title: Is there a Rubocop configuration specifically for rails 5.2.3?
body: <p>I have just created a fresh Rails application using <strong>Ruby 2.6.3</strong> and <strong>Rails 5.2.3</strong> and the only thing I have done is installed <strong>Rubocop</strong>. </p>
  
  <p>After installing <strong>Rubocop v0.70.0</strong>, and running <code>bundle exec rubocop</code> I get 89 offences. After running <code>rubocop -a</code> to fix them automatically, I am still left with 34 offences. Is there a configuration I am missing for a rails project or will I need to manually fix these offences?</p>
