Everything works fine except I cannot figure out how to amend my code such that: A. When the form is first

Hi guys, hoping someone can give me a pointer with this? I have a Javascript variable that I''m updating dynamically as a user interacts with the page. I want the user to be able to save it''s value at any time along with some text data in a pop-up form, so the best way I can think of is to pass it through the params hash without writing it into the form.

hello. i just checked Chad Fowler''s post "20 Rails Development No-No''s" and one guideline caught my attention. it says: "Nothing that looks at all like SQL should go into a controller, view, or helper." it really came as a surprise to me as Rails itself seems to go against such practice by its AR ''conditions'' option, which most of the times

Hi, Why is cache_sweeper not a documented method? I was pretty sure it used to be, but I could be wrong. I can''t seem to find any information on it anymore in the online docs.

Hi, AFAIK after_create is called after_save if the entry does not exist in the DB. Is there a way to tell if a specific model is new or not in after_save? I have to do something like: def after_save add_to_history ''save'' end def after_create add_to_history ''create'' end However after_save is called when creating too. -- cheers, M.

Hi all. I am actually using ActiveRecord outside of Rails but I don''t see that it matters for this question. I want to automatically create a registration entry when I add a new user to my application.

Hi all I''m moving to using Machinist in my rspec tests and am having a problem with an after_create callback method that i need to stub out. It seems like calling ClassName.make will trigger this callback before i''ve had the chance to stub it. Can i stub it in my blueprint for that class? Or, can i stub the method for all instances of the class before i call ClassName.make?

I have a really good RoR 2.X book that I have read and reread a few times and starting to try to apply what I read...
