#essence_error_messages ⇒ Object

Essence validation errors

Error messages are translated via I18n

Inside your translation file add translations like:

alchemy:
  content_validations:
    name_of_the_element:
      name_of_the_content:
        validation_error_type: Error Message

NOTE: validation_error_type has to be one of:

* blank
* taken
* invalid

Example:

de:
  alchemy:
    content_validations:
      contactform:
        email:
          invalid: 'Die Email hat nicht das richtige Format'

Error message translation fallbacks

In order to not translate every single content for every element you can provide default error messages per content name:

Example

en:
  alchemy:
    content_validations:
      fields:
        email:
          invalid: E-Mail has wrong format
          blank: E-Mail can't be blank

And even further you can provide general field agnostic error messages:

Example

en:
  alchemy:
    content_validations:
      errors:
        invalid: %{field} has wrong format
        blank: %{field} can't be blank
