Question

Using the following example I’m attempting to retrieve all Jobs where IsAssigned is false.

public class Job {
  public int JobId { get; set; }
  ...
  public virtual ICollection<Bid> Bids { get; set; }
}

public class Bid {
  public int BidId { get; set; }
  public int JobId { get; set; }
  ...
  public bool IsAssigned { get; set; }
  ...
  public virtual Job Job { get; set; }
}

Below is the View method for displaying the available jobs.

public ViewResult AvailableJobs() {
  var jobs = db.Jobs.Include(j => j.Bids.Select(b => b.IsAssigned));
  return View(jobs.ToList());
}

This produces the following error

A specified Include path is not valid. The EntityType ‘MvcTuition.DAL.Bid’ does not declare a navigation property with the name ‘IsAssigned’.

Any ideas of how I can return all Jobs where IsAssigned is false?

Answer 1

Try

var jobs = db.Jobs.Include(j => j.Bids).Where(j => j.Bids.Any(b => b.IsAssigned));
