As in Rails as Tony said I use in my apps this kind of code:
def new
@model = Model.new
render
end
def create
@model = Model.new(params[model])
begin
@model.save
redirect url(:next), :message => {:success => 'You did it!'}
rescue Sequel::ValidationFailed
render :new
end
end
In new you can have:
<%= error_messages_for :model %>
..
..
