Critical Conventions

Project Development Standards

• For complete projects (HTTP/microservices), install GoFrame CLI and use gf init to create project scaffolding. See Project Creation - init for details.
• Auto-generated code files (dao, do, entity) MUST NOT be manually created or modified per GoFrame conventions.
• Unless explicitly requested, do NOT use the logic/ directory for business logic. Implement business logic directly in the service/ directory.
• Reference complete project examples:
  • HTTP service best practice: user-http-service
  • gRPC service best practice: user-grpc-service

Component Usage Standards

• Before creating new methods or variables, check if they already exist elsewhere and reuse existing implementations.
• Use the gerror component for all error handling to ensure complete stack traces for traceability.
• When exploring new components, prioritize GoFrame built-in components and reference best practice code from examples.
• Database Operations MUST use DO objects (internal/model/do/), never g.Map or map[string]interface{}. DO struct fields are interface{}; unset fields remain nil and are automatically ignored by the ORM:

  // Good - use DO object
  dao.Users.Ctx(ctx).Where(cols.Id, id).Data(do.User{Uid: uid}).Update()
  
  // Good - conditional fields, unset fields are nil and ignored
  data := do.User{}
  if password != "" { data.PasswordHash = hash }
  if isAdmin != nil { data.IsAdmin = *isAdmin }
  dao.Users.Ctx(ctx).Where(cols.Id, id).Data(data).Update()
  
  // Good - explicitly set a column to NULL using gdb.Raw
  dao.Instances.Ctx(ctx).Where(cols.Id, id).Data(do.Instance{IdleSince: gdb.Raw("NULL")}).Update()
  
  // Bad - never use g.Map for database operations
  dao.Users.Ctx(ctx).Data(g.Map{cols.Uid: uid}).Update()
  

Code Style Standards

• Variable Declarations: When defining multiple variables, use a var block to group them for better alignment and readability:

  // Good - aligned and clean
  var (
      authSvc       *auth.Service
      bizCtxSvc     *bizctx.Service
      k8sSvc        *svcK8s.Service
      notebookSvc   *notebook.Service
      middlewareSvc *middleware.Service
  )
  
  // Avoid - scattered declarations
  authSvc := auth.New()
  bizCtxSvc := bizctx.New()
  k8sSvc := svcK8s.New()
  

• Apply this pattern when you have 3 or more related variable declarations in the same scope.
