Answer 1

您可以在rails中使用debug函数

<%= debug @user %>

Answer 2

First off, your loop is a bit strange. It seems to me that you should have

<% @user.dids.each_with_index{ |did, i| %>
  <li><%=h did %></li>
<% } %>

In your version, you are printing the entire @user.dids with each iteration.

Also, how is the class Did defined? If you are in Rails and Did is an ActiveRecord model, you should have the .to_json method available to you (options and info here ):

<% @user.dids.each_with_index{ |did, i| %>
  <li><%=h did.to_json %></li>
<% } %>

Answer 3

OK I sleep so correctly

<% @user.dids.each_with_index{ |did, i| %>
  <li><%= did.did %></li>
<% } %>
