Unable to remove a Related Page from the live stage once it has been added to a page

[adunn49]

Summary of set up

I have a page type that extends BasePage on which you can add Related Pages.
The template for my page type loops through $RelatedPagesThrough and outputs them to the view.

Issue

It seems that once a related page has been added and published there is no way to remove it from the live page (other than unpublish or delete the related page).

Steps to reproduce issue

• First add ‘RelatedPage’ and publish it.
• Create ‘Main Page’ and on the Related pages tab, link existing ‘Related Page’.
• Publish Main Page

Observations at this point are that the related page appears on the main page.

Also, looking at the database entries the BasePage_RelatedPages_Live table (many many through table) now has the expected entry linking the two pages, as does BasePage_RelatedPages.

At this point we now try to remove the related page:

• Edit Main page
• Go to the Related pages tab and ‘Unlink’ the related Page.
• Publish Main page again

Inspecting the tables again the entry has been removed from BasePage_RelatedPages but it still exists in BasePage_RelatedPages_Live.

Also, in the CMS the draft view no longer shows the related page but the published one still shows it.

If you publish the page after clicking unlink, does the link get removed from the _Live table?
Also, what version of this module are you reporting this for?

I'm labelling this as a bug for now, but without additional information it won't be prioritised,

@GuySartorelli I am experiencing this issue too. I can confirm that Publishing the related page does not have any effect. (Version 2.11.0)

@GuySartorelli Sorry, just looping back to this. I can also confirm that publishing the page after unlinking does not remove the relevant entry from the _Live table. Using version 2.10.1 of the module.

BasePage just needs adding

private static $cascade_deletes = [
    'RelatedPagesThrough',
];
