Render a .js controller request as html

ajax, controller, ruby-on-rails, ruby-on-rails-3

Solution

you can force the usable formats like this :

respond_to do |format|
  format.js   { render :layout => "notice", :formats => [:html] }
  format.html { render :layout => "notice" }
end

EDIT:

What you need is some part of the document being replaced by the response. This is done by responding with a javascript that does the job:

In your controller :

respond_to do |format|
  format.js
  format.html { render :layout => "notice" }
end

In your login.js view :

$('#whatever').html('<%= escape_javascript( render :login, formats: [ :html ]) %>')

... or something similar

Problem

I have a `before_filter` in my Rails app that sends users to `login_url` if they are logged out when they submit a request (in either html or js format). I would like my `format.js` to produce an identical result to `format.html`, in the following case to render the view with the 'notice' layout. How can I do this? ``` respond_to do |format| format.js format.html{ render :layout => "notice" } end ```
