Apologies for the self-promotion, but some of the Rails newbies out there may be interested in knowing that our beginner''s Rails book is now available as a free PDF (the full thing, not just a sample). http://rails.sitepoint.com/ Personally I think it''s the best beginner''s Rails book out there, but of course my bias is going to be questionable as I edited the thing. The offer is good for 60 days. Cheers Matt --~--~---------~--~----~------------~-------~--~----~ You received this message because y...

Can anyone recommend good books, online tutorials, or any other learning materials for Javascript - specifically Object Oriented Programming using JS? I want the rest of my dev team to be able to help me code in JS, specifically using prototype and scriptaculous. I''ve been using JS for so long, and I kinda "grew up" on OOP programming but my whole team is Coldfusion

I was reading this article a while back http://www.sitepoint.com/blogs/2008/06/06/did-rails-sink-twitter/ and it got me thinking. If I wanted to set up my app so that each user has his/her own table, how would I go about doing that? "create_table :users" just creates a table in the database for a list of all the users (which I guess I''d...

Hi, I''m building an application which is going to require quite fine grained access control. Deciding if a user is allowed to access an action will probably require checking quite number of different rules, so a simple role-based system won''t be flexible enough. The approach I think I will try first is, if it''s possible, to ignore permission issues inside the

You could also check out the following tutorials. I found these pretty helpful. SitePoint Articles: http://www.sitepoint.com/print/oriented-programming-1 http://www.sitepoint.com/print/oriented-programming-2 Thank you, Mandy.

...I take it that everyone serious about using Prototype & Co. already has Christophe''s (Porteneuve) Prototype and Script.aculo.us book. Apart from that, I''d like to point out two new, library-agnostic books: Cameron Adams and several others The Art & Science of JavaScript Sitepoint 2008 http://www.sitepoint.com/books/jsdesign1/ (excerpt: http://www.sitepoint.com/print/art-science-javascript) The title is quite a mouthful ("science"?). From my limited perspective this is currently the only book that really touches on advanced topics. I particularly recommend the c...

What''s the easiest or best way to determine the screen size from within a controller or view in Rails? My "divs" look great at 1280x800, but not so hot on 800x600. I want to dynamically alter the layout based on the resolution. Any hints regarding screen size or alternate ways of handling this issue would be appreciated.

I''m a beginner. I''ve done the apple tutorial, Agile ROR (the depot app, I stopped after that, a little to advanced with no base knowledge of Ruby), Why''s guide and my copy of Chris Pine''s book today. After Pine, I''m going to buy either the Wrox book or Ruby for Rails book. I did a search and there''s not too much on the Wrox book (Holzner)

Hi, I am in a situation where I am going to have to rewrite a working Ruby on Rails application in CakePHP with PHP5. I have a whole bunch of specs written with rspec, and I was wondering if it would be possible to somehow use these specs to test the Models and Controllers that I am rewriting in CakePHP. I am going to be basically just exactly duplicating the Rails application, with identical

Has anyone extended Rails''s acts_as_tree to use the Modified Preorder Traversal algorithm? This is a really clever trick for optimizing access to trees stored in databases, as described lucidly in this article: http://www.sitepoint.com/article/hierarchical-data-database/2 It adds two integer fields, a "left counter" and "right counter", to each row. By updating these in the right way as rows are inserted and deleted in the tree, you can use them to reduce a lot of common tree operations -- like gett...

Hi all. I''m a new convert (or at least I want to be a convert) to Rails. I''ve got the book, have read it, done bits and pieces of the demo, and tried to apply it to a rather complicated DB I''ve got here. I''ve got a ton of questions, and before I bore everyone here, is there a dedicated forum for Rails newbies to get help? Yak -- Posted via

Hello! I have 2 table: users and buddies User: id, name, ... Buddy: id, user_id, user_buddy_id, ... So if you have 2 users 1,jack and 2,fred and fred is a buddy of jack, there is a Buddy object: id=1, user_id=1, user_buddy_id=2 I can declare only one belongs_to in Buddy and one has_many in User. And there is conflict if I had the second one (the first one is discarded) class User has_many

...ated with the foreign record''s ID, but instead is simply 0 (discovered this by looking at the tables manually). The example has two models: stories and votes. One story-->many votes relationship. The stories fixture: one: name: My shiny weblog link: http://poocs.net/ two: name: SitePoint Forums link: http://www.sitepoint.com/forums/ The votes fixture: one: story_id: one two: story_id: one three: story_id: two four: story_id: two You''d expect that ''story_id'' for two of the records in the votes table would be set to the corresponding ID for t...

Hi, I''m looking at developing a reasonably complex web application, where most of the complexity actually lays in the database and the queries I need run on it. Some "classes" or models need to consist of an assembly of several tables. It would be trivial enough for me to code these queries in SQL, but as far as I understand Rails is trying to hide the database as

Heyo! I am setting up a self-referencial habtm relationship with the users of my app. I am using Chad Fowler''s "Rails Recipes" to get me started, and everything works great with the join table "people_friends". I add friends by doing somebody.friends << somebodyelse. However, with my app, there is an approval process so my join table has columns person_id,
