DEPRECATION WARNING: The following options in your Gallery.has_many :gallery_images declaration are deprecated: :order. Please use a scope block instead. For example, the following:

    has_many :spam_comments, conditions: { spam: true }, class_name: 'Comment'

should be rewritten as the following:

    has_many :spam_comments, -> { where spam: true }, class_name: 'Comment'

People also forget when defining scopes in the first place to use lambdas. I've seen this about eight gajillion times:

class SomeClass < ActiveRecord::Base
  scope :truthy, where(:some_boolean => true)
end

Cue homophone replacement-level rage.
