Question

我试图在RoR中的each对象/列表上调用ActiveRecord，如下面的代码块所示。

 41 Then /I should (not )?see movies with ratings: (.*)/ do |not_see, rating_li>
 42   @movies = Movie.where(:rating, rating_list.split(", "))
 43   rating_list.split(",").map do |x|
 44     x.strip
 45   end.each do |rating|
 46     if not_see
 47       @movies.each do |movie|
 48         @movie.title
 49       end
 50     else
 51       puts "hello"
 52     end
 53   end
 54 end

这会产生以下错误消息：

And I should not see movies with ratings: G, PG-13, NC-17 # features/step_definitions/movie_steps.rb:41
  unsupported: Symbol (RuntimeError)
  ./features/step_definitions/movie_steps.rb:47:in `block (2 levels) in <top (required)>'
  ./features/step_definitions/movie_steps.rb:45:in `each'
  ./features/step_definitions/movie_steps.rb:45:in `/I should (not )?see movies with ratings: (.*)/'
  features/filter_movie_list.feature:33:in `And I should not see movies with ratings: G, PG-13, NC-17'

删除上面代码中的行47可以消除错误。这是为什么？据我所知，所有这些都是有效的Ruby代码。我错过了什么？

谢谢大家！

Answer 1

导致错误的代码行是行42。对where的调用应该是：

Movie.where(:rating => rating_list.split(","))

"=>"而非","

不支持：Rails上的黄瓜中的符号
