Class Model
Object-relational mapper.
DBO-backed object data model. Automatically selects a database table name based on a pluralized lowercase object class name (i.e. class 'User' => table 'users'; class 'Man' => table 'men') The table is required to have at least 'id auto_increment' primary key.

Method Detail
__callsource public
__call( string $method , array $params )
Handles custom method calls, like findBy<field> for DB models, and custom RPC calls for remote data sources.
Parameters
- string
$method
- Name of method to call.
- array
$params
- Parameters for the method.
Returns
mixed
Whatever is returned by called method
__constructsource public
__construct( boolean|integer|string|array $id false , string $table null , string $ds null )
Constructor. Binds the model's database table to the object.
If $id
is an array it can be used to pass several options into the model.
-
id
: The id to start the model on. -
table
: The table to use for this model. -
ds
: The connection name this model is connected to. -
name
: The name of the model eg. Post. -
alias
: The alias of the model, this is used for registering the instance in theClassRegistry
. eg.ParentThread
Overriding Model's __construct method.
When overriding Model::__construct() be careful to include and pass in all 3 of the arguments to parent::__construct($id, $table, $ds);
Dynamically creating models
You can dynamically create model instances using the $id array syntax.
$Post = new Model(array('table' => 'posts', 'name' => 'Post', 'ds' => 'connection2'));
Would create a model attached to the posts table on connection2. Dynamic model creation is useful when you want a model object that contains no associations or attached behaviors.
Parameters
- boolean|integer|string|array
$id
optional false - Set this ID for this model on startup, can also be an array of options, see above.
- string

Link
http://book.cakephp.org/2.0/en/models/retrieving-your-data.html#model-fieldfindsource public
find( string $type 'first' , array $query array() )
Queries the datasource and returns a result set array.
Used to perform find operations, where the first argument is type of find operation to perform (all / first / count / neighbors / list / threaded), second parameter options for finding (indexed array, including: 'conditions', 'limit', 'recursive', 'page', 'fields', 'offset', 'order', 'callbacks')
Eg:
$model->find('all', array( 'conditions' => array('name' => 'Thomas Anderson'), 'fields' => array('name', 'email'), 'order' => 'field3 DESC', 'recursive' => 2, 'group' => 'type', 'callbacks' => false, ));
In addition to the standard query keys above, you can provide Datasource, and behavior specific keys. For example, when using a SQL based datasource you can use the joins key to specify additional joins that should be part of the query.
$model->find('all', array( 'conditions' => array('name' => 'Thomas Anderson'), 'joins' => array( array( 'alias' => 'Thought', 'table' => 'thoughts', 'type' => 'LEFT', 'conditions' => '`Thought`.`person_id` = `Person`.`id`' ) ) ));
Disabling callbacks
The callbacks
key allows you to disable or specify the callbacks that should be run. To disable beforeFind & afterFind callbacks set 'callbacks' => false
in your options. You can also set the callbacks option to 'before' or 'after' to enable only the specified callback.
Adding new find types
Behaviors and find types can also define custom finder keys which are passed into find(). See the documentation for custom find types (http://book.cakephp.org/2.0/en/models/retrieving-your-data.html#creating-custom-find-types) for how to implement custom find types.
Specifying 'fields' for notation 'list':
- If no fields are specified, then 'id' is used for key and 'model->displayField' is used for value.
- If a single field is specified, 'id' is used for key and specified field is used for value.
- If three fields are specified, they are used (in order) for key, value and group.
- Otherwise, first and second fields are used for key and value.
Note: find(list) + database views have issues with MySQL 5.0. Try upgrading to MySQL 5.1 if you have issues with database views.
Note: find(count) has its own return values.
Parameters
- string
$type
optional 'first' - Type of find operation (all / first / count / neighbors / list / threaded)
- array
$query
optional array() - Option fields (conditions / fields / joins / limit / offset / order / page / group / callbacks)

saveAllsource public
saveAll( array $data array() , array $options array() )
Backwards compatible passthrough method for: saveMany(), validateMany(), saveAssociated() and validateAssociated()
Saves multiple individual records for a single model; Also works with a single record, as well as all its associated records.
Options
-
validate
: Set to false to disable validation, true to validate each record before saving, 'first' to validate all records before any are saved (default), or 'only' to only validate the records, but not save them. -
atomic
: If true (default), will attempt to save all records in a single transaction. Should be set to false if database/table does not support transactions. -
fieldList
: Equivalent to the $fieldList parameter in Model::save(). It should be an associate array with model name as key and array of fields as value. Eg.array( 'SomeModel' => array('field'), 'AssociatedModel' => array('field', 'otherfield') )
-
deep
: See saveMany/saveAssociated -
callbacks
: See Model::save() -
counterCache
: See Model::save()
Parameters
- array
$data
optional array() - Record data to save. This can be either a numerically-indexed array (for saving multiple records of the same type), or an array indexed by association name.
- array
$options
optional array() - Options to use when saving record data, See $options above.
Returns
mixed
If atomic: True on success, or false on failure. Otherwise: array similar to the $data array passed, but values are set to true/false depending on whether each record saved successfully.

setsource public
set( string|array|SimpleXmlElement|DomNode $one , string $two null )
This function does two things:
1. it scans the array $one for the primary key, and if that's found, it sets the current id to the value of $one[id]. For all other keys than 'id' the keys and values of $one are copied to the 'data' property of this object. 2. Returns an array with all of $one's keys and values. (Alternative indata: two strings, which are mangled to a one-item, two-dimensional array using $one for a key and $two as its value.)
Parameters
- string|array|SimpleXmlElement|DomNode
$one
- Array or string of data
- string
$two
optional null - Value string for the alternative indata method
Returns
array|null
Data with all of $one's keys and values, otherwise null.

_mergeVarssource protected
_mergeVars( array $properties , string $class , boolean $normalize true )
Merges this objects $property with the property in $class' definition. This classes value for the property will be merged on top of $class'
This provides some of the DRY magic CakePHP provides. If you want to shut it off, redefine this method as an empty function.

- The class to merge the property with.
- boolean
$normalize
optional true - Set to true to run the properties through Hash::normalize() before merging.

Parameters
- array
$properties
optional array() - An associative array containing properties and corresponding values.
_stopsource protected
_stop( integer|string $status 0 )
Stop execution of the current script. Wraps exit() making testing easier.
Parameters
- integer|string
$status
optional 0 - see http://php.net/exit for values
dispatchMethodsource public
dispatchMethod( string $method , array $params array() )
Calls a method on this object with the given parameters. Provides an OO wrapper for call_user_func_array

- Log message
- integer
$type
optional LOG_ERR - Error type constant. Defined in app/Config/core.php.
- null|string|array
$scope
optional null - The scope(s) a log message is being created in. See CakeLog::config() for more information on logging scopes.
Returns
boolean
Success of log write
requestActionsource public
requestAction( string|array $url , array $extra array() )
Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.
Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()
Passing POST and GET data
POST and GET data can be simulated in requestAction. Use $extra['url']
for GET data. The $extra['data']
parameter allows POST data simulation.
Parameters
- string|array
$url
- String or array-based URL. Unlike other URL arrays in CakePHP, this URL will not automatically handle passed and named arguments in the $url parameter.
- array
$extra
optional array() - if array includes the key "return" it sets the AutoRender to true. Can also be used to submit GET/POST data, and named/passed arguments.
Returns
mixed
Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.
toStringsource public
toString( )
Object-to-string conversion. Each class can override this method as necessary.
Returns
string
The name of this class
