I have a project where users can search for results within a specified distance of their location, eg within 10 miles of their postcode. I am using geokit-rails for this and it works great using the simple:
.within(@distance, :origin => @latlng)
However there are some results that are not dependant on location so I would like them to always appear in the search, this will be denoted by a bit property called 'remote' set to 1 if it should be included.
So what I need to do is be able to search for all results where the Distance is less than X OR remote equals 1.
Is there any way to do this, or will I have to make 2 db calls and merge the results?
Many thanks
distance attribute was removed from the lib, but there are some workaround about how include again, already included can add a condition for your attribute distance with the attribute remote.
module Geokit::ActsAsMappable
module ClassMethods
# Overwrite Geokit `within`
def within(distance, options = {})
options[:within] = distance
# Have to copy the options because `build_distance_sql` will delete them.
conditions = distance_conditions(options.dup)
sql = build_distance_sql(options)
self.select(
"#{sql} AS #{self.distance_column_name}, #{table_name}.*"
).where(conditions)
end
# Overwrite Geokit `by_distance`
def by_distance(options = {})
sql = build_distance_sql(options)
self.select("#{sql} AS #{self.distance_column_name}, #{table_name}.*"
).order("#{self.distance_column_name} ASC")
end
private
# Copied from geokit-rails/lib/geokit-rails/acts_as_mappable.rb
# Extract distance_sql building to method `build_distance_sql`.
def build_distance_sql(options)
origin = extract_origin_from_options(options)
units = extract_units_from_options(options)
formula = extract_formula_from_options(options)
distance_sql(origin, units, formula)
end
end
end
