在Rails 4中将CSS样式添加到form_tag中

Question

我遇到了使用我的html表单绑定ruby表单的问题。我绑定，但形式不显示和隐藏的CSS样式。我正在使用铁路4.2.3。我已经使用了自举宝石。

<%= form_tag users_admin_path , :method=> :post do %> 
       <%= label_tag :factory_name%> 
       <%= text_field_tag :factory_name%> 
       <%= label_tag :email%> 
       <%= text_field_tag :email %> 
       <%= label_tag :password %> 
       <%= password_field_tag :password %> 
      <%= submit_tag "Sign in", class: "btn btn-large btn-primary" %> 
      <% end %> 

这是我的html表单代码。

form class="form-horizontal"> 
<div class="col-md-6 col-md-offset-2 remove-margin"> 
      <div class="form-group"> 
       <label class="col-sm-3 control-label">User name</label> 
       <div class="col-sm-9"> 
       <input type="text" class="form-control" placeholder=""> 
       </div> 
      </div> 
      <div class="form-group"> 
       <label class="col-sm-3 control-label">Email</label> 
       <div class="col-sm-9"> 
       <input type="email" class="form-control" placeholder=""> 
       </div> 
      </div> 
      <div class="form-group"> 
       <label class="col-sm-3 control-label">Password</label> 
       <div class="col-sm-9"> 
       <input type="password" class="form-control" placeholder=""> 
       </div> 
      </div> 

       </div> 
       </div> 
      </div> 
      <div class="form-group"> 
       <label class="col-sm-3 control-label">&nbsp;</label> 
       <div class="col-sm-9"> 
       <div class="btm-btn text-center"> 
        <button type="submit" class="btn-type">Create</button> 
       </div> 
       </div> 
      </div> 
      </div> 
     </form>

<%= form_for @User, html: { :class => "form-horizontal"} do |f|%> 

       <div class="col-md-6 col-md-offset-2 remove-margin"> 
       <div class="form-group"> 
       <!-- <label class="col-sm-3 control-label">User name</label>--> 
        <%= f.label :user_name ,:class => "col-sm-3 control-label"%> 
        <div class="col-sm-9"> 
        <!--<input type="text" class="form-control" placeholder="">--> 
        <%= f.text_field :user_name, :required => true, :class =>"form-control" %> 
        </div> 
       </div> 
       <div class="form-group"> 
        <!--<label class="col-sm-3 control-label">Email</label>--> 
        <%= f.label :email,:class => "col-sm-3 control-label"%> 
        <div class="col-sm-9"> 
        <!--<input type="email" class="form-control" placeholder="">--> 
        <%= f.email_field :email, :required => true, :class =>"form-control" %> 
        </div> 
       </div> 
       <div class="form-group"> 
       <!-- <label class="col-sm-3 control-label">Password</label>--> 
       <%= f.label :password,:class => "col-sm-3 control-label"%> 
        <div class="col-sm-9"> 
        <!--<input type="password" class="form-control" placeholder="">--> 
        <%= f.password_field :password, :required => true, :class =>"form-control" %> 
        </div> 
       </div> 

       <% end %> 

       <div class="form-group"> 
       <!-- <label class="col-sm-3 control-label">&nbsp;</label>--> 
        <div class="col-sm-9"> 
        <div class="btm-btn text-center"> 
         <!--<button type="submit" class="btn-type">Create</button>--> 
         <%= f.submit class: "btn btn-large btn-primary" %> 

        </div> 
        </div> 
       </div> 


       <% end %> 
      <!--</form>--> 
      </div> 
     </div>
