You can define to_label for Place model, it will be used for update header
too, like Update <result of place.to_label>
You can define a helper for your place column and get the values:
def place_column(record)
"#{record.street} (#{record.postcode})"
end
If you want to show some fileds from an association in different columns, add
virtual columns to your controller (don't forget to exclude from create and
update columns):
active_scaffold :people do |config|
config.columns << [:place_street, :place_postcode]
[...]
end
Then, add methods to get place_street, place_postcode and so on:
class People < ActiveRecord::Base
def place_street
place.try(:street)
end
def place_postcode
place.try(:postcode)
end
end
