Two one-to-one relationships in EF core-CodePudding

I'm trying to configure a one-two-one relationship twice for an entity with the following classes.

public class Team 
{
    ...
    public virtual TeamGraphic TeamLogo { get; set; }
    public virtual TeamGraphic TeamPlayer { get; set; }
}
public class TeamGraphic
{
    ...
    public virtual Team Team { get; set; }
}

TeamGraphics will be image data.

In the datacontext class

modelBuilder.Entity<Team>(t =>
{
    t.HasOne<TeamGraphic>(g => g.TeamLogo)
    .WithOne(t => t.Team);

    t.HasOne<TeamGraphic>(g => g.TeamPlayer)
    .WithOne(t => t.Team);
});

So to put it in words. A team can have one logo, and a team would have one player (image).

But when I try to do a migration, I get the error:

Cannot create a relationship between 'TeamGraphic.Team' and 'Team.TeamPlayer' because a 
relationship already exists between 'TeamGraphic.Team' and 'Team.TeamLogo'. Navigations can 
only participate in a single relationship. If you want to override an existing relationship 
call 'Ignore' on the navigation 'Team.TeamPlayer' first in 'OnModelCreating'.

Is this at all possible to do?

CodePudding user response：

Is full explained on error: "Navigations can only participate in a single relationship." That means you should to create a second Team on TeamGraphic

public class TeamGraphic
{
    ...
    public virtual Team TeamFromTeamLogo { get; set; }
    public virtual Team TeamFromTeamPlayer { get; set; }
}

modelBuilder.Entity<Team>(t =>
{
    t.HasOne<TeamGraphic>(g => g.TeamLogo)
    .WithOne(t => t.TeamFromTeamLogo);

    t.HasOne<TeamGraphic>(g => g.TeamPlayer)
    .WithOne(t => t.TeamFromTeamPlayer);
});

It has sense. If you only have one reverse navigation, TeamGraphic.Team, is ambiguous. "Which one"?
