我有一个angular / rails应用程序，用户可以在其中搜索电影，然后将该电影添加到他们的监视列表中。
这是角度的创建函数，
$scope.movieCrew = response.credits.crew
$scope.movieCast = response.credits.cast
我在演员范围内有演员和工作人员数据，
def create
@movie = Movie.find_or_create_by movie_params
current_user.movies << @movie
redirect_to :root
current_user.followers.each { |follower| @movie.crete_activity(key: 'movie.create', owner: current_user, recipient: follower) }
end
private
def movie_params
params.require(:movie).permit(
:title,
:image,
:imdb_rating,
:release_date,
:movie_id,
:backdrop
:crew,
:cast
)
end
这些范围返回多个对象，因为涉及多个actor等。
我有一个movies_controller.rb，它有一个像这样的创建函数，
create_table "movies", force: :cascade do |t|
t.string "title"
t.string "release_date"
t.string "image"
t.integer "user_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "movie_id"
t.string "backdrop"
t.string "crew"
t.string "cast"
end
我的电影模型看起来像这样，
{"id":26,"title":"The Neon Demon","release_date":"2016-01-21","image":"/gVB7zbrsk9TtLoVI4qob97q9v07.jpg","user_id":null,"created_at":"2016-01-07T12:31:49.956Z","updated_at":"2016-01-07T12:31:49.956Z","movie_id":"301365","backdrop":"/lSojrYBHLwiQQq6xr9Mec9f8wLM.jpg","crew":null,"cast":null}
当我运行动作时，会创建电影记录

但是船员和演员的价值都是空的。
我已经检查了我的rails控制台，看看创建电影时会发生什么，
parameters正如您所看到的，movie具有正确的值，即release_date，title，image，crew，cast等。但它不会将对象存储在其中。此外，我不确定为什么parameters值中的imdbRating值会重复{{1}}所需的所有数据。
所以我的问题是，如何存储工作人员的对象并投射到我的电影记录中？
