使用错误消息呈现当前视图

Question

我想呈现相同的视图，但是当它们发布评论失败时显示错误消息。

Comments.controllers

def create 
    @project = Project.find(params[:project_id]) 
    @comment = @project.comments.build(comment_params) 
    @comment.user_id = current_user.id 
     if @comment.save 
     flash[:success] = "Comment created!" 
     redirect_to @project 
    else 
     @projectboard_items = [] 
     flash[:danger] = "Sorry! your comment was not created" 
     render @project #<----- replace this line 
    end 
    end 

谢谢！

Answer 1

下要不然就把这个

format.html {redirect_to的new_comment_path，通知：“对不起！你的评论没有创建。' }
