Mysql Rails 5：如何使用Rails（HTML5）在数据库中插入记录

注：我已经阅读了以下内容：

我使用的是Rails 5

请告诉我如何在数据库中插入记录

我正在使用MYSQL，下面是我的表结构，它是db文件夹中正确的schema.rb

 ActiveRecord::Schema.define(version: 20161107113839) do

  `create_table "allusers", force: :cascade, options: "ENGINE=InnoDB `DEFAULT   CHARSET=latin1" do |t|`
  t.string   "username",    limit: 50, null: false
  t.string   "email",       limit: 50
  t.string   "password",    limit: 50
  t.string   "likedvideos", limit: 50
  t.datetime "created_at",             null: false
  t.datetime "updated_at",             null: false
  end

end

这是我的控制器文件user1\u Controller.rb

 class User1Controller < ApplicationController
 def user1index
 end

---

您的表单应该如下所示：

 <%= form_for @user1 do |u| %>
 <%= u.label :username %>:
 <%= u.text_field :username  %><br />
 <%= u.label :email %>:
 <%= u.text_field :email %><br />
 <%= u.label :password %>:
 <%= u.password_field :password %><br />
 <%= u.label :liked_videos %>:
 <%= u.text_field :liked_videos%><br />
 <%= u.submit %>
<% end %>

请编辑您的问题并发布实际的错误消息，您对发生的情况的描述有点难以理解。是rails 3还是rails 5？我很困惑，Rails 5 sry纠正了它

 <form <% @user1,:action => :new, :method => :post %> >
    username: <input type="text" name="username" /><br />
    email: <input type="text" name="email" /><br/>
    password:<input type="password" name="password" /><br/>
    likedvideos: <input type="text" name="likedvideos" /><br/>

  </form>
