Hi, I''m 8+ hours reading and working through the book "Agile Web Development". My brain is now mush :) I have some php experience but that about the extent of my programming experience. Anyway, I do have a question - for those who know the book or those who don''t - The product table has a column for an image link ..i.e. /images/something.gif As part of the exercise

Hi, all, I''m a newbie on dtrace and the problem I am having is: For processes which have been running for more than a couple of hours, dtrace doesn''t seem to be able to trace(I waited for at least one hour and didn''t see anything happening). However, it works every time for a relatively new process. Any insight or help will be appreciated. This is my machine:

Hi, I am trying to convert email box in mbox format to maildir++. It converts all folders except INBOX. For example: dsync -D -v -f -u 'info at example.org' mirror 'maildir:~/Maildir' prints: dsync(info at example.org): Info: Sport: only in source So it converts Sport folder, but INBOX folder is ignored. dovecot.conf contains: mail_location = mbox:~/mail:INBOX=/var/mail/%u

Hi Team, Can you please guide us to remove SAMBA 3.0.24 completely from our SOLARIS Server as we don't require it anymore ? Thanks, Suganthi

OK, First, thanks for all of the help recently. I appreciate it. But...I have just implemented the cvs code as to be able to use the 'use client driver' option because win nt/2k machines have been seeing an 'Access denied, unable to connect' error for the print queues and this will apparently fix this. I will describe my setup and what I have done thus far: RH 7.1 Samba 2_2 cvs

Hello Everyone ! Wanted to announce the launch of a new, 100%, Ruby/Rails based shopping system. http://www.rightcart.com (our blog: http://www.rightcartblog.com) It''s basically a shopping widget that allows users to make purchases directly through the widget.... no need to be redirected to a third party shopping cart. You can sell anything you want by upload the products onto the

Hello- I have a database/rails design question. I''d like the user to be able to specify a set of fields they would like associated with items. Imagine a shopping cart where each item has a description and price. But a particular customer may choose to associated a color with all her items. (it will be site-wide, so every item listed for this particular user will have this

Hi, I have a spec it "should have a unique username " I have a code: validates_uniqueness_of :user_name Now, I don''t know how to test this code. In order to test this, do I need to run `save`? For example, @user = User.create(:username => "mike") @another = User.create(:username => "mike") @another.save.should be_false This messes up test

I have a shopping cart function, and I''d like to set it up to update the cart with AJAX. My AJAX call will return a view that displays the cart items. My question is with regards to keeping things DRY. When the user goes to "view cart", that page needs to display the cart, then the cart display needs to update with AJAX calls when items are added from that page. It would

First of all id like to say hi to everyone from Argentina, im yet another Depot first-timer. Going through the example, i got to the point where my cart finally runs Ajax-based. And there is a line where Dave says, after all the job is done "You should see the cart in the sidebar update. And you shouldn''t see your browser show any indication of reloading the page. You''ve

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

Greetings! I could really use some help understanding what Rails puts into the session store related to the objects it creates. I''ve found documentation on how _I_ can put / get info into it, but can''t find the docs on what _Rails_ puts into it. I''ve got a simple app that collects some data from the user, stores it in a db record, allows the user to edit it, display

Dear all, Just wondering if someone could help me out converting my code from a for() loop into a foreach() loop or using one of the apply() function. I have a very large dataset and so I'm hoping to make use of a parallel backend to speed up the processing time. I'm having trouble getting selecting three variables in the dataset to use in the foreach() loops. My for() loop code is:

Hi! I'm a recent convert from Stata, so forgive my ignorance. In Stata, I can write foreach loops (example below) foreach var of varlist p1-p14 { foreach y of varlist p15-p269 { reg `var' `y' } } It's looping p1-p15, p1-p16...., p1-p269, p2-p15, p2-p16,... p2-p269,... variable pairs. How can I write something similar in R? I 'tried' understanding the

Hi all, I''m having trouble figuring out how to handle stock levels in a new store I''m building. When products are entered into the admin of the store, they have a stock number associated with them. What I''m not sure about, is how I go about maintaining this stock level. Take this scenario: 1. User A adds an item to their cart, and I check that it''s in stock -

I have a really horrendous problem with sessions. before_filter :find_cart_from_session private def find_cart_from_session if session[:cart] # if there''s is a cart in the session begin @cart = Cart.find(session[:cart]) # return existing or new cart rescue ActiveRecord::RecordNotFound @cart = Cart.create @cart.save session[:cart] = @cart.id
