You are most likely going to have models. Those models are your
business objects. In your case you're not going to be talking to a
database, so the conventional "model" that is backed by a database
will not be needed.
However, a Model in Rails can just be a simple Ruby class. Typically
you'd have data models that did the RPC calls, so that the controllers
interacted with them. The models then do the RPC calls to your
backend, keeping each piece of code separated and easy to test. For
example, say you were making a new front-end to Twitter. A skeleton
model might look like this:
class Twitter
def initialize(user, password)
@user = user
@password = password
end
# returns timeline for the user
def posts
end
# creates a new post
def post(message)
....
end
private
end
Heck, you might even break this down farther and have a Post model,
which you'd use to hold the Post you retrieved from Twitter, or even
to have the Post class handle the creation of posts.
class Post
attr_accessor :message, :username, :posted_at
end
The basic idea here is that you'd use models to encapsulate your
logic, and controllers just to route requests around and show views.
So, you'll have "models". just not ActiveRecord models.
