Customize the experimental data upload

You may customize the data upload using Datagrok functions and meta.uploadFunc tag. The function mentioned in this tag will be called on clicking button instead of the basic data upload. You may use it to extract the experimental data from the external resource (e.g., a database). Extracted data could be saved to the history or could be used directly to compare the computed and experimental results.

Enabling custom data upload

Your script header

//meta.uploadFunc: Compute:CustomUploader

Widget generator

package.ts

//name: CustomUploader
//input: object params
//output: widget uploadWidget
//output: funccall uploadFuncCall
export async function CustomUploader(params: {func: DG.Func}) {
  const uploadFunc = await grok.functions.eval('Compute:DataExtractor') as DG.Func;
  const uploadFuncCall = uploadFunc.prepare({func: params.func})
  const uploadBtn = ui.bigButton('Click me to get mock calls', () => uploadFuncCall.call());

  const dummyWidget = DG.Widget.fromRoot(ui.panel([ui.divV([
    ui.label('This part of dialog comes from my custom data uploader'),
    ui.divH([uploadBtn], {style: {'justify-content': 'center'}})
  ])]));  

  const setLoadingSub = grok.functions.onBeforeRunAction.pipe(
    filter((call) => call.id === uploadFuncCall.id)
  ).subscribe(() => {
    ui.setUpdateIndicator(uploadBtn, true);
  })

  const unsetLoadingSub = grok.functions.onAfterRunAction.pipe(
    filter((call) => call.id === uploadFuncCall.id)
  ).subscribe(() => {
    ui.setUpdateIndicator(uploadBtn, false);
  })

  dummyWidget.subs.push(setLoadingSub, unsetLoadingSub)

  return {uploadWidget: dummyWidget, uploadFuncCall};
}

Data extractor

package.ts

//name: DataExtractor
//input: func func
//output: object uploadedCalls
export async function DataExtractor(func: DG.Func) {
  await new Promise((r) => setTimeout(r, 1000));

  const dummyFunccall = await func.prepare({
    'ambTemp': 22,
    'initTemp': 100,
    'desiredTemp': 30,
    'area': 0.06,
    'heatCap': 4200,
    'heatTransferCoeff': 8.3,
    'simTime': 21600,
    }).call();
    
  return [dummyFunccall]
}

info

The custom upload funcion should return uploadWidget (of type DG.Widget) and uploadFuncCall (of type DG.FuncCall). uploadWidget will be shown on the UI; uploadFuncCall, in turn, should return the experimental runs typed as array of DG.FuncCalls.
