I guess the title is self explanatory...how do I make only authenticated users to create a user with devise?
when I try to add a new one (when authenticated), devise says that I m alreade authenticated
any workaround for this?
thanks a lot

编辑:根据要求,我的代码

<<>strong>user form

<% if @user == current_user %>
<i class="icon-info-sign"> </i><i>Após alterar seus dados, você terá de fazer login novamente</i>
<% end %>

<%= form_for(@user, :html => { :class => "well form-horizontal"}) do |f| %>
  <% if @user.errors.any? %>
    <div class="alert alert-error">
      <h2><%= pluralize(@user.errors.count, "erro") %> 
        <% if @user.errors.count == 1 %> impede 
          <% else %>
            impedem
        <% end %>
      a continuação:</h2>

      <ul>
      <% @user.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>


<label>Nome</label><%= f.text_field :nome %>
<label>E-mail</label><%= f.email_field :email %>

<% if @user == current_user or @user.created_at == nil%>
  <label>Senha</label><%= f.password_field :password %>
<% end %>

<div>
<br />
<button class="btn" type="submit">
    Salvar alterações
</button>

</div>

<% end %>

<>>部分用户控制器

    @users = User.all
