IMPORTANT!

Snipt is going open source. We've toyed with this idea for quite a while, and have finally decided it's the right way to move forward.

A few things:
  • The entire Snipt source code will be released on GitHub under the 3-clause BSD License on Friday, September 10th.
  • While we'd like to think we're perfect, we realize we're only human. By open sourcing the software that runs this website, certain bugs or security flaws may be discovered that could compromise the privacy of your snipts.
  • Only the Lion Burger team will be able to push commits to the Snipt.net site. Contributors should send a pull request to add new features or submit patches.
  • By using this site, you agree not to be too angry or take any legal action against Lion Burger should this whole thing go up in flames some day.
  • Follow us on Twitter for updates.
I agree, close this message

  • ∞ Rails 3 IP Geo Location 
    # Ruby on Rails: Geo Location Gem

# Track where your users are around the globe with the Rails 3 Geo Location Gem. Use hostip.info's free service or get a paid account at maxmind.com. I've found the MaxMind response time to be excellent and the data is more complete accurate - but in a pinch or with a low budget, HostIP looks like a great solution as well.


# == GitHub
http://github.com/chrisyour/geo_location


# == Install
gem install geo_location



# == Use: HostIP (free)

# Configuration (config/initializers/geo_location_config.rb)

unless GeoLocation == nil
  # Use HostIP (free)
  GeoLocation::use = :hostip
end

# Example

ip = GeoLocation.find('24.24.24.24') # => {:city=>"Liverpool", :region=>"NY", :country=>"US", :latitude=>"43.1059", :longitude=>"-76.2099"}

puts ip[:city] # => Liverpool
puts ip[:region] # => NY
puts ip[:country] # => US
puts ip[:latitude] # => 43.1059
puts ip[:longitude] # => -76.2099



# == Use: MaxMind (paid)

# Configuration (config/initializers/geo_location_config.rb)

unless GeoLocation == nil
  # Use Max Mind (paid)
  # For more information visit: http://www.maxmind.com/app/city
  GeoLocation::use = :maxmind
  GeoLocation::key = 'YOUR MaxMind.COM LICENSE KEY'
  # This location will be used while you develop rather than hitting the maxmind.com api
  # GeoLocation::dev = 'US,NY,Jamaica,40.676300,-73.775200' # IP: 24.24.24.24
end

# Example

ip = GeoLocation.find('24.24.24.24') # => {:city=>"Jamaica", :region=>"NY", :country=>"US", :latitude=>"40.676300", :longitude=>"-73.775200"}
