Field->options(), primary key and alias

milan.kratochvil · November 2018

Hello,
Using Field with a column, which is part of a compound primary key, I need to use an alias, e.g.:
Field::inst( 'a', 'b.c' )
Then, on client side I have to use

fields: [
  {
    data: 'b.c',
    name: 'a'
  }
]

( Using just name: 'b.c' I get an error: "Primary key element is not available in data set." submitting the form)

Adding the Field->options(), the options in the server response JSON are included as
options: {b.c: [{label: ..., value: ...}, {label: ..., value: ...},…]} (no dotted object notation, 'b.c' is the attribute name...)

Unfortunately, the client side is awaiting the options according to name, i.e. as
options: {a: ...}

So, opening the editor form, the select is empty...

Any idea?

The second argument to Field::inst() is both the HTTP parameter name (read on form submission) and the JSON parameter name. The client-side shouldn't see the a at all in the above case.

Can you show me your full Editor initialisation please?

server side:

$table = "s.p";
$primary = array("system", ..., "pre_id");
$editor = Editor::inst( $db, $table, $primary )
  ->fields(
      ...
      Field::inst( $table . ".pre_id", "pre.id" )
        ->options( Options::inst()
          ->table( "c.pre" )
          ->value( "pre_id" )
          ->label( "pre_text" )
        ),
      ...

client side:

var pEditor = new $.fn.dataTable.Editor( {
  ajax: "/api/s/p",
  fields: [
    ...
    {
      data: "pre.id",
      label: "pre",
      name: "s.p.pre_id",
      type: "select",
    },
    ...
  ], 
  table: "#pTable",
} );
