Method Detail
__construct() public ¶
__construct(?array $locations)
Constructor.
Parameters
-
array|null$locations optional Locations where tables should be looked for. If none provided, the default
Model\Tableunder your app's namespace is used.
_create() protected ¶
_create(array $options)
Wrapper for creating table instances
Parameters
-
array$options The alias to check for.
Returns
\Cake\ORM\Table_getClassName() protected ¶
_getClassName(string $alias, array $options)
Gets the table class name.
Parameters
-
string$alias The alias name you want to get. Should be in CamelCase format.
-
array$options optional Table options array.
Returns
string|nulladdLocation() public ¶
addLocation(string $location)
Adds a location where tables should be looked for.
Parameters
-
string$location Location to add.
Returns
$thisexists() public ¶
exists(string $alias)
Check to see if an instance exists in the registry.
Parameters
-
string$alias The alias to check for.
Returns
boolgenericInstances() public ¶
genericInstances()
Returns the list of tables that were created by this registry that could not be instantiated from a specific subclass. This method is useful for debugging common mistakes when setting up associations or created new table classes.
Returns
\Cake\ORM\Table[]get() public ¶
get(string $alias, array $options)
Get a table instance from the registry.
Tables are only created once until the registry is flushed. This means that aliases must be unique across your application. This is important because table associations are resolved at runtime and cyclic references need to be handled correctly.
The options that can be passed are the same as in Cake\ORM\Table::__construct(), but the
className key is also recognized.
Options
classNameDefine the specific class name to use. If undefined, CakePHP will generate the class name based on the alias. For example 'Users' would result inApp\Model\Table\UsersTablebeing used. If this class does not exist, then the defaultCake\ORM\Tableclass will be used. By setting theclassNameoption you can define the specific class to use. The className option supports plugin short class references {@link \Cake\Core\App::shortName()}.tableDefine the table name to use. If undefined, this option will default to the underscored version of the alias name.connectionInject the specific connection object to use. If this option andconnectionNameare undefined, The table class'defaultConnectionName()method will be invoked to fetch the connection name.connectionNameDefine the connection name to use. The named connection will be fetched from {@link \Cake\Datasource\ConnectionManager}.
Note If your $alias uses plugin syntax only the name part will be used as
key in the registry. This means that if two plugins, or a plugin and app provide
the same alias, the registry will only store the first instance.
Parameters
-
string$alias The alias name you want to get. Should be in CamelCase format.
-
array$options optional The options you want to build the table with. If a table has already been loaded the options will be ignored.
Returns
\Cake\ORM\TableThrows
RuntimeExceptionWhen you try to configure an alias that already exists.
getConfig() public ¶
getConfig(?string $alias)

Returns
\Cake\ORM\TablesetConfig() public ¶
setConfig(mixed $alias, mixed $options)
