Hi all
I’m having a problem with aaf - i want to do a search and order the
results
by the ferret score. I also want to paginate the results (20 per page),
and
to complicate matters further i have an array of ‘allowed_ids’ - this is
effectively the pool of resources which the search results are limited
to.
So, i want to order by score, pass in some AR conditions, and paginate
the
results. Currently the pagination seems to be breaking.
Here’s an example search, paginated with 1000 per page so it effectively
gets all the results (there are only 67 for this particular search).
I’ve
collected the ids of the results just for illustration purposes:
ferret_results = ActsAsFerret::find(“viola”,
[TeachingObject,LearningObject],
#(ferret) options
{ :page => 1,
:per_page => 1000
},
#find options - need to specify conditions for each searched class
individually
{:conditions => { :teaching_object=>[“resources.id in
(?)”,allowed_ids],
:learning_object=>[“resources.id in (?)”,allowed_ids] }
}
).collect(&:id)
=> [5407, 5427, 5416, 5401, 5411, 5415, 5420, 5421, 5426, 5431, 5435,
5436,
5397, 5403, 5412, 5418, 5419, 5423, 5424, 5429, 5437, 5439, 533, 534,
5405,
5425, 5440, 5402, 5413, 5414, 5417, 5432, 5433, 5438, 5410, 5404, 532,
5399,
5409, 531, 5398, 5400, 5408, 5422, 5428, 5430, 5434, 5406, 5441, 518,
524,
535, 529, 525, 526, 536, 537, 538, 530, 528, 527, 4452, 1709, 5790]
So - if i was to bring the per_page parameter down to 10 then i’d expect
to
get the first 10 ids from the list above, right? But, that’s not what
happens:
ferret_results = ActsAsFerret::find(“viola”,
[TeachingObject,LearningObject],
#(ferret) options
{ :page => 1,
:per_page => 10
},
#find options - need to specify conditions for each searched class
individually
{:conditions => { :teaching_object=>[“resources.id in
(?)”,allowed_ids],
:learning_object=>[“resources.id in (?)”,allowed_ids] }
}
).collect(&:id)
=> [532, 531, 518, 524, 529, 525, 526, 530, 528, 527]
Can anyone tell me if i’m doing something wrong, or a way i can work
around
this?
thanks
max
