apeiara / google_maps_api-distance_matrix

Ruby wrapper around the Google Maps Distance Matrix API.

GoogleMapsAPI::DistanceMatrix

This is a wrapper around the Google Maps Distance Matrix API.

Installation

Add this line to your application's Gemfile:

gem 'google_maps_api-distance_matrix'

And then execute:

$ bundle

Or install it yourself as:

$ gem install google_maps_api-distance_matrix

Usage

GoogleMapsAPI::DistanceMatrix.calculate(origins, destinations, options = {})

Origins and destinations are arrays of strings or anything that supports to_ary. Options is a Symbols Hash with optional parameters. (See https://developers.google.com/maps/documentation/distancematrix/#RequestParameters for more information).

For Google Business/Enterprise requests, include the :key, :client and optionally, :channel in the options hash.

Examples:

origins = ["350, 5th Ave, NY", "100, 56th St, NY", [40.764291, -73.979169], ...]
destinations = ["673, 45th St, NY", [40.763641,-73.987473], ...]
options = {:language => 'pt'}
GoogleMapsAPI::DistanceMatrix.calculate(origins, destinations, options)
# => #<GoogleMapsAPI::DistanceMatrix::Response:0x00000001f2b510...>

The GoogleMapsAPI::DistanceMatrix::Response object mimics the API JSON structure.

Contributing

I am new to Ruby and Testing. We need better specs.

1. Fork it ( https://github.com/zavan/google_maps_api-distance_matrix/fork )
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create a new Pull Request

Important

• Do not touch the version;
• Write specs for new features;
• Be independent of Rails stuff;
• All specs must pass.

How do you populate view with map?

Does your helper automatically populate the view with the mapping routes?

Broken API

Hi !

I'm using rails 4.2.6 with Ruby 2.3.0
When attempting to use your gem from rails console:

origins = [[2.85800005014191, 50.4953248662245]] 
destinations =  [[2.85773780193996, 50.49494146317214], [2.854084019245316, 50.48937560068271], [2.867151912465668, 50.495960836073216]] 
options = { key: 'my-api-key', https: true }

It fails:

Cannot require lib

Hi! Cool gem.

I cannot require it though.
I've tried with
gem 'google_maps_api-distance_matrix', '~> 0.2.2', require: true
and
gem 'google_maps_api-distance_matrix', '~> 0.2.2', require: 'google_maps_api'

In both cases I get require': cannot load such file -- ... (LoadError)

I'm using Rails 5.1.2, and Ruby 2.4.1

If you know what I'm doing wrong please let me know. Thank you!

Also, does the gem take care of diving into more than one request in case there are more points than the google allowed dimensions for the cost matrix?
