The code here is a tech demo showing how to switch between databases in Rails 5, in a thread-safe manner.

BACKGROUND: HOW NOT TO CHANGE DATABASES

The simple way to switch databases is:

ActiveRecord::Base.establish_connection :user_shard1
puts User.find(1) # this is executed on the database keyed on "user_shard1" in database.yml
ActiveRecord::Base.establish_connection :development

Adding your own channel greeting

All you need to do is to add your own text in the greetings.yml file.

Example

CHANNEL_NAME:
  text: |
 This is a multi line message

‪“‬In what way is JS any more maintainable than CSS? How does writing CSS in JS make it any more maintainable?”

‪Happy to chat about this. There’s an obvious disclaimer that there’s a cost to css-in-js solutions, but that cost is paid specifically for the benefits it brings; as such it’s useful for some usecases, and not meant as a replacement for all workflows. ‬

‪(These conversations always get heated on twitter, so please believe that I’m here to converse, not to convince. In return, I promise to listen to you too and change my opinions; I’ve had mad respect for you for years and would consider your feedback a gift. Also, some of the stuff I’m writing might seem obvious to you; I’m not trying to tell you if all people of some of the details, but it might be useful to someone else who bumps into this who doesn’t have context)‬

So the big deal about css-in-js (cij) is selectors.
