feat: add duplicate workflow name validation and localization support

[winfredLIN]

• Introduced a new error for duplicate data export workflow names in the business logic.
• Enhanced the DMSController to return a localized error message when a duplicate name is detected.
• Implemented a method in the WorkflowRepo to check for existing workflow names.
• Updated localization files to include messages for duplicate workflow name errors in both English and Chinese.

⚡ Recommended focus areas for review 错误处理 在检测到重复工单名称错误时，将错误信息本地化后返回。建议复查此处是否与后续错误码映射和整体异常处理保持一致，确保错误包装的一致性。 if errors.Is(err, biz.ErrDataExportWorkflowNameDuplicate) { return NewErrResp(c, errors.New(locale.Bundle.LocalizeMsgByCtx(c.Request().Context(), locale.DataExportWorkflowNameDuplicateErr)), apiError.BadRequestErr) } 错误包装 在返回添加工单错误时，使用 fmt.Errorf 的 %w 格式包裹错误。建议确认该错误包装方式是否与全局错误处理策略一致。 return nil, fmt.Errorf("add data export workflow failed: %w", err) 重复校验逻辑 在查询重复工单名称时，事务和查询逻辑的实现需要在高并发场景下确保数据一致性。建议对查询条件和事务处理进行复查以防误判。 func (d *WorkflowRepo) IsDataExportWorkflowNameDuplicate(ctx context.Context, projectUID, workflowName string) (bool, error) { var count int64 if err := transaction(d.log, ctx, d.db, func(tx *gorm.DB) error { if err := tx.WithContext(ctx).Model(&model.Workflow{}). Where("project_uid = ? AND name = ?", projectUID, workflowName). Count(&count).Error; err != nil { return fmt.Errorf("failed to check workflow name duplicate: %v", err) } return nil }); err != nil { return false, err } return count > 0, nil }

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	优化错误包装 建议使用 %w 替换 %v 来包装错误，以便保留错误链信息，便于追踪根本原因。此外，这有助于与其他地方采用错误包装一致，保证错误处理的一致性。 internal/dms/storage/workflow.go [50-54] if err := tx.WithContext(ctx).Model(&model.Workflow{}). Where("project_uid = ? AND name = ?", projectUID, workflowName). Count(&count).Error; err != nil { - return fmt.Errorf("failed to check workflow name duplicate: %v", err) + return fmt.Errorf("failed to check workflow name duplicate: %w", err) } Suggestion importance[1-10]: 6 __ Why: The suggestion improves error wrapping by replacing %v with %w, retaining error chain information, but it only touches a minor stylistic issue.
