similar to: validator to ensure two fields are different?

I have been very VERY frustrated for the past week trying to solve a seemingly spurious problem with my Windows XP SP2 box with Ruby 1.8.2/Rails 1.0.0/MySQL 5.0.16 or 4.1.15 (yes, I tried both) installed running against a remote MySQL server that was either 3.23 or 4.1 (4.1.15 to be exact--we finally matched them both up to make sure that wasn''t the problem). So I post it here (as

Hi, I''m considering migrating my site from php to RoR. I''ve installed RoR gone through the onlamp tutorials and made the recipie/todo list sample sites and tinkered with a few of my own. I understand the examples that use models and scaffolding to map tables, but I''m having a little trouble understanding how to handle general purpose queries. A few people have

Hi Everyone, This is basically an FYI because I don''t think there is much that can be done about it. I work at a DoD lab and up until very recently I had no problems at all getting to rubyonrails.org. All week long I have not been able to visit the site and I finally gave up and submitted a trouble call to our network help desk. I was told that the site was in a class B range

I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I''ve used GDChart in the distant past but I

I have some code in my controller which looks like this: if request.post? and @account.save and @user.save ... end and in my Account and User models I have many :validates, like so account.rb validates_presence_of :subdomain, :on => :create validates_uniqueness_of :subdomain, :on => :create, :message => "is already being used" validates_exclusion_of

I have the following validation code, however it will allow variations in case. Like ''Admin'' and ''admiN'', etc validates_exclusion_of :login, :in => %w( admin ), :message => "is reserved for system accounts" how can I make this validation case insensitive? -- Posted via http://www.ruby-forum.com/.

Quick question: I have an array of reserved words that I want to share across most of my models so I can do something like this in the models: validates_exclusion_of :username, :in => RESERVED_WORDS, :message => "This username is a reserved word. Please choose another." Here is a sampling of the the array: RESERVED_WORDS = %w( blog blogs forum forums search login logout signup

I've been attempting to get to get Shared Folders and ACL's to work under dovecot 1.0rc17. Unfortunately, I've run into some problems (many have already been mentioned on the list), specifically the problem where folder-specific ACL files are not found (and I will not use Global ACL's due to the 100% probability of cross-namespace mailbox name conflicts). My namespace

Validates Unlike Plugin (v 0.1) ======================== Validates Unlike plugin validates that the value of the specified attribute doesn''t match against the regular expression provided Class Contact < ActiveRecord::Base validates_unlike :comment, :with =>/html|http|onclick|onmouseover/ , :message => "comment can''t include: href,http,onclick,onmouseover."

Well, I guess I''m successful because within a month of getting my very first application online (and it''s barely functional) I now have to get a second one up pretty quickly. Basically, I have a rails application "myFirstApp", and a hostname www.myfirstapp.com. Now I have a second rails app "mySecondRailsApp" and I need www.mysecondapp.com to peacefully

I have been running a public MySQL server for over 4 years. The system was a 1GHz box with 256MB of RAM. MySQL puts each database into a seperate directory in a single "data" directory. Once the old system reached about 10K databases the connection times increased 10X or more. I attributed the speed problems to a possible filesystem limitation with a large number of files. That

I work with a MySQL installation containing several thousand databases. MySQL represents each database as a seperate sub-directory of the main MySQL data directory. As the number of databases increases it seems that the time to connect is increasing significantly and I believe this is probably due to the time necessary to search through the large number of directory entries. It has been

I''m running a simple WEBrick server for a small rails website. I probably get less than 100 hits per hour. I just looked in /tmp on the server and there are over 10,000 ruby_sess.* temp files containing: " hash{" flashIC:''ActionController::Flash::FlashHash{: @used{ They''ve piled up so much that I can''t even rm -f ruby*. Bash complains

Greetings Everyone, A group in my office is designing/integrating what I would loosly label as an "embedded system". In that, it performs a dedicated task and is not a general purpose workstation or server. It operates in a harsh environment, particularly a questionable power environment and they are extremely concerned about inadvertent shutdown and recovery. They were totally

I developed a small RoR app on my Ubuntu laptop and I just tried to migrate it to my "production" box which is Fedora FC3. I moved the entire rails app. I received this error when I tried to get the first page: [2005-11-17 15:36:00] INFO WEBrick::HTTPServer#start: pid=32546 port=3000 192.168.0.61 - - [17/Nov/2005:15:40:01 EST] "GET /freesql HTTP/1.1" 200 0 - ->

I have a situation in which I want to validate a number is not zero. Both positive and negative values are acceptable, just not zero. validates_numericality_of has an :equal_to attribute, but I don''t see a :not_equal_to. I have not yet been able to find anyone who has discussed this. I did find information about custom validators, so I am now using a custom validator to check the field

Hi everyone, i have 20 fields in users table. in my admin profile module the admin can modify his infomation. but only 12 fields he can able to modify. so in my controller if params[ :profileinfo ][:first_name] @profileinfo.update_attribute(:first_name,params[ :profileinfo ][:first_name]) end the above simply saves what i enter into the field.why it doesnot consider the modelvalidation.

Hello, I''m trying to build an app (mysuperapp.com) that allows users to create an account in which a default subdomain (IE: joeshmoe.mysuperapp.com) will be created as their homepage. In their profile settings, I also want to give them the ability to add their own domain name so their homepage now can be joeshmoe.com. I know this is possible in rails w/ plugins like subdomainfu

Hi all, I''m new to rails. I have created a bunch of CRUD code using scaffolds. I had to add code to the default output to account for fields that establish the relationships between tables. Everything works well, including the validation of the fields I added. However, I can''t get the highlighting to work for my fields when they fail validation and the view is redisplayed.

For whatever reason I decided to implement the validator class tonight. It''s my first go at implementing the class. My first run at it looked pretty good. I just added a generic .i for it and it all compiled. Sadly, the samples didn''t work because the base Validator class can''t actually be used as a validator! You have to derive from GenericValidator. I
