I had exactly this case recently, because my application is in Croatian
language, so it was never good to have the model name automatically in the
error messages (because it's rarely convenient for languages other than
English), and I didn't want to write `Sequel.lit` all the time.
So, because my app is an API, and I wanted to raise custom validation
errors so that my application can catch them easily and display as JSON, I
did something like this:
module Utils
module_function
def valid!(object)
if object.errors.any?
errors = object.errors.flat_map { |column, messages| messages } #
<=== this part
raise MyCustomValidationError, errors
end
end
end
I'm sure you can do something similar by overriding
`Sequel::Model::Errors#full_messages`, or by using it in your helper method
for displaying the errors.
