Feature: #97384 - TCA option "nullable"
|
|
=======================================
|
|
|
|
See :issue:`97384`
|
|
|
|
Description
|
|
===========
|
|
|
|
In order to further thin out the TCA :php:`eval` option, the `null` value has
|
|
been extracted into its own option: :php:`nullable`, which is a `boolean` value.
|
|
|
|
Example:
|
|
|
|
.. code-block:: php
|
|
|
|
'columns' => [
|
|
'nullable_column' => [
|
|
'title' => 'A nullable field',
|
|
'config' => [
|
|
'nullable' => true,
|
|
'eval' => 'trim',
|
|
],
|
|
],
|
|
],
|
|
|
|
Impact
|
|
======
|
|
|
|
It is now possible to define TCA fields as nullable by setting the
|
|
:php:`nullable` option to :php:`true`. The database field should have the
|
|
according :sql:`NULL` option set.
