Question

I’m trying to understand foobar rails code and encountered following.
There is controller A which inherits from controller B (A < B). And both of them don’t have “index” method, but B has view “app/views/B/index.rhtml.erb” which will be rendered on that action from A controller. In that view there is line:

render(:partial => "find")

But there are two files: “app/views/A/_find.rhtml.erb” and “app/views/B/_find.rjs”
And i can’t understand which would be rendered if index was called from A controller.
Further more “app/views/B/_find.rjs” has line:

page.replace_html(:contentBody, :partial => "find")

And i have no idea what is rendered here.
Any ideas?

Your application will only render the rjs files if a script was requested (usually through an AJAX request). If the user accesses your index action normally (i.e. a request for HTML using a browser), your app will render index.rhtml.erb to produce the HTML response, which will in turn render _find.rhtml.erb. If some part of your page is requesting a script, then _find.rjs will be rendered (which actually just produces a javascript response behind the scenes). In this case, _find.rjs actually uses the HTML partial _find.rhtml.erb in the call to replace_html to replace part of the page.

BTW, you seem to be using an older version of Rails as rhtml and rjs are no longer used. I’d suggest working with a newer version.
