The easiest way would be to add a new method:
class Foobar
def_dataset_method(:filter_by_name) do |name|
filter(:name=>name.downcase)
end
end
If you absolutely must modify the filter method itself:
class Foobar
def_dataset_method(:filter) do |arg|
return super unless Hash === arg
h = arg.dup
h.keys.each{|k| h[k] = h[k].downcase if k == :name}
super(h)
end
end
I wouldn't recommend that, though, as it only fixes a particular
case. Adding and using a new method is the best solution to the
issue.
