I'm new to Net Core and studying it at the moment. I am creating a web based app for users to create events and register for these events and and need help.
I have an EventsCoordinator and Member Model which inherit from my User model which inherits from ApplicationUser : IdenityUser. In my Account Register.cshtml, I can create new users and they are added to the database in my User table, however I'd like when they select the AccountType (enum value (EventCoordinator, Member) that they will then be added to the applicable table e.g. EventsCoordinator or Member, however I am having trouble doing this. I added an IF statement but not sure what to add then...
I've yet to add roles as I want to create different levels of authorization based on these account types but that will have to try work on that later.
Any help for this newbie, would be great!
Thanks!
public async Task<IActionResult> OnPostAsync(string returnUrl = null)
{
returnUrl ??= Url.Content("~/");
ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
if (ModelState.IsValid)
{
var user = new User { UserName = Input.Email, Email = Input.Email, FirstName = Input.FirstName, LastName = Input.LastName, DOB = Input.DOB, Address = Input.Address, AccountType = (Models.AccountType)Input.AccountType };
if (AccountType == AccountType.EventCoordinator)

}

}

if (result.Succeeded)
{

var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);

}
// If we got this far, something failed, redisplay form
return Page();
}
In your if statement add the the user to the table or assign the user its role (EventCoordinator ir Member).
If EventCoordinator & Member are Roles you add the user with the UserManager.
Like
await userManager.AddToRoleAsync(user,"EventCoordinator ");
If those 2 are not roles and are columns in a table in your DB
You add the users id to the specific column in your DB.
If possible specify where or how do you save the AccountType or want to save it
I am new in asp.net mvc. I am trying to build role wise dynamic menu show in the view page. Each user can have multiple role.
I have a join query like:
My Controller looks like with join query:
var query= (from rMPageMap in db.RoleModulePageMaps
join userRole in db.UserRoleMaps
on rMPageMap.RoleId equals
join roleMaster in db.RoleMasters
on rMPageMap.RoleId equals roleMaster.Id
join modMaster in db.ModuleMaster
on rMPageMap.ModuleId equals modMaster.Id
join sModMaster in db.SubModuleMasters
on rMPageMap.SubModuleId equals sModMaster.Id
join pMaster in db.PageMasters
on rMPageMap.PageId equals pMaster.Id
where (userRole.UserId == appuser.Id &)
select new
{
rMPageMap.RoleId,
rMPageMap.PageMaster.Name,
roleMaster.Id,
roleName = roleMaster.Name,
modId = modMaster.Id,
moduleName = modMaster.Name,
subModuleId = sModMaster.Id,
subModuleName = sModMaster.Name,
pageId = pMaster.Id,
pageName = pMaster.Name,
parentPageId = pMaster.ParentPageId,
rMPageMap.AddData,
rMPageMap.EditData,
rMPageMap.ViewData,
rMPageMap.DeleteData,
rMPageMap.ShowInDashBoard,
rMPageMap.ShowInMenu
});
Session["rolemodulepage"] = query;
I find the values in the session while debugging. but i can not retrieve data from this using foreach loop in layout page.
Here is my view page that i try ro retrieve but does not work.
View Page:
#if (Request.IsAuthenticated)
{
var sessionVar = System.Web.HttpContext.Current.Session["rolemodulepage"];
foreach(var i in sessionVar) // error
{
#i.... // error
}
// So here how to retrieve data from session using foreach loop. I tried but does not work. Pls help. If you have some resource for dynamically mane show in view page pls share with me.
Can anyone explain that how to do it using showing dynamic menu by role based user in master layout page. Wihout login none can enter the site, pls explain with examples so that i can understand. Thanks in advance.
You query is generating a collection of anonymous objects which you cannot access in the view. Create a view model containing the properties you need and project your query into it, for example
public class MenuVM
{
public int RoleId { get; set; }
public string PageMasterName { get; set; }
....
}
and then modify the query to
var query = (from rMPageMap in db.RoleModulePageMaps
....
where (userRole.UserId == appuser.Id &)
select(new MenuVM()
{
RoleId = rMPageMap.RoleId,
PageMasterName = rMPageMap.PageMaster.Name,
....
}).AsEnumerable()
;
and then in the view you can cast the Session value and loop through it
var sessionVar = HttpContext.Current.Session["rolemodulepage"] as IEnumerable<MenuVM>;
if (sessionVar null)
{
foreach(var i in sessionVar)
{
....
However, as this is for generating a menu in a layout, I suggest you create move the code to a child action only method that returns a strongly typed partial view, for example in say CommonController
[ChildActionOnly]
public PartialViewResult Menu()
{
if (!Request.IsAuthenticated)
{
return null;
}
// Check if the session variable exists and if not, generate the query
// and add the result to session
return PartialView("_Menu", query);
}
and the _Menu.cshtml view would be
#model IEnumerable<MenuVM>
#foreach (var i in Model)
{
....
}
and in the layout, use
#{ Html.RenderAction("Menu", "Common"); }
to generate the html for the menu.
Grettings. I see a thousand of questions and i lost on every one of them... So... Basically i start a new project on VS (WebAPI) with Authentication. I put the token on the header and the methods with
[Authorize]
works fine. Later i add a two roles into the table dbo.AspNetRoles (admin and users) and to one user i add the relationship in the table dbo.AspNetUserRoles like this:
USER ID | Roleid
-----------------------
1d156e98-fc8b-4dcb-8dba-f7c66131f488 | 1001
So, when i try to put this:
[Authorize(role="admin")]
Dont work... The request is denied.
What i need to do exactly?
Thanks
It's not "Authentication" but "Authorize". Try this:
[Authorize(Roles = "admin")]
But first you've to create your roles:
context.Roles.Add(new IdentityRole { Name = "admin" });
context.SaveChanges();
And assign role to the user:
var role = context.Roles.SingleOrDefault(m => m.Name == "admin");
user.Roles.Add(new IdentityUserRole { RoleId = role.Id });
Database initialization code can be put anywhere you want, it depends on you:
when the application starts - check if roles are there, if no then create them
generate migration and update the migration script by custom role inserts
put them manually in the database - BUT YOU HAVE TO DO IN PROPER WAY - add roles from the code and check what has been changed in the database
So at the end i use this following code to resolve this:
public class DAO
{
public static void addRoleToUser(ApplicationUser user, string role)
{
// EL SIGUIENTE CODIGO AGREGA AL USUARIO UN ROL
ApplicationDbContext context = new ApplicationDbContext();
var userStore = new UserStore<ApplicationUser>(context);
var userManager = new UserManager<ApplicationUser>(userStore);
userManager.AddToRole(user.Id,role);
}
}
This sync the role to the user and the context db.
In the controller after register a new user automatically adds the rol "User" with the code:
// POST api/Account/Register
[AllowAnonymous]
[Route("Register")]
public async Task<IHttpActionResult> Register(RegisterBindingModel model)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
var user = new ApplicationUser() { UserName = model.Email, Email = model.Email };
IdentityResult result = await UserManager.CreateAsync(user, model.Password);
if (!result.Succeeded)
{
return GetErrorResult(result);
}
// Codigo de Ali para agregar el rol "User" al usuario inmediatamente es creado
DAO.addRoleToUser(user, "User");
return Ok();
}
Thanks to dawidr to help me to go deep on this.
I am new guy in ASP.NET MVC 4. I want to populate dropdownlist from database table BO where Column name is Id, Code, Name, OrgId. I want to bind two Code & Namecolumn's data to DataTextfield and Id column Data to DataValueField of dropdown. I have created code for this which are as follows BUT ITS NOT RETURNING DATA FROM TABLE and var BOList is remain empty :
my connectionstring is
<add name="iRegDBContext"
connectionString="Data Source=****;Initial Catalog=iReg;User ID=**;Password=****;Integrated Security=True"
providerName="System.Data.SqlClient"
/>
My Controller class :
public class iRegController : Controller
{
private iRegDBContext l_oDbBO = new iRegDBContext();
// GET: /iReg/
public ActionResult PopulatejQgrid()
{
var BOList = l_oDbBO
.BO
.ToList()
.Select(d => new SelectListItem
{
Value = d.Id.ToString(),
Text = d.Name + "[ " + d.Code + " ]"
});
ViewBag.BOData = new SelectList(BOList, "Value", "Text");
return View();
}
}
My Model class :
public class BO
{
public Guid Id { get; set; }
public string Code { get; set; }
public string Name { get; set; }
}
public class iRegDBContext : DbContext
{
public DbSet<BO> BO { get; set; }
}
My cshtml class :
#model MvciReg.Models.BO
#{
ViewBag.Title = "PopulatejQgrid";
}
#using (Html.BeginForm())
{
<fieldset>
BO :
#Html.DropDownList("BOData")
<p>
<input type="submit" value="Go" />
</p>
</fieldset>
}
I really don't know where I am going wrong. I developed my code from reference of following link Click here . Kindly suggest correction in code ...
UPDATE: I tried following Matt Bodily's code in my controller and what I see is code is not fetching data from database and that code is
public ActionResult populatejQgrid()
{
ViewBag.BOData = GetDropDown();
return View();
}
public static List<SelectListItem> GetDropDown()
{
List<SelectListItem> ls = new List<SelectListItem>();
var lm = from m in db.BOs //fetch data from database
select m;
foreach (var temp in lm)
{
ls.Add(new SelectListItem() { Text = temp.Name, Value = temp.Id.ToString() });
}
return ls;
}
In Controller :
#Html.DropDownList("BOData", (List<SelectListItem>)ViewBag.BOData)
But when I saw value of ls through watch it always show me Count = 0 but its not giving me any error.
I found something new this problem. When I kept mouse pointer over var lm; it shows me query and in query table name in FROM clause is not that one in my SQL database. My SQL table name is BO and in query it is taking BOes. I don't know from where this name is coming. I think this is the main cause of all this problem So How I overcome this??
First Create a BO list for Dropdownlist in VIEW
#{
var Bolst= Model.BO.Select(cl => new SelectListItem
{
Value = cl.Value.ToString(),
Text = cl.Text== null ? String.Empty : cl.Text
});
}
#(Html.DropDownList("sampleDropdown", BOlst, "-----Select-----"))
In Controller:
return View(BOlst); // why use Viewbag when directly pass it to view
from what I see in your code you are creating the select list and setting the ViewBag.BOData on the controller.
So in order to render it on the view you should do this
#Html.DropDownList(ViewBag.BOData)
instead of
#Html.DropDownList("BOData")
Regarding the access to the database are you trying to use "code first" in an existing database?
If you are you need to override the context constructor like this
public class iRegDBContext : DbContext
{
public iRegDBContext()
:base("Name= iRegDBContext")
{
}
}
see this link http://msdn.microsoft.com/en-us/data/jj200620.aspx
Hope it helps.
try building your dropdown this way
#Html.DropDownList(x => x.Selected, PathToController.GetDropDown())
and then in your controller
public static List<SelectListItem> GetDropDown()
{
List<SelectListItem> ls = new List<SelectListItem>();
lm = (call database);
foreach (var temp in lm)
{
ls.Add(new SelectListItem() { Text = temp.name, Value = temp.id });
}
return ls;
}
Hopefully this helps
I recently had this issue also and managed to get it working using Viewbag. You will need to make it fit your Db tables but it works and is quite simple.
Populating Drop Down Box with Db Data
I've been reading over several of the questions similar to this, dealing with customizing the #Html.ValidationMessageFor but none of them touched on what I'm looking to do.
The current form I'm working on is editing a user in a database. Within this form I need to check that the email being entered is not already used for another user. I have the logic, but what I don't have is the custom validation message to appear on the page if they use an already in-use email.
Controller code:
[HttpPost]
public ActionResult EditUser(int id, EditUserModel model)
{
if (ModelState.IsValid)
{
tbl_Users editedUser = tblUsers.EditUser(id, model, HttpContext.User.Identity.Name);
tblHSDA.EditHSDAS(id, editedUser, model.hsdas, HttpContext.User.Identity.Name);
return Redirect("~/UserManage/ListActiveUsers");
}
if (tblUsers.ValidateEmailInUse(model.Email))
{
// change validation message and return View(model);
}
tbl_Users tbl_users = db.tbl_Users.SingleOrDefault(item => item.User_id == id);
ViewBag.hsdas = tblHSDA.GetHSDANameAlpha();
ViewBag.Username = tbl_users.Username;
return View(model);
}
Is this something done at the Controller level?
as per your logic the email check part will never execute if the user fills in the form correctly and provides a duplicate email
what you can do is change the ActionResult like
[HttpPost]
public ActionResult EditUser(int id, EditUserModel model)
{
if (ModelState.IsValid)
{
if(!CheckEmail(model.Email)){
tbl_Users editedUser = tblUsers.EditUser(id, model, HttpContext.User.Identity.Name);
tblHSDA.EditHSDAS(id, editedUser, model.hsdas, HttpContext.User.Identity.Name);
return Redirect("~/UserManage/ListActiveUsers");
}else{
ModelState.AddModelError("Email","Email provided is already in use...")
}
}
tbl_Users tbl_users = db.tbl_Users.SingleOrDefault(item => item.User_id == id);
ViewBag.hsdas = tblHSDA.GetHSDANameAlpha();
ViewBag.Username = tbl_users.Username;
return View(model);
}
private bool CheckEmail(string email){
//email check logic
// return true or false
}
