dependent support for has_many through?
Given the following class Programmer < ActiveRecord::Base has_many :assignments has_many :projects, :through => :assignments end if I call Programmer#projects.clear, it will delete_all the joining assignments; however, I have a situation where I''d like the assignments to get destroyed instead so that their after_destroy callbacks get called. It would be simple to

migrations and SQLite
I read in the instructions of Tracks that "upgrading via the rake migrate command is quite a bit more tricky currently with SQLite and SQLite3". Is there any gotcha regarding migrations and SQLite3? -- fxn

compress and max upload size?
I am using mongrel_cluster with mod_proxy_balancer and would like to enable compression (assuming it improves throughtput) and limit file size upload. I configured mod_deflate and LimitRequestSize in Apache, but in my trials looks like the proxied calls bypass those directives (the conf goes below). Is there a way to get this? -- fxn # Adapt this .example locally, as usual. # # To be

History plugin
Hello, I felt annoyed enough when having to redirect user back to their previous location in a hackish way that I wrote this plugin. It avoids storing POST and Ajax request. It also has a facility to specify actions not to store in the history. If you are interested, it''s there: http://blog.cosinux.org/pages/rails-history See you all, Damien -- Damien MERENNE

can you explain this benchmark?

Is this a bug in Ajax handling?
When a controller responds to a link_to_remote with a redirect_to, the link_to_remote gets a success callback, this would seem like a bug to me, at a minimum it should return a failure? This is driving me crazy because all the login engines/generators respond to an authentication error with a redirect_to. The work around is to change them to all do a render :layout => false, :status => 500

after_(read|find) callback?
I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

elemental race conditions question
What''s the standard way to prevent race conditions in controllers? Say user has many posts. Post controller has action add_post that receives user id, post controller find()s the user and while he is creating the post entry an administrator deletes that user in a separate session. We cannot assume the database checks foreign key integrity. How do you get that right? -- fxn

when is model() needed?
I have just some vague and thus probably wrong ideas about when to use model() in controllers, and by now I err on being redundant. I don''t post them here to avoid leaving anything that may be false in the archives. Can anyone explain exactly in which cases one should use model()? -- fxn

actions with no views?
In Depot, the demo application in the the Agile book, actions that modify the model such as add_to_cart redirect to another action that has a clear view role, like index, or show_cart, instead of generating the view themselves. This uses an HTTP redirect that goes to the client and returns. Is this an idiomatic way to design the flow in Rails? -- fxn

Applications used in the Rails video?
Hi all, I just watched the rail video: http://www.rubyonrails.org/media/video/rails_take2_with_sound.mov I am just curious. I can tell that the video was done on a Mac, but I cannot tell which applications were used for editing the code, and for interfacing with MySQL database.
