我正在尝试创建一个简单的GET方法来检索酒店实体的信息,但是在尝试获取评论时卡住了(由用户添加)。在数据库中,Review实体存储有5个属性:
int Id(Primarykey)
int SenderId(User who sent review)
int RecipientId(The hotel reviewed by user)
int point
string comment
评论模型:
public class Review
{
public int Id { get; set; }
public User Sender { get; set; }
public int SenderId {get; set; }
public Hotel Recipient { get; set; }
public int RecipientId { get; set; }
public DateTime DateAdded { get; set; }
public int Point { get; set; }
public string Comment { get; set; }
public bool SenderDeleted { get; set; }
}
酒店的汽车旅馆:
public class Hotel
{
public int Id { get; set; }
public string HotelName { get; set; }
public string Description { get; set; }
public double Price { get; set; }
public string Address { get; set; }
public int Rooms { get; set; }
public int Beds { get; set; }
public int Bathrooms { get; set; }
public string City { get; set; }
public string Country { get; set; }
public bool Status { get; set; }
public ICollection<Review> ReviewsReceived { get; set; }
}
在Myrepository.cs中,我声明了GetHotel函数:
public async Task<Hotel> GetHotel(int id)
{
var hotel = await _context.Hotels.Include(r =>
r.ReviewsReceived).FirstOrDefaultAsync(h => h.Id == id);
return hotel;
}
在HotelsController.cs中:
[HttpGet("{id}")]
public async Task<IactionResult> GetHotel(int id)
{
var hotel = await Myrepository.GetHotel(id);
var hotelToReturn = IMapper.Map<HotelForDetailedDto>(hotel);
return Ok(hotelToReturn);
}
在HotelForDetailedDto.cs中:
public class HotelForDetailedDto
{
public string HotelName { get; set; }
public string Description { get; set; }
public double Price { get; set; }
public string Address { get; set; }
public int Rooms { get; set; }
public int Beds { get; set; }
public int Bathrooms { get; set; }
public string City { get; set; }
public string Country { get; set; }
public bool Status { get; set; }
public ICollection<ReviewForDetailedDto> Reviews { get; set; }
}
在ReviewForDetailDto.cs中:
public class ReviewForDetailedDto
{
public int Id { get; set; }
public int SenderId { get; set; } // userId
public int Point { get; set; }
public string Comment { get; set; }
}
我创建了Map方法进行审核:
CreateMap<Review,ReviewForDetailedDto>();
这就是我收到的:
{
"hotelName": "Dentrex","description": "Eu incididunt pariatur non veniam veniam reprehenderit
cillum adipisicing consequat cillum aliqua in. Ut ut reprehenderit commodo
tempor cillum in sit anim labore in et proident commodo. Fugiat eni.\r\n","price": 2349.79,"address": "Gelston Avenue","rooms": 487,"beds": 2,"bathrooms": 2,"city": "Ronco","country": "Algeria","status": false,"reviews": null
}
所以我想要的是评论应该通过AutoMapper返回在ReviewForDetailD中声明的所有属性。
请帮助。
