I''ve completed the chapter on Internationalization successfully, but found out just recently that the "Who Bought" function produces an error page that looks very ugly when someone enters a product ID that does not exist.

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

Hi, I''m reading the "Agile Web Development With Rails" book. So long, everything has worked fine, but now I got this annoying error message that I just can''t understand. The error appears for me around page 87, chapter 8. NoMethodError in Store#display_cart Showing app/views/store/display_cart.rhtml where line #28 raised: undefined method `product''

Dear All   I have the following code set up: Code #1 a <-matrix(seq(0,8, by = sign(8-0)*0.25)) b <-matrix(seq(8,16, by = sign(16-8)*0.25)) c <-runif(1000,50,60) d <-exp(-c*a)+exp(-c*b)   This will give me the obvious error message of lengths not matching. What I am trying to do here is to have 33 rows x 1000 columns d values calculated in total.

Please excuse my first couple of probably quite a few newb questions. Are there still probs with viewing chm files? If I browse to the chm file and just launch it seems fine until I try search for a subject. I search, find what I'm looking for, click it and the help file closes. If I use wine hh / winepath windows path it launches but if I click search I can't try the search, it's

Quick newb question about R relating to the line of code below: rawCool = read.zoo("cooling.txt", FUN = as.chron, format = "%m/%d/%Y %H:%M", sep = "\t", aggregate = function(x) tail(x, 1)) I'm wondering what the specifics are for the argument where it has "aggregate = function(x) tail(x, 1)". I understand that it removes the last row of

I think im using Gnome but im not sure. As for using logout command it didn't work that's why I got puzzled and had to ask online since I couldn't find the GUI one which was there but apparently im too blind to see.

Model for post is "belongs_to :user" In a slightly modified scaffold I can list all the posts and which user wrote them (/post/list), but want to link the username to a list of posts by that user. How do I accomplish that? Sorry for the

If you really want to do this the asterisk list is based off of mailman. You can learn all about mailman here: http://list.org/ But really, what are the odds that newbs will know to go there first? Are you going to moderate it? Someone has to actually answer the questions you know, if a newb only list is going to exist. Look, don't answer lame questions if you don't want to. Flaming a

I am using this line on my index.rhtml page to capture the quantity required of a particular item for a basic shopping cart app: <%= text_field ''line_item'', ''quantity'', {:size=>3} %> </td> but my next screen (a cart screen) doesn''t reflect what was entered in that text field when the item is added to the cart. That is,
