父部门不存在

Error message

父部门不存在

What it means

buildAncestors looks up the parent department to compose the ancestor ID chain for a new/updated department. When the given parentId does not exist in sys_department, GORM returns record-not-found and the service replaces it with this clearer error. It prevents creating departments pointing at non-existent parents.

Solutions

1. Verify the parentId exists (refresh the department tree in the frontend and re-submit)
2. If creating a top-level department, send parentId=0 instead of a stale ID
3. Check data-permission filters aren't hiding the parent row for the current user
4. Wrap parent+child creation in one transaction to avoid the parent disappearing mid-operation

Example fix

// before
await createDepartment({ name: 'B', parentId: oldId })
// after
const parent = await getDepartment(oldId)
if (!parent) throw new Error('parent missing; refresh tree')
await createDepartment({ name: 'B', parentId: parent.ID })

var count int64
global.GVA_DB.Model(&system.SysDepartment{}).Where("id = ?", parentId).Count(&count)
if parentId != 0 && count == 0 {
    return errors.New("parent department does not exist")
}

if err := deptService.CreateSysDepartment(ctx, dept); err != nil {
    if err.Error() == "父部门不存在" {
        // refresh tree data and ask user to reselect parent
    }
    return err
}

When it happens

Trigger: CreateSysDepartment or UpdateSysDepartment called with a ParentId that is non-zero and not present in the database (e.g. parent deleted concurrently, wrong ID, stale form data).

Common situations: Client submitted a department form where the parent was deleted by another user; API consumer passing parentId of another tenant/dept scope filtered out by data permissions; seeded data referencing deleted IDs.
