Hi there, I would like to copy the schema and data from an existing database and create a development db with the schema and data. Is this possible? - I have heard of doing a ''schema dump'', what about a data dump. The data in the existing db is important - I worry that doing something could delete the data. Is this fear unfounded? Chris. -- Posted via

Hi there, Is a web app always preferable to a ''real'' app? - or are there times when a real app should be used? I''m starting a new app and can''t decide which would be best. Is Ruby (not RoR) suitable for a real app? Chris. -- Posted via http://www.ruby-forum.com/.

I am trying to run multiple instances of samba on the same unix host. This is being done so that I can functionally breakdown the usage into, for example, a "finance" server and an "engineering" server. This is not based upon the client or the user, but based upon the virtual server. My first attempts were a real problem in that, though the config file could be specified on

Hi there I''ve also made a start on the Agile Web Dev using Rails book! I''ve been hit with a problem when hitting the ''Add to Cart'' button - I get the following error message: ActiveRecord::RecordNotFound in StoreController#add_to_cart Couldn''t find Product without an ID RAILS_ROOT: ./script/../config/.. Application Trace | Framework Trace | Full

This is kind of frustrating (but no doubt helpful in the long run) that after following along and coding , and d/l the code the same error is appearing. For those who are familiar with the depot app, I''ve run into a problem after fixing the cart to reflect quanitites. I worked through the intended error messages but now have this appearing: SyntaxError in StoreController#add_to_cart

I am actually following the instructions/code snippets from "Agile Web Development with Rails" and got as far as page 73 where I did ruby script/generate controller Store index, then edited store_controller.rb to class StoreController < ApplicationController def index @products = Product.salable_items end end and product.rb to: def self.salable_items find(:all,

Hi, I am just learing Rails and I am going through the Agile Web Development with Rails book.

Hi I''m very keen to learn RoR and have been following the Agile Web Development with Rails book (first edition). However, I''ve come across a problem which has had me stumped for days now. After following the instructions up to page 85 I have tried testing the code thus far, as suggested, by adding an item to the cart. But I am getting the following error: --

I was successful in reaching page 184 in the book "Agile Web Development with Rails" 3rd edition and while running the website with PostGreSQL as the backend, the power went down. The PostGreSQL database contents look OK and so do the source code files I was editing. But whenever I click on any "Add To Cart" button in the catalog, I get the following information in the

I am really new to Ruby and Rails but as you probably see I am trying to get the shopping card working from the book. I am getting this error but I really don''t know what to do. I have looked up several of topics that stated the same problem but as far as I am, nothing has helped me out yet. Is there something wrong with the Product model? This is in the StoreController and I believe it

I''m new to Ruby and to fairly new to programming. I''ve been working through the "Agile Web Development with Rails" book, and I''m stuck on page 73 of the print version.

Hi, I've seen posts (but no answers) about clearing a file lock on a Samba share. Presumably this kind of thing happens when the program abnormally terminates and doesn't close its open files.

I have an e-commerce site and users check out with a form. The results of that form are sent to a "confirm your order" page via POST. I take great pains to NEVER store the full credit card number on my server--just the last 4 digits. I was very surprised to find that by default Rails will record POST requests with parameters in the production.log. And those parameters

Hello! I wish to generate random binary trees in R. Unfortunately recursive code like: t <- function(p) { list(ifelse(runif(1)<p,t(p),0), ifelse(runif(1)<p,t(p),0)) } does not seem to work. Has anyone ever performed such a simulation? I would like to see their code. Maybe this is not feasible in R. Please e-mail me at the below address (since I am not yet a subscriber to this
