ruby-on-rails - Rails : named_scope, lambda 和 block

Question

我认为下面两个是等价的:

named_scope :admin, lambda { |company_id| {:conditions => ['company_id = ?', company_id]} }

named_scope :admin, lambda do |company_id| 
  {:conditions => ['company_id = ?', company_id]}
end

但 Ruby 正在提示:

ArgumentError: tried to create Proc object without a block

有什么想法吗？

Answer 1

这是一个解析器问题。试试这个

named_scope :admin, (lambda do |company_id| 
  {:conditions => ['company_id = ?', company_id]}
end)
