similar to: Regexp - date validation

Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it. Understand - I''m just asking this question to help them. I have been using Regexps since ''grep'' on Xenix! But the newbies here might not know how to do this:

This plugin gives ActiveRecord the ability to do stricter date checking. Example: class Person < ActiveRecord::Base validates_date :date_of_birth end This will ensure that date_of_birth is a *valid* date. The date can be set initially as a string in any of the following formats: "2006-01-01" "1 Jan 06", or "1 Jan 2006" "1/1/06" # Day /

When you first visit my site, you see a snippet (the first 75 words) of the most recent post. If it exceeds 75 words, a link will be appended to extend the post and read it in full. Now, my problem is when I post a code snippet, and I use "pre" tags to preserve its formatting, I don''t want that to show up on the snippet... only on the full version of the post. The reason is

Hi, since rails 2.2 doesn''t work with gettext anymore I decided to use a gettext dummy method until the gettext team relases a working version for rails 2.2. My application doesn''t need any i18n support right now and this way i figured it would be very easy to integrate gettext later. Just setup the plugin and go. So I need a method called _ which is available in alle models,

Hi Guys, I need to extract a text string from a longer text string. Both strings are variable in length and the text to extract is always between recognizable characters or tags (or the text to extract is from a known distance from said tags). I''m not an expert at text manipulation in ruby so it would be great if someone could recommend the best solution. I''m looking at the

Hi, Everything is in the title. With Rails 2.3.4 and MySQL 5.0.41: If have a table like this: +----------------+------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL |

Is there a difference in the way that params[] and @params[] are handled? Is the ''handling'' done by Ruby or Rails? A pointer to the relevant documentation would be sincerely appreciated. Or just an answer would be ok too ;-) Thanks, Bill -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, I have a user login form which the browser keeps populating because of its form fill feature. So when anyone goes to log in it shows the previous login''s username and password.

Still a semi-newbie, but so far I''ve managed to solve most things with a bit of help from the Agile book, some googling around, and a bit of trial-and-error, but I''m really stuck with this one (very much an Ajax newbie): I know how to gracefully degrade an AJAX newpost type call so it can appear inline or (for those without JS support) go to a new page (put an ":href

I thought I would write a lottery number generator since I have not had any luck winning the big jackpot - http://megamillions.com/. So far, after over 1.2 million tries, I still have not hit all the numbers from yesterday: 2, 17, 22, 32, 51, 35 (last one is the mega ball). Fun little project that and I thought others would be interested. Let me know if you have a cleaner implementation in mind.

Hi all, I''m having a very odd problem with db:migrate. I''m using Rails 1.2.5 on Windows XP SP2 and Ruby 1.8.6 I have seven migrations. If I run them with an empty database, it runs the first three, then halts. When I look in schema_info, the version is 3. If I run db:migrate VERSION=7, then it runs through the remaining 4 migrations, and the version is 7 in the DB.
