Hi everyone, So I have this app that I built which originally only needed to support one site, and it runs quite fast. Now I added the ability to run multiple sites on the same app, similar to how wordpress.com and Posterous run multiple different sites with different domains and content on the same software. However, since adding a Site model and it's associations, the app is much, much slower. Using EXPLAIN I can see that the additional JOINs are causing bottlenecks, and I'm having trouble figuring out what the best indexing and lookup strategy is. Download objects can appear in 1 or more sites.
The models go like this: class Site < ActiveRecord::Base has_and_belongs_to_many :downloads end class Download < ActiveRecord::Base acts_as_taggable has_permalink :title belongs_to :category has_and_belongs_to_many :sites end require 'ancestry' # uses ancestry gem for hierarchies https://github.com/stefankroes/ancestry class Category < ActiveRecord::Base has_permalink :name, :permalink has_ancestry has_many :downloads def to_s path.map { |cat| cat.name }.join(" > ") end end # application_controller.rb def set_site @site = Site.first(:conditions => {:domain => request.domain}) # do some other stuff like set up some site-wide titles, logos, etc. end Also, I want to be able to show only the categories that contain active download objects for a particular site. Can anyone help me figure out what the best way to go about this is? Thanks! Avishai -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
