AAF: find_by_contents on AR Association Total Hits

I seem to be getting some behaviour thats unexpected (for me anyway)
when using find_by_contents on an ActiveRecord has_many association. The
results that are returned are only the records that belong to the model
returned, but the total_hits that are being returned appear to be for
the whole table.

e.g.

class Book < AR::Base
has_many :pages
end

class Page < AR::Base
belongs_to :book
acts_as_ferret :fields => [:content]
end

b1 = Book.create(:title => “Book One”)
b1.page.add(:content => “The cat sat on the mat.”)
b1.page.add(:content => “The cat went for a walk in the country.”)

b2 = Book.create(:title => “Book Two”)
b2.page.add(:content => “Once upon a time in a country quite far away.”)
b2.page.add(:content => “There lived a man with his cat.”)

results = b1.pages.find_by_content("cat)
results.total_hits #=> 3
results.results.length #=> 2

b1.pages.total_hits #=> 3

Is this the expected behviour? Is there any way to get total_hits to
report the total_hits only for the pages belonging to b1?

It will make pagination very difficult otherwise.

Cheers,
Steve

sorry, seems your mail slipped through somehow.

In fact what you are doing is interesting - I never thought of AAF being
used on a has_many collection yet. Looks like in one place the scoping
is working correctly, but when counting the results it doesn’t. As a
work around, use

Page.find_by_contents(query, {}, { :conditions => [“book_id=?”, book.id
] })

to restrict aaf on a special book.

Could you please file a ticket for the enhancement to support calling
aaf directly on collections at

Thanks for the quick reply, in hindsight it could probably have a better
subject!

Page.find_by_contents(query, {}, { :conditions => [“book_id=?”, book.id ] })

Thanks that works great!
