Question

在我的食谱展示页面中，我有评论，用户可以删除评论。在CommentsController中我有使用此代码的destroy方法

def destroy
  @comment = Comment.find(params[:id])
  @recipe = Recipe.find(@comment.commentable_id)
  respond_to do |format|
    if @comment.destroy
      @all_comments = @recipe.comments.recent.all.paginate(page: params[:page], per_page:15)
      format.html do
        flash[:success] = "Comment successfully deleted!"
        redirect_to recipe_path(@recipe)
      end
      format.js {@recipe_comments = @all_comments}
    else
      format.html do
        flash[:danger] = "Some errors occurred!"
        redirect_to recipe_path(@recipe)
      end
      format.js
    end
  end
end

删除网址：

<%= link_to "Delete", {controller: "comments", action: "destroy", method: :delete, id: comment.id}, class: "close", remote: true %>

但是当我按下删除时出现此错误：

AbstractController::ActionNotFound (The action 'show' could not be found for CommentsController)

修改的日志：

这是我删除操作的所有日志堆栈。

Answer 1

正如您在日志中看到的那样，您的请求是＆＃39;获取＆＃39; Http动词和方法=删除作为参数传递。

更改删除网址，移动方法::从哈希中删除。

<%= link_to "Delete", {controller: "comments", action: "destroy", id: comment.id}, method: :delete, class: "close", remote: true %>
