If I have:
@name = ''users''
And I want to do
@name.singularize.camelize.constantize.find(1)
It seems I cannot do so unless the constant User is already present in
ObjectSpace. Is there a dynamic way around this?
I''m embarrassed to admit this is my best idea so far:
name = @name.singularize
open( "#{ RAILS_ROOT }/tmp/cache/#{ name }.rb", ''w''
) do |f|
f.puts "class #{ name.camelize } < ActiveRecord::Base\n
set_table_name \"#{ @name }\"\nend\n"
end
require "#{ RAILS_ROOT }/tmp/cache/#{ name }.rb"
name = name.camelize.constantize
It works fine but then I have to do:
Dir.glob("#{RAILS_ROOT}/app/models/*.rb").each { |f| require f }
at the end to restore sanity to my Rails app.
I realize I can add some more checks to see if the faked model file is
already there and all, but please someone tell me there''s a better
way.

If that''s accurate, I think you want this: name = Object.const_set(@name.singularize.camelize, Class.new(ActiveRecord::Base))> Greg Donald--Greg --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
