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  
…  
else  
page.alert obj.errors.full\_messages.join(“\n”)  
end  
end
