First, you can have a basic validation via JS adding to that body input the attribute required: true. That will trigger HTML5 validation if you try tu submit a empty input.
If you have your validation via ActiveRecord in your model, you need tu put specific code in your view to show the error. Are you looking for @your_record.errors ?
You can see the error messages triggered by your validation (on the model) looking at @your_record.errors.full_messages

Hi,How can I show error messages if a comment is invalid? E.g. when a comment body is empty. I add validation in the model class, and the validation itself works, but it won't show any error message. Can you please help? Many thanks!Regards,Jason
