Public Instance Methods

aasm_write_state(state, name=:default) click to toggle source

Writes state to the state column and persists it to the database using update_attribute (which bypasses validation)

foo = Foo.find(1)
foo.aasm.current_state # => :opened
foo.close!
foo.aasm.current_state # => :closed
Foo.find(1).aasm.current_state # => :closed

NOTE: intended to be called from an event

def aasm_write_state(state, name=:default)
  raise "Cowardly refusing to save the current CoreDataQuery context"
  aasm_write_state_without_persistence(state, name)
end
aasm_write_state_without_persistence(state, name=:default) click to toggle source

Writes state to the state column, but does not persist it to the database

foo = Foo.find(1)
foo.aasm.current_state # => :opened
foo.close
foo.aasm.current_state # => :closed
Foo.find(1).aasm.current_state # => :opened
foo.save
foo.aasm.current_state # => :closed
Foo.find(1).aasm.current_state # => :closed

Private Instance Methods

aasm_ensure_initial_state() click to toggle source

Ensures that if the aasm_state column is nil and the record is new that the initial state gets populated before validation on create

foo = Foo.new
foo.aasm_state # => nil
foo.valid?
foo.aasm_state # => "open" (where :open is the initial state)

foo = Foo.find(:first)
foo.aasm_state # => 1
foo.aasm_state = nil
foo.valid?
foo.aasm_state # => nil
