ParamsReturnSource
Lazy-initialize the schema for this Model object, if it is not already manually set in the object. You can declare `protected $_schema = array(...)` to define the schema manually.

Parameters

  • mixed $field Optional. You may pass a field name to get schema information for just one field. Otherwise, an array containing all fields is returned. If `false`, the schema is reset to an empty value. If an array, field definitions contained are appended to the schema.

Returns
