We do have a possibility to access any Site on WP Discover, but would you like it when any supporter would have access to any Test Site, which after all is a Private test Site?
This is why the Super Admin access is kept secret and only a few persons in the Company with the right permissions could actually access your Site without asking you permission or details.
I apologize that this might be confusing and time consuming, but it is to protect your Data and to do things on your test site only with previous warning and your agreement.
I also requested the details in advance so to save time.
I had a look at the diagram and the related Post Types.
This Post Type (IPO)
Posts-Contributor Resources Links
Is Child to Post and Contributor Resource, and this is what you can deeply with it.
==> Query the IPO and call the parent posts.
The View you use for this Post Type is set to:
Select posts that are children of the Post where this View is inserted.
This will return (query) all IPO of type Posts-Contributor Resources Links that are Child to any Post or Contributor Resource, if inserted to one of the Post Types.
Since you then call the View for Contributors-Contributor Resources Links in this same view and tell to Select posts that are a children of the Post set by parent View, and this Post type is not Child to Posts-Contributor Resources, there will be no results to return.
This IPO is only child to Contributor and Contributor Resource but those are never queried by Your parent View.
From your Diagram I deduced what you want and will try to explain what you need to do.
EDITOR POST is your central item here.
You have EDITORs and CONTRIBUTORS connected to them
Since you want a many to many relation, you will have a Child Post to EDITOR Post and EDITORs (IPO one)
Then you have another Child Post to again connect EDITOR Post and CONTRIBUTORS (IPO two)
Since contributors can have Resources as well, you will set the Child Post TWO as well to be child to EDITOR Resources.
Now you create your Posts, and then you query CHILD POSTS in the Views.
The first Views will be insert in a Content template which styles the EDITORs Posts.
With this view you can call Editors
Then you also insert the View two with which you can call Contributors and their Resources (depending on the current EDITOR post)
This will automatically return the connected CHILD Posts by the View, in where you can then call the connected Parent Posts.
You will need two Views, there is no way to call a Child Post of a Post if it's not directly insert in the Post, or the View is not returning that Post by query.
Please let me know if you have further questions regarding the issue mentioned in this Thread
Thank you for your patience.
