How filter IQueryable with filtertypes in mutation

[john2094]

Hi,

I have a mutation that let me publish a content with restrictions to certain users, I have two arguments for mutation, the first is the content data and the second one is the restriction rules input.

The content data looks like

public class ContentInput {
//... many input fields
}

And the input argument for security restricted looks like

public class PrivacyInput {
      [GraphQLType(typeof(FilterInputType<User>))]
      public object users { get; set; }
      [GraphQLType(typeof(FilterInputType<Audience>))]
      public object audiences { get; set; }
 }

My question is how apply the privacy rules filters to a custom IQueryable inside of my mutation. Something like that.

mutation{
   addContent(data:{...},privacy:{users:{name:{startsWith:"Mike"}}}){
    #the selection fields
   }
}

public SimpleImageMutationResult AddContent([ScopedService] DBContext db, ContentInput data, PrivacyInput? privacy)
  {
     //In these lines add my content
     var users = db.Users.ApplyFilters(privacy.users);
     var audiences = db.Users.ApplyFilters(privacy.audiences);
    // Store content data associated to filtered users and audiences
  }

Thanks.
