Hi all, Here''s another contribution for anyone interested. In Railscast episode 28, Ryan Bates showed us in_groups_of which allows you to group array members such as >> list = [1, 2, 3, 4, 5, 6, 7] => [1, 2, 3, 4, 5, 6, 7] >> list.in_groups_of(3) => [[1, 2, 3], [4, 5, 6], [7, nil, nil]] This allows you to iterate over the groups and, for example, display a list

Hi... I want to know the equivalent instructions to insert, update, search and delete a registry. I know Rails can do it easily Thanks to ActiveRecord, but here''s the catch: I''m using PostgreSQL. As I''m using SQL to do the migration (Including the foreign keys), I need to know if I can use SQL queries to do those actions. Is there an example out there? I uncommented

I have been scratching my head on this one for most of the day. Hopefully someone can help explain why before_filter isn''t working for my codes. In my Application controller, I have this: before_filter :login_required, :except => [:newacct, :create_newacct, :passwd_reset ] def login_required unless session[:user_id] flash[:notice] = "Please log in"

Hi guys, Is there an elegant way to capture the sql that would have been executed by an ActiveRecord statement, without actually executing it? :) I''m imagining something like sql = User.find(1).groups.to_sql or perhaps sql = ActiveRecord::Base.capture_sql { User.find(1).groups } resulting in sql = ''SELECT * FROM groups INNER JOIN memberships.... WHERE users.id =

Hello Rubyists, I''m currently trying to get email hooked up via ActionMailer, and while I''ve gotten it to work in the past on Rails 1.2.x, I''m seeing an error that I''m unfamiliar with.

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 all, I have a complex link_remote_to link I need to generate often. I want to DRY up my view and create a helper that generates this link_remote_to for me. Is there a way my helper can output the link_remote_to javascript?

I don''t know if HAML questions are appropriate here ... but here goes. How does on end line to be rendered with a vertical bar (|) ? The vertical bar is a line continuation, aparently.

Browserized Styles provides a dead simple way to create browser- specific CSS code for use in a Rails application. All you need to do is create a .css file targeted to a browser by appending an underscore and identifier to the end. === Installation === script/plugin install http://svn.intridea.com/svn/public/browserized_styles === Example === Let''s say I have some complex CSS code

I''m still trying to work into Ruby 1.9.2 and am now experiencing something that makes no sense to me. Using rspec 1.3.2 and rspec-rails 1.3.4 with rails 2.3.11 on ruby 1.9.2-p180, when I $ rake spec:models they all pass. When I $ rake spec:controllers they all pass. When I $ rake spec:views they all pass. But when I $ rake spec I get <path to

Hi all, I''m posting this in the hope that someone who understands rails dependencies can shed some light. I''ve implemented a "ModelSecurity" module in the vein of Bruce Peren''s old ModelSecurity plugin (http://rubyforge.org/projects/model- security/). My ModelSecurity module lives in $RAILS_ROOT/lib. It is automatically included into ActiveRecord::Base by a

Hi, I have wasted few days and I''m not getting anywhere. I was trying to follow tutorial on Rails Guides and this one: http://www.tutorialspoint.com/ruby-on-rails/rails-send-email.htm . All I need is to be able to send some text, nothing fancy. Why in Rails it has to be so difficult? Why it can''t be so simple as in PHP? Can anybody point me to some good simple tutorial,

Hi, I know that it''s possible to use multiple databases with Rails. However most of the examples I have seen were for high availability. I would like to learn if anyone has any experience with a shared database among many rails applications. Such a case may make sense for shared user information. Any ideas? Thanks. -- Ersin Er --~--~---------~--~----~------------~-------~--~----~ You

I finally settled on Ruby, one of the reasons being that I didn''t want my language to tell me how whitespace should work. (Although the main reason was how object oriented Ruby is) Although
