Multiple private methods allowing StateGate::Builder to generate attribute setter methods for transition validation.

• initializing the attribute with Class.new :

  Klass.new(status: :active)  #=> ArgumentError
  

• initializing the attribute with Class.create :

  Klass.create(status: :active)  #=> ArgumentError
  

• initializing the attribute with Class.create! :

  Klass.create!(status: :active)  #=> ArgumentError
  

• setting the attribute with attr= :

  .status = :active    #=> :active
  .status = :archived  #=> ArgumentError
  

• setting the attribute with [:attr]= :

  [:status] = :active    #=> :active
  [:status] = :archived  #=> ArgumentError
  

• setting the attribute with attributes= :

  .attrubutes = {status: :active}    #=> :active
  .attributes = {status: :archived } #=> ArgumentError
  

• setting the attribute with assign_attributes :

  .assign_attrubutes(status: :active)    #=> :active
  .assign_attributes(status: :archived)  #=> ArgumentError
  

• updating the attribute with Class.update :

  Klass.update(instance.id, status: :active)    #=> :active
  Klass.update(instance.id, status: :archived)  #=> ArgumentError
  

• updating the attribute with .update :

  .update(status: :active)    #=> :active
  .update(status: :archived)  #=> ArgumentError
  

• updating the attribute with .update_column :

  .update_column(:status, :active)    #=> :active
  .update_column(:status, :archived)  #=> ArgumentError
  

• updating the attribute with .update_columns :

  .update_columns(status: :active)    #=> :active
  .update_columns(status: :archived)  #=> ArgumentError
  

• updating the attribute with .write_attribute :

  .write_attribute(:status, :active)    #=> :active
  .write_attribute(:status, :archived)  #=> ArgumentError
  

| Forcing a change

To force a status change that would otherwise be prohibited, preceed the new state with force_ :

.status = :archived         #=> ArgumentError
.status = :force_archived   #=> :archived
