* )
* );
* }}}
*
* ### Possible keys in association
*
* - `className`: the classname of the model being associated to the current model.
* If you’re defining a ‘Profile belongsTo User’ relationship, the className key should equal ‘User.’
* - `foreignKey`: the name of the foreign key found in the current model. This is
* especially handy if you need to define multiple belongsTo relationships. The default
* value for this key is the underscored, singular name of the other model, suffixed with ‘_id’.
* - `conditions`: An SQL fragment used to filter related model records. It’s good
* practice to use model names in SQL fragments: “User.active = 1” is always
* better than just “active = 1.”
* - `type`: the type of the join to use in the SQL query, default is LEFT which
* may not fit your needs in all situations, INNER may be helpful when you want
* everything from your main and associated models or nothing at all!(effective
* when used with some conditions of course). (NB: type value is in lower case - i.e. left, inner)
* - `fields`: A list of fields to be retrieved when the associated model data is
* fetched. Returns all fields by default.
* - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
* - `counterCache`: If set to true the associated Model will automatically increase or
* decrease the “[singular_model_name]_count” field in the foreign table whenever you do
* a save() or delete(). If its a string then its the field name to use. The value in the
* counter field represents the number of related rows.
* - `counterScope`: Optional conditions array to use for updating counter cache field.
*
* @var array
* @link http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html#belongsto

* public $hasOne = array(
* 'Profile',
* 'Address' => array(
* 'className' => 'Address',

* }}}
*
* ### Possible keys in association
*
* - `className`: the classname of the model being associated to the current model.
* If you’re defining a ‘User hasOne Profile’ relationship, the className key should equal ‘Profile.’
* - `foreignKey`: the name of the foreign key found in the other model. This is
* especially handy if you need to define multiple hasOne relationships.
* The default value for this key is the underscored, singular name of the
* current model, suffixed with ‘_id’. In the example above it would default to 'user_id'.
* - `conditions`: An SQL fragment used to filter related model records. It’s good
* practice to use model names in SQL fragments: “Profile.approved = 1” is
* always better than just “approved = 1.”
* - `fields`: A list of fields to be retrieved when the associated model data is
* fetched. Returns all fields by default.
* - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
* - `dependent`: When the dependent key is set to true, and the model’s delete()
* method is called with the cascade parameter set to true, associated model
* records are also deleted. In this case we set it true so that deleting a
* User will also delete her associated Profile.

* {{{
* public $hasMany = array(
* 'Comment',
* 'Task' => array(
* 'className' => 'Task',
* 'foreignKey' => 'user_id'
* )
* );
* }}}
*
* ### Possible keys in association
*
* - `className`: the classname of the model being associated to the current model.
* If you’re defining a ‘User hasMany Comment’ relationship, the className key should equal ‘Comment.’
* - `foreignKey`: the name of the foreign key found in the other model. This is
* especially handy if you need to define multiple hasMany relationships. The default
* value for this key is the underscored, singular name of the actual model, suffixed with ‘_id’.
* - `conditions`: An SQL fragment used to filter related model records. It’s good
* practice to use model names in SQL fragments: “Comment.status = 1” is always
* better than just “status = 1.”
* - `fields`: A list of fields to be retrieved when the associated model data is
* fetched. Returns all fields by default.
* - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
* - `limit`: The maximum number of associated rows you want returned.
* - `offset`: The number of associated rows to skip over (given the current
* conditions and order) before fetching and associating.
* - `dependent`: When dependent is set to true, recursive model deletion is
* possible. In this example, Comment records will be deleted when their
* associated User record has been deleted.
* - `exclusive`: When exclusive is set to true, recursive model deletion does
* the delete with a deleteAll() call, instead of deleting each entity separately.
* This greatly improves performance, but may not be ideal for all circumstances.
* - `finderQuery`: A complete SQL query CakePHP can use to fetch associated model
* records. This should be used in situations that require very custom results.

* }}}
*
* ### Possible keys in association
*
* - `className`: the classname of the model being associated to the current model.
* If you're defining a ‘Recipe HABTM Tag' relationship, the className key should equal ‘Tag.'
* - `joinTable`: The name of the join table used in this association (if the
* current table doesn't adhere to the naming convention for HABTM join tables).
* - `with`: Defines the name of the model for the join table. By default CakePHP
* will auto-create a model for you. Using the example above it would be called
* RecipesTag. By using this key you can override this default name. The join
* table model can be used just like any "regular" model to access the join table directly.
* - `foreignKey`: the name of the foreign key found in the current model.
* This is especially handy if you need to define multiple HABTM relationships.
* The default value for this key is the underscored, singular name of the
* current model, suffixed with ‘_id'.
* - `associationForeignKey`: the name of the foreign key found in the other model.
* This is especially handy if you need to define multiple HABTM relationships.
* The default value for this key is the underscored, singular name of the other
* model, suffixed with ‘_id'.
* - `unique`: If true (default value) cake will first delete existing relationship
* records in the foreign keys table before inserting new ones, when updating a
* record. So existing associations need to be passed again when updating.
* - `conditions`: An SQL fragment used to filter related model records. It's good
* practice to use model names in SQL fragments: "Comment.status = 1" is always
* better than just "status = 1."
* - `fields`: A list of fields to be retrieved when the associated model data is
* fetched. Returns all fields by default.
* - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
* - `limit`: The maximum number of associated rows you want returned.
* - `offset`: The number of associated rows to skip over (given the current
* conditions and order) before fetching and associating.
* - `finderQuery`, `deleteQuery`, `insertQuery`: A complete SQL query CakePHP
* can use to fetch, delete, or create new associated model records. This should
* be used in situations that require very custom results.
