How to retrieve the hash values in the views in rails

I have an action in the controller:

def user_detail
    @user_detail = UserDetail.find_by_id(11)
end

And 开发者_运维知识库in the view:

<%= @user_detail -%> // displays me like #

I am trying to retrieve the contents of @user_detail: actually the hash contains {:empid=>"11111", :prjtname=>"aaaaa", :prjtrole=>"Developer"}

How do I display the user detail's empid and other values?

Since I know what question you asked earlier, I think this is the syntax you actually want to use:

<%= @user_detail.additional_info[:empid] %>

Unless of course you renamed the name of the hash :)

Another approach, if you want all the content from the hash but the keys varies from each record, you could loop through them like this:

<% @user_detail.additional_info.each_pair do |key, value| %>
  <p>Key: <%= key %> Value: <%= value %></p>
<% end %>

---

To get simple debug output like the example you posted, this will handle it:

<%= @user_detail.inspect %>

---

try this <%= @user_detail.emplid %> <%= @user_detail.prjtname %> <%= @user_detail.prjtr %>

---

More of an extraction from @dln's answer

try using

<%= @user_detail[:emplid] %>
<%= @user_detail[:prjtname] %>
<%= @user_detail[:prjtr] %>

Hope this solves your prob
