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核心组件数据校验数据校验-校验规则.md

GoFrame 框架校验组件内置了数十项常用的校验规则，校验组件是开发者最频繁使用的框架核心组件之一。 :::info 校验规则涉及到联合校验的场景时，规则中关联的 参数名称 会自动按照不区分大小写且忽略特殊字符的形式进行智能匹配。以下示例代码中我们均采用常用的结构体校验的方式，结构体属性中的 v 标签标识 validation 的缩写，用于设置该属性的校验规格。 :::

修饰规则

修饰规则本身没有任何的校验逻辑，而是修改后续功能规则的实现逻辑。

ci

  • 格式：ci

  • 说明：字段值比较在默认情况下为 区分大小写 严格匹配比较，通过 ci(Case Insensitive) 修饰规则，可以设置后续需要比较值的规则字段为 不区分大小写。如： same, different, in, not-in 等。

  • 示例：

    func Example_Rule_CaseInsensitive() {
    type BizReq struct {
        Account   string `v:"required"`
        Password  string `v:"required|ci|same:Password2"`
        Password2 string `v:"required"`
    }
    var (
        ctx = context.Background()
        req = BizReq{
            Account:   "gf",
            Password:  "Goframe.org", // Diff from Password2, but because of "ci", rule check passed
            Password2: "goframe.org",
        }
    )
    if err := g.Validator().Data(req).Run(ctx); err != nil {
        fmt.Println(err)
    }

    // output:
}

bail

需要特别注意：如果参数校验存在多条校验规则，并且规则中存在 required* 规则和 bail 修饰规则一起使用时，那么建议将 required* 校验规则放置于所有规则之前，否则 bail 校验规则的特性（校验失败即停止后续校验）有可能会引起后续规则的 required* 规则不生效。

  • 格式：bail

  • 说明：只要后续的多个校验中有一个规则校验失败则停止校验并立即返回校验结果。

  • 注意：在框架的 HTTP Server 组件中，如果采用规范路由注册方式，在其自动校验特性中将会自动开启 bail 修饰规则，开发者无需在 Req 对象中显式设置 bail。

  • 示例：

    func Example_Rule_Bail() {
    type BizReq struct {
        Account   string `v:"bail|required|length:6,16|same:QQ"`
        QQ        string
        Password  string `v:"required|same:Password2"`
        Password2 string `v:"required"`
    }
    var (
        ctx = context.Background()
        req = BizReq{
            Account:   "gf",
            QQ:        "123456",
            Password:  "goframe.org",
            Password2: "goframe.org",
        }
    )
    if err := g.Validator().Data(req).Run(ctx); err != nil {
        fmt.Println(err)
    }

    // output:
    // The Account value `gf` length must be between 6 and 16
}

foreach

  • 格式：foreach

  • 说明：用于数组参数，将待检验的参数作为数组遍历，并将后一个校验规则应用于数组中的每一项。

  • 版本：框架版本 >=v2.2.0

  • 示例：

    func Example_Rule_Foreach() {
    type BizReq struct {
        Value1 []int `v:"foreach|in:1,2,3"`
        Value2 []int `v:"foreach|in:1,2,3"`
    }
    var (
        ctx = context.Background()
        req = BizReq{
            Value1: []int{1, 2, 3},
            Value2: []int{3, 4, 5},
        }
    )
    if err := g.Validator().Bail().Data(req).Run(ctx); err != nil {
        fmt.Println(err.String())
    }

    // Output:
    // The Value2 value `4` is not in acceptable range: 1,2,3
}

功能规则

功能规则实现特定的校验逻辑，框架内置了非常丰富强大的内置校验规则。

    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.

What it does

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.

Frequently asked

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.
