Manages and loads instances of Connection
Provides an interface to loading and creating connection objects. Acts as a registry for the connections defined in an application.
Provides an interface for loading and enumerating connections defined in config/app.php
string[]A map of connection aliases.
arrayConfiguration sets.
string[]An array mapping url schemes to fully qualified driver class names
\Cake\Datasource\ConnectionRegistryThe ConnectionRegistry used by the manager.
alias(string $alias, string $source)
Set one or more connection aliases.
Connection aliases allow you to rename active connections without overwriting the aliased connection. This is most useful in the test-suite for replacing connections with their test variant.
Defined aliases will take precedence over normal connection names. For example, if you alias 'default' to 'test', fetching 'default' will always return the 'test' connection as long as the alias is defined.
You can remove aliases with ConnectionManager::dropAlias().
// Make 'things' resolve to 'test_things' connection
ConnectionManager::alias('test_things', 'things'); string $alias The alias to add. Fetching $source will return $alias when loaded with get.
string $source The connection to add an alias to.
Cake\Datasource\Exception\MissingDatasourceConfigExceptionconfigured()
Returns an array containing the named configurations
string[]Array of configurations.
drop(string $config)
Drops a constructed adapter.
If you wish to modify an existing configuration, you should drop it, change configuration and then re-add it.
If the implementing objects supports a $_registry object the named configuration will also be unloaded from the registry.
string $config An existing configuration you wish to remove.
boolSuccess of the removal, returns false when the config does not exist.
dropAlias(string $name)
Drop an alias.
Removes an alias from ConnectionManager. Fetching the aliased connection may fail if there is no other connection with that name.
string $name The connection name to remove aliases for.
get(string $name, bool $useAliases)
Get a connection.
If the connection has not been constructed an instance will be added to the registry. This method will use any aliases that have been defined. If you want the original unaliased connections pass false as second parameter.
string $name The connection name.
bool $useAliases optional Set to false to not use aliased connections.
\Cake\Datasource\ConnectionInterfaceA connection object.
Cake\Datasource\Exception\MissingDatasourceConfigExceptiongetConfig(string $key)
Reads existing configuration.
string $key The name of the configuration.
mixed|nullConfiguration data at the named key or null if the key does not exist.
getConfigOrFail(string $key)
Reads existing configuration for a specific key.
The config value for this key must exist, it can never be null.
string $key The name of the configuration.
mixedConfiguration data at the named key.
InvalidArgumentExceptiongetDsnClassMap()
Returns the DSN class map for this class.
string[]parseDsn(string $config)
Parses a DSN into a valid connection configuration
This method allows setting a DSN using formatting similar to that used by PEAR::DB. The following is an example of its usage:
$dsn = 'mysql://user:pass@localhost/database'; $config = ConnectionManager::parseDsn($dsn); $dsn = 'Cake\Database\Driver\Mysql://localhost:3306/database?className=Cake\Database\Connection'; $config = ConnectionManager::parseDsn($dsn); $dsn = 'Cake\Database\Connection://localhost:3306/database?driver=Cake\Database\Driver\Mysql'; $config = ConnectionManager::parseDsn($dsn);
For all classes, the value of scheme is set as the value of both the className and driver unless they have been otherwise specified.
Note that query-string arguments are also parsed and set as values in the returned configuration.
string $config The DSN string to convert to a configuration array
arrayThe configuration array to be stored after parsing the DSN
setConfig(mixed $key, mixed $config)
Configure a new connection object.
The connection will not be constructed until it is first used.
string|array $key The name of the connection config, or an array of multiple configs.
array|null $config optional An array of name => config data for adapter.
Cake\Core\Exception\ExceptionsetDsnClassMap(array $map)
Updates the DSN class map for this class.
string[] $map Additions/edits to the class map to apply.
A map of connection aliases.
string[]Configuration sets.
arrayAn array mapping url schemes to fully qualified driver class names
string[]The ConnectionRegistry used by the manager.
