Am having real probs trying to use Ajax with my Rails app. I have set up
a test as
follows:
in javascript file:
window.onload = function() {
$(''#test'').bind(''ajax:success'',
function() {
alert("success");
};
}
in view:
<%= link_to "test", { :action => :getDiagram }, :remote =>
true, :id =>
"test" %>
in controller:
def getDiagram
end
Now I know this looks odd with the empty controller action, but I would
expect this code to just show a popup window with ''success''
and leave
the current page loaded when the link is clicked? Instead i get the
missing template message like its trying to load a page synchronously
rather than using ajax?
Can anyone get my test to work? Do I need to upgrade or add a gem file?
Thanks in advance
Jason

It is probably make more sense to test with Json response using respond_to :json respond_with { :status => ''okay'' } -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

When setting render :nothing => true it just renders a blank template which is not what i want. The ajax:success event is not firing either -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

dude, you miss a lot.
in *.js.erb
blablabla, looks fine
in controler
you miss format.js
in router
you miss
resource contoler_name do
get: :getDiagram on :member # or post or whatever, that will be your
method name in link_to tag
end
in erb tamplate
<%= link_to "Button", controler_action_path, method: get, remote:
true =>
that all, you should try it now, and should works
