## Ch 2.1.4 建立 Posts Controller 裡的 edit

在 `app/controllers/groups_controller.rb` 加入 `edit` 這個 action

~~~~~~~~
  def edit
    @group = Group.find(params[:group_id])
    @post = @group.posts.find(params[:id])
  end

~~~~~~~~


### 補上 view

touch app/views/posts/edit.html.erb

~~~~~~~~

<div class="span12">

 <%= simple_form_for [@group,@post]  do |f| %>
    <%= f.input :content, :input_html => { :class => "input-xxlarge"} %>
    
    <div class="form-actions">   
       <%= f.submit "Submit", :disable_with => 'Submiting...', :class => "btn btn-primary" %>
    </div>
  <% end %>

</div>
