TopModel is a Rails 4 compatible In-Memory Object-Relational mapper using ActiveModel
This gem is based on topmodel by Alex Maccaw (maccman). It includes some fixes and is updated to be compatible with Rails 4.
Primarily developed for Bowline applications. http://github.com/maccman/bowline
Supports:
- Serialisation
- Validations
- Callbacks
- Dirty (Changes)
- Ruby Marshalling to disk
- Redis
Examples:
require "topmodel"
class Test < TopModel::Base
end
t = Test.new
t.name = "foo"
t.save #=> true
Test.all
Test.first
Test.last
Test.find_by_name('foo)
You can use a random ID rather than the object ID:
class Test < TopModel::Base
include TopModel::RandomID
end
t = Test.create(:name => "test")
t.id #=> "7ee935377bb4aecc54ad4f9126"
You can marshal objects to disk on startup/shutdown
class Test < TopModel::Base
include TopModel::Marshal::Model
end
TopModel::Marshal.path = "dump.db"
TopModel::Marshal.load
at_exit {
TopModel::Marshal.dump
}
You can use Redis, you need the Redis gem installed:
require "redis"
class Test < TopModel::Base
include TopModel::Redis::Model
attributes :name
indexes :name
end
Test.find_or_create_by_name("foo")
