Show Grandchild field in model

[sternalon]

Hi All.
I am new to SQLAdmin. Apologies if this is straightforward.

I have a models named Country, Company and Fees .
The Company model has a "country" has a field country, which is a foreign key pointing at the Country table.
The Fee model has a "company" has a field country, which is a foreign key pointing at the Company table.

I would like to display the country in my fees table (ie: the grandchild). I thought that it would work to add the following to the FeeAdmin: Fee.company.country

So the FeeAdmin looks like
class FeeAdmin(ModelView, model=Fee):
column_list = [Fee.id,
Fee.company,
Fee.company.country,
Fee.percentage]

But it seems that this does not work.

How can I add the grandchildren fields? I guess I could do this using the query field, but I could not find nice examples online.

Thanks
