What do you mean for 'domain' methods? Do you mean validations, etc? They
can be implemented; the model could be a sort of "struct on steroids"...
something like this:
module ActiveRecord
class Struct < ::Struct
def self.find
end
def self.all
end
# other various implementations
end
class StructFor
def [](table_name)
# retrieve table column names
ActiveRecord:::Struct.new(*table_column_names)
end
end
end
model:
class User < ActiveRecord::StructFor[:users] # this returns
ActiveRStruct.new(:firstname, :lastname, :active)
def before_save
# ...
end
end
