I have an action email in my controller of application running on www.example.com

where my another application receives the request and I am able to
save the data in js format. But I want to send back the
acknowledgement to www.example.com and replace the html using rjs
template. Here are some code for you reference:
email.html.erb called on www.example.com
<div id="div_content">
<%= form_for(@user, :url => "http://data.example.com/
mail", :remote => true) do |f| %>
<%= f.label :email %>
<%= f.text_field :email%>
<% end %>
</div>
email action of application on : data.example.com/email -
def email
@user = User.create(params[:user])
respond_to do |format|
if @user.save!
format.html
{ redirect_to(user_page_path(@user.vip_id), :notice => 'Thank you!
You are now on our priority list.') }
format.js
else
format.html { render :text => "user can not be saved at this
moment!"}
end
end
end
email.js.rjs called on www.data.example.com/email
page.replace_html :div_content, :partial => "show", :object => @user
I can see in my log that request comes all the way from one domain
to sub domain and even action gets triggered but, I can not get the
response back to the main domain. So, is there any way to send a
callback to main domain. I just want to reflect changes there at the
form which is inside div_content div and want to replace with
content of _show.html.erb which I have on my sub domain.
If you're trying to do all this in JavaScript, you're going to run
smack into the Same Origin Policy. Unless you use a proxy on www.example.com
, you can't update the page using data requested from
data.example.com, or even www.example.com:2020 -- subdomain and port
must match. More here: http://en.wikipedia.org/wiki/Same_origin_policy
