hey guys,
I need to pass an object to a ruby method, which handles an Ajax call.
I would appreciate if you could tell me a convenient way to do so.
Here is some of my javascript for the Ajax:
function submitAjax(evt){
evt.preventDefault();
url = “<%= url_for(:controller => ‘groups’, :action => ‘search’,
:canvas => false, :only_path => false ) %>”;
form = document.getElementById(‘search_group_form’);
submitForm( form , url,‘search_team_results’);
return false;
}
I am not sure if there is a way to pass an object in the url string
above. I tried the following:
url = "<%= url_for( …, :action => ‘search’, :myobject =>
#{@myobject} …
but it didn’t work.
Thanks in advance!
maybe you can save object to session and send a flag to get the object?

Thanks a lot for the hint. The idea seems very nice. However, I can’t
get it working. I’m using the Facebooker plugin, maybe it messes up with
sessions.
in my index method of the main controller, I create the session
variable:
session[:me] = @me
then in another method I try to use print it’s contents:
print “\n” + session[:me].account_id.to_s
However, I get an error: “You have a nil object when you didn’t expect
it!”
So the variable is not preserved in the session. Am I doing something
wrong with storing/retrieving the session objects?
Thanks again!
storing whole objects in session isn’t usually a good recommendation…
the best solution would probably be to pass just the object’s id and
then retrieve it from the database/wherever in your requested action
another approach could be to serialize the object and deserialize it
at the server. however, if you just need to pass a hash or something
like that, you could use the json notation to pass the data

hmmm, ok,
but even if I try this
session[:me] = @me.account_id
and try to print it in the other method
print “\n” + session[:me].to_s + “aaa”
it only prints the “aaa”
If I try to print it in the same method, after I have added it to the
session, then it outputs the account_id… grr
How is it possible that the session is not preserved when I call its
variables in another method.
By the way, even when I stored a whole object in the session, I could
print its contents in the same method where I stored it.
any ideas

aah ok, that was one of the things I tried first.
however, I’m still not sure how I should do that syntactically.
As I mentioned in my first post, I tried to do something like:
(in the controller): @myid = “15”
Then in the javascript function, which issues the Ajax call I construct
the following url for the Ajax call:
url = "<%= url_for(:action => ‘search’, :myid => #{@myid}, canvas =>
false…
Then I get a syntax error. I am not sure how I have to pass the variable
in the Ajax url?!
And still, I am wondering why after putting a simple string into the
session, I cannot retrieve it from another method (different than the
one where I added the string)
Thank you!

Thanks for the help!
