Thank you, Jim. :with => {"@geodist" => 0.0..500.0} instead
of :conditions made filtering work.
But there is still that exception if I try to use each_with_geodist
function:
undefined method `each_with_geodist' for #<WillPaginate::Collection:
0x7fdffaca52d8>
I use :order => "@geodist ASC" parameter in search call. And sorting
actually works! But there's no way to get to 'each_with_geodist'
function to retrieve distances from Sphinx. Currently I calculate
these distances in ruby. But that's not the wright way to do it.
Maybe there's some another trick that can make it work?
My current code looks like this:
@location = Location.find @search.location_id
lat, lon = @location.lat * Math::PI/180, @location.lon * Math::PI/
180
@ads = Ad.search(
@search.query,
:conditions => @search.conditions,
:per_page => @search.per_page, :page => params[:page],
:geo => [lat, lon],
:order => "@geodist ASC",
:include => {:subcategory => :category},
:with => {"@geodist" => [email protected]_distance_in_meters}
)
#...@dist = {}
#[email protected]_with_geodist do |ad, dist|
#...@dist[ad.id] = dist
#end
@distances = {}
@ads.each do |ad|
@distances[ad.id] = @search.distance_from_to @location,
ad.location
end
Thanks.
