Hi all,
Is there a way to do validation such as if i enter a string i should
get an alert saying it is a string enter number, I can use
validates_numericality_of but its ajax form, so i can''t get the message
there.
So i am trying to validate by form field saying that
if @project.project_number!= ~ /^[0-9]+$/
render :update do |page|
page.alert(" should be a number")
end
I also tried using
if !@project.project_number.integer?
render :update do |page|
page.alert(" should be a number")
end
But it didn''t worked. Is there a way to do this??

If you do something like: logger.debug("@project.project_number: !#{@project.project_number}!") do you see: !123123124! or stuff like: !123123123 ! or other non-numbers between the "!"s? -- Michael Wang --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Naga harish Kanegolla wrote:> I am getting only the number which i entered in the form,What''s your code look like right now? Is @project.project_number coming back as a String or Fixnum or something else? You can output @project.project_number.class to see what class it is. You could try something like this: if not @project.project_number.to_s =~ /^[0-9]+$/ ... end If it''s not coming back as a String. -- Michael Wang --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I tried outputting like this puts @project.project_number.class, it gave
me the Fixnum so i tried using
if not @project.project_number.to_s =~ /^[0-9]+$/
...
end
now its taking both string and integer both into the db.
Is there anything else??

How big can the project_number get? A Fixnum is an integer that can fix in the native machine''s word. What happens when you enter in letters into the form field? Is it then coming back as a String class or is it always getting converted to a Fixnum? -- Michael Wang --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is there a way to do??Without knowing all the JavaScript, AJAX and server side code that''s involved I couldn''t tell you. Your best bet may be to do the check in JavaScript on the client side and put up an alert at that point before you submit the XMLHttpRequest (the AJAX call) to the server. -- Michael Wang --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
