Hi every body.
I have the following association:
offreservice has_and_belongs_to_many :entiteservices
entiteservice belongs_to :commune
In the communes table i have the "lattitude and longitude" columns for
distance calculation with GEOKIT
In Commune Model i have :
acts_as_mappable :default_units => :kms,
:default_formula => :sphere,
:distance_field_name => :distance,
:lat_column_name => :lattitude,
:lng_column_name => :longitude
In Offreservice Model i have:
acts_as_mappable :through => { :entiteservices => :commune }
I am using Geokit to order and filter the list view like the following
in offreservices controller:
#to filter the list
def conditions_for_collection
"distance < 10" if session[:usager_id] != nil
end
#List sorting based on distance
def custom_finder_options
if session[:usager_id] != nil
commune_usager = Usager.find(session[:usager_id]).commune #city
of the current usager
commune_usager_lat = commune_usager.lattitude #lattitude of
current usager's city
commune_usager_long = commune_usager.longitude #longitude of
current usager's city
communes = Commune.find(:all, :origin => [commune_usager_lat,
commune_usager_long],
:conditions => "distance <= 10")
communes.sort_by_distance_from( [commune_usager_lat,
commune_usager_long])
{:order => 'distance ASC', :origin => [commune_usager_lat,
commune_usager_long], :within=>10}
else
{}
end
end
1) How can i show that "distance" calculated by Geokit for each record
on offreservices list view ?
2) May be after that filtering, there is no record matching.
So i wanted to add criteria (check_box with 2 or 3 options) on
Search view which can extend the search on 20 kms (for example or
more...) from the current_usager's (session[:usager_id]) commune.
Any idea on how i can solve those 2 questions?
Thanks in advance for your help
