Ordering posts by distance to city using geocoder

Question

I am trying to order my posts by how close they are to the location of the current user using geocoder. Here is the controller:

def top
@city = request.location.city
@closepost = Post.near(@city, order: :distance)
end

and here is the view:

<% @closepost.each do |post| %>
 <%= post.title %>
<% end %>

I am getting this error:

undefined method `to_f' for {:order=>:distance}:Hash

Answer 1

in controller you define:

@closepost

while in view you are calling:

@closeposts

and you call .each on a variable that is not defined.

update

irb> a=Geokit::Geocoders::GoogleGeocoder.geocode '140 Market St, San Francisco, CA' 
irb> a.ll 
=> 37.79363,-122.396116

@closeposts = Post.within(5, :origin => @city.ll).order('distance DESC') 

with geocode

@closeposts = Post.near('dublin', 50, :order => :distance)

You missed the distance parameter
