# This approach will assume that when a new topic is added, you'll touch

- # ^class ^id ^updated_at

+ # The cache is thus automatically bumped whenever the project updated_at is touched.

+ # If your template cache depends on multiple sources (try to avoid this to keep things simple),
+ # you can name all these dependencies as part of an array:
+ #
+ # <% cache [ project, current_user ] do %>
+ # <b>All the topics on this project</b>
+ # <%= render project.topics %>
+ # <% end %>
+ #
+ # This will include both records as part of the cache key and updating either of them will
+ # expire the cache.
+ #
+ # ==== Template digest
+ #
+ # The template digest that's added to the cache key is computed by taking an md5 of the
+ # contents of the entire template file. This ensures that your caches will automatically
+ # expire when you change the template file.
+ #
+ # Note that the md5 is taken of the entire template file, not just what's within the
+ # cache do/end call. So it's possible that changing something outside of that call will
+ # still expire the cache.
+ #
+ # Additionally, the digestor will automatically look through your template file for
+ # explicit and implicit dependencies, and include those as part of the digest.
+ #
+ # ==== Implicit dependencies
+ #
+ # Most template dependencies can be derived from calls to render in the template itself.
+ # Here are some examples of render calls that Cache Digests knows how to decode:
+ #
+ # render partial: "comments/comment", collection: commentable.comments
+ # render "comments/comments"
+ # render 'comments/comments'
+ # render('comments/comments')
+ #
+ # render "header" => render("comments/header")
+ #
+ # render(@topic) => render("topics/topic")
+ # render(topics) => render("topics/topic")
+ # render(message.topics) => render("topics/topic")
+ #
+ # It's not possible to derive all render calls like that, though. Here are a few examples of things that can't be derived:
+ #
+ # render group_of_attachments
+ # render @project.documents.where(published: true).order('created_at')
+ #
+ # You will have to rewrite those to the explicit form:
+ #
+ # render partial: 'attachments/attachment', collection: group_of_attachments
+ # render partial: 'documents/document', collection: @project.documents.where(published: true).order('created_at')
+ #
+ # === Explicit dependencies
+ #
+ # Some times you'll have template dependencies that can't be derived at all. This is typically
+ # the case when you have template rendering that happens in helpers. Here's an example:
+ #
+ # <%= render_sortable_todolists @project.todolists %>
+ #
+ # You'll need to use a special comment format to call those out:
+ #
+ # <%# Template Dependency: todolists/todolist %>
+ # <%= render_sortable_todolists @project.todolists %>
+ #
+ # The pattern used to match these is /# Template Dependency: ([^ ]+)/, so it's important that you type it out just so.
+ # You can only declare one template dependency per line.
+ #
+ # === External dependencies
+ #
+ # If you use a helper method, for example, inside of a cached block and you then update that helper,
+ # you'll have to bump the cache as well. It doesn't really matter how you do it, but the md5 of the template file
+ # must change. One recommendation is to simply be explicit in a comment, like:
+ #
+ # <%# Helper Dependency Updated: May 6, 2012 at 6pm %>
+ # <%= some_helper_method(person) %>
+ #
+ # Now all you'll have to do is change that timestamp when the helper method changes.
