+
+          attr_reader :name
+          validates_presence_of :name, on: [:verify, :approve]

+
+        person = Person.new
+        person.valid?                           # => true
+        person.valid?(:verify)                  # => false
+        person.errors.full_messages_for(:name)  # => ["Name can't be blank"]
+        person.valid?(:approve)                 # => false
+        person.errors.full_messages_for(:name)  # => ["Name can't be blank"]
