class method
self.new
Ruby on Rails 5.0.7.2
Since v4.0.13Signature
self.new(attributes = nil)New objects can be instantiated as either empty (pass no construction parameter) or pre-set with attributes but not yet saved (pass a hash with key names matching the associated table column names). In both instances, valid attribute keys are determined by the column names of the associated table – hence you can’t have attributes that aren’t part of the table columns.
Example:
# Instantiates a single new object
User.new(first_name: 'Jamie')
Parameters
-
attributesopt = nil
