If you do not set the + `:inverse_of` option on the association, then Active Record will guess the + inverse association based on heuristics. + + Note that automatic inverse detection only works on `has_many`, `has_one`, + and `belongs_to` associations. Extra options on the associations will + also prevent the association's inverse from being found automatically. + + The automatic guessing of the inverse association uses a heuristic based + on the name of the class, so it may not work for all associations, + especially the ones with non-standard names. + + You can turn off the automatic detection of inverse associations by setting + the `:inverse_of` option to `false` like so: + + class Taggable < ActiveRecord::Base + belongs_to :tag, inverse_of: false + end + + *John Wang* + * Fix `add_column` with `array` option when using PostgreSQL.
