ASP.NET MVC5+EF6+EasyUI 后台管理系统（27）-权限管理系统-分配用户给角色

系列目录

分配用户给角色，跟分配角色给用户操作是基本一致的。

打开模块维护，展开SysRole模块添加一个操作码，并赋予权限

设置好之后将权限授权给管理员，在SysRole的index添加操作码与js事件

@Html.ToolButton("btnAllot", "icon-share", "分配用户", perm, "Allot", true)

$("#btnAllot").click(function () {
            var row = $('#List').datagrid('getSelected');
            if (row != null) {
                $("#modalwindow").html("<iframe width='100%' height='100%' scrolling='no' frameborder='0' src='/SysRole/GetUserByRole?roleId=" + row.Id + "&Ieguid=" + GetGuid() + "'></iframe>");
                $("#modalwindow").window({ title: '分配用户', width: , height: , iconCls: 'icon-edit' }).window('open');
            } else { $.messageBox5s('提示', '请选择一个需要分配用户的角色'); }
        });

由于和26讲基本一致，只是User改成Role,Role改成User
在SysRoleController添加以下3个方法

 #region 设置角色用户
        [SupportFilter(ActionName = "Allot")]
        public ActionResult GetUserByRole(string roleId)
        {
            ViewBag.RoleId = roleId;
            ViewBag.Perm = GetPermission();
            return View();
        }

        [SupportFilter(ActionName="Allot")]
        public JsonResult GetUserListByRole(GridPager pager,string roleId)
        {
            if (string.IsNullOrWhiteSpace(roleId))
                return Json();
            var userList = m_BLL.GetUserByRoleId(ref pager, roleId);

            var jsonData = new
            {
                total = pager.totalRows,
                rows = (
                    from r in userList
                    select new SysUserModel()
                    {
                        Id = r.Id,
                        UserName = r.UserName,
                        TrueName = r.TrueName,
                        Flag = r.flag == "" ? "" : "",
                    }
                ).ToArray()
            };
            return Json(jsonData);
        }
        #endregion

        [SupportFilter(ActionName = "Save")]
        public JsonResult UpdateUserRoleByRoleId(string roleId,string userIds)
        {
            string[] arr = userIds.Split(',');

            if (m_BLL.UpdateSysRoleSysUser(roleId,arr))
            {
                LogHandler.WriteServiceLog(GetUserId(), "Ids:" + arr, "成功", "分配用户", "角色设置");
                return Json(JsonHandler.CreateMessage(, Suggestion.SetSucceed), JsonRequestBehavior.AllowGet);
            }
            else
            {
                string ErrorCol = errors.Error;
                LogHandler.WriteServiceLog(GetUserId(), "Ids:" + arr, "失败", "分配用户", "角色设置");
                return Json(JsonHandler.CreateMessage(, Suggestion.SetFail), JsonRequestBehavior.AllowGet);
            }

        }

GetUserByRole为弹出视图

GetUserListByRole为根据选择的用户获取角色并让已经分配的角色呈现选择状态 （存储过程实现）

Create proc [dbo].[P_Sys_GetUserByRoleId]
@RoleId varchar()
as
begin
--读取角色所包含的用户
select a.*,ISNULL(b.SysUserId,) as flag from SysUser a left join
SysRoleSysUser b on a.Id=b.SysUserId
and b.SysRoleId=@RoleId
order by b.SysRoleId desc
end 

P_Sys_GetUserByRoleId

UpdateUserRoleByRoleId更新选择的后的情况（存储过程实现）

Create PROCEDURE [dbo].[P_Sys_UpdateSysRoleSysUser]
@roleId varchar(),@userId varchar()
AS
--更新角色用户中间关系表
BEGIN
    insert into SysRoleSysUser(SysRoleId,SysUserId)
        values(@roleId,@userId)
END

P_Sys_UpdateSysRoleSysUser

添加BLL方法

/// <summary>
        /// 获取角色对应的所有用户
        /// </summary>
        /// <param name="roleId">角色id</param>
        /// <returns></returns>
        public string GetRefSysUser(string roleId)
        {
            string UserName = "";
            var userList = m_Rep.GetRefSysUser(db, roleId);
            if (userList != null)
            {
                foreach (var user in userList)
                {
                    UserName += "[" + user.UserName + "] ";
                }
            }
            return UserName;
        }

        public IQueryable<P_Sys_GetUserByRoleId_Result> GetUserByRoleId(ref GridPager pager, string roleId)
        {
            IQueryable<P_Sys_GetUserByRoleId_Result> queryData = m_Rep.GetUserByRoleId(db, roleId);
            pager.totalRows = queryData.Count();
            queryData = m_Rep.GetUserByRoleId(db, roleId);
            return queryData.Skip((pager.page - ) * pager.rows).Take(pager.rows);
        }
        public bool UpdateSysRoleSysUser(string roleId, string[] userIds)
        {
            try
            {
                m_Rep.UpdateSysRoleSysUser(roleId, userIds);
                return true;
            }
            catch (Exception ex)
            {
                ExceptionHander.WriteException(ex);
                return false;
            }
        }

BLL

添加DAL方法

 public IQueryable<SysUser> GetRefSysUser(DBContainer db, string id)
        {
            if (!string.IsNullOrEmpty(id))
            {
                return from m in db.SysRole
                       from f in m.SysUser
                       where m.Id == id
                       select f;
            }
            return null;
        }

        public IQueryable<P_Sys_GetUserByRoleId_Result> GetUserByRoleId(DBContainer db, string roleId)
        {
            return db.P_Sys_GetUserByRoleId(roleId).AsQueryable();
        }

        public void UpdateSysRoleSysUser(string roleId,string[] userIds)
        {
            using(DBContainer db = new DBContainer())
            {
                db.P_Sys_DeleteSysRoleSysUserByRoleId(roleId);
                foreach (string userid in userIds)
                {
                    if (!string.IsNullOrWhiteSpace(userid))
                    {
                        db.P_Sys_UpdateSysRoleSysUser(roleId, userid);
                    }
                }
                db.SaveChanges();
            }
        }

DAL

新角色用户中间关系表,前删除关联

Create PROCEDURE [dbo].[P_Sys_DeleteSysRoleSysUserByRoleId]
@roleId varchar()
AS
--更新角色用户中间关系表,前删除关联
BEGIN
    delete SysRoleSysUser where SysRoleId=@roleId
END

P_Sys_DeleteSysRoleSysUserByRoleId

自行添加BLL和DAL的接口方法
添加GetUserByRole.cshtml视图

GetUserByRole

理论上效果都会出来。
