Rubocop has a uniqueness validator if the index is missing. So if validation for uniqueness is present, it searches for indexes in the schema. I don't get how does it work with scopes.
My model validations:
validates :name, presence: true, uniqueness: { case_sensitive: false, scope: :group_id }, length: { maximum: 20 }
validates :url, presence: true, uniqueness: { case_sensitive: false, scope: :group_id }
Added indexes on columns:
add_index :rss_sources, [:url, :group_id], unique: true
add_index :rss_sources, [:name, :group_id], unique: true
Rubocop is returning an error:
Rails/UniqueValidationWithoutIndex: Uniqueness validation should be with a unique index.
How to handle unique indexes when scope is present?
