Hi Johann
If it needs to be an attribute filter, rather than the previous examples using
:conditions on a field, then you should read through this item in the docs:
http://pat.github.com/ts/en/common_issues.html#string_filters
But I think using :conditions and fields is perhaps the way to go. These
approaches are valid whether it's via an association or not. The only tricky
part is matching on exact values from a field in a has_many association - all
values get combined together.
