Ruby on Rails 4.1 - Random SWF backgrounds in layout

Hi Everyone, this is my first post on Ruby on Rails, I’ve managed to get
up
and running with Rails 4.1 on FreeBSD with Nginx and Ruby 2.1.1.

My issue is this:

I have a folder located at /public/swf/ that contains numerous swf files
I
want to load as a background for every page of my site. I’ve
successfully
created a controller with a randomize method and a corresponding view
that
loads the backgrounds randomly. The problem I’m having a bit of trouble
with now is getting the output of /background/randomize.html.erb and
putting that output into the application layout so the backgrounds load
on
every page. My HTML/CSS is just fine, however I can’t seem to include
that
in the application view.

Would I be using the render method, content_for, or capture do for
taking
the raw parsed HTML output of background/randomize and putting it in the
application layout?

I would rename randomize.html.erb as a partial and render it in the
application layout. If you haven’t worked with partials, refer to the

Thanks! So I renamed /views/background/randomize.html.erb to
/views/background/_randomize.html.erb and changed the method name in the
background controller to _randomize as well. I put <%= render :partial
=>
“background/_randomize” %> in application.html.erb.

Some things work, some things don’t. So my randomize method simply sets
@swf_bg to a random file in the public folder and then I put <%= @swf_bg
%>
in the _randomize.html.erb view. This is displayed properly when I go to
/background/_randomize.html.erb, but when I go to the index of my site
it’s
not including the @swf_bg variable that displays correctly when I go to
/background/_randomize

it’s including the code from _randomize.hml.erb in my main page like:
instead of , but
when
I visit /background/_randomize in my browser it works fine.

I probably should have anticipated that would be an issue. Partials are
not templates, in fact, they are presumed to execute in the same
controller/action as the template that calls them. They don’t have
their
own corresponding actions.

I would have to test this, but I would probably define randomize as a
protected method in the applications controller (and thus, would be
inherited by all other controllers). I would then execute it as a
before_action for those controller/actions that need it. I’d be
interested
in other suggestions on handling this. I’m not positive this would
work,
but I think that this would then work in the context of your partial.
