## Overview {#overview}
|
|
|
|
- `DataList::column()` now returns all values and not just "distinct" values from a column as per the API docs
|
|
- `DataList`, `ArrayList` and `UnsavedRalationList` all have `columnUnique()` method for fetching distinct column values
|
|
- Take care with `stageChildren()` overrides. `Hierarchy::numChildren() ` results will only make use of `stageChildren()` customisations that are applied to the base class and don't include record-specific behaviour.
|
|
- New React-based search UI for the CMS, Asset-Admin, GridFields and ModelAdmins.
|
|
- A new `GridFieldLazyLoader` component can be added to `GridField`. This will delay the fetching of data until the user access the container Tab of the GridField.
|
|

## Upgrading {#upgrading}
|
|
|
|
### Fetching distinct column values on DataList
|
|
|
|
Prior to this release `DataList` would erroneously return a distinct list of values from a column on an object.
|
|
If this behaviour is still required, please use `columnUnique()` instead.
|
|
|
|
### Using legacy GridField search API
|
|
|
|
GridFields now default to using the new search UI which uses [SilverStripe's FormSchema API](api:SilverStripe\Forms\Schema\FormSchema).
|
|
|
|
If you would rather continue using the old search API, you can remove the default `GridFieldFilterHeader` from your GridField configuration and replace with one whose _legacy_ flag has been enabled.
|
|
|
|
To enable the legacy search API on a `GridFieldFilterHeader`, you can either:
|
|
* set the `useLegacyFilterHeader` property to `true`,
|
|
* or pass `true` to the first argument of its constructor.
|
|
|
|
```php
|
|
public function getCMSFields()
|
|
{
|
|
$fields = parent::getCMSFields();
|
|
|
|
// Configure grid field to use legacy search API
|
|
$config = new GridFieldConfig_RecordEditor();
|
|
$config->getComponentsByType(GridFieldFilterHeader::class)->useLegacyFilterHeader = true;
|
|
|
|
$grid = GridField::create('Companies', 'Companies', DataList::create(Company::class), $config);
|
|
$fields->addFieldToTab('Root.Company', $grid);
|
|
|
|
return $fields;
|
|
}
|
|
|
|
```
