我有以下功能:
MovieId StartTime
34 08-06-2015 19:00
34 09-06-2015 21:00
34 10-06-2015 20:00
(Dutch DateTime Format)
它工作正常,但where条件不起作用。仍然返回来自具有相同MovieId的timetablerepo的所有记录。 这是什么原因?我做错了什么?这样做的正确方法是什么?
编辑:示例:
我在MovieId = 34的电影中有记录在TimeTable中有3条记录:
Result.Count=6 (That's right)
[0]
MovieId = 2
(Etc..)
TimeTables
[0]
MovieId = 2
StartTime = {5-5-2015 20:00:00}
(Etc..)
[1]
MovieId =2
StartTime = {28-5-2015 20:00:00}
(Etc..)
[1]
MovieId = 13
TimeTables
[0]
MovieId = 13
StartTime = {28-5-2015 21:00:00}
(etc..)
[1]
MovieId = 13
StartTime = {28-5-2015 19:50:00}
(etc..)
(etc..)
鉴于'date'中的日期,我想过滤当天的记录。 (此时此刻重要)。现在我得到了这些记录。
示例2:
日期时间 日期= {8-6-2015 00:00:00}
public partial class Movie
{
public Movie()
{
TimeTables = new HashSet<TimeTable>();
}

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 virtual ICollection<TimeTable> TimeTables { get; set; }

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; }
}
时间表:
>>> socket.gethostbyaddr('8.8.8.8')
('google-public-dns-a.google.com', ['8.8.8.8.in-addr.arpa'], ['8.8.8.8'])
编辑4: 关于TimeTable to Movie的查询也是可能的,但后来我得到了多个电影记录,因为每个电影的时间表中有超过1条记录,而且我的查询不太好,但是如果你有解决方案,我会听到:)
答案 0 :(得分:0)
最终,我认为问题在于您尝试重用数据类来保存View数据。最简单的方法就是创建一组新的类,但这可能会让你:
public IList<Movie> GetMovieTimeTable(DateTime date)
{
var result = movierepo.Movies
.Join(timetablerepo.TimeTables,m=>m.MovieId,tt=>tt.MovieId,
(m,g)=>new Movie{
MovieId=m.MovieId,
... rest of properties here ...
TimeTables=g.Where(tt=>tt.StartDate.Date==date.Date).ToList()
})
.Where(m=>m.TimeTables.Any())
.ToList();
return result;
}
