# 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.
#
class ActiveModel
attr_reader :name
def initialize(name)
@name = name
end
# GET index
def self.all(klass)
"#{klass}.all"
end
# GET show
# GET edit
# PUT update
# DELETE destroy
def self.find(klass, params=nil)
"#{klass}.find(#{params})"
end
# GET new
# POST create
def self.build(klass, params=nil)
if params
"#{klass}.new(#{params})"
else
"#{klass}.new"
end
end
# POST create
def save
"#{name}.save"
end
# PUT update
def update_attributes(params=nil)
"#{name}.update_attributes(#{params})"
end
# POST create
# PUT update
def errors
"#{name}.errors"
end
# DELETE destroy
def destroy
"#{name}.destroy"
end
end
