I started using MVC 3 and used MvcScaffolding to scaffold these models:
namespace Conference.Models
{
/*
* Speaker can have many session
* And session can have many speakers
*/
public class Speaker
{
public Guid Id { get; set; }
[Required]
public string Name { get; set; }
public string Description { get; set; }
public virtual ICollection<Session> Sessions { get; set; }
}
public class Session
{
public Guid Id { get; set; }
[Required]
public string Title { get; set; }
[Required]
public string Description { get; set; }
[Required]
public DateTime Hour { get; set; }
public virtual ICollection<Speaker> Speakers { get; set; }
}
}
After scaffolding these models, I can create sessions and speakers, but in the speakers view, I cannot choose any sessions, and in the sessions view I cannot choose any speakers.
How can I add these and make them mutliselect options, such that I can choose 10 speakers for one specific session, e.g.?
Thanks in advance, Yosy
You need this in your context class: (this will create an association table)
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Speaker>()
.HasMany(parent => parent.Session)
.WithMany();
}
