Well, the attrwrapper uses getattr to get the value for the field, and
therefore accepts strings instead of the attribute itself.
For instance
DataGrid(fields=[("prettyname","classattr")]).display(value=ModelClassInstance)
works. That is also what the docs show you. I did not know that doing
DataGird(fields=[("prettyname",ModelClass.classattr)]).display(value=ModelClassInstance)
would also work. Thanks for the tip. I'll try it.
