In two weeks, Dave Thomas will be in Pasadena doing a three-day Rails workshop. I''m about to sign up for it. I figure three intense days with Dave and a few dozen other Rails developers will produce huge learning leaps for me. Then it occurred to me that it might be useful to ask the list if anyone has attended one of these workshops before and, if so, how valuable you found

It seems Rails sessions by default only last, well, a browsing session. If the Rails app keeps track of logged-in state by sessions, that state doesn''t survive restarting the browser. How best to change this behaviour, to make the session cookie live forever, or at least beyond browser restarts? It was suggested to me on IRC to combine sessions with code to generate a unique id and

As a long-time author of computer books, fairly experienced MVC/OO thinker/coder, and recent Rails convert, it is probably not surprising that my midnight ruminations occasionally lead me to wonder if a Rails book might not be an interesting undertaking. But I know there are some great titles out there already and undoubtedly dozens more in the works. I''m interested in writing

Hi, My application has a table of People that has information about them, and I want to have a subset of those people as Users - people that can login to the application. What is the best way to do this? Add columns to People that only Users would use? I''ve read the threads on single table inheritance, but it seemed a little bit wasteful: 10,000 people vs 50 users For those more

Back in the horse-and-buggy days when I was cutting my OO eye teeth on Smalltalk, we had a LOT of conversations about the biggest problem dealing with a large and growing set of classes and methods in the Smalltalk image. It became clear that most, if not all, successful Smalltalk coders spent a lot of their time code-shopping, i.e., looking for a class or method that did something they

I needed to format numbers with commas to make it more human readable. Here''s how I did it. def commify(number) c = { :value => "", :length => 0 } r = number.to_s.reverse.split("").inject(c) do |t, e| iv, il = t[:value], t[:length] iv += '','' if il % 3 == 0 && il != 0 { :value => iv + e, :length =>

Hi ! I was talking to a seasider and he asked me if it was easy to do the following thing using rails : 1) ask a number to the user 2) ask a second number 3) give the addition of the two number and a link to be able to replay All these things have to be done in one controller and one action, there is no need for verification and other stuff. I tried but I''ve got some problems

Just tried the first AJAX example in the rails book (p.391-392, the ''word guessing'' thing), and the AJAX partial used seems to render as a full page. I''m not sure whether it''s a) a partial bug b) some interaction between ajax and partials c) a change since the book came out or d) pilot error I''ve checked the errata pages and it''s flagged up

I recently finished the first part of the "Agile Rails" book. But, the depot doesn''t completely work as it should. I still have 2 problems: I will explain them in 2 threads. The first one is: I can''t destroy products (I can only creat and update them). When I try to delete a product --> http://localhost:3001/admin/destroy/3 I get this error message:

Hi Railers, I have a scenario to figure out that I''ve never yet come to a good answer for, and I''m hoping some of you can shed some light. The owner of website I built a while back (in PHP) would like to extend the capabilities of the website to be fully CMS driven, with multiple language versions (French, Spanish etc.) available in future. At the moment, a few parts of

What is the most elegant way to save new one-many associations? order = Order.new(:name => "My Order") order.line_items << LineItem.new(:product_id => 1, :quantity => 2) order.line_items << LineItem.new(:product_id => 2, :quantity => 5) order.save The above - which is by far the most elegant way of putting it - doesn''t work for me - the line_items

I am following the instructions on Agile Web Development with Rails book "Iteratio E1: Capturing an Order" section. When I run the migrations I get the following error. rake db:migrate (in /Users/balaparanj/work/depot) -- execute("alter table line_items \n add constraint fk_line_item_products \n foreign key (product_id) references products(id)") rake

anyone can explain me why in the Agile Depot Tutorial application they use i.product_id to find if a product already exist in the cart, because the cart contains items, each of them references a product. I tried i.product_id like in the tutorial and i.product.i all of these 2 notation works , but i find the second seems more clean??? isn''t it. Any explanation will be fine Regards

Hi Folks! I''m new in the forum and i have a doubt. The button back function with the Ajax on Rails? tks. -- Posted via http://www.ruby-forum.com/.

Thank you for the comments on conditional replacements. I now have another oddity to deal with. When adding products to the session cart I am not able to have the count incremented if the product has already been selected, rather another item is added to the cart. I copied the code from the book as carefully as I could and could find no error but to be sure I then cut and pasted the code

I am curious what you find is good and bad MVC design. Let''s use the find and find_by_sql methods as examples. Currently I have these spread out all over the place... View: here I have some find methods when I am for example populating a select list with choices in a form. Controller: here I have the simpler find methods. Model: here I have the more complicated find methods (usually

Hi all, I''ve a model class Toto in the model directory.

This is a newbie question, I have a class which is not derived from ActionController or ActiveRecord but I want to use logging, I tried require but still logging does not work - This class is located in a file in "model" directory. ------------------------------------ require ''logger'' class Cart def add_product(product) logger.info("Searching for product

I want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease. However as an exercise to see how much I had understood, I thought I would attempt to modify the example a bit and add a Quantity field to the store index so as to pass that value into the cart. I have extended the
