Hi guys, When I do: temp = User.find(:all, :joins => "INNER JOIN contents ON users.agent_id = contents.id", :select => "contents.id, users.id, users.u_date") temp.first.inspect It seems to work fine, but it only returns: #<User id: 6, u_date: "2009-10-03 19:32:23"> but not the contents.id information.

Here is the situation: - the client makes a request - it is followed by AJAX polling The server needs to keep track of some stuff during this process. I have been using the Session and it "mostly" works… until the user decides to open another tab in her browser and she makes a new, parallel request. In this case, the data from the two requests is merged, which leads to bugs. This got

Hi guys, In my Rails app, I have three models: A, B and C, with the following relationships: - B hasMany C - C belongsTo B I would like A to "has_one" instance of B+C. By that I mean A needs to be linked to a specific instance of B AND a specific instance of C. My first guess would be to create a fourth object, say B_plus_C that would: - belongs to B - belongs to C - belongs to A Is

After installing the PessimisticLocking plugin I noticed that ActiveRecord''s count method no longer works (see below). If I remove the plugin it resolves the problem. I need both. Any ideas? I have also read that Pessimistic Locking is now baked into ActiveRecord in Edge Rails. I have tried Rails 1.1.2 and 1.1.4 and that doesn''t seem to be the case. Any idea when

I run Resque with x ''general'' queues. With ''general'' I mean a queue that may run every type of Worker. Or in the Rake command: COUNT=x QUEUE=* rake resque:work When a worker runs a job of a specific class, it may not run another job of the same class simultaniously. This job has to wait until the previous job has finished before it may start. BTW The reason

Hi, I have implemented resque scheduler in my application by looking at example here https://github.com/bvandenbos/resque-scheduler. I have configured resque_schedule.yml file, and in that I can pass arguments to the resque job. My requirement is to pass more than one arguments to the queueing resque job.

In pre Rails 3 world I was using ar_sendmail to queue up emails. Then I would setup a cron job every few minutes to deliver the emails. But that doesn''t work perfectly in Rails 3.

http://stackoverflow.com/questions/16770090/storing-rails-controller-callback-data-in-session The idea is: - Perform some time consuming action in background. - Have the results from that action be propagated back to the controller using a callback. - Store the result in an in memory session store. - Have the result in session be used and available from that point onward.

I have contributed a "gam" library to CRAN, which implements "Generalized Additive Models". This implementation follows closely the description in the GAM chapter 7 of the "white" book "Statistical Models in S" (Chambers & Hastie (eds), 1992, Wadsworth), as well as the philosophy in "Generalized Additive Models" (Hastie & Tibshirani 1990,

Hi, I have a Rails 3.2 app. There is a specific request that takes a long time to execute.

Hi guys, I need my app to make a few hundreds requests to external web services as quickly as possible. The web services are fairly fast, but still: if I do the requests one after the other, it is too slow. My understanding is I have two options: a- Threads. b- Typhoeus Typhoeus seems great. Yet, the web services are all quite different (some are SOAP, some REST...) and therefore wrapped into

Hi, I''m wondering why SIGINT and SIGTERM both were chosen for the quick shutdown? I agree with SIGINT but not with SIGTERM. A lot of unix tools send SIGTERM as default (kill, runit among some) and it seems to be the standard way of telling a process to quit gracefully but not among Ruby people (there are a few other ruby processes behaving the same way). I just think it''s weird

I''m loving playing around with the DSL. There are some problems (ie 5237), but now that it''s Ruby, I can fix them! woo!
