Description of problem:

I have a DB table with a couple hundred thousand rows that I am displaying to the user.
I have a few custom filters that when changed, just does a table.ajax.reload() which works perfectly.

But with the next version I'm releasing, I've added another filter which needs to do a group by which I know is not possible with Editor yet. So I'm using raw sql here

When the new filter is applied, and the response is from the raw sql - I cannot do an ajax.reload() because the columns change slightly, thus giving me an ajax/json error. So I need to destroy and then reinitialize the table. This works but just doesn't look good on the client side at all.

Here is my code for the 2 instances:

Without the filter (read directly from table - no group by needed):
JSON:
{"data":[{"DT_RowId":"row_18","performance_table":{date: "2022-05-28", tenant: "Coledon", cli: "+27716877497", attempts: "3", successful: "0",…}]
Is there a way to remove ","performance_table":{ from the response?
PHP:

$editor = Editor::inst($db, 'performance_table');
      $editor->field(
            Field::inst('performance_table.date'),
            Field::inst('performance_table.tenant'),
            Field::inst('performance_table.cli'),
            Field::inst('performance_table.attempts'),
            Field::inst('performance_table.successful'),
            Field::inst('performance_table.cancelled'),
            Field::inst('performance_table.noanswer'),
            Field::inst('performance_table.busy'),
            Field::inst('performance_table.failed'),
            Field::inst('performance_table.asr')
      );// End Fields
      $editor->where(function ($q) use ($startDate, $endDate) {
            $q->where('performance_table.date', $startDate, '>=')
            ->and_where('performance_table.date', $endDate, '<=');
      });
      if ($truecaller){ /* Defined at the top of my script */
        $editor->leftJoin( 'master', 'master.cli', '=', 'performance_table.cli' );
        $editor->where('master.truecaller', '1', '=');
  
      }
      $editor->tryCatch(false); 
      $editor->debug(true);
      $editor->process($_POST);
      $editor->json();

With the new filter (raw sql - group by needed):
JSON:
{"data":[{date: "2022-05-28", tenant: "Coledon", cli: "+27716877497", attempts: "3", successful: "0",…}]

PHP:

$sql = "SELECT date AS date,
 performance_table.tenant as tenant, 
performance_table.cli as cli, 
SUM(performance_table.attempts) AS attempts, 
SUM(performance_table.successful) AS successful, 
SUM(performance_table.cancelled) AS cancelled, 
SUM(performance_table.noanswer) AS noanswer, 
SUM(performance_table.busy) AS busy, 
SUM(performance_table.failed) AS failed, 
ROUND(AVG(performance_table.asr), 0) AS asr 

FROM performance_table 

JOIN master ON master.cli = performance_table.cli 

WHERE master.truecaller = 1 AND date BETWEEN '$startDate' AND '$endDate' 
GROUP BY performance_table.cli ";
     

        $data = $db->sql( $sql)->fetchAll();

        echo json_encode( [
            "data" => $data
          ] );

How I define my columns in javascript:

columns: "cli" == groupby && gb_state && "cli" == gb_state ?
    columns = [
            { data: "date" },
            { data: "tenant" },
            { data: "cli" },
            { data: "attempts" },
            { data: "successful" },
            { data: "cancelled" },
            { data: "noanswer" },
            { data: "busy" },
            { data: "failed" },
            { data: "asr" },
     ] : columns = [
            { data: "performance_table.date" },
            { data: "performance_table.tenant" },
            { data: "performance_table.cli" },
            { data: "performance_table.attempts" },
            { data: "performance_table.successful" },
            { data: "performance_table.cancelled" },
            { data: "performance_table.noanswer" },
            { data: "performance_table.busy" },
            { data: "performance_table.failed" },
            { data: "performance_table.asr" },
    ],

Is there a way I could prevent the table name being in the json response so I could do a reload instead?

    Answer ✓

    The Field->name() method can be used to alter the JSON property name.

    Field::inst('performance_table.date')
    

    Is really a shorthand for:

    new Field()
      ->dbField('performance_table.date')
      ->name('performance_table.date')
    

    So what you could do is:

    Field::inst('performance_table.date')
      ->name('date')
