为什么我不能为yii2应用程序添加多个用户?我正在使用microsoft sql server并且yii2 app的注册代码尚未更改。当用户表中没有记录时,我可以使用yii的注册页面添加用户。 这是数据库脚本
USE [IBR]
GO
/****** Object: Table [dbo].[user] Script Date: 11/05/2016 16.51.02 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[user](
[id] [int] IDENTITY(1,1) NOT NULL,
[username] [nvarchar](255) NOT NULL,
[auth_key] [nvarchar](32) NOT NULL,
[password_hash] [nvarchar](255) NOT NULL,
[password_reset_token] [nvarchar](255) NULL,
[email] [nvarchar](255) NOT NULL,
[status] [smallint] NOT NULL DEFAULT ((10)),
[created_at] [int] NOT NULL,
[updated_at] [int] NOT NULL,
PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],

您的问题与[password_reset_token]列相似。
您对该列有唯一约束,但它允许NULL值,并且您不在此语句中插入数据,这就是为什么它将NULL视为重复键。您可以删除此字段上的唯一约束,也可以查看将唯一数据插入此字段。
