find() 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' => 1,
  '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)

Returns

array|null
Array of records, or Null on failure.

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.

set() public ¶

set( string|array|SimpleXmlElement|DomNode $one , string $two = null )

This function does two things:

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.
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.

Returns

boolean
True if there are no errors

_mergeVars() 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.

Parameters

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

_set() protected ¶

_set( array $properties = array() )

Allows setting of multiple properties of the object in a single line of code. Will only set properties that are part of a class declaration.

Parameters

array $properties optional array(): An associative array containing properties and corresponding values.

_stop() 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

dispatchMethod() 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

Parameters

string $method: Name of the method to call
array $params optional array(): Parameter list to use when calling $method

Returns

mixed
Returns the result of the method call

log() public ¶

log( string $msg , integer $type = LOG_ERR , null|string|array $scope = null )

Convenience method to write a message to CakeLog. See CakeLog::write() for more information on writing to logs.

Parameters

string $msg: 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

requestAction() 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.

toString() public ¶

toString( )

CakeObject-to-string conversion. Each class can override this method as necessary.

Returns

string
The name of this class
