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:
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:
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.
