I'm trying to use NHibernate for data access, and I have 2 simple entities that look like this:
public class User : IEntity
{
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string Logon { get; set; }
public string Password { get; set; }
public ICollection<Role> Roles { get; set; }
public bool IsNew
{
get { return (ID == 0) ? true : false; }
}
public User()
{
Roles = new List<Role>();
}
}
public class Role : IEntity
{
public int ID { get; set; }
public string RoleName { get; set; }
public string RoleDescription { get; set; }
public bool IsNew
{
get { return (ID == 0) ? true : false; }
}
}
My question......how do I construct a Criteria if I want to find any user that contains a Role with an ID of 1 in it's Roles collection?
Never mind, this ended up being relatively straight forward to do:
// role was the role passed in to my Find method.
var criteria = DetachedCriteria.For(typeof (User))
.CreateCriteria("Roles")
.Add(Restrictions.Eq("ID", role.ID));

I'd like to display the 'ApplicationRole' Name with the 'ApplicationUser' data together using Eager loading.
here is my ApplicationUser
public class ApplicationUser : IdentityUser
{
public string? Name { get; set; }
public string? Department { get; set; }
public bool IsDeleted { get; set; }
public string RoleId { get; set; }
public virtual ApplicationRole Role { get; set; } = new ApplicationRole();
}
public class ApplicationUserDTO
{
public string Id { get; set; }
public int UserId { get; set; }
public string Name { get; set; }
public string UserName { get; set; }
// Foreign Key
public string RoleId { get; set; }
public virtual ApplicationRoleDTO Role { get; set; } = new ApplicationRoleDTO();
}
here is ApplicationRole
[NotMapped]
public class ApplicationRole : IdentityRole
{
public string Id { get; set; }
public string Name { get; set; }
//[InverseProperty(nameof(ApplicationUser.Role))]
public virtual ICollection<ApplicationUser> Users { get; set; } = new List<ApplicationUser>();
}
public class ApplicationRoleDTO
{
public string Id { get; set; }
public string Name { get; set; }
public virtual ICollection<ApplicationUserDTO> Users { get; set; } = new List<ApplicationUserDTO>();
}
and here is the UserRepository
public async Task<IEnumerable<ApplicationUser>> GetAllUsersAsync()
{
//return await _dbContext.User.Where(u => u.IsDeleted == false).ToListAsync();
return await _dbContext.User.Include(u => u.Role).Where(u => u.IsDeleted == false).ToListAsync();
}
public async Task<ApplicationUser> GetUserAsync(string id)
{
return await _dbContext.User.Where(u => u.Id == id).Where(u => u.IsDeleted == false).FirstOrDefaultAsync();
}
But when I use the 'Include' keyword it show this error
When I try to use the string "Role", it also show error
public async Task<IEnumerable<ApplicationUser>> GetAllUsersAsync()
{
return await _dbContext.User.Include("Role").Where(u => u.IsDeleted == false).ToListAsync();
}
Here is the error show
I'm trying to build a simple helpdesk application. In this app, when a ticket is created and displayed, I want to show the first name of the creating user. I am trying to solve how to do this in the best possible way.
I've extended the ApplicationUser class and added FirstName and LastName columns. I also created two foreign keys in my Tickets table, one for the user who created the ticket and one for the agent gets assigned to that ticket. So when the ticket is displayed, I need to show both creators and agents first name + last name's, instead of their UserId's.
This is my ApplicationUser class
public class ApplicationUser : IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }
public ICollection<Ticket> Users { get; set; }
public ICollection<Ticket> Agents { get; set; }
}
This is my model:
public class Ticket
{
public int Id { get; set; }
public string Subject { get; set; }
public string Body { get; set; }
public int Status { get; set; }
public string UserId { get; set; }
public string AgentId { get; set; }
public DateTime Created { get; set; }
public DateTime LastUpdated { get; set; }
public DateTime? Completed { get; set; }
public bool Muted { get; set; }
[ForeignKey("UserId")]
public virtual ApplicationUser TicketUser { get; set; }
[ForeignKey("AgentId")]
public virtual ApplicationUser TicketAgent { get; set; }
}
This is my DbContext:
public DbSet Tickets { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity()
.HasOne(m => m.TicketUser)
.WithMany(t => t.Users)
.HasForeignKey(m => m.UserId)
.OnDelete(DeleteBehavior.Restrict);
modelBuilder.Entity()
.HasOne(m => m.TicketAgent)
.WithMany(t => t.Agents)
.HasForeignKey(m => m.AgentId)
.OnDelete(DeleteBehavior.Restrict);
}
This is the controller action to display a specific ticket:
[HttpGet]
public ViewResult Tickets(int id)
{
TicketDetailsViewModel ticketDetailsViewModel = new TicketDetailsViewModel()
{
Ticket = _ticketRepo.GetTicket(id)
};
return View(ticketDetailsViewModel);
}
This is my viewmodel:
public class TicketDetailsViewModel
{
public Ticket Ticket { get; set; }
}
Now, I can display the full name in my view if I do this:
#inject UserManager userManager;
#{
var ticketUser = (await userManager.FindByIdAsync(Model.Ticket.UserId)).FirstName + " " + (await userManager.FindByIdAsync(Model.Ticket.UserId)).LastName;
}
But I am not sure if this is a good way to do it. I'd like to learn what is the best way to achive this.
Thank you very much.
You can define a _fullname in your ApplicationUser , and then if firstname and lastname both exist, you can directly call Fullname, like:
public class ApplicationUser : IdentityUser
{
private string _fullName; //new property
public string FirstName { get; set; }
public string LastName { get; set; }
[NotMapped]
public string FullName
{
get
{
return _fullName = this.FirstName + "." + this.LastName;
}
set
{
_fullName = value;
}
}
public ICollection<Ticket> Users { get; set; }
public ICollection<Ticket> Agents { get; set; }
}
In view, just call FullName:
#{
var ticketUser = (await userManager.FindByIdAsync(Model.Ticket.UserId)).FullName;
}
In these scenarios I usually prefer to go with an extension method instead of an additional property like proposed by user Jerry Cai, the model remains lighter and cleaner imho:
public static class ApplicationUsersExtensions
{
public static string GetFullname(this ApplicationUser user)
{
return $"{user.FirstName}.{user.LastName}";
}
}
I'v got a backend on Asp.Net Core. Structure of the database looks that:
User - the basics information about user: login, password etc.
Profile - this entity is connected to the"User" one to one relation
Profile photos- each of the users has a own collection of photos.
This entity is connected to the "Profile"
Here is the "User" entity:
public class User
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Username { get; set; }
public byte[] PasswordHash { get; set; }
public byte[] PasswordSalt { get; set; }
public Profile Profile { get; set; }
}
Then Profile:
public class Profile
{
[ForeignKey("User")]
public int Id { get; set; }
public string BannerImageUrl { get; set; }
public string ProfileImageUrl { get; set; }
public string ShortDescription { get; set; }
public string Description { get; set; }
public User User { get; set; }
public ICollection<ProfilePhotos> ProfilePhotos { get; set; }
}
And "ProfilePhotos":
public class ProfilePhotos
{
public int Id { get; set; }
public string ImageUrl { get; set; }
public int ProfileId { get; set; }
public Profile Profile { get; set; }
}
I want to get all profile photos so I created a endpoint to to that:
[HttpGet("{username}/photos")]
public IActionResult GetPhotos(string username)
{
var profilePhotos = _profileService.GetAllPhotos(username);
var model = _mapper.Map<IList<ProfilePhotosModel>>(profilePhotos);
return Ok(model);
}
To get all photos I use a method from "profileService":
public IEnumerable<ProfilePhotos> GetAllPhotos(string username)
{
return _context.ProfilePhotos.Include(a=>a.Profile).ThenInclude(b=>b.User).Where(x => x.Profile.User.Username == username);
}
On response I want to get a id of photo, photoUrl and username so I mapped my profile photos to "ProfilePhotosModel"
public class ProfilePhotosModel
{
public int Id { get; set; }
public string ImageUrl { get; set; }
public string Username { get; set; }
}
but unfortunately on response I only get Id and photoUrl. The username is null :(
What am I doing wrong?
You could add custom mapping for the Username property.
var config = new MapperConfiguration(cfg =>
{
cfg.CreateMap<ProfilePhotos, ProfilePhotosModel>()
.ForMember(m => m.Username, exp => exp.MapFrom(p => p.Profile.User.Username));
});
I'm using EFCore (With Cosmos), and for some reason it's adding a 2nd key for me, on the convention of id, despite having a property name Id, with the KeyAttribute.
Anyway I can stop this?
public class User
{
public User()
{
}
public User(ClaimsPrincipal principal)
{
Id = principal.FindFirst(ClaimTypes.NameIdentifier).Value;
FirstName = principal.FindFirst(ClaimTypes.GivenName).Value;
Surname = principal.FindFirst(ClaimTypes.Surname).Value;
Email = principal.FindFirst(ClaimTypes.Email).Value;
}
[Key]
public string Id { get; set; }
public string FirstName { get; set; }
public string Surname { get; set; }
public string Email { get; set; }
public string Password { get; set; }
public bool Active { get; set; }
public DateTime CreatedDate { get; set; }
public DateTime LastLoginTime { get; set; }
public Company Company { get; set; }
public User CreatedBy { get; set; }
//Hack to get around EF/Cosmos Enum error
private string UserType { get; set;}
[NotMapped]
public UserType UserTypeEnum
{
get
{
if (string.IsNullOrWhiteSpace(UserType))
{
return Models.UserType.User;
}
return (UserType)Enum.Parse(typeof(UserType), UserType);
}
set
{
UserType = value.ToString();
}
}
}
You can add [Newtonsoft.Json.JsonProperty(PropertyName="id")] above your Id property

Hello I have problem in one query. Why it's always return no value.
public List<UserDetail> userSearchModel(UserSearchModel searchModel)
{
string userid = User.Identity.GetUserId();
var user = _dbContext.UserDetails.Where(x => x.Id == userid);
var result = _dbContext.UserDetails.Except(user).ToList().AsQueryable();
if (searchModel != null)
{
if (searchModel.LanguageId.Count() != 0)
{
List<UserDetailLanguage> usrDetails = new List<UserDetailLanguage>();
foreach (var item in searchModel.LanguageId)
{
var details = _dbContext.UserDetailLanguages.Where(x => x.LanguageId == item).ToList();
foreach (var item2 in details)
{
usrDetails.Add(item2);
}
}
result = result.Where(x => x.UserDetailLanguages == usrDetails);
}
}
return result.ToList();
}
I want to get results which are the same in usrDetails list and in result.UserDetailLanguages.
In result.UserDetailLanguages I have record equals to record in usrDetails but this not want retrieve.
Here is my model:
public class UserDetail
{
public UserDetail()
{
this.UserDetailLanguages = new HashSet<UserDetailLanguage>();
}
[Key, ForeignKey("User")]
public string Id { get; set; }
public DateTime Birthday { get; set; }
public string Sex { get; set; }
public string Country { get; set; }
public string About { get; set; }
[NotMapped]
public int Age { get { return DateTime.Now.Year - Birthday.Year; } }
public virtual ApplicationUser User { get; set; }
public virtual ICollection<UserDetailLanguage> UserDetailLanguages { get; set; }
}
public class UserDetailLanguage
{
public Int32 Id { get; set; }
public virtual UserDetail UserDetail { get; set; }
public string UserDetailId { get; set; }
public virtual Language Language { get; set; }
public Int32 LanguageId { get; set; }
public Boolean IsKnown { get; set; }
public static implicit operator List<object>(UserDetailLanguage v)
{
throw new NotImplementedException();
}
}
public class Language
{
public Language()
{
this.UserDetailLanguages = new HashSet<UserDetailLanguage>();
}
public int Id { get; set; }
public string Value { get; set; }
public string Name { get; set; }
public virtual ICollection<UserDetailLanguage> UserDetailLanguages { get; set; }
}
What I'm doing wrong?
If you want to see if your value is in a list you use the Contains function of the list -- like this:
result = result.Where(x => usrDetails.Contains(x.UserDetailLanguage));
If you want to see if there are any items in both lists you can use intersection like this:
result = result.Where(x => usrDetails.Intersect(x.UserDetailLanguage).Count() > 0);
Looks like you are checking equality between lists in following code
result = result.Where(x => x.UserDetailLanguages == usrDetails);
This might not work, to check equality for lists you can use something like
Enumerable.SequenceEqual(FirstList.OrderBy(fList => fList),
SecondList.OrderBy(sList => sList))
