Instance Method Summary (collapse)

• - (Object) begin_validate

  Begin the associated validation.

• - (Object) exit_validate

  Exit the associated validation.

• - (Object) read_attribute_for_validation(attr)

  Overrides the default ActiveModel behaviour since we need to handle validations of relations slightly different than just calling the getter.

• - (true, false) valid?(context = nil)

  Determine if the document is valid.

• - (true, false) validated?

  Used to prevent infinite loops in associated validations.
