Folks: I''ve uplaoded the B1.05 version of AWDwR. It fixes a number of reported errata (and a few that weren''t reported :), and adds two significant changes: 1. It now uses the new Active Record decimal -> BigDecimal conversion. I''ve personally been waiting for this for a long time, and I''m really happy it''s now part of core. However,

Hi all, I am trying to patch a small rails app into a large system we have at our company. The legacy has a large database that naturally does not match the Rails conventions, but this has not been a serious problem thanks to rails flexibility.

Or even going as far as trying to save the object but failing from the model''s

Just a quick silly question , are form_helpers actually helper.rb files ? Stuart

Hi, I''m trying to follow the "AWDR" example of storing certain types of numbers (in my case, percentages not money) as integers in the database. I understand from the Depot application how to format the output to have 2 places (or n places for that matter) decimal. Now, I"m wondering about the input. It''s more natural for people to enter numbers as

I have a table of employees with the fields "last_name" and "first_name". I would like to populate a collection select so that what the user sees in the drop-down is "Last Name, First Name". So far, the only way I have figured out to do this is by using "find_by_sql" in my model, like so: @employees.find_by_sql("SELECT id, concat(last_name,

It''s in two parts, but I think the solution is somewhat related: I have Recipe and Category model related by HABTM. I would like to 1.) Validate the *number* of categories associated with a recipe, say a minimum of 1 and a max of 3. (So validates_associated will not

I have just some vague and thus probably wrong ideas about when to use model() in controllers, and by now I err on being redundant. I don''t post them here to avoid leaving anything that may be false in the archives. Can anyone explain exactly in which cases one should use model()? -- fxn

Hello, I''m seeking a book on rails deployment (I think a general deployment on nix book can helps too) I need in depth information about Apache, FastCGI, (LightTPD maybe). I was thinking always I know what a web server is! but when I think more deeply about it (after reading Capistrano doc) it seems I need more info about app, web and db servers. stuff like how to config the app server

Is it possible? It is mentioned in AWDWR but I cannot find that option in the MySQL documentation. I can dump the whole db or just the structure, but I''d like to be able to dump just the contents. bruce

I''m a real Newb; just bought AWDwR and using it with Win2000 - it took me ages, and only after reading Curt Hibbs Rolling with Ruby, to realise that I needed to use Cmd.exe before using AWDwR''s dave> instructions.

When developing applications, Webrick will automatically reload controllers, models, etc. if the source changes. For obvious reasons, it doesn''t do this for plugins, which makes it a pain to develop said plugins. I was hoping Mongrel might have some facility to say "watch this directory too and reload any changes". Obviously, re-init''ing all plugins would be

Hello, My main application layout, app/views/layout/application.rhtml looks like this: something render partial_1 something else render partial_2 something else render partial_3 The partials are not really doing anything, i use them to keep the layout modular (i.e . to have ~30 lines instead of 200).
