I've been thinking about a similar problem.
Most database mappers have three components:
1. The model instance
2. The model collection
3. The model factory
I've been considering how to represent specific model instances in
Clojure. We probably expect a model instance to:
1. Locally cache its value
2. Be able to save changes on request
3. Be able to refresh itself on request
In Clojure, this might look something like:
user=> @user
Log: Fetching data from database
User{:login "jbloggs"}
user=> @user
User{:login "jbloggs"}
user=> (refresh user)
nil
user=> @user
Log: Fetching data from database
User{:login "jbloggs"}
user=> (update user assoc :name "Joe Bloggs")
User{:login "jbloggs", :name "Joe Bloggs"}
user=> (save user)
Log: Saving data to database
User{:login "jbloggs", :name "Joe Bloggs"}
