Rails - Jan 2006 - AJAX to submit form, but reload the whole page

I''m using ROR 1.0 and the included prototype.js to do some AJAX stuff.

I''m using the form_remote_tag to submit a login form using AJAX.
So, any error/failed login will be displayed using AJAX. But, for 
successful login, I would want it to reload the wholepage, not just 
update the <DIV>.

How can I achieve this?

change the page with javascript.  In the :success callback of your
form_remote_tag, do something like "location.href =
''foo''"

But  what about the failure case ?  Should I set a response of HTTP to
something other than 200 in the controller?so that I can handle it via the
failure callback of the Ajax class in the javascript?

Hi Vivek

I think the solution you are looking for is what Jamis Buck teached me a few
weeks ago:
...

When I''ve needed something like this, I will typically manage things
manually. Instead of specifying the :update element, I will handle
all of that in a :complete handler by hand. The :complete handler
checks the value of a custom header (''X-What-To-Do'', for
example). If
the header is ''error'', then I update the
''ajax_div'' element with the
request.responseText data. If the header is ''ok'', then I
execute
window.location.reload(false).

Does that make sense? If not, let me know and I can post a more
detailed example.

- Jamis
...

here''s a snippet from the hypothetical RHTML file:

   <script type="text/javascript">
     function handleComplete(request) {
       var instruction =
request.getResponseHeader(''X-Instruction'')
       if(instruction == "error") {
         $(''ajax_div'').innerHTML = request.responseText
       } else {
         window.location.reload(false)
       }
     }
   </script>

   <div id="ajax_div"></div>
   <%= form_remote_tag
:complete=>''handleComplete(request)'',
        :url=>{:controller=>''matters_crud'',
               :action =>:update,
               :id => @matter} %>
     <%= render_partial ''form'' %>
     <%= submit_tag ''Edit'' %>
   </form>

Then, in your controller, you just do:

   def update
     @matter = Matter.find(params[:id])
     if @matter.update_attributes(params[:matter])
       headers[''X-Instruction''] = "ok"
       render :nothing => true
     else
       headers[''X-Instruction''] = "error"
       render :partial => ''error''
     end
   end

- Jamis
....

Hope that helps

Okada.

Hi Carlos,
Thanks for the example..Thats what I was looking for .Just one small thing.
Whats the false parameter you pass to window.location.reload(). I actually
want to do something like redirecting to the user''s homepage if the
password/username is correct.
So I suppose something like this should work.
document.href=''/matters_crud/home''

Vivek

Hi all:

I''m doing something similar to this but for an account signup 
controller.  So once the user successfully creates an account, the user 
is redirected to index.rhtml by

window.location.href = "http://localhost:3000";

I have a problem where the session hash gets deleted on the first time 
through the process, but not deleted on subsequent times.  I''d like to 
preserve session[:user_id] from a successful account creation/login, but 
it never works the first time.  I can see session[:user_id] = @user.id 
being set in irb, but after the redirect session[:user_id] = nil.  And 
as previously stated, this works when I create a new account during the 
same browser session.

Has anyone else had this problem?

Boram

I would have thought that RJS provides a much cleaner solution.

update.rjs:

if @matter.valid?
  page << ''location.reload(false);''
else
  page.replace_html ''ajax_div'', :partial =>
''error''
end
