I want to create a query that will return an AgencyContractData object containing a DocumentDto object, but it may be that the original object does not contain a foreign key on the Document. I can't use ternary operator in an Entity-Framwork LINQ query. How it is possible to implement it (Required that select be converted to sql query)?
var contractList = await query
.Select(contract => new AgencyContractData
{
ContractId = contract.Id,
ContractNumber = contract.ContractNumber,
CustomerId = contract.CustomerId,
CustomerName = contract.CustomerName,
Group = contract.Group,
CommodityType = contract.CommodityType,
SupplierName = contract.SupplierName,
StartDate = contract.StartDate,
EndDate = contract.EndDate,
ExecutionDate = contract.ExecutionDate,
ContractUnit = contract.ContractUnit,
Comment = contract.Comment,
Pricing = contract.Pricing,
SecondaryCustomerName = contract.SecondaryCustomerName,
ContractType = contract.ContractType,
AnnualVolume = contract.AnnualVolume,
Document = new DocumentDto
{
DocumentId = contract.Document.Id,
CounterPartyId = contract.Document.CounterPartyId,
FilePath = contract.Document.FilePath,
DocumentTitle = contract.Document.DocumentTitle,
IsCustomerUpload = contract.Document.IsCustomerUpload,
DocumentBytes = null
},
DocumentName = contract.DocumentName,
ContractNumberInt = contract.ContractNumberInt,
ContractNumberString = contract.ContractNumberString,
MsaBaseNumber = contract.MsaBaseNumber,
NotificationDays = contract.NotificationInDays,
State = contract.State,
CreatedOn = contract.CreatedOn,
CreatedBy = contract.CreatedBy,
ModifiedOn = contract.ModifiedOn,
ModifiedBy = contract.ModifiedBy,
It is the AgencyContract entity:
public class Contract : IEntity<long>
{
public long Id { get; set; }
public string ContractNumber { get; set; }
public long? ContractUnitId { get; set; }
public int? NumPricePeriods { get; set; }

public AgencyCommodityTypeEnum CommodityType { get; set; }
public long ContractId { get; set; }

Thank you very much for any help.
CreateMap<EntityEstablishment, EstablishmentDto>()
.ForMember(dest => dest.BookableAreas, opt => opt.MapFrom(src => src.BookableAreas))
.ForMember(dest => dest.Parkings, opt => opt.MapFrom(src => src.Parkings))
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 am trying to insert a data in my local database (SQLited Database) using InsertAsync. But I keep getting this error.
sqlite.sqliteexception: constraint at sqlite.preparedsqlliteinsertcommand.executenonquery
How can I fix and avoid this in the future? Below is my sample code.
var db = DependencyService.Get<ISQLiteDB>();
var conn = db.GetConnection();
try
{
var caf_insert = new CAFTable
{
CAFNo = caf,
EmployeeID = employeenumber,
CAFDate = DateTime.Parse(date),
CustomerID = retailercode,
StartTime = DateTime.Parse(starttime),
EndTime = DateTime.Parse(endtime),
Photo1 = photo1url,
Photo2 = photo2url,
Photo3 = photo3url,
Video = videourl,
GPSCoordinates = actlocation,
Remarks = remarks,
OtherConcern = otherconcern,
RecordLog = recordlog,
LastUpdated = DateTime.Parse(current_datetime)
};
await conn.InsertOrReplaceAsync(caf_insert);
}
catch (Exception ex)
{
Crashes.TrackError(ex);
}
Here is the CAF Table
[Table("tblCaf")]
public class CAFTable
{
[PrimaryKey, MaxLength(50)]
public string CAFNo { get; set; }
[MaxLength(50)]
public string EmployeeID { get; set; }
public DateTime CAFDate { get; set; }
[MaxLength(50)]
public string CustomerID { get; set; }
public DateTime StartTime { get; set; }
public DateTime EndTime { get; set; }
public string Photo1 { get; set; }
public string Photo2 { get; set; }
public string Photo3 { get; set; }
public string Video { get; set; }
public string MobilePhoto1 { get; set; }
public string MobilePhoto2 { get; set; }
public string MobilePhoto3 { get; set; }
public string MobileVideo { get; set; }
[MaxLength(2000)]
public string Remarks { get; set; }
[MaxLength(2000)]
public string OtherConcern { get; set; }
[MaxLength(2000)]
public string GPSCoordinates { get; set; }
[MaxLength(100)]
public string RecordLog { get; set; }
public DateTime LastSync { get; set; }
public DateTime LastUpdated { get; set; }
public int Existed { get; set; }
public int Deleted { get; set; }
public int ThisSynced { get; set; }
public int Media1Synced { get; set; }
public int Media2Synced { get; set; }
public int Media3Synced { get; set; }
public int Media4Synced { get; set; }
}
Make sure the value of caf in your code, that you're trying to insert, does not already exist in the table.

public virtual ICollection<Reservation> Reservations { 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>));
