#mass_assign(new_attrs = {}) ⇒ Object

Assigns the attributes of a model from a given hash of attributes.

If the assignment mode is set to ‘:whitelist`, then only the values of keys which have a corresponding attribute definition on the model will be set. All other keys will have their values ignored.

If the assignment mode is set to ‘:carefree`, then the attributes hash will be populated with any key/values that are provided.

Parameters:

  • new_attrs (Hash) (defaults to: {})
