Hi,
I''m new to fragment caching, and was wondering the best way to do it
for
a dynamically generated page. I have been working off of the "Agile Web
Development with Rails" book, but it''s rather brief on fragment
caching.
For example, suppose you have a list of manufacturers and each of which
has many products. Here is how I would implement the caching, but I''m
not clear if it will work, or if there''s a cleaner, less clunky of
doing
it:
Product Controller:
def list
@mid = params[:manufacturer_id]
if @mid.nil?
@mid = "all"
unless read_fragment(:action => ''list'', :mid =>
"all")
@products = Product.find(:all)
end
else
unless read_fragment(;action => ''list'', :mid =>
@mid.to_s)
@products = Product.find_by_manufacturer_id(@mid)
end
end
end
View (list.rhtml)
<% cache(:action =>''list'', :mid => @mid) do %>
<ul>
<% for p in @products %>
<li><%= p.name %></li>
<% end %>
</ul>
<% end >
Any suggestions or advice on a better way to to go about doing this
would be much appreciated. Thanks.

Jay, I''m fairly new to Rails too, but the code looks fine. There are no doubt more Ruby ways of writing it. One thing. Doesn''t the cache need to be expired when a manufacture updates?

Does anyone have any recommendations for production-ready plugins that make this simpler? I''ve been bouncing around the various plugin sites, and haven''t found one that seems to make this as easy as it should be. One promising one is this one, but I don''t think I would call it production-ready, as it looks like it was released *yesterday*: http://blog.overlay.tv/articles/2007/06/16/intelligent_fragment_cache -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
