Overview

Checks for multiple scopes in a model that have the same ‘where` clause. This often means you copy/pasted a scope, updated the name, and forgot to change the condition.

Examples:


# bad
scope :visible, -> { where(visible: true) }
scope :hidden, -> { where(visible: true) }

# good
scope :visible, -> { where(visible: true) }
scope :hidden, -> { where(visible: false) }
