Rails mailer structure

Your application is growing, and you are starting to have a complex mailing system: notification emails, retention emails, misc user emails, admin emails, etc...

It's time to clean up your mailers !

Existing mailer

You may already have a single mailer, responsible of every emails, like this one:

sudo apt-get install build-essential autoconf locate
sudo apt-get install git guake zsh curl vim vim-gtk3 postgresql-client \
postgresql postgresql-contrib redis golang direnv tmux bat ripgrep fzf
curl -L http://install.ohmyz.sh | sh
chsh -s /bin/zsh
zsh

Rails Rspec APIs Testing Notes

Folders Structure

1. Your class can be no longer than 100 lines of code.
2. Your methods can be no longer than five lines of code.
3. You can pass no more than four parameters and you can’t just make it one big hash.
4. When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.
