Hi
I would like to know the difference between writing our own class
file(or module) in lib folder and models folder (Or any other folder).
Actually what is the use of this lib folder in rails..Cant I write the
same in models folder (not inheriting from ActiveRecord class)
Thanks in advance
Sijo

It''s purely for code organisation, and Rails uses the folder names for some of it''s auto load magic. I use a library called simple_form which creates a non-ActiveRecord model for contact forms but it behaves like a model as far as Rails is concerned so I will put that class in the models folder.

Re: difference in writing a class file in lib and models folder
Lib is mostly for your own classes that don''t change much. Hence, in dev mode Theyre not reloaded. Models are. Models can be any classes, inheriting from anywhere.

After all in a truly pure sense of the MVC design pattern a model object can be as simple as the String class all the way up to a class a complex as ActiveRecord. After all, what does a String object do? It manages the interface to a set of data, which is the array of characters. It abstracts and encapsulates the storage of that set of data. So in a pure sense it is a model object. That''s the interesting thing about the MVC pattern. There is no absolutes. It all depends on the definitions and usage in particular contexts.> It''s purely for code organisation, and Rails uses the folder names for > some of it''s auto load magic.I completely agree with this. Applying MVC inside the context of Rails will make others that might want to work with you on your code happy. Typically the stuff in app/models are subclasses of ActiveRecord (or other ORM style model classes). And the lib folder is typically used for classes and modules that provide some shared behavior, whether they be "model" objects or not. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
