Neeraj Singh on Callbacks in Rails3

  • Nov 9, 2010 · 7:00 PM
  • This location is shown only to members

Callbacks are important part of Rails. It is used everywhere from before_filter in controller to after_destroy in ActiveRecord. Callback code has undergone a lot of change in Rails3. Beside discussing the changes from Rails2, the presentation would go in detail how exactly Rails3 made callbacks faster. The talk will also discuss a few things to watch out for while declaring callbacks on ActiveRecord. We also have two lightning talks lined up: Matt Scilipoti will show us how to create new Homebrew formulas and Josh Szmajda will teach us how to use Plucky to easily query Mongo.

    Neeraj did a great job. Sense of humor and learned a few things. What more could you ask for.

    A (semi) deep dive into Rails 3 Controllers. Very clear. "So THAT's why it does that."

    Neeraj did an excellent job. It was very technical content but presented in a way that both intermediate and advanced developers could understand.

    I have a new (October) 15 minute overview on Ruby Refactoring. Is that too long?

    That sounds good Matt. I'll put you on the agenda-- anyone else interested in giving a lightning talk?

    I can do a lightning talk on creating a Formula for homebrew (supporting a new app/library).

    There are no lightning talks lined up (Nick won't be giving one). Is there something you want to talk about?

    Are there any lightning talks besides Nick?
