Problem Statement
There were code smells detected in the application by code climate which violated the best practices of Ruby Rails. The goal was to fix those code smells by refactoring. e.g. 1. belongs_to :topic, class_name: 'SignUpTopic'.
In the class 'SignUpTopic', we have has_many :teams
When you have two models in a has_many, has_one or belongs_to association, the :inverse_of option in Rails tells ActiveRecord that they're two sides of the same association. Knowing the other side of the same association Rails can optimize object loading and will reference the same object in memory, instead of loading another copy of the same record.
2. in the file roles.rb we have has_many :users
We need to specify "dependent" option here.
