Bye removes the Rails methods try and try!.
90% of try usage in Rails is either a flagrant Law of Demeter violation or more simply a betrayal of single responsibility. Bye forces you to be confident in your code: using the null object pattern, better delegating of methods, or just using fewer chained methods.
Add this line to your application's Gemfile:
gem 'bye'And then execute:
$ bundle
Or install it yourself as:
$ gem install bye
Bye works without any extra setup.
Without Bye:
User.first.posts.try(:collect, &:foo).try(:uniq).try(:sort)
=> nil
With Bye:
User.first.posts.try(:collect, &:foo).try(:uniq).try(:sort)
=>
NoMethodError: undefined method `try' for #<ActiveRecord::Associations::CollectionProxy []>
