Question

I am able to use the basic map display capabilities in gmaps4rails with mongoid, which is great, but Im falling short with more advanced features. I think I am missing some basics and looking for guidance.
I am able to get the basic geocoding to work with fields named :latitude :longitude and :gmaps but when I try to use an array, as suggested by the readme, I am getting nowhere. I’ve read the Mongoid tips in the wiki to no avail.

Can anyone point me in the right direction?

Update;
Since Ive gotten no responses, here is some code examples,

The Model

working;

class Account
  include Mongoid::Document
  include Gmaps4rails::ActsAsGmappable
  acts_as_gmappable

  field :account_no
  field :owner_name
  field :address
  field :latitude,  :type => Float
  field :longitude, :type => Float
  field :gmaps,     :type => Boolean

  def gmaps4rails_address
    "#{self.address}"
  end

end 

Not working

 class Account
  include Mongoid::Document
  include Gmaps4rails::ActsAsGmappable
  acts_as_gmappable :position => :location

  field :account_no
  field :owner_name
  field :address
  field :location, :type => Array

  def gmaps4rails_address
  "#{self.address}"
  end

end 

Based on the code snippets in the gmaps4rails readme this should work to geocode the address into the location array but I get this error

NoMethodError: undefined method `gmaps' for #<Account:0x007fc47d051ba0>

Answer 1

As explained here, gmaps is a boolean which purpose is to prevent multiple geocoding of the same address.

So the field is necessary, unless you tell it explicitly (see same doc)
