GoFrame v2 development skill. Use only when the target Go project uses or is explicitly adopting GoFrame v2: the nearest go.mod requires github.com/gogf/gf/v2, existing Go files import github.com/gogf/gf/v2 or any github.com/gogf/gf/v2/... component package, or the user asks to scaffold, migrate, or build with GoFrame. Trigger for GoFrame-backed Go work such as APIs/controllers/services, middleware, routing/config, ORM/DAO/DO/entity/database operations, gf CLI/codegen, HTTP/gRPC services, and microservice conventions. Do not trigger for generic Go projects without GoFrame evidence, frontend-only work, shell scripts, or unrelated infrastructure tasks.

references核心组件数据库ORMORM链式操作ORM链式操作-时间维护时间维护-整型字段.md

从v2.8版本开始,如果时间字段created_at、 updated_at、 deleted_at为整型字段,ORM组件会自动识别支持,并写入秒级的时间戳数值。

示例SQL

这是后续示例代码中用到的MySQL表结构。

CREATE TABLE `user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(45) NOT NULL,
  `status` tinyint DEFAULT 0,
  `created_at` int(10) unsigned DEFAULT NULL,
  `updated_at` int(10) unsigned DEFAULT NULL,
  `deleted_at` int(10) unsigned DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE IF NOT EXISTS `user_detail` (
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
    `address` varchar(45) NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

:::tip 如果您尝试测试查看ORM操作执行的SQL语句,建议您打开debug模式(相关文档:调试模式),SQL语句将会自动打印到日志输出。 :::

created_at 写入时间

在执行 Insert/InsertIgnore/BatchInsert/BatchInsertIgnore 方法时自动写入该时间,随后的更新/删除操作不会引起created_at字段内容的改变。 :::warning 需要注意的是 Replace 方法也会更新该字段,因为该操作相当于删除已存在的旧数据并重新写一条数据。 :::

// INSERT INTO `user`(`name`,`created_at`,`updated_at`,`deleted_at`) VALUES('john',1731481488,1731481488,0)
g.Model("user").Data(g.Map{"name": "john"}).Insert()

// INSERT IGNORE INTO `user`(`id`,`name`,`created_at`,`updated_at`,`deleted_at`) VALUES(10000,'john',1731481518,1731481518,0) 
g.Model("user").Data(g.Map{"id": 10000, "name": "john"}).InsertIgnore()

// REPLACE INTO `user`(`id`,`name`,`created_at`,`updated_at`,`deleted_at`) VALUES(10000,'john',1731481747,1731481747,0)
g.Model("user").Data(g.Map{"id": 10000, "name": "john"}).Replace()

// INSERT INTO `user`(`id`,`name`,`created_at`,`updated_at`,`deleted_at`) VALUES(10001,'john',1731481766,1731481766,0) ON DUPLICATE KEY UPDATE `id`=VALUES(`id`),`name`=VALUES(`name`),`updated_at`=VALUES(`updated_at`),`deleted_at`=VALUES(`deleted_at`)
g.Model("user").Data(g.Map{"id": 10001, "name": "john"}).Save()

deleted_at 数据软删除

当软删除存在时(即deleted_at字段存在时),所有的查询语句都将会自动加上 deleted_at 的条件。

// UPDATE `user` SET `deleted_at`=1731481948 WHERE (`id`=10) AND `deleted_at`=0
g.Model("user").Where("id", 10).Delete()

查询的时候会发生一些变化,例如:

// SELECT * FROM `user` WHERE (id>1) AND `deleted_at`=0
g.Model("user").Where("id>?", 1).All()

可以看到当数据表中存在 deleted_at 字段时,所有涉及到该表的查询操作都将自动加上 deleted_at=0 的条件。

updated_at 更新时间

在执行 Save/Update 方法时自动写入该时间。需要注意的是 Replace 方法也会更新该字段,因为该操作相当于删除已存在的旧数据并重新写一条数据。 :::info 如果同时存在deleted_at软删除字段,那么更新操作语句中同样会出现deleted_at 的条件。 :::

// UPDATE `user` SET `name`='john guo',`updated_at`=1731481821 WHERE (`name`='john') AND `deleted_at`=0
g.Model("user").Data(g.Map{"name" : "john guo"}).Where("name", "john").Update()

// UPDATE `user` SET `status`=1,`updated_at`=1731481895 WHERE `deleted_at`=0 ORDER BY `id` ASC LIMIT 10
g.Model("user").Data("status", 1).OrderAsc("id").Limit(10).Update()

// INSERT INTO `user`(`id`,`name`,`created_at`,`updated_at`,`deleted_at`) VALUES(1,'john guo',1731481915,1731481915,0) ON DUPLICATE KEY UPDATE `id`=VALUES(`id`),`name`=VALUES(`name`),`updated_at`=VALUES(`updated_at`),`deleted_at`=VALUES(`deleted_at`)
g.Model("user").Data(g.Map{"id": 1, "name": "john guo"}).Save()

联表查询的场景

如果关联查询的几个表都启用了软删除特性时,会发生以下这种情况,即条件语句中会增加所有相关表的软删除时间判断。

// SELECT * FROM `user` AS `u` LEFT JOIN `user_detail` AS `ud` ON (ud.id=u.id) WHERE (`u`.`id`=10) AND `u`.`deleted_at`=0 LIMIT 1
g.Model("user", "u").LeftJoin("user_detail", "ud", "ud.id=u.id").Where("u.id", 10).One()

控制写入时间粒度

本章节的时间字段数值写入默认是秒级时间戳,但如果我们想要控制时间写入的粒度,写入毫秒级时间戳怎么做呢?我们可以使用SoftTimeOption。

    The skill provides a comprehensive development guide and code examples for the GoFrame v2 framework. While highly informative for Go developers, it contains several examples with hardcoded placeholder secrets, tokens, and specific local file paths to sensitive configuration files (like Kubernetes credentials). These elements are provided for demonstration purposes but represent insecure practices if used in production without modification.

README badge

README badge for gogf/skills

Provides instruction and conventions for developing with GoFrame v2, a modular Go framework for building HTTP and gRPC services, microservices, and database operations using its ORM, CLI tooling, and project scaffolding. Use this skill when the target project has GoFrame v2 as a dependency or when the user requests scaffolding, migrations, or service development with GoFrame conventions.

Generated from the current SKILL.md.

When should I use this skill?
Use this skill only when your Go project uses GoFrame v2, indicated by github.com/gogf/gf/v2 in go.mod or imports. Do not use for generic Go projects, frontend work, or infrastructure tasks unrelated to GoFrame.
Should I manually set created_at and updated_at fields?
No. GoFrame automatically writes created_at on insert and updated_at on insert/update/save. Manually setting these fields is redundant and violates project conventions.
What should I use for database operations instead of g.Map?
Always use DO objects from internal/model/do/. DO struct fields are interface{}, unset fields remain nil and are automatically ignored by the ORM.
How does soft delete work in GoFrame?
Call Delete() on the DAO; GoFrame automatically converts it to UPDATE SET deleted_at = NOW(). Queries automatically filter out soft-deleted rows without requiring manual WhereNull conditions.
Where should I implement business logic?
Implement business logic directly in the service/ directory. Do not use the logic/ directory unless explicitly requested.
