Public Language CurrentLang

{

Get

{

return CurrentUser! = null? CurrentUser.Language: null;

}

}

protected override void Initialize(RequestContext requestContext)

{

CultureInfo ci = new CultureInfo(" ru");

Thread.CurrentThread.CurrentCulture = ci;

base.Initialize(requestContext);

}

}

И /Areas/Admin/Controller/HomeController.cs:

[Authorize(Roles=" admin")]

public class HomeController: AdminController

{

public ActionResult Index()

{

return View();

}

public ActionResult AdminMenu()

{

return View();

}

public ActionResult LangMenu()

{

if (CurrentLang == null)

{

var lang = repository.Languages.FirstOrDefault();

repository.ChangeLanguage(currentUser, lang.Code);

}

var langProxy = new LangAdminView(repository, CurrentLang.Code);

return View(langProxy);

}

[HttpPost]

public ActionResult ChangeLanguage(string SelectedLang)

{

repository.ChangeLanguage(currentUser, SelectedLang);

return Redirect(" ~/admin");

}

}

Итак, AdminController выбирает и устанавливает, в каком языке мы сейчас работаем. Если данный язык не установлен, то выбирается первый попавшийся, и в HomeController.cs: LangMenu устанавливается для пользователя. Создадим LangAdminView.cs (/Models/ViewModel/LangAdminView.cs):

public class LangAdminView

{

private IRepository Repository

{

get

{

return DependencyResolver.Current.GetService< IRepository> ();

}

}

public string SelectedLang {get; set; }

public List< SelectListItem> Langs { get; set; }

public LangAdminView(string currentLang)

{

currentLang = currentLang?? " ";

Langs = new List< SelectListItem> ();

foreach (var lang in Repository.Languages)

{

Langs.Add(new SelectListItem()

{

Selected = (string.Compare(currentLang, lang.Code, true) == 0),

Value = lang.Code,

Text = lang.Name

});

}

}

}

Опишем все View (+js-файлы):

/Areas/Admin/Views/Shared/_Layout.cshtml:

@{

var currentUser = ((LessonProject.Controllers.BaseController)ViewContext.Controller).CurrentUser;

}

@RenderSection(" scripts", required: false)

< /body>

< /html>

Index.cshtml (/Areas/Admin/Views/Home/Index.cshtml):

@{

ViewBag.Title = " Index";

Layout = " ~/Areas/Admin/Views/Shared/_Layout.cshtml";

}

< h2> Админка< /h2>

AdminMenu.cshtml (/Areas/Admin/Views/Home/AdminMenu.cshtml):

< li>

@Html.ActionLink(" Главная", " Index", " Home")

< /li>

< li>

@Html.ActionLink(" Посты", " Index", " Post")

LangMenu.cshtml (/Areas/Admin/Views/Home/LangMenu.cshtml):

< li>

@using (Html.BeginForm(" ChangeLanguage", " Home", FormMethod.Post, new { id = " SelectLangForm" }))

{

@Html.DropDownList(" SelectedLang", Model.Langs)

}

< /li>

И обработчик SelectedLang (/Scripts/admin/common.js):

function AdminCommon()

{

_this = this;

this.init = function ()

{

$(" #SelectedLang").change(function () {

$(" #SelectLangForm").submit();

});

}

}

var adminCommon = null;

$().ready(function () {

adminCommon = new AdminCommon();

adminCommon.init();

});

Заходим под админом (у меня это chernikov@gmail.com) и переходим на страницу https://localhost/admin:

Если не удалось зайти и выкинуло на /Login, то проверьте связь UserRole в БД, чтобы текущий пользователь имел роль с кодом “admin”.

Открываем выпадающий список языков. Он и показывает, в каком языке мы в данный момент работаем.

Добавляем контроллер PostController.cs (/Areas/Admin/Controllers/PostController.cs):

public class PostController: AdminController

{

public ActionResult Index(int page = 1)

{

var list = Repository.Posts.OrderByDescending(p => p.AddedDate);

var data = new PageableData< Post> (list, page);

data.List.ForEach(p => p.CurrentLang = CurrentLang.ID);

return View(data);

}

[HttpGet]

public ActionResult Create()

{

var postView = new PostView

{

CurrentLang = CurrentLang.ID

};

return View(" Edit", postView);

}

[HttpGet]

public ActionResult Edit(int id)

{

var post = Repository.Posts.FirstOrDefault(p => p.ID == id);

if (post! = null)

{

post.CurrentLang = CurrentLang.ID;

var postView = (PostView)ModelMapper.Map(post, typeof(Post), typeof(PostView));

return View(postView);

}

return RedirectToNotFoundPage;

}

[HttpPost]

[ValidateInput(false)]

public ActionResult Edit(PostView postView)

{

if (ModelState.IsValid)

{

var post = (Post)ModelMapper.Map(postView, typeof(PostView), typeof(Post));

post.CurrentLang = CurrentLang.ID;

if (post.ID == 0)

{

post.UserID = CurrentUser.ID;

Repository.CreatePost(post);

}

else

{

Repository.UpdatePost(post);

}

TempData[" Message" ] = " Сохранено! ";

return RedirectToAction(" Index");

}

return View(postView);

}

public ActionResult Delete(int id)

{

Repository.RemovePost(id);

TempData[" Message" ] = " Удален пост";

return RedirectToAction(" Index");

}

}

Изменим PageableData, чтобы можно было сделать Foreach (/Models/Info/PageableData.cs):

public class PageableData< T> where T: class

{

protected static int ItemPerPageDefault = 20;

public List< T> List { get; set; }

…

public PageableData(IQueryable< T> queryableSet, int page, int itemPerPage = 0)

{

…

List = queryableSet.Skip((PageNo - 1) * itemPerPage).Take(itemPerPage) .ToList();

}

}

Index.cshtml (/Areas/Admin/Views/Post/Index.cshtml):

@model LessonProject.Models.Info.PageableData< LessonProject.Model.Post>

@{

ViewBag.Title = " Посты";

Layout = " ~/Areas/Admin/Views/Shared/_Layout.cshtml";

}

< h2>

Посты

< /h2>

@Html.ActionLink(" Добавить", " Create", " Post", null, new { @class = " btn" })
