为什么我收到此错误？

I get this error when deleting a comment_title:

删除comment_title时出现此错误:

NoMethodError in Comment titlesController#destroy

undefined method `comment_titles' for #<User:0x102e63bf8>

This is the destroy method:

这是破坏方法:

def destroy
  @comment_title = current_user.comment_titles.find(params[:id])
  @comment_title.destroy
  respond_to do |format|
    format.html {redirect_to :back}
  end
end

and the error refers to this line:

并且错误引用此行:

@comment_title = current_user.comment_titles.find(params[:id])

I don't understand what's going on here. Is it saying that current_user is nil? That doesn't make sense because I am logged in, and current_user works in other parts of my app. This also worked before, but after a lot of changes in my app, it doesn't work all of a sudden.

我不明白这里发生了什么。是说current_user是零吗?这没有意义,因为我已登录,而current_user在我的应用程序的其他部分工作。这之前也有用,但经过我的应用程序的大量更改后,它不会突然发挥作用。

What's wrong and how do I fix it?

怎么了,怎么解决?

(Please don't ask me what I did from now until when deleting worked. I've done far too much stuff for it to be helpful.)

(请不要问我从现在开始做什么,直到删除工作。我已经做了太多的事情,因为它有用。)

2 个解决方案

#1

Seems like you haven't got

好像你还没有

has_many :comment_titles

in your User model

在您的用户模型中

#2

It's saying that User objects don't have a method "comment_titles". I can't be more specific without seeing your model code but I suggest that you look there for further clues. Is there a method or association called "comment_titles"?

它说User对象没有方法“comment_titles”。如果没有看到您的型号代码,我就无法更具体,但我建议您在那里寻找更多线索。是否有称为“comment_titles”的方法或关联?
