Im using DTO's in EntityFrameWork with WebApi 2.0 , so I want to retrieve all the Orders, within the Orders, OrderProducts is a list in my program, I want to retrieve all the OrderProducts related to that Order my code right now is the following:
public async Task < IHttpActionResult > GetOrder() {
var order = from x in db.Order
select new OrderDTO {
OrderId = x.OrderId,
UserId = x.UserId,
orderStatusCode = x.orderStatusCode,
OrderProducts = new List < OrderProductDTO > {
new OrderProductDTO {
OrderId = x.OrderProducts.Select(y = >y.OrderId).FirstOrDefault(),
OrderProductId = x.OrderProducts.Select(y = >y.OrderProductId).FirstOrDefault(),
ProductId = x.OrderProducts.Select(y = >y.ProductId).FirstOrDefault(),
Product = new ProductDTO() {
productDesc = x.OrderProducts.Select(y = >y.Product.productDesc).FirstOrDefault(),
ProductId = x.OrderProducts.Select(y = >y.Product.ProductId).FirstOrDefault(),
productName = x.OrderProducts.Select(y = >y.Product.productName).FirstOrDefault(),
productPrice = x.OrderProducts.Select(y = >y.Product.productPrice).FirstOrDefault(),
}
}
},
purchaseDate = x.purchaseDate,
quantityOrder = x.quantityOrder,
totalOrderPrice = x.totalOrderPrice,
User = new UserDTO {
UserId = x.UserId,
username = x.User.username,
userInfo = new UserInfoDTO {
adress = x.User.UserInfo.adress,
city = x.User.UserInfo.city,
country = x.User.UserInfo.country,
zip = x.User.UserInfo.zip
}
}
};
return Ok(order);
Everything appears to be ok, but when I call the WebApi only the first element is returned, not all the elements in OrderProduct:
Any idea how to retrieve all the OrderProducts? Thanks.
Well you're only populating a single item in your query. Instead, you should do this:
....
OrderProducts = x.OrderProducts.Select(op => new OrderProductDTO
{
OrderId = op.OrderId,
OrderProductId = op.OrderProductId,
//etc
}
....
It looks like you're only asking for one Product instead of a List
Product = new ProductDTO() {
productDesc = x.OrderProducts.Select(y = >y.Product.productDesc).FirstOrDefault(),
ProductId = x.OrderProducts.Select(y = >y.Product.ProductId).FirstOrDefault(),
productName = x.OrderProducts.Select(y = >y.Product.productName).FirstOrDefault(),
productPrice = x.OrderProducts.Select(y = >y.Product.productPrice).FirstOrDefault(),
}
Should probably be
Products = new List<ProductDTO>() {...}
