Can you post what you’ve tried? I was just working on this last night,
with great success, so I may be able to help you.

The two different models are Party and volunteer.
I have to find all the volunteers who are near to a party.
Here is mycode

Parties#show
def show
@party = Party.find(params[:id])
@volunteers = Volunteer.near(@party.latitude, @party.longitude,
10, :order => :distance)

end

and
show.html.erb in party views

    <% for volunteer in @volunteers %>
  • <%= link_to volunteer.first_name, volunteer %> (<%= volunteer.distance.round(2) %> miles)
    • <% end %>

But i am getting the following error

undefined method `to_coordinates’ for 17.4359:Float

Got it
it should be @volunteers = Volunteer.near([@party.latitude,
@party.longitude], 10, :order => :distance)

Thank you, venkata! Very little clear and concise documentation out
there and this kind of help is much appreciated!
