URL with decimals. How to allow in routes?

Rails
1

Hi,

I have a resource that can take latitue and longitude. I have defined
those in the DB as:

t.decimal :lat, :precision => 15, :scale => 10
t.decimal :lng, :precision => 15, :scale => 10

I have set the route so I can pass those in a restful way:

map.nearby ‘/messages/nearby/:lat/:lng/:range/’,
:controller => ‘nearbies’,
:action => ‘index’,
:conditions => {:method => :get}

So I can pass a URL like:
http://127.0.0.1.:3000/messages/nearby/0,4/1,3/73

However the 0,4 and 1,3 are strings and when they are used for latitude
and longitude they become 0.0 and 1.0

I see two options:

1- Convert 0,4 to 0.4 (I need decimal, :precision => 15, :scale => 10)
2- Allow decimals in the URL (…messages/nearby/0.4/1.3/73)

Is option #2 possible?
Any hints to realize any of them?
I have not succeeded converting the string…

Thanks

1- Convert 0,4 to 0.4 (I need decimal, :precision => 15, :scale => 10)

Went for option #1:

fixlat = params[:lat].gsub(/[,]/, ‘.’)
fixlat.to_f

So far looks ok.

Cheers.
