How to show error messages in pop up or confirm screen?

I would like to show messages when the validation fails (must be number,
cant be blank, etc) but not in the main page I would like to open a pop
up or better yet put it in a confirm screen where user would read and
thereafter click ok.

Anyone could help me ?
Thanks in advance

ps: sorry for bad english

render :update do |page|
if obj.save
ā€¦
else
page.alert obj.errors.full_messages.join(ā€œ\nā€)
end
end
