Заранее спасибо за помощь.
Ниже, внизу моего поста, я обновил его с исправлением этой проблемы, частично благодаря Нарасимхе Редди. Надеюсь, это поможет любому с подобной проблемой после обновления до Rails 5.2. ОБНОВЛЕНИЕ: ActsAsTaggableOn 6.0 вышел и исправляет эту проблему.
Я недавно обновился до Rails 5.2, Ruby 2.5 и переключил свою базу данных разработки на PostgreSQL (9.3.18, gem: 1.0.0). Ранее эта проблема не возникала, и с тех пор были сделаны только вышеупомянутые изменения. Я использую гем ActsAsTaggableOn (5.0.0) для формы обзора, в которой используются два списка: love_list и Impro_List. Теперь при отправке формы я получаю следующую ошибку:
NoMethodError in CityReviewsController#create
undefined method `[]=' for nil:NilClass Extracted source (around line 56)
56: @new_city_review = @city.city_reviews.build(city_review_params)

Мой соответствующий код модели для ActsAsTaggableOn:
acts_as_taggable_on :love, :improve
Я использовал, согласно предложению ActsAsTaggableOn, их настройку миграции, выполнив команду:
rake acts_as_taggable_on_engine: установить: миграции
И вот как моя схема выглядит для этих таблиц:
create_table "taggings", id: :serial, force: :cascade do |t|
t.integer "tag_id"
t.string "taggable_type"
t.integer "taggable_id"
t.string "tagger_type"
t.integer "tagger_id"
t.string "context", limit: 128
t.datetime "created_at"
t.index ["context"], name: "index_taggings_on_context"
t.index ["tag_id", "taggable_id", "taggable_type", "context", "tagger_id", "tagger_type"], name: "taggings_idx", unique: true
t.index ["tag_id"], name: "index_taggings_on_tag_id"
t.index ["taggable_id", "taggable_type", "context"], name: "index_taggings_on_taggable_id_and_taggable_type_and_context"
t.index ["taggable_id", "taggable_type", "tagger_id", "context"], name: "taggings_idy"
t.index ["taggable_id"], name: "index_taggings_on_taggable_id"
t.index ["taggable_type"], name: "index_taggings_on_taggable_type"
t.index ["tagger_id", "tagger_type"], name: "index_taggings_on_tagger_id_and_tagger_type"
t.index ["tagger_id"], name: "index_taggings_on_tagger_id"
end
create_table "tags", id: :serial, force: :cascade do |t|
t.string "name"
t.integer "taggings_count", default: 0
t.index ["name"], name: "index_tags_on_name", unique: true
end
Пытаясь решить эту проблему, я пробовал много разных вещей, таких как откат миграций, переустановка гема, изменение имени списков, использование по умолчанию, использование его на другой модели и несколько разных контроллеров. действия. Также в коде вы также увидите присутствие FriendlyID Gem.
Большое спасибо за чтение и вашу помощь.
* Чтобы временно исправить эту проблему ActsAsTaggableOn с Rails 5.2, используйте ветку из Fodoj, называемую rails-5.2. В вашем gemfile добавьте ссылку и ветку git в gem акт-as-taggable-on, а затем запустите bundle install и перезапустите сервер: *
gem 'acts-as-taggable-on', :git => 'https://github.com/Fodoj/acts-as-taggable-on', :branch => 'rails-5.2'
