In Active Record you can use named bindings in where-conditions. This helps you to make your code more readable and reduces repetitions in the binding list.

Example without named bindings

User.where(
  'name = ? OR email ?',
  params[:query],
  params[:query]
)

Example with named bindings

User.where(
  'name = :query OR email :query',
  query: params[:query]
)
