Instance Method Details

#mass_assign(attributes) ⇒ `Object`

Sends all the attributes in the attribute hash to the appropriate attribute writer. This is a way to circumvent the normal attribute protection on Rails models.

Example:

user.mass_assign(:username => 'Manfred', :password => 'very secret')

Instead of:

user.username = 'Manfred'
user.password = 'very secret'
