将css rails登录表单迁移到bootstrap

需要帮助迁移到引导

引导听起来很简单，只需将所有SCS和样本粘贴即可。但我不知道如何在引导代码中插入“@user，url:signup_path”或替换以在rails应用程序中工作

更新： 引导程序如下所示：

<%= form_for(@user) do |f| %>
  <%= render 'shared/error_messages', object: @user %>
  <div class="input-group">
      <span class="input-group-addon" id="basic-addon1">@</span>
  <%= f.label :name %>
  <%= f.text_field :name, class: 'form-control' %>
  </div>

  <div class="input-group">
      <span class="input-group-addon" id="basic-addon1">@</span>
  <%= f.label :email %>
  <%= f.email_field :email, class: 'form-control' %>
   </div>

  <div class="input-group">
      <span class="input-group-addon" id="basic-addon1">@</span>
  <%= f.label :password %>
  <%= f.password_field :password, class: 'form-control' %>
  </div>

  <div class="input-group">
      <span class="input-group-addon" id="basic-addon1">@</span>
  <%= f.label :password_confirmation %>
  <%= f.password_field :password_confirmation, class: 'form-control' %>
  </div>

  <div class="input-group">
      <span class="input-group-addon" id="basic-addon1">@</span>
  <%= f.submit yield(:button_text), class: "btn btn-primary" %>
  </div>

<% end %>

类似这样的内容：

<%= form_for(@user, url: signup_path) do |f| %>
  <div class="input-group input-group-lg">
   <span class="input-group-addon" id="sizing-addon1">@</span>
   <%= f.input :name,  input_html: {class: 'form-control'}, placeholder: 'Name' %>
 </div>

 <div class="input-group">
  <span class="input-group-addon" id="sizing-addon2">@</span>
  <%= f.input :email,  input_html: {class: 'form-control'}, placeholder: 'Email' %>
 </div>

 <div class="input-group">
  <span class="input-group-addon" id="sizing-addon3">@</span>
  <%= f.password_field :password,  input_html: {class: 'form-control'}, placeholder: 'Password' %>
 </div>
 <%= f.submit "Create my account", class: "btn btn-primary" %>
<% end %>
