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

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

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

quantic phenomena in migrations
I have an application with 15 migrations under version control. In a Mac and and in a Windows, a rake migrate from scratch runs them all just fine.

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

eager loading and polymorphic associations
There is a dedicated section about eager loading in the docs. A coworker discovered eager loading does not work in polymorphic associations the hard way :-) so I''ve written a patch that documents it: http://dev.rubyonrails.org/ticket/10610 There are at least a couple of tickets that implement something that would change that though: http://dev.rubyonrails.org/ticket/9640
