Question

我在Ruby on Rails中遇到了用户注册表单的问题。只需使用用户名，电子邮件和密码，我就可以使用它。但是，当我尝试添加名字，姓氏和邮政编码的字段时，它会停止将任何数据插入数据库，然后重定向回到注册表单。

我以正确的方式生成迁移并迁移数据库 - 表单仍然无效。

然后我完全删除了数据库，并在包含所有字段的情况下重新创建它，但它仍然无效。使用正确的字段正确生成数据库，我不确定断开连接的位置。

我正在使用ruby 2.3.1。

用户控制器：

class UsersController < ApplicationController

  def new
  @user = User.new
end

def create 
  @user = User.new(user_params) 
  if @user.save 
    session[:user_id] = @user.id 
    redirect_to '/home' 
  else 
    redirect_to '/register' 
  end 
end

private
  def user_params
    params.require(:user).permit(:username, :email, :password, :location, :fname, :lname)
  end

end

用户模型：

class User < ApplicationRecord

    has_secure_password 

end

用户/新表格：

  <div class="container">      
  </div>

<div id="contact" class="container-fluid bg-grey">

  <h2 class="text-center">Create An Account</h2>
  <form>

        <%= form_for(@user) do |f| %>
        <%= f.text_field :username, :placeholder => "Username" %>
      <%= f.email_field :email, :placeholder => "Email" %>
      <%= f.password_field :password, :placeholder => "Password" %><br/><br/>
        <%= f.text_field :fname, :placeholder => "First Name" %>
        <%= f.text_field :lname, :placeholder => "Last Name" %>
        <%= f.number_field :location, :placeholder => "ZIP Code (US Only)" %><br/><br/>
      <%= f.submit "Create an Account", class: "btn-submit" %>
    <% end %>

</div>

 </ul>
</nav>
</body>
</html>

创建用户迁移：

class CreateUsers < ActiveRecord::Migration[5.0]
  def change
    create_table :users do |t|
      t.string :username
      t.string :email
      t.string :password_digest
      t.numeric :location
      t.string :fname
      t.string :lname

      t.timestamps
    end
  end
end

我明白了。额外的表单标签弄乱了表单提交。一旦我从Ruby表单代码上方删除<form>，它就可以了。感谢回复的人。
