Problem: I have a many-to-many relationship between two custom post types. In a two-column table View, I want to display the title of each post from post type A in the left column. In the right column, I want to display the average value of a custom field in all the related Type B posts.
Solution: There's nothing exactly like this built into the system, so it's probably best to create a custom shortcode that can be used to query related posts and calculate the average custom field value. See examples below.
Problem:
The problem this user is having is that their view isn't returning all the posts in the list. Solution:
In this user's case when the view was checked, they were ordering the view by a custom field.
Unfortunately not all the posts has this custom field filled in which caused them not to appear on the frontend.
It is not possible to sort items that have a null value .
