引導模式窗體犯兩次

我有一個模式窗體：引導模式窗體犯兩次

<div id="commentModal" class="modal hide fade"> 
    <div class="modal-body"> 
    <%= form_for(Comment.new, remote: true, html: {"data-type" => :json}, :validate => true) do |f| %> 
     <%= f.hidden_field(:illustration_id, :value => @illustration.id) %> 
     <%= f.hidden_field(:user_id, :value => current_user.id) %> 
     <%= f.text_area(:comment, :id => "comment_message") %> 
     <%= f.submit "Submit", :class => 'btn btn-custom-primary' %> 
    <% end %> 

    </div> 
</div>

當我提交的評論被添加到數據庫兩次，這裏是日誌。你明白爲什麼會發生這種情況嗎？我可以提供任何其他代碼來幫助嗎？

按照要求，評論控制器創建方法：

def create 
    @comment = Comment.new(params[:comment]) 

    respond_to do |format| 
     if @comment.save 
     format.html { redirect_to @comment, notice: 'Comment was successfully created.' } 
     format.json { render json: @comment, status: :created, location: @comment } 
     else 
     format.html { render action: "new" } 
     format.json { render json: @comment.errors, status: :unprocessable_entity } 
     end 
    end 
    end

和新方法：

def new 
    @comment = Comment.new 

    respond_to do |format| 
     format.html # new.html.erb 
     format.json { render json: @comment } 
    end 
    end

你可以發佈你的控制器代碼嗎？ –

@ErminDedovic，補充說。 –

你有任何發生的動作（過濾器）之前或之後遞交？ –
