Question

我正在学习rails并使用网络指南构建身份验证系统，并遵循railscasts教程。

我现在已经站稳脚跟，如果可能的话需要一些帮助。

当我尝试编辑用户个人资料时，收到一条错误消息，告诉我由于已经收集了电子邮件和用户名等字段，因此无法创建帐户。

环顾四周似乎与我的编辑表单提交方式有关，但我无法解决！

任何帮助都将不胜感激。

Users_controller.rb

def edit
 @user = User.find(params[:id])
end

def update
  @user = User.find(params[:id])
  if @user.update_attributes(user_params)
  flash[:success] = "Profile updated"
  redirect_to @user
  else
    render 'edit'
  end
end

edit.html.erb ＆lt;％= form_for：user，url：＆＃39; / users＆＃39;做| f | ％GT;

            <form class="m-t" role="form" action="#">
                <div class="form-group">
                  <%= f.label :name %>

Answer 1

等我验证错了。刚发现它。

<%= form_for :user, url: '/users' do |f| %>

这不会使用@user对象，这意味着rails认为您正在尝试创建用户。

将其切换为

<%= form_for @user do |f| %>

Rails还会推断发布的正确位置，因此您不再需要url选项。

Rails在更新用户详细信息时尝试创建用户
