• Name datetime columns with _at suffixes.
• Name time columns (referring to a time of day with no date) with _time suffixes.
• Name initializers for their gem name.
• Order ActiveRecord associations alphabetically by association type, then attribute name. Example.
• Order ActiveRecord validations alphabetically by attribute name.
• Order ActiveRecord associations above ActiveRecord validations.
• Order controller contents: filters, public methods, private methods.
• Order i18n translations alphabetically by key name.
• Order model contents: constants, macros, public methods, private methods.
• Put application-wide partials in the app/views/application directory.
• Use def self.method, not the scope :method DSL.
• Use the default render 'partial' syntax over render partial: 'partial'.
• Use link_to for GET requests, and button_to for other HTTP verbs.
• Use new-style validates :name, presence: true validations, and put all validations for a given column together. Example.
