Rails - Easy way to display all fields in view

Question

OK I'm sure I'm missing something here, but please forgive me I'm new to Rails.

Is there some way in Rails to display all the fields for an object rather than specifying each?

In my show.html template rather than going

<p>Name: <%=h @user.full_name %></p>
<p>Email: <%=h @user.email %></p>

I just want a oneliner to do this without having to type out each of the 15 or so fields I have. Its an admin page so its fine if all the fields are shown (id, created_at, etc.) If this was PHP it would take me about 5 secs using foreach, but I've googled (on the wrong things obviously) for an hour with no luck.

Thanks!

I suppose you want to display all attributes of a row from database table which is defined as ActiveRecord model. You can use class method column_names (every ActiveRecord model has it), which returns names of table columns in an array.

<%= User.column_names.collect { |col_name| "#{col_name.capitalize}: <p>#{@user[col_name]}</p>" }.join("\n") %>

Something like

<% for attribute in @user.attributes.keys %>
  <p><%= attribute.humanize %> <%= @user.attributes[attribute].to_s %></p>
<% end %>

could do the trick.

<%= debug @user %>

simple way to show the object... that is what I usually use anyway!
