I am new to Rails/Jquery and am really struggling.
What I want to do is change several fields in my database from null to true when a user clicks on a button (without navigating away from the current page). I know I need to use Ajax in some way or another, but am not sure how. I have been struggling for about 2 hours now and would love it if someone could even point me in the right direction.
Stackoverflow, you are my only hope.
I wrote an answer responding to a question similar to yours not long ago here. But basically what you have are 3 parts:
In your view, you will have something like
<%= button_to "Click me!", :action => "some_action", :remote => true %>
Which will send an AJAX request back to the server, in which you need to handle in your controller
def some_actoin
// Update your database here
respond_to do |format|
format.js { render 'somepartial' }
end
end
Then you will have a 'somepartial.js.erb' file that contains the code (in your case I don't know if this file needs to contain anything) that updates your DOM.
Read this for a very good explanation of AJAX and Rails3. Good luck.
