To display associated models attributes, the doc says to handle them
using virtual columns:
in model
def some_attribute
self.othermodel.some_attribute
end
and then just add :some_attribute to config.columns.
But, what if you want to display a lot of attributes? Your models will
look quite dirty, replicate a lot of code, plus the problems related
to that (renaming/adding/deleting attributes, etc)
Has somebody figured out a cleaner way of doing this?
perhaps something like
config.columns.add "Title" , :column => document.title
