Question

Take the tutorial YABE as example, in the CRUD, for Post, it can show its related tags, but it can not show its related comments. So how can I let it show its related comments ?

Thanks.

Limitation

The CRUD module only shows bi-directional relationships in one of the
two entities: the one that does not have the mappedBy attribute.

Use the custom tag if you need to.
Something like:

<div id="crudListTable">
    #{crud.table fields:['name','description','comments']}
    #{crud.custom 'description'}
       #{if object.description}${object.description.length() > 50 ? object.description[0..50] + '…' : object.description}#{/if}
    #{/crud.custom}
    #{crud.custom 'comments'}
        #{list items:object.comments, as:'comment'}
            ${comment.description} /
        #{/list}
    #{/crud.custom}
    #{/crud.table}
</div>
