嗨,我是Rails的新手,我已经设法在Hartl的第9章结束。我有3个失败的测试来完成章节。
终端返回:

我真的不确定这里出了什么问题,因为我真的很想忠实于这个教程。有任何想法吗?谢谢西蒙。
答案 0 :(得分:1)
因为您收到以下消息:
AbstractController::ActionNotFound:
The action 'destroy' could not be found for UsersController
您必须在destroy
。
UsersController
操作
class UsersController < ApplicationController
.
.
.
def destroy
@user = User.find(params[:id])
@user.destroy
flash[:success] = 'User was deleted with success.'
redirect_to users_path
end
end
创建链接以删除每个用户。
在你的`app / views / users / index.html.erb'中,你应该有这样的东西:
<% @users.each do |user| %>
<p><%= link_to user.name, user_path(user), method: delete, confirm: 'Are you sure?' %></p>
<% end %>
希望它对你有所帮助。
