Basically the set up I currently have is two sets of custom post types which are:

uc_university and uc_course

I'm having lots of trouble trying to display a course based on a my Advanced Custom Field 'post_object'. I have tried multiple solutions and so far have come up with an example that only allows me to simply display the normal custom post type.

But what I want to do is to limit the custom post types that get displayed by their post_object. Below is where I am up to on my query, but I think I may be going down the wrong route.

I only want to display the post types of uc_course that are linked to the post_object I have set up to uc_university.

<?php
    $args = array(
            'post_type' => 'uc_course',
            'meta_query' => array(
            'relation' => 'OR',
            array(
                'key' => 'uc_university',
                'value' => 'Anglia Ruskin University',
                'compare' => 'NOT LIKE'
            ),
        )
    );
    $query = new WP_Query( $args );
        while ($query->have_posts()) : $query->the_post(); ?>
        <li>
        <a href="<?php the_permalink() ?>"><img src="<?php echo the_field('university_main_image'); ?>" alt="<?php the_title(); ?>Clearing" /></a>
        <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
        <p><?php the_excerpt(); // or the_content(); ?></p>
        </li>

<?php endwhile;wp_reset_postdata(); ?>   

Any help and any ideas would be greatly appreciated! I have attempted all sorts, gone through the WP Codex, but in parts I do not necessarily understand it as meta queries etc do get complicated and I would like some help or help explaining what does what so I'm fully aware of the code.
