" * * There are a couple of lines like this: * @example Parent: =>Page.about * This will tell the system to set the ParentID database field to the ID of the Page object with the identifier ŇaboutÓ. * This can be used on any has-one or many-many relationship. * Note that we use the name of the relationship (Parent), and not the name of the database field (ParentID) * * On many-many relationships, you should specify a comma separated list of values. * @example MyRelation: =>Class.inst1,=>Class.inst2,=>Class.inst3 * An crucial thing to note is that the YAML file specifies DataObjects, not database records. * The database is populated by instantiating DataObject objects, setting the fields listed, and calling write(). * This means that any onBeforeWrite() or default value logic will be executed as part of the test. * This forms the basis of our testURLGeneration() test above. * * For example, the URLSegment value of Page.staffduplicate is the same as the URLSegment value of Page.staff. * When the fixture is set up, the URLSegment value of Page.staffduplicate will actually be my-staff-2. * * Finally, be aware that requireDefaultRecords() is not called by the database populator - * so you will need to specify standard pages such as 404 and home in your YAML file. * * * Page: * home: * Title: Home * about: * Title: About Us * staff: * Title: Staff * URLSegment: my-staff * Parent: =>Page.about * staffduplicate: * Title: Staff * URLSegment: my-staff * Parent: =>Page.about * products: * Title: Products * ErrorPage: * 404: * Title: Page not Found * ErrorCode: 404 * * * @package sapphire * @subpackage core * * @see http://spyc.sourceforge.net/ * * @todo Write unit test for YamlFixture * * @param $fixtureFile The location of the .yml fixture file, relative to the site base dir */ class YamlFixture extends Object { /** * The location of the .yml fixture file, relative to the site base dir * * @var string */ protected $fixtureFile; /** * Array of fixture items * * @var array */ protected $fixtureDictionary; function __construct($fixtureFile) { $this->fixtureFile = $fixtureFile; } /** * Get the ID of an object from the fixture. * @param $className The data class, as specified in your fixture file.
