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.

SetTimeZone 设置全局时区

package main

import (
    "fmt"
    "time"

    "github.com/gogf/gf/v2/os/gtime"
)

func main() {
    // 设置进程全局时区
    err := gtime.SetTimeZone("Asia/Tokyo")
    if err != nil {
        panic(err)
    }

    // 使用gtime获取当前时间
    fmt.Println(gtime.Now().String())

    // 使用标准库获取当前时间
    fmt.Println(time.Now().String())
}

执行后,输出结果为:

2023-01-06 15:27:38
2023-01-06 15:27:38.753909 +0900 JST m=+0.002758145

时区设置注意事项

SetTimeZone 方法多次调用报错

SetTimeZone 方法只允许全局设置一次时区,如果多次调用,并且设置的时区不一样,后续调用将会失败,并返回 error。

业务项目中, time 包初始化问题

程序时区的全局设置必须要在标准库的 time 包 import 之前调用,因为标准库的 time 包在 import 时会执行初始化,之后无法再全局修改程序时区,只能通过 ToLocation 方法(或者标准库 In 方法)对特定时间对象执行时区转换。对时间对象使用 ToLocation 转换的例子:

package main

import (
    "fmt"
    "time"

    "github.com/gogf/gf/v2/os/gtime"
)

func main() {
    // 设置进程全局时区
    err := gtime.SetTimeZone("Asia/Tokyo")
    if err != nil {
        panic(err)
    }

    // 使用gtime获取当前时间
    fmt.Println(gtime.Now())

    // 使用标准库获取当前时间
    fmt.Println(time.Now())

    // 对特定时间对象执行时区转换
    local, err := time.LoadLocation("Asia/Shanghai")
    if err != nil {
        panic(err)
    }
    fmt.Println(gtime.Now().ToLocation(local))
}

执行后,终端输出:

2023-01-06 15:37:38
2023-01-06 15:37:38.753909 +0900 JST m=+0.002758145
2023-01-06 14:37:38

在业务项目中,往往在 main 包之前会有很多业务的包 import,会引起 time 包的初始化问题。因此,如果需要全局设置时区,建议通过一个独立的包来调用 SetTimeZone 方法,并且在 main 包的最开头执行 import 规避 time 包初始化的问题。例如:

package main

import (
    _ "boot/time"

    "fmt"
    "time"
)

func main() {
    // 使用gtime获取当前时间
    fmt.Println(gtime.Now().String())

    // 使用标准库获取当前时间
    fmt.Println(time.Now().String())
}

    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.
