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.

创建带错误码的error

NewCode/NewCodef

  • 说明:功能同New/Newf方法,用于创建一个自定义错误信息的error对象,并包含堆栈信息,并增加错误码对象的输入。

  • 格式:

    // NewCode creates and returns an error that has error code and given text.
    NewCode(code gcode.Code, text ...string) error
    
    // NewCodef returns an error that has error code and formats as the given format and args.
    NewCodef(code gcode.Code, format string, args ...interface{}) error
  • 实例:

    func ExampleNewCode() {
        err := gerror.NewCode(gcode.New(10000, "", nil), "My Error")
        fmt.Println(err.Error())
        fmt.Println(gerror.Code(err))
    
        // Output:
        // My Error
        // 10000
    }
    
    func ExampleNewCodef() {
        err := gerror.NewCodef(gcode.New(10000, "", nil), "It's %s", "My Error")
        fmt.Println(err.Error())
        fmt.Println(gerror.Code(err).Code())
    
        // Output:
        // It's My Error
        // 10000
    }

WrapCode/WrapCodef

  • 说明:功能同Wrap/Wrapf方法,用于包裹其他错误error对象,构造成多级的错误信息,包含堆栈信息,并增加错误码参数的输入。

  • 格式:

    // WrapCode wraps error with code and text.
    // It returns nil if given err is nil.
    WrapCode(code gcode.Code, err error, text ...string) error
    
    // WrapCodef wraps error with code and format specifier.
    // It returns nil if given `err` is nil.
    WrapCodef(code gcode.Code, err error, format string, args ...interface{}) error
  • 示例:

    func ExampleWrapCode() {
        err1 := errors.New("permission denied")
        err2 := gerror.WrapCode(gcode.New(10000, "", nil), err1, "Custom Error")
        fmt.Println(err2.Error())
        fmt.Println(gerror.Code(err2).Code())
    
        // Output:
        // Custom Error: permission denied
        // 10000
    }
    
    func ExampleWrapCodef() {
        err1 := errors.New("permission denied")
        err2 := gerror.WrapCodef(gcode.New(10000, "", nil), err1, "It's %s", "Custom Error")
        fmt.Println(err2.Error())
        fmt.Println(gerror.Code(err2).Code())
    
        // Output:
        // It's Custom Error: permission denied
        // 10000
    }

NewCodeSkip/NewCodeSkipf

  • 说明:功能同NewCode/NewCodef,用于创建一个带错误码的error对象,但忽略部分堆栈信息(按照当前调用方法位置往上忽略)。

  • 格式:

    // NewCodeSkip creates and returns an error which has error code and is formatted from given text.
    // The parameter `skip` specifies the stack callers skipped amount.
    func NewCodeSkip(code, skip int, text string) error
    
    // NewCodeSkipf returns an error that has error code and formats as the given format and args.
    // The parameter `skip` specifies the stack callers skipped amount.
    func NewCodeSkipf(code, skip int, format string, args ...interface{}) error

WrapCodeSkip/WrapCodeSkipf

  • 说明:功能同 WrapCodeSkip/WrapCodeSkipf,用于包裹一个带错误码的 error 对象,但忽略部分堆栈信息(按照当前调用方法位置往上忽略)。

  • 格式:

    // WrapCodeSkip wraps error with code and text.
    // It returns nil if given err is nil.
    // The parameter `skip` specifies the stack callers skipped amount.
    func WrapCodeSkip(code gcode.Code, skip int, err error, text ...string) error
    
    // WrapCodeSkipf wraps error with code and text that is formatted with given format and args.
    // It returns nil if given err is nil.
    // The parameter `skip` specifies the stack callers skipped amount.
    func WrapCodeSkipf(code gcode.Code, skip int, err error, format string, args ...interface{}) error

Code

  • 说明:获取错误对象中的错误码。该方法会递归获取,如果当前错误对象不存在错误码时,该方法会追溯查找其上一级错误对象的错误码,以此类推。当给定的error参数不带有错误码信息时,该方法返回预定义的错误码gcode.CodeNil。

  • 格式:

    // Code returns the error code of `current error`.
    // It returns `CodeNil` if it has no error code neither it does not implement interface Code.
    func Code(err error) gcode.Code
  • 示例:

    func ExampleCode() {
        err1 := gerror.NewCode(gcode.CodeInternalError, "permission denied")
        err2 := gerror.Wrap(err1, "operation failed")
        fmt.Println(gerror.Code(err1))
        fmt.Println(gerror.Code(err2))
    
        // Output:
        // 50:Internal Error
        // 50:Internal Error
    }

HasCode

  • 说明:该方法判断给定的错误对象中是否包含指定的错误码。与Code方法类似,该方法也会追溯查找上一级错误的错误码。

  • 格式:

    // HasCode checks and reports whether `err` has `code` in its chaining errors.
    func HasCode(err error, code gcode.Code) bool
  • 示例:

    func ExampleHasCode() {
        err1 := gerror.NewCode(gcode.CodeInternalError, "permission denied")
        err2 := gerror.Wrap(err1, "operation failed")
        fmt.Println(gerror.HasCode(err1, gcode.CodeOK))
        fmt.Println(gerror.HasCode(err2, gcode.CodeInternalError))
    
        // Output:
        // false
        // true
    }

    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.
