Rails Override Render

Is it possible to override Rails' render behavior for :html responses? I'd like to always render the same template (ignoring the magic view finding).

I'm writing a single page app, and this seems like it should be possible...basically if it's requested as :json it should render JSON, but if it's requested as :html it should pass the data on to the same view no matter what (where it will be rendered as JSON in the body).

Why not pass the JSON data as an instance variable?

controller

@json_data = whatever_model.to_json

application.html.erb

<script>
<%= @json_data %>
</script>

What if you define one single view and then after every action on every controller you render that view? Like this:

app/controllers/home_controller.rb

class HomeController < ApplicationController
  def home
  end
end

app/views/home/home.html.erb

<!-- Whatever html code and script tags here -->

app/controllers/another_controller.rb

class AnotherController < ApplicationController
  def action
    render "home/home"
  end
end

You could even define an after_filter

Edit

I tried this and it works. The after filter doesn't seem to work though.

Try to delete the yield part on your application.html.erb, then you will alway get the application.html.erb without any partials.
