def ==(other)
  return false unless self.class == other.class
  return false unless __raw_model == other.__raw_model # steep:ignore

  true
end

#__raw_model ⇒ Object

Returns a model instance of raw, but it should be noted that application developers are not expected to use this interface.

Returns:

  • (Object) —

    raw model instance

def __raw_model = model

#destroy_context? ⇒ Boolean

Determines whether to save or delete the target object. Depends on the ‘destroy` value of the InnerModel object initialization option.

On the other hand, there are values ‘mark_for_destruction` and `marked_for_destruction?` in ActiveRecord. However, these values are not substituted here. These values only work if the `autosave` option is enabled for the parent model, and are not appropriate for other cases.

Returns:

  • (Boolean) —

    returns true on destroy, false on save.

def destroy_context?
  d = destroy_context_type
  if d.is_a?(Proc)
    if d.arity == 0
      # @type var d: ^() -> bool
      !!d.call
    else
      # @type var d: ^(_ARLike) -> bool
      !!d.call(model)

#invalid? ⇒ Boolean

Returns:

  • (Boolean)

# File 'lib/active_record_compose/inner_model.rb', line 53

def invalid? = destroy_context? ? false : model.invalid?

#save ⇒ Boolean

Execute save or destroy. Returns true on success, false on failure. Whether save or destroy is executed depends on the value of ‘#destroy_context?`.

  • (Boolean) —

    returns true on success, false on failure.

def save = destroy_context? ? model.destroy : model.save

#save! ⇒ Object

Execute save or destroy. Unlike #save, an exception is raises on failure. Whether save or destroy is executed depends on the value of ‘#destroy_context?`.

# File 'lib/active_record_compose/inner_model.rb', line 50

def save! = destroy_context? ? model.destroy! : model.save!

#valid? ⇒ Boolean
