From ede12f0abd65e74322dac5e8a7837d61bb480449 Mon Sep 17 00:00:00 2001 From: nutcas3 Date: Thu, 23 Apr 2026 02:50:23 +0300 Subject: [PATCH] feat: Add automation service with workflow execution, scheduling, run history, and comprehensive test coverage - Add AutomationService struct with database dependency and NewAutomationService constructor - Add AutomationFilter struct with enabled/type fields for filtering automations - Add List method with enabled/type filtering, created_at DESC ordering, and context support - Add Get method with ID lookup, gorm.ErrRecordNotFound handling, and error wrapping - Add CreateAutomationInput struct with name/description/type/enabled --- .../internal/services/automation.go | 194 ++++++++++ .../services/automation_service_test.go | 333 ++++++++++++++++++ 2 files changed, 527 insertions(+) create mode 100644 apps/api-server/internal/services/automation.go create mode 100644 apps/api-server/internal/services/automation_service_test.go diff --git a/apps/api-server/internal/services/automation.go b/apps/api-server/internal/services/automation.go new file mode 100644 index 0000000..e11635e --- /dev/null +++ b/apps/api-server/internal/services/automation.go @@ -0,0 +1,194 @@ +package services + +import ( + "context" + "errors" + "fmt" + "time" + + "gorm.io/gorm" + + "github.com/nutcas3/telecom-platform/apps/api-server/internal/database" + "github.com/nutcas3/telecom-platform/apps/api-server/internal/models" +) + +// AutomationService provides persistence and execution of workflow automations. +type AutomationService struct { + db *database.Database +} + +func NewAutomationService(db *database.Database) *AutomationService { + return &AutomationService{db: db} +} + +type AutomationFilter struct { + Enabled *bool + Type string +} + +func (s *AutomationService) List(ctx context.Context, f AutomationFilter) ([]models.Automation, error) { + q := s.db.DB.WithContext(ctx).Model(&models.Automation{}) + if f.Enabled != nil { + q = q.Where("enabled = ?", *f.Enabled) + } + if f.Type != "" { + q = q.Where("type = ?", f.Type) + } + var out []models.Automation + if err := q.Order("created_at DESC").Find(&out).Error;
