The talk is about the gotchas of ActiveRecord callbacks even in the most common usage patterns and touches upon some possible alternatives to avoid each of these pitfalls. As Rails developers most of us would have inevitably have run into callbacks. This is something easy to get started with but is even easier to lead you into unexpected behaviour in production. Also, due to their unobtrusive nature they can become forgotten landmines. Structured in the popular and fun “WAT” style, the focus is mostly on beginner to intermediate levels, others might find one or two anecdotes surprising.
