ruby-on-rails-3 - Rails 3 UJS : Passing in params when using link_to

Question

除了ID，我们如何传入额外的参数

#we want to pass in additional params as well
<%= link_to  "bleh", like_path(answer), :add_param=>2 , :remote=>"true" ,:method=>:post %>

Answer 1

您可以将路径函数中的参数作为 url 的一部分传递。就像是:

<%= link_to "bleh", 
  like_path(:answer_id => 123, :add_param => 2), 
  :remote=> true , :method=> :post %>

# would result in something like
# yourapp.com/like/aswer/3?add_param=2

但是我认为在这种情况下您需要摆脱纯粹基于资源的路径助手。检查 documentation的想法。
