Accessing related models with django-tables2

问题:

Can anyone provide a clear example of how to create a table object using django-tables2 that selects and presents data from multiple related models (ie a relational join)? The documentation implies this is possible, but does not say how.

In normal django the select_related() function works nicely, but I cannot work out how to implement this in django-tables2. I note there are other unanswered questions on similar topics.

First, select_related() is not required to access related data, it is there for performance reasons. For django-tables2, you need to define an accessor. An example is here: https://github.com/bradleyayers/django-tables2/issues/106
