Find all edges pointing back to a vertex in the current path

[utillity]

Hi,

I have the the following path:

Company > has Employees > has User

from user I want to find all "HasRights" Edges which point back to the current company (the user also has rights on other companies).

How can I solve this in Exram?

Code:

	public static IValueGremlinQuery<EmployeeDao> ProjectToEmployeeDao(this IVertexGremlinQuery<EmployeeDbVertex> query)
		=> query.Project(p => p.ToDynamic()
			.By(nameof(EmployeeDao.Employee), q => q)
			.By(nameof(EmployeeDao.Company), q => q.Out<HasDbEdge>().OfType<CompanyDbVertex>().TryGetVertex())
			.By(nameof(EmployeeDao.Role), q => q.Out<HasDbEdge>().OfType<TargetAudienceDbVertex>().TryGetVertex())
			.By(nameof(EmployeeDao.EmployeeUser), q => q.Out<HasDbEdge>().OfType<UserDbVertex>().TryGetVertex())
			.By(nameof(EmployeeDao.LastLogin), q => q.Out<HasDbEdge>().OfType<UserDbVertex>().GetLastLogin().TryGetEdge())
			.By(nameof(EmployeeDao.Approval), q => q.InE<ApprovedDbEdge>().ProjectToApprovedDao().TryGetValue())
			.By(nameof(EmployeeDao.Rights), q => ((IElementGremlinQueryBase)q
					.Out<HasDbEdge>().OfType<CompanyDbVertex>()
					.Out<HasDbEdge>().OfType<UserDbVertex>().OutE<HasRightDbEdge>()
				// TODO filter rights by company, as user can have rights in multiple companies!
				.Where(q2 => q2.InV<CompanyDbVertex>()).ProjectToRightsDetailsDao().TryGetList())))
		.Cast<EmployeeDao>();

I found the answer:

you use .As("some-step-name") to store the current company and then in the where use the same step name to point back to the company:

var q = graph.V<CompanyDbVertex>().As("Comp").Project(p => p.ToDynamic()
	.By(nameof(BaseCompanyDao.Company), c => c)
	.By(nameof(BaseCompanyDao.Employees), c => c.Out<HasDbEdge>().OfType<EmployeeDbVertex>().FilterDeleted()
		.Where(x => x.Status != EmployeeStatusType.Removed && x.Status != EmployeeStatusType.Declined)
		.Project(p2 => p2.ToDynamic()
			.By(nameof(EmployeeDao.Rights), q => q.Out<HasDbEdge>().OfType<UserDbVertex>().OutE<HasRightDbEdge>()
				.Where(q2 => q2.InV().As("Comp")).Values(e => e.Right)))));
Output.WriteLine(q.DebugWithMerge());

Gramlin query looks like this then:

g.V().hasLabel("Company").as("Comp")
.project("Company","Employees")
  .by(__.identity())
  .by(__.out("Has").hasLabel("Employee").not(__.has("IsDeleted",true)).has("Status",neq(5).and(neq(4)))
    .project("Rights")
      .by(__.out("Has").hasLabel("SystemUser","User").outE("HasRight").where(__.inV().as("Comp")).values("Right")))
