I''m studying the Agile Development with Rails book. In the chapter that first sets up the depot application (page 68), there is this bit of code from a view: <% for product in @products %> <tr> <% for column in Product.content_columns %> <td><%=h product.send(column.name) %></td> <% end %> etc... I am trying to absorb both Ruby and

Hello, Im in the process of working my way through the 2.ed of the agile book. As many of you already know, the book goes through the regular development cycle of the Depot application. I have hit a wall when they started talking about the sessions and the exact mechanics of how an item is added to the session. The code looks like this: depot/app/controllers/store_controller: def add_to_cart

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 ya, I want to add categories to the depot example in the Agile rails book. These are my thoughts: Create a new table called categories with id, title, description, and image fields.

Sorry for the long Subject line, but I couldn''t figure out what else to call it. :-) Just a quick announcement to tell you that I have worked through Chapters 6 and 7 so far of "Agile Web Development with Rails", using Ackbar/KirbyBase to develop the Depot app instead of MySQL.

I''m working on building the shopping cart in the Depot tutorial in the Agile Web Development book. I''m at the part (about page 80) where you build the ability to add items to the cart. I''m able to get to /store/display_cart/ and it seems items are being added, but if I just click on a link to add an item (/store/add_to_cart/2) it gives me this: NoMethodError in

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 *, In an attempt to go back to the drawing board and learn RoR some more - I have built the depot application from the agile book. After finishing I tried to create a user for the admin section, however when ever I go to: http://localhost:3000/login/add_user It redirects to the login action, I don''t see the [add user] submit button?? I am sure this is connected to the

My second problem is: Listing users, and deleting them doesn''t work. If I try to list user, i just get this list: User Delete User Delete User Delete User Delete I''m using this code in the login_controller: def list_users @all_users = User.find(:all) end def delete_user @id = params[:id] if id && user = User.find(id) begin User.destroy

I am following the instructions on Agile Web Development with Rails book "Iteratio E1: Capturing an Order" section.

Hello. Where is there an Agile Messageboard? On the first part of the Depot example, a price field shouldn''t be an integer right? (it should be more of a float since a price has decimals) Dominic Son -- Posted via http://www.ruby-forum.com/.

I have been working through the Agile Web Development with Rails book doing the Depot tutorial. I have completed it and it works but I cant say I understand how and why. My question is this "After adding products to the Cart, how do I then give users the option to delete just one item and not empty the whole cart?" I''ve been playing around with all sorts of code, just making

Reading the Agile book, I can''t find a single command to save a collection. The save command seems to operate on only individual objects. Lets say I have a collection that I have received from a find_all command. I want to go through and change some attributes in various objects in the collection.
