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??

You may have other “stuff” in that variable. 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?

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??

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.

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?
When i enter in letters it is always getting converted into Fixnum, but
i want if it is character or string give an alert and if it is a number
accept that, so wat can i do now?? Is there a way to do??

If it’s a Fixnum it is an integer and you don’t need to do a pattern
match to check it. How big can the project_number get? A Fixnum is an
integer that can fix in the native machine’s word.

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.
