A Rubocop wrapper that checks only added/modified code
#!/usr/bin/env ruby
# A sneaky wrapper around Rubocop that allows you to run it only against
# the recent changes, as opposed to the whole project. It lets you
# enforce the style guide for new/modified code only, as opposed to
# having to restyle everything or adding cops incrementally. It relies
# on git to figure out which files to check.

# Here are some options you can pass in addition to the ones in rubocop:

When Active Record Child Objects are Autosaved in Rails

belongs_to:

  1. Assigning an object to a belongs_to association does not automatically save the object. It does not save the associated object either.

has_one:

  1. When you assign an object to a has_one association, that object is automatically saved (in order to update its foreign key).
  2. In addition, any object being replaced is also automatically saved, because its foreign key will change too
  3. If either of these saves fails due to validation errors, then the assignment statement returns false and the assignment itself is cancelled.
  4. If the parent object (the one declaring the has_one association) is unsaved (that is, new_record? returns true) then the child objects are not saved. They will automatically when the parent object is saved.

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
