Handsontable editing nested array


Handsontable editing nested array

it helps some times I believe that you are facing a bug here when trying to put an Array in a Cell but I cannot find anywhere in the handsontable documentation or any thread in their GitHub mentioning this issue... IMO, putting an Array in a Cell is suppose to be use as Source and not Data, which result in a cell that you can't edit (hence the events afterChange/beforeChange not triggered). In your example the third line is working because of the 'null' value which is not an Array.
Anyway, the only workaround I managed to do for you is to modify your data after you define your data structure (in order to respect your condition, but I strongly advice do modify them anyway because you will need to do that eventually).
code :
var data1 = [];
for (var i=0; i<data.length;i++) {
  if (data[i].tags != null) {
    var temp = data[i].tags[0];
    temp = temp.concat(',');
    temp = temp.concat(data[i].tags[1]);
  } else var temp = null;
  data1.push({ id: data[i].id, name: data[i].name, price: data[i].price, tags: temp });
}

it helps some times It's very hard to follow what you're doing with your data, what with all those nested loops and hard coded values. But here is what's going on, more or less.
The 'contains' error has to do with the way you're supplying the data sources. The editor will try and edit the data source when you open it. However, if it is undefined, then it will inevitably throw an error, in this case it does some sort of check with contains and throws when it goes undefined.contains().

this will help You could store the data in a reactiveValues and have two observers updating it; one if the button is clicked, one if the table is edited by hand.
In your output$table and output$result, you then just need to use the data that is in the reactiveValues. Here's an example (same ui.R as you posted):
code :
server <- function(input,output,session)({
  values <- reactiveValues(data=as.data.frame(runif(2)))

  observe({
    input$recalc
    values$data <- as.data.frame(runif(2))
  })

  observe({
    if(!is.null(input$table))
     values$data <- hot_to_r(input$table)
  })


  output$table <- renderRHandsontable({
    rhandsontable(values$data)
    })


  output$result <- renderText({ 
    sum(values$data)
  })
})

it helps some times If you don't want to create new updated array recursively you can use references. The following code walks through the given array and on each iteration changes the reference to the nested array until it reaches the field you want to change.
code :
function setInDict(array $array, array $path, $value)
{
    if (!$path) {
        return $array;
    }

    $found = &$array;
    foreach ($path as $field) {
        if (!isset($found[$field]) || !array_key_exists($field, $found)) {
            throw new \InvalidArgumentException("There is no nested field '$field' in the given array");
        }

        $found = &$found[$field];
    }

    $found = $value;

    return $array;
}

To fix the issue you can do What your facing on this is supposed to be a pretty old fixed issue. After several test/research, I have indeed the same behavior on my project if I active the manualColumnMove option.
So what I am proposing to you is to pick one of these two solutions :
code :
hot.addHook('afterColumnMove', function(sourceIndex, targetIndex) {
  var
  sourceValues = hot.getData(0,sourceIndex,hot.getData().length,sourceIndex),
  sourceProperties =hot.getSettings().columns[sourceIndex],
  sourceHeader=hot.getSettings().colHeaders[sourceIndex],
  targetValues = hot.getData(0,targetIndex,hot.getData().length,targetIndex),
  targetProperties =hot.getSettings().columns[targetIndex],
  targetHeader=hot.getSettings().colHeaders[targetIndex],

  newColumns=hot.getSettings().columns,
  newHeaders=hot.getSettings().colHeaders;

  newHeaders[sourceIndex]=targetHeader;
  newHeaders[targetIndex]=sourceHeader;
  newColumns[sourceIndex]=targetProperties;
  newColumns[targetIndex]=sourceProperties;

  hot.updateSettings({columns:newColumns,colHeaders:newHeaders});
  hot.populateFromArray(0,sourceIndex,sourceValues,hot.getData().length,sourceIndex);
  hot.populateFromArray(0,targetIndex,targetValues,hot.getData().length,targetIndex);
});

With these it helps It might look something like this to get a basic autocomplete in your template
code :
<hot-table>
    <hot-column type="autocomplete"
                [source]="['somevalues','here']"
                [strict]="true/false"
    >
    </hot-column>
</hot-table>
