Many-to-many with class for join entity EF

I'm facing an issue with implementing soft deletes in a custom many-to-many relationship class. I've created a custom class to handle the relationship, but I'm struggling to figure out how to modify the repository's get method to only fetch entities where the relationship's DeletedAt is not null.

c#
public class Role : EntityBase
{
    public required string Name { get; set; }
    public string? Description { get; set; }
    public ICollection<User> Users { get; set; } = [];
    public ICollection<Permission> Permissions { get; set; } = [];
    public ICollection<RolePermission> RolePermissions { get; set; } = [];
    public ICollection<UserRole> UserRoles { get; set; } = [];
}
public class Permission : EntityBase
{
    public required string Name { get; set; }
    public string? Description { get; set; }
    public ICollection<Role> Roles { get; set; } = [];
    public ICollection<RolePermission> RolePermissions { get; set; } = [];
}

public class RolePermission : EntityBase
{

    public required Guid RoleUuid { get; set; }
    public Role? Role { get; set; }
    public required Guid PermissionUuid { get; set; }
    public Permission? Permission { get; set; }
}

public async Task<Role?> GetActiveWithPermissionByIdAsync(Guid uuid)
{
    return await _context.Roles
        .AsNoTracking()
        .Include(r => r.Permissions.Where(p => p.DeletedAt == null))
        .FirstOrDefaultAsync(r => r.Uuid == uuid && r.DeletedAt == null);
}

c#
public class Role : EntityBase
{
    public required string Name { get; set; }
    public string? Description { get; set; }
    public ICollection<User> Users { get; set; } = [];
    public ICollection<Permission> Permissions { get; set; } = [];
    public ICollection<RolePermission> RolePermissions { get; set; } = [];
    public ICollection<UserRole> UserRoles { get; set; } = [];
}
public class Permission : EntityBase
{
    public required string Name { get; set; }
    public string? Description { get; set; }
    public ICollection<Role> Roles { get; set; } = [];
    public ICollection<RolePermission> RolePermissions { get; set; } = [];
}

public class RolePermission : EntityBase
{

    public required Guid RoleUuid { get; set; }
    public Role? Role { get; set; }
    public required Guid PermissionUuid { get; set; }
    public Permission? Permission { get; set; }
}

public async Task<Role?> GetActiveWithPermissionByIdAsync(Guid uuid)
{
    return await _context.Roles
        .AsNoTracking()
        .Include(r => r.Permissions.Where(p => p.DeletedAt == null))
        .FirstOrDefaultAsync(r => r.Uuid == uuid && r.DeletedAt == null);
}

It's cs and not C# for the coloration highlights You also should show you repo methods

I managed to implement soft deletes in the other repositories; they fill the deletedAt field in the RolePermissions class as expected. My issue lies solely in retrieving the Roles with permissions where the association has been deleted.

What is DeletedAt a bool or object or something else?

Kao•8mo ago

Likely a nullable DateTime

Kringe•8mo ago

a ofc thanks

LetieriOP•8mo ago

yep

Kao•8mo ago

So why are you trying to get the roles that have a Deletedaat value here? Wait no Brain farted :KEK: I'm eepy What is the result you have with your current code

LetieriOP•8mo ago

:kekw: It returns the permissions where I deleted the relationship using soft delete.

Kao•8mo ago

Oh but you are going through Permissions instead of RolePermissions I think you need to include RolePermissions.Where(blabla is not null) And then to use the ThenInclude(RP.Roles)

word up I'll test it out Thank you, the problem has been solved, now I just need to solve some mapping problems
