ActiveModel is a class to be implemented by each ORM to allow Rails to generate customized controller code.
The API has the same methods as ActiveRecord, but each method returns a string that matches the ORM API.
For example:
1 2 3 4 5 | ActiveRecord::Generators::ActiveModel.find(Foo, "params[:id]")# => "Foo.find(params[:id])"DataMapper::Generators::ActiveModel.find(Foo, "params[:id]")# => "Foo.get(params[:id])" |
On initialization, the ActiveModel accepts the instance name that will receive the calls:
1 2 | builder = ActiveRecord::Generators::ActiveModel.new "@foo"builder.save # => "@foo.save" |
The only exception in ActiveModel for ActiveRecord is the use of self.build instead of self.new.
