# Preloading usually required an extra query.
# To do it in one query, a `join` is needed, and the call to `preload` needs to know the name of join
# This macro does both the `join` and `preload` together
defmodule Preloader do
  import Ecto, only: [assoc: 2]
  alias Ecto.Query.Builder.{Join, Preload}

  defmacro preload_join(query, association) do
    expr = quote do: assoc(l, unquote(association))
    binding = quote do: [l]

Thanks to the original blog post: https://equimper.com/blog/how-to-setup-tailwindcss-in-phoenix-1.4

1. Install tailwindcss and postcss-loader from npm:

cd assets
npm i --save-dev tailwindcss postcss-loader postcss-import

2. Initialize tailwind (still in assets directory)

# This script will remove automatic association for all networks not listed in the whitelist
# passed as the first argument. Passwords will NOT be removed from the Keychain.
#
# Alternatively, you can untick "Remember networks" in Network Preferences > Wi-Fi > Advanced,
# but then you won't be able to auto-join networks even temporarily, and you might already
# have a long list to go through.

When does terminate/2 get called in a gen_server?

This is what the [official documentation][1] says about the terminate/2 callback for a gen_server:

This function is called by a gen_server when it is about to terminate. It should be the opposite of Module:init/1 and do any necessary cleaning up. When it returns, the gen_server terminates with Reason. The return value is ignored.

Reason is a term denoting the stop reason and State is the internal state of the gen_server.

Reason depends on why the gen_server is terminating. If it is because another callback function has returned a stop tuple {stop,..}, Reason will have the value specified in that tuple. If it is due to a failure, Reason is the error reason.
