Where would I go about placing partial files shared by more than one model? I have a page called crop.html.erb that is used for one model - Photo. Now I would like to use it for another model called User as well.
I could copy and paste the code but that's not very DRY, so I figured I would move it into a partial.
Since it's shared between two models - where would I place that partial?
Thanks!

A partial allows you to separate layout code out into a file which will be reused throughout the layout and/or multiple other layouts. For example, you might have a login form that you want to display on 10 different pages on your site.
Rendering a Partial View You can render the partial view in the parent view using the HTML helper methods: @html. Partial() , @html. RenderPartial() , and @html. RenderAction() .
Rails provides us great functionality for managing layouts in a web application. The layouts removes code duplication in view layer. You are able to slice all your application pages to blocks such as header, footer, sidebar, body and etc.
A layout defines the surroundings of an HTML page. It's the place to define a common look and feel of your final output. Layout files reside in app/views/layouts. The process involves defining a layout template and then letting the controller know that it exists and to use it.
The Rails convention is to put shared partials in /app/views/shared.

Update
Layout inheritance is now in the guides under layout and rendering Template inheritance works similarly.
Rails 3.1 and following versions implement template inheritance, so I think the correct place for shared partials is now /app/views/application/, say you are in products#index you can do the following:
-# products#index = render @products.presence || 'empty' -# /app/views/application/_empty.html.haml There are no items btw it's application because the connection is the controller inheritance, so this assumes ProductsController < ApplicationController
This way if you implement /app/views/products/_empty.html.haml that will be taken, the above is a fallback for all the missing partials, and I can't check right now, but I think even for the template itself...
Railscast: template inheritance!
