Question

我已经设置了回形针，它与我自己创建的模型一起正常工作我试图用模型做同样的事情，模型由名为 acts_as_commentable_with_threading 的gem创建但是它永远不会保存存储图片的file_name。但它像往常一样保存评论这真是奇怪，它只是不会采取纸夹文件上传。

为什么？

models / comment.rb （当然，我已在评论表中迁移了必需的列）

attr_accessible :comment_icon

has_attached_file :comment_icon,
    :styles => {
    :thumb=> "100x100>",
    :small  => "400x400>" }

视图/用户/ show.html.erb

<%= render 'comment', :user => @user %>

视图/用户/ _comment.html.erb

<%=form_for :users, url: url_for( :controller => :users, :action => :add_comment ) do |f| %>

    <div class="field">
      <%= f.label :body %><br />
      <%= f.text_field :body %>
    </div>
    <div class="field">
    <%= f.file_field :comment_icon %>
    </div>
  <div class="actions">
    <%= f.submit %>
  </div>

<% end %>

更新：

users_controller.rb

def add_comment
    @user = User.find_by_username(params[:id])
    @user_who_commented = current_user
    @comment = Comment.build_from( @user, @user_who_commented.id, params[:users][:body] )
    @comment.save
    redirect_to :controller => 'users', :action => 'show', :id => @user.username
    flash[:notice] = "comment added!"
end




def delete_comment
    @comment = Comment.find(params[:id])

    if current_user.id == @comment.user_id
        @comment.destroy
        flash[:notice] = "Deleted!"
    else
        flash[:notice] = "Sorry, you can't delete this comment"
    end
    redirect_to :controller => 'users', :action => 'show', :id => params[:username]
end

models / comment.rb（由acts_as_commentable_with_threading自动创建）

这是评论模型的一部分。当它在我的用户操作中添加评论时，这是否重要？

  # Helper class method that allows you to build a comment
  # by passing a commentable object, a user_id, and comment text
  # example in readme
  def self.build_from(obj, user_id, comment)
    c = self.new
    c.commentable_id = obj.id
    c.commentable_type = obj.class.base_class.name
    c.body = comment
    c.user_id = user_id
    c
  end

尝试在@comment.save操作中add_comment之前添加此行：

@comment.comment_icon = params[:users][:comment_icon]

如何将paperclip启用为acts_as_commentable_with_threading？
