Customize error message with simple_form

Question

I\'m using the simple_form gem. I want to customize the error message displayed when a user fails validations. How can I accomplish this?

There is another solution explained here that wasn't mentioned in the answers. You can directly override the error messages from the views, in the form itself. For example:

<%= f.input :last_name,
               placeholder: 'last_name',
               error: 'This is a custom error message',
               required: true,
               class: 'form-field',
               autofocus: true,
               input_html: { autocomplete: "last_name" } %>

It is however not advised as it is not DRY, you would need to override it in every field.
