I'm running into this compile error when using ThenInclude on a entity. The error is listed below. I can't see anything wrong with the relationships between the two entities. What gives, I'm banging my head against a wall here!
'ICollection<OptionType>' does not contain a definition for 'ProductOption'
and no extension method 'ProductOption' accepting a first argument of type
'ICollection<OptionType>' could be found (are you missing a using directive or
an assembly reference?)
Here are the two entities in question and related code
public async Task<ProductEditor> Edit(Expression<Func<Product, bool>> filter)
{
var product = _repo.Find(filter)

I want to map MinerStatus from Entity.Miner.
I tried to include Miner entity in Issue entity, but it did not happen.

Mapping profiles
I need to do it with AutoMapper, but it returns null.
This is my code:
Issue entity:

How can I use a primary key as a foreign key of another table's in two columns.
public class ResumeSharing
{
[Key]
public int ResumeSharingId { get; set; }
[ForeignKey("AppliedJobs")]
public int AppliedJobId { get; set; }
public virtual AppliedJob AppliedJobs { get; set; }
public bool OwnCompany { get; set; }
[Display(Name = "RecruiterFrom")]
public int RecruiterId { get; set; }
public virtual Recruiter Recruiters { get; set; }
[Display(Name = "RecruiterTo")]
public int RecruiterId { get; set; }
public virtual Recruiter Recruiters { get; set; }
[ForeignKey("Companies")]
public int CompanyId { get; set; }
public virtual Company Companies { get; set; }
public string SharedFiles { get; set; }
}
I want to call RecruiterId twice in this table. How can I do this?
you have to add navigation properties
public class ResumeSharing
{
[Key]
public int ResumeSharingId { get; set; }
[ForeignKey("AppliedJob")]
public int AppliedJobId { get; set; }
public virtual AppliedJob AppliedJob { get; set; }
public bool OwnCompany { get; set; }
[Display(Name = "RecruiterFrom")]
public int RecruiterFromId { get; set; }
[ForeignKey(nameof(RecruiterFromId))]
[InverseProperty("RecruiterFroms")]
public virtual Recruiter RecruiterFrom { get; set; }
[Display(Name = "RecruiterTo")]
public int RecruiterToId { get; set; }
[ForeignKey(nameof(RecruiterToId))]
[InverseProperty("RecruiterTos")]
public virtual Recruiter RecruiterTo { get; set; }
[ForeignKey("Company")]
public int CompanyId { get; set; }
public virtual Company Company { get; set; }
public string SharedFiles { get; set; }
}
public class Recruiter
{
[Key]
public int Id { get; set; }
[InverseProperty(nameof(ResumeSharing.RecruiterFrom))]
public virtual ICollection<Recruiter> RecruiterFroms { get; set; }
[InverseProperty(nameof(ResumeSharing.RecruiterTo))]
public virtual ICollection<Recruiter> RecruiterTos { get; set; }

There is ICollection<InformationСontent> InformationСontents in Area class. Schema: Area -> Floor -> Place
I'd like to get all InformationContent from all Area in all Floor in all Place. How to do it?
I have only 1 linq query that returns all InformationContent in Area by id:
public async Task<IEnumerable<InformationСontent>> GetAreaInformationContentToList(int areaId)
{
// version 1
var sales = await _unitOfWork.Context.Areas.Include(x => x.Floor)
.ThenInclude(x => x.Place)
.Where(x => x.Id == areaId)
.SelectMany(x => x.InformationСontents)
.Where(x => x.ActiveTo > DateTime.Now)
.ToListAsync();
return sales;
//version 2
//var sales = await _unitOfWork.Context.Areas.FromSqlRaw("").ToListAsync();
}

I have 2 models:
public partial class Movie
{
public Movie()
{
TimeTables = new HashSet<TimeTable>();
}
[Key]
public int MovieId { get; set; }
public string MovieName { get; set; }
public int MovieGenre { get; set; }
public string MoviePicture { get; set; }
public string MovieDescription { get; set; }
public string MovieShortText { get; set; }
public bool? MovieIs3d { get; set; }
public bool? MovieIsImax { get; set; }
public int MovieLanguage { get; set; }
public bool? MovieSubtitled { get; set; }
public int? MovieMinimalAge { get; set; }
public bool? MovieHasDrugs { get; set; }
public bool? MovieHasViolence { get; set; }
public bool? MovieHasSex { get; set; }
public bool? MovieHasSwearing { get; set; }
public bool? MovieIsScary { get; set; }
public bool? MovieHasDiscrimination { get; set; }
public string MovieTrailer { get; set; }
public int MovieLength { get; set; }
public int? Genre_GenreId { get; set; }
public int? Language_LanguageId { get; set; }
public virtual Genre Genre { get; set; }
public virtual Language Language { get; set; }
public virtual ICollection<TimeTable> TimeTables { get; set; }
}
And:
public partial class TimeTable
{
public TimeTable()
{
Reservations = new HashSet<Reservation>();
}
public int TimeTableId { get; set; }
public int MovieId { get; set; }
public int RoomId { get; set; }
public int SeatsAvaible { get; set; }
public DateTime StartTime { get; set; }
public DateTime EndTime { get; set; }
public virtual Movie Movie { get; set; }
public virtual ICollection<Reservation> Reservations { get; set; }
public virtual Room Room { get; set; }
}
I want to show all the records from Movie which have one or more records in TimeTable and where StartDate.date == [given datetime].
With a simple query the movies are showing multiple times. I have tried a distinct() but that changes nothing.
Anybody here who have the solution?
Current query:
var times2 =
(from s in timetablerepo.TimeTables
orderby s.StartTime.TimeOfDay
where s.StartTime.Date == datetime.Date
select s).Distinct().ToList();
Why not start with movies first and filter by timetable:
var times = timetablerepo.Movies
.Where(m => m.TimeTables.Any(t => t.StartDate.Date == <yourdate>));
Table 1: Articles
Table 2: ArticleCategories
how do I represent the relationship between the two tables which is a 1->1 relationship:
I can do the following, but I'm not sure it's the correct way :
public class Article
{
public int ArticleIndex { get; set; }
public int Category { get; set; }
public Guid User { get; set; }
public int Parent { get; set; }
public int Level { get; set; }
public int Order { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateExpires { get; set; }
public bool Show { get; set; }
public string Title { get; set; }
public string TitleHtml { get; set; }
public string Content { get; set; }
public string ContentHtml { get; set; }
public string ShortTitle { get; set; }
public ArticleCategory Category { get; set; }
}
public class ArticleCategory
{
public int CategoryIndex { get; set; }
public string Name { get; set; }
}
By convention, Code First expects an Id property for each class/table. Then you can do something like this:
public class Article
{
public int Id { get; set; }
public int ArticleIndex { get; set; }
public int Category { get; set; }
public Guid User { get; set; }
public int Parent { get; set; }
public int Level { get; set; }
public int Order { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateExpires { get; set; }
public bool Show { get; set; }
public string Title { get; set; }
public string TitleHtml { get; set; }
public string Content { get; set; }
public string ContentHtml { get; set; }
public string ShortTitle { get; set; }
public int ArticleCategoryId { get; set; }
public virtual ArticleCategory ArticleCategory { get; set; }
}
public class ArticleCategory
{
public int Id { get; set; }
public int CategoryIndex { get; set; }
public string Name { get; set; }
public virtual ICollection<Article> Articles { get; set; }
}
Note the virtual keyword. EF Code First needs this so it can perform its magic behind the scenes.
Now, if you are working with an Article, you can get all it's category info by doing article.ArticleCategory, and if you have an ArticleCategory you can find out what article it refers to with articleCategory.Articles.Single().
