# Class RoomServiceOrder

A single database record & abstract class for the data-access-model.

## Extensions and Decorators

See `Extension` and `DataObjectDecorator`.

## Permission Control

Object-level access control by `Permission`. Permission codes are arbitrary strings which can be selected on a group-by-group basis.

    class Article extends DataObject implements PermissionProvider {
            static $api_access = true;

            public function canView($member = false) {
                    return Permission::check('ARTICLE_VIEW');
            }
            public function canEdit($member = false) {
                    return Permission::check('ARTICLE_EDIT');
            }
            public function canDelete() {
                    return Permission::check('ARTICLE_DELETE');
            }
            public function canCreate() {
                    return Permission::check('ARTICLE_CREATE');
            }
            public function providePermissions() {
                    return array(
                            'ARTICLE_VIEW' => 'Read an article object',
                            'ARTICLE_EDIT' => 'Edit an article object',
                            'ARTICLE_DELETE' => 'Delete an article object',
                            'ARTICLE_CREATE' => 'Create an article object',
                    );
            }
    }

Object-level access control by `Group` membership:

    class Article extends DataObject {
            static $api_access = true;

            public function canView($member = false) {
                    if(!$member) $member = Member::currentUser();
            return $member->inGroup('Subscribers');
            }
            public function canEdit($member = false) {
                    if(!$member) $member = Member::currentUser();
            return $member->inGroup('Editors');
            }

            // ...
    }

If any public method on this class is prefixed with an underscore, the results are cached in memory through `ViewableData::cachedCall()`.

## Methods summary

`public array|string` | # `fieldLabels( boolean $includerelations = true )` Get any user defined searchable fields labels that exist. Allows overriding of default field names in the form interface actually presented to the user. Get any user defined searchable fields labels that exist. Allows overriding of default field names in the form interface actually presented to the user. The reason for keeping this separate from searchable_fields, which would be a logical place for this functionality, is to avoid bloating and complicating the configuration array. Currently much of this system is based on sensible defaults, and this property would generally only be set in the case of more complex relationships between data object being required in the search interface. Generates labels based on name of the field itself, if no static property `DataObject::$field_labels` exists. #### Parameters $includerelations boolean $includerelations a boolean value to indicate if the labels returned include relation fields #### Returns `array|string` Array of all element labels if no argument given, otherwise the label of the field #### Uses `mixed` ``FormField::name_to_label()`` #### Overrides `DataObject::fieldLabels`
`public` | # `onBeforeWrite( )` Event handler called before writing to the database. You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though! Event handler called before writing to the database. You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though! This called after $this->validate(), so you can be sure that your data is valid. #### Uses ``DataObjectDecorator::onBeforeWrite()`` #### Overrides `DataObject::onBeforeWrite`
`public` | # `onAfterWrite( )` Event handler called after writing to the database. You can overload this to act upon changes made to the data after it is written. $this->changed will have a record database. Don't forget to call parent::onAfterWrite(), though! Event handler called after writing to the database. You can overload this to act upon changes made to the data after it is written. $this->changed will have a record database. Don't forget to call parent::onAfterWrite(), though! #### Uses ``DataObjectDecorator::onAfterWrite()`` #### Overrides `DataObject::onAfterWrite`
`public` | # `onAfterDelete( )` #### Overrides `DataObject::onAfterDelete`
`public string` | # `getTitle( )` Standard implementation of a title/label for a specific record. Tries to find properties 'Title' or 'Name', and falls back to the 'ID'. Useful to provide user-friendly identification of a record, e.g. in errormessages or UI-selections. Standard implementation of a title/label for a specific record. Tries to find properties 'Title' or 'Name', and falls back to the 'ID'. Useful to provide user-friendly identification of a record, e.g. in errormessages or UI-selections. Overload this method to have a more specialized implementation, e.g. for an Address record this could be:
    public function getTitle() {
      return "{$this->StreetNumber} {$this->StreetName} {$this->City}";
    }
#### Returns `string` string #### Overrides `DataObject::getTitle`
`public` | # `RoomServicePrice( )`
