#errors ⇒ Object

Return the ValidationErrors

end

#valid?(context = :default) ⇒ Boolean

Check if a resource is valid in a given context

Returns:

end

#valid_for_default? ⇒ Boolean

Alias for valid?(:default)

Returns:

  • (Boolean)

# File 'lib/dm-validations.rb', line 131

def valid_for_default?
  valid?(:default)
end

#validatable? ⇒ Boolean

Mark this resource as validatable. When we validate associations of a resource we can check if they respond to validatable? before trying to recursivly validate them

Returns:

  • (Boolean)

# File 'lib/dm-validations.rb', line 125

def validatable?
  true
end

#validation_property(field_name) ⇒ Object

Get the corresponding Resource property, if it exists.
