Error message

该部门下存在用户,不允许删除

What it means

DeleteSysDepartment refuses to delete a department that still has users whose primary dept_id points at it. After the child-department check, it counts sys_user rows with dept_id = id and blocks deletion when userCount > 0.

Solutions

1. Reassign those users to another department (update their dept_id, e.g. via user edit or SetDepartmentUsers) before deleting
2. Use the department member management page to move users out first
3. Delete or reassign the users if they are no longer needed

var userCount int64
global.GVA_DB.Model(&system.SysUser{}).Where("dept_id = ?", id).Count(&userCount)
if userCount > 0 {
    return fmt.Errorf("%d users still assigned to this department", userCount)
}

if err := deptService.DeleteSysDepartment(ctx, id); err != nil {
    if err.Error() == "该部门下存在用户,不允许删除" {
        // route users to the member-reassignment flow
    }
    return err
}

When it happens

Trigger: Deleting a department where one or more sys_user rows have dept_id equal to that department ID.

Common situations: Users were assigned to the department as their main department; bulk user import set dept_id; admin tries to remove an active team department.
