You may not have write access to your production file system. Generally we want our Rails server to tell our CDN and browser that the asset is "public", that means any cache can store the request. Next you'll need to sign up for a CDN service from a cloud hosting provider. You can also set this value through an environment variable to make running a staging copy of your site easier: For example, if each supplier in your application has only one account, you'd declare the supplier model like this: Development mode will work as expected. A common pattern for using a CDN is to set your production application as the "origin" server. You may be doing frequent deploys that do not include asset changes. For example, in an application containing authors and books, the author model could be declared like this: You can do this by configuring Rails to set your CDN as the asset host instead of using a relative path. Once you have configured your server and your CDN when you serve a webpage that has an asset: For example, if a document has many sections, and a section has many paragraphs, you may sometimes want to get a simple collection of all paragraphs in the document. This association indicates that the declaring model can be matched with zero or more instances of another model by proceeding through a third model. If the CDN does not have a copy it will try to find it at the "origin" example. For example, it makes more sense to say that a supplier owns an account than that an account owns a supplier. If some that existed previously are now missing, then their join rows are automatically deleted. Local compilation allows you to commit the compiled files into source control, and deploy as normal. For example, you might have a picture model that belongs to either an employee model or a product model. There are several reasons why you might want to precompile your assets locally. Now that you have configured your CDN server, you need to tell browsers to use your CDN to grab assets instead of your Rails server directly. This way you don't have to ever manually invalidate any items in your cache. To make this work, you need to declare both a foreign key column and a type column in the model that declares the polymorphic interface: In this case, the column definition might look like this: For example, if you assign: You can request the headers from both your server and your CDN to verify they are the same: Rails offers two different ways to declare a many-to-many relationship between models. If the association name is wrongly pluralized, then the inferred class will be wrongly pluralized too.
