I''m stuck in a catch-22 type problem. I have an insert form for a table that uses the validation in the model. i.e. When you click submit on the form and haven''t filled in the required fields then you get the nice rails error messages saying "field can not be blank". This works fine until I introduce some more logic. What I''m trying to do is to validate

I currently have a database with a table called bookstores. Within that table are columns such as bookstore name, city, state, and zip code. What I''d like to do is display the City and then every store name for that city underneath it. i.e. City - Store 1 - Store 15 Another City - Store 2 - Store 5 etc. I''ve seen act_as_tree but I don''t know if

Hi all, I'm currently gearing up for a possible PBX replacement project using Asterisk, and I'm just breaching the iceberg of information that's available. I typically like to have something thick with pages in front of me. Mahler's book was the first one to come up and it seems like a good place to start. However, the big name bookstores tell me it'll take up to three

Anybody know where I can get the Pinheiro/Bates book? I can't find a bookstore w/ stock and the publisher says they don't know when they'll have it again. Thanks. -Frank

I''ve looked through the messages regarding implementing a ZipCode search and I have a few questions to make sure I have my head wrapped around this. Here''s what I have. I have a database table called zipcodes with the following info (for example) 30310 Atlanta GA 33.727807 -84.41983 -5 1 That''s zip, city, state, latitude, longitude, timezone, and dst. So when a

I am hoping to find a inventory management program suitable for something like a bookstore or other 1-5 person smb. The software would need to be able to accept inputs from wireless handheld scanning devices for entry into the system. It must also work with their windows based PoS computer. Any suggestions would be highly appreciated. William -- My "Foundation" verse: Isa 54:17

Is there any package that I could use for zipcode search. I want to display schools that near a particular zipcode. I have no idea how to do this.

Hi All, I understand people have been frustrated trying to find copies of "The Official Samba-3 HOWTO and Reference Guide" edited by John Terpstra and Jelmer Vernooij. I apologize. Demand has been even greater than we anticipated and we immediately ran out of stock on the first printing. As bad luck would have it, the busy holiday printing season and a glitch at the printer delayed the

i've search the email archives, searched the documention of various map packages and done an R-site search, but have been unable to find direct resources for creating maps of the US that are colored or annotated or ... by zipcode data. For example, create a map of the US and color each zipcode region by its population using two vectors z,p containing the zipcode and population,

Hi All, I know there has been a lot of interest in John Terpstra's upcoming book, "Samba-3 by Example: Practical Exercises to Successful Deployment." The book is scheduled to print end of March and can be found at local bookstores by early April. In the meantime, John will be giving a talk at the BYU UNIX User's Group tomorrow, Thursday, February 19th at 8PM, where he will be

Hey, Does anybody know of a good Geocode library for Ruby, similar to Perl''s Geocode::Postal, that i could use in my rail app? I need to do some "within 5 miles" calculations of zipcodes and i dont have a nice ruby (or gem) utility to do it. any help would be appreciated. thanks adam _______________________________________________ Rails mailing list

Dear, I am trying to visualise a time-progressing line (it's supposed to represent spread patterns) using brew package and Google Earth. The idea is to have a function which takes start and end point geographic coordinates, as well as number of intervals to chop the path up, and returns the collection of points segmenting this line. Unfortunately my calculations fail for large distances,

I am regularly running into a problem where I can't seem to figure out how maintain correct data order when selecting data out of a dataframe. The below code shows an example of trying to pull data from a dataframe using ordered zip codes. My problem is returning the pulled data in the correct order. This is a very simple example, but it illustrates a regular problem that I am running into.

Ruby Cookbook is out. I browsed the book today at the bookstore. It looks very good with a section on Rails. There is no review on Amazon yet. Did anyone get a chance to review this book?

Dear, I built the generalized method of moments model to estimate the sales rank in the bookstore using plm package in R. The equation is: data1.gmm <- pgmm(dynformula(lnsales_rank ~ ln_price + avg_ham_rate + avg_spam_rate + num_of_ham+ num_of_spam + ship_code2 +ship_code3 +ship_code4+ ship_code5+ ship_code6 + ship_ code7, lag = list(0, 0, 0, 0,0,0,0,0,0,0,0,0), log =FALSE), data=data,

Hi All, Thanks to everyone who has written wanting more information on when "Samba-3 by Example" by John Terpstra will be available. The good news is that it is available right now through your local bookstore or online sites like Amazon.com. There are already a couple of very positive comments posted to Amazon. These indicate that if you want to get Samba-3 up and running, you'll

Thanks for reporting the bug below. You''re absolutely right. Renamed Range#to_s implementation to #mocha_inspect and checked first and last respond_to?(:to_f) as you suggested. Sorry for the delay - I wasn''t monitoring the rubyforge trackers. I am now!

Dear all, i have a programming problem that should be simple, though i am stuck with it. Please note that this is not a specific geonames problem, though i use it as an example - it´s just a basic problem with lapply. I use the geonames webservices with the R geonames packages which works almost smoothly. I have a vector of Zipcodes and i want to do a geonames lookup for all of them, which
