frozen?() Instance Public methods Returns true if the attributes hash has been frozen.

freeze() Instance Public methods Clone and freeze the attributes hash such that associations are still accessible, even on destroyed records, but cloned models will not be frozen.

eql?(comparison_object) Instance Public methods Alias for: ==

encode_with(coder) Instance Public methods Populate coder with attributes about this record that should be serialized. The structure of coder defined in this method is guaranteed to match the structure of coder passed to the init_with method. Example: class Post < ActiveRecord::Base end coder = {} Post.new.encode_with(coder) coder # => {"attributes" => {"id" => nil, ... }}

dup Instance Public methods Duped objects have no id assigned and are treated as new records. Note that this is a âshallowâ copy as it copies the object's attributes only, not its associations. The extent of a âdeepâ copy is application specific and is therefore left to the application to implement according to its need. The dup method does not preserve the timestamps (created|updated)_(at|on).

connection_handler() Instance Public methods

clone Instance Public methods Identical to Ruby's clone method. This is a âshallowâ copy. Be warned that your attributes are not copied. That means that modifying attributes of the clone will modify the original, since they will both point to the same attributes hash. If you need a copy of your attributes hash, please use the dup method. user = User.first new_user = user.clone user.name # => "Bob" new_user.name = "Joe" user.name # => "Joe" user.

==(comparison_object) Instance Public methods Returns true if comparison_object is the same exact object, or comparison_object is of the same type and self has an ID and it is equal to comparison_object.id. Note that new records are different from any other record by definition, unless the other record is the receiver itself. Besides, if you fetch existing records with select and leave the ID out, you're on your own, this predicate will return false. Note also that destroying a rec

<=>(other_object) Instance Public methods Allows sort on objects

new(attributes = nil, options = {}) Class Public methods 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 â hence you can't have attributes that aren't part of the table columns. Example: # Instantiates a single new object User.new(first
