尝试在 RoR 应用程序上从我的数据库访问offices.json，但出现了这个奇怪的错误。似乎无法在网上找到任何可以告诉我发生了什么的东西。有什么建议么？似乎这个错误影响了几个模型，而由于某种原因，当我尝试通过浏览器加载 json 文件时，其他模型工作正常。
Showing /home/terence/Dropbox/ruby/rails_projects/techdata/app/views/offices/index.json.jbuilder where line #3 raised:
/home/terence/Dropbox/ruby/rails_projects/techdata/app/views/offices/index.json.jbuilder:3: syntax error, unexpected tIDENTIFIER, expecting keyword_end
json.url office_url(office, format: :json)
Extracted source (around line #3):
1 json.array!(@offices) do |office|
2 json.extract! office,
3 json.url office_url(office, format: :json)
4 end
办公室.rb：
class Office < ActiveRecord::Base
belongs_to :city
belongs_to :company
end
