 29 Dec 2023 09:16:38 GMT

Generate QR Code & Bar Code smart services are there (Plug In) , that smart service saves the generated files in a target folder . Showing it in a user Interface you can handle it in multiple ways .One would be user input task after generation

RE: How do I display an image saved in an Appian folder

Sowvik Roy — Fri, 29 Dec 2023 09:07:27 GMT

How about the dynamic image stored in the artifact folder? Like if I have smart service to generate a QR code and want use the generated QR code in my interface how to do that.

I'd suggest using a constant to reference your document. Then, it will be easier to use it within any interface on any environment. For example, suppose I upload a document called My Logo. Then, I'd create a constant to point to it like this:

Then, you can reference it in any interface using the a!documentImage() function:

a!imageField(
  images: a!documentImage(
    document: cons!PDL_DOC_MY_LOGO
  )
)

If that doesn't work, can you provide more information about what you have tried?
