I am trying to call an action within a javscript function using ajax,
but I am having some problems. I need the ajax call to return a value
and am thinking I can do this using onComplete and Ajax.Request but I
am running into some problems. This is the code I am using for the
Ajax.Request:
new Ajax.Request( ''/users/username'', {
method: ''post'',
parameters: { username: $(''new_user_username'').value},
onComplete: parseResults()
});
I have an action called username in my users controller in which I am
taking the username params passed by the Ajax.Request and seeing if it
exists in the database. I want to return true/false depending on if
it exists or not. But I am having trouble even getting the
Ajax.Request to work.
This is some of the output from the console:
Processing UsersController#username (for 192.168.1.105 at 2008-12-13
19:52:39) [POST]
Session ID:
BAh7BzoMY3NyZl9pZCIlYmNjM2YxODllZWIwMGM1NDkyMzQ0NjUyODMxODAz
ZTUiCmZsYXNoSUM6J0FjdGlvbkNvbnRyb2xsZXI6OkZsYXNoOjpGbGFzaEhh
c2h7AAY6CkB1c2VkewA=--d0d5fc597c61c2a295570ee9b118db7ba4285f3f
Parameters: {"username"=>"d",
"action"=>"username",
"controller"=>"users"}
ActionController::InvalidAuthenticityToken
(ActionController::InvalidAuthenticityToken):
Im not sure how to get around this InvalidAuthenticityToken, anyone
have any idea whats going on here. Ive been struggling with this for
a while and am somewhat new to ajax so I could use some help.

Im thinking this needs to be a ''GET'' request in order to
return a
response, but when I change the method to a GET, it calls the show
action:
Parameters: {"username"=>"f",
"action"=>"show",
"id"=>"username",
"controller"=>"users"}
Stumped...

Just use remote_function and it will generate the appropriate ajax call for you - this will make your code much less brittle to Rails changes. http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html HY On Dec 13, 8:03 pm, David <dly...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Im thinking this needs to be a ''GET'' request in order to return a > response, but when I change the method to a GET, it calls the show > action: > > Parameters: {"username"=>"f", "action"=>"show", "id"=>"username", > "controller"=>"users"} > > Stumped... > > On Dec 13, 8:01 pm, David <dly...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > I am trying to call an action within a javscript function using ajax, > > but I am having some problems.
