I''m digging into rails source code. But I''ve got a problem in undestading actionrecord::base source code which is connection_specification.rb. In the body of establish_connection method, def self.establish_connection(spec = nil) case spec when nil raise AdapterNotSpecified unless defined? RAILS_ENV establish_connection(RAILS_ENV)

Hello fellow RoR users, I am a newbie and I thought RoR is so easy to set up and that I would be saving so much time -- but I am still waiting to save time because I simply couldn''t get Ruby/Rails to talk to MySQL (5.0.18) at all. Here are the steps that I have examined: 1) I look at dabatbase.yml and put in the right information to talk to the database I have set up (the

Hi, I have problem to understand this line does exactly? this is from the class ConnectionSpecficication, methode "active_connections" def self.active_connections #:nodoc: if allow_concurrency Thread.current[''active_connections''] ||= {} else @@active_connections ||= {} end end what the line "@@active_connections ||= {}" means exactly? as I

I could use some eyes on https://rails.lighthouseapp.com/projects/8994/tickets/4368 if anyone has the time. Summary of the change: Similar to PredicateBuilder''s existing support for ''table.column'' => ''value'', this patch enables ''column#method'' => ''value''. For instance,

I have an application where user sets his/her preferred date/time format. User is expected to enter datetime in his preferred format across the application. Now the problem is for few formats the datetime is parsed wrongly while create/update ActiveRecord. For example user has set date/time format in hh:mm dd/MM/yyyy. Now if user enters 17:00 04/05/2012 it parses it as 5 PM 5 Apr, 2012 where it

Hi list, I made an open source CMS powered by Rails, named Rubricks. I have a web page for Rubricks. You can download it or view a flash demo there. Please try them and feed me back, like bug report etc. Check it out at: http://rubricks.org/index_en.html Thanks. Shouta

Hi Everyone, I''ve just updated my Rails install to 1.0 and have noticed that the ActiveRecord connection handling is somewhat different. I''ll explain... I''ve declared a block handler that will change the connection for ActiveRecord::Base prior to yielding to the block, then restore the original connection (see code snippet below). I''m doing this in order to

Hi, I really need help to understand what is happening while Rails connect to a database, (we area actually using postgresql, so my example will be with postgresql) What I understand is Rails is able to connect to different DB. Actually, this is what we want, and we have made some tests, everything is juste fine. However, all these tests lead us to some important questions that we did find the

Hello, I need to access an mirrored database with one read and one write cluster. Is there a way to tell a model to use two connections? So that all updates etc go to the write database and all read from the read one? This is a fixed set up I can not use MySQL 5.x stuff and additionally i get a token on write, which can be checked on read (and wait for replication) if new data is needed. I

Hello everyone, I would like to eager load scoped records to avoid queries executed in a loop (huge performance impact). The "scoped" part is what is giving me a hard time. I''m using Rails3 RC. Does anyone have any idea how I can do it? Here is a test case : we have an "Article" and a "Comment" Activerecord models, article has many comments comment

My migrations were working fine until today. I dropped and re-created the database.But, when I go to apply my migrations, rake migrate aborts with this error. You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occured while evaluating nil.first Any idea what might be wrong? The migrations look right. It''s talking to the

DHH''s acts_as_taggable is now much more usable with this patch. http://dev.rubyonrails.org/ticket/3866 This patch adds scoped finders, documentation, and tests: # Get tags for all articles in a blog @blog.articles.tags # Get tags for articles in a blog published in the last year @blog.articles.tags :conditions => [''published_at > ?'', 1.year.ago] # Get related

We''re seeing these errors intermittently: ### Mysql::Error: Lock wait timeout exceeded; try restarting transaction: UPDATE `chairs` SET `published_at` = NULL, `updated_at` = ''2008-07-30 15:31:05'' WHERE `id` = 2147 [RAILS_ROOT]/vendor/rails/activerecord/lib/active_record/ connection_adapters/abstract_adapter.rb:147:in `log'' ### The root issue is probably

I have a Project that has_many Tasks. Tasks belongs to a Project. When I try the following: project = Project.new project.tasks.build I get: >> s = Project.new => #<Project:0x25f9e28 @attributes={"name"=>"", "end_at"=>nil, "updated_at"=>nil, "published_at"=>nil, "user_id"=>nil,

We are running edge rails with oracle. After a few hundred requests all available sesions are used up. It seems prior connections are being left open. When this happens no one using the installation of Oracle can create a new session until you kill your mongrel/webrick server. Patch #6928 addresses this problem, and i applied it to my vendor rails and it worked. I think, if possible, this

The environment.rb file in a Rails 2.3.2 app says: > Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. Auto-convert to this zone... when? Also, what are the differences between these two statements? config.time_zone = xxx config.active_record.default_timezone = xxx I ask these questions because I have a scenario whereby an AR-backed object, when

Hi Folks, I believe I tracked down the problem with the leaked DB connections. The simple fix is to put: ActiveRecord::Base.threaded_connections = false In your environment.rb file right before environment.rb does any ActiveRecord use. For example, here''s mine: ActiveRecord::Base.threaded_connections = false ActiveRecord::Base.configurations =

Hey, I have a system that I am trying to design, it contains news articles, events, etc... There is model representing articles, one representing events, etc... Articles or events can be active or inactive, so I can do a query to return all active articles, all articles or all inactive articles. The question that I have is what would be the best way to design this. Right now I have each

I have a question about the usage of Merb::Controller#url. When I have nested resources, requesting the new action works differently than I expected. I was wondering what the intended usage is. For example: Say I have r.resources :articles do |article| article.resources :article_attachments end irb(main):002:0> show_routes [:articles, "/articles"] [:article_attachments,
