Justin Searls presents, "Tenderlove: the DHH story of a boy named Gary Bernhardt"

Short abstract

Ruby has heroes. Demigods who show us how to write better code. Turns out: they're just ordinary developers! This is the story of how I discovered that by becoming Ruby-famous. In the process, I learned our hero culture is toxic.

Want to keep Ruby weird? Stop listening to us (right after my talk).

A top-down look into Elixir (for Rubyists)

• Phoenix (as "Rails for Elixir")
  • Rails and Phoenix can get suspiciously similar
  • A code sample:
• controller.rb

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

module ActiveRecord::UnionScope
  def self.included(base)
    base.send :extend, ClassMethods
  end
  
  module ClassMethods
    def union_scope(*scopes)
      id_column = "#{table_name}.#{primary_key}"
      sub_query = scopes.map { |s| s.select(id_column).to_sql }.join(" UNION ")
      where "#{id_column} IN (#{sub_query})"
