Project has moved to gitlab https://gitlab.com/greendevilapps/weather_underground_api

This is a simple class object that uses the Weather Underground API.

Add this line to your application's Gemfile:

gem 'weather_underground_api'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install weather_underground_api

Create a new class by passing in your api key

@wu = WeatherUndergroundApi::Base.new(API_KEY)

Supported options:

• raise_errors: Will raise an error when true or just return the error message when false, when calling the helper method response_has_error?. (defaults: false).
• raise_api_error: If no key passed in during initialization and this is set to true it will raise an error.
• format: The format that you wish to do all of the calls by. Only supported option right now is json.
• lang: Language to be used. (defaults: 'EN').
• pws: Use personal weather stations for conditions. (defaults: '1')
• bestfct: Use Weather Underground Best Forecast for forecast. (defaults: '1')
• icon_set: The icon set to use. See weather underground icon sets for more details.

Checking api key

Check the api key

$ @wu.api_key
=> API_KEY

Checking options

Check the options that are currently being used

$ @wu.options
=> {:raise_errors=>false,:raise_api_error=>true,:format=>"json",:lang=>"EN",:pws=>"1",:bestfct=>"1",:icon_set=>"k"}

Checking for errors

Pass in the object that is returned for the api call.

This will return nil if there is no error. If there is an error it will either raise and error or return the error message (this is configured on initialization).

@wu.response_has_error?(response)
=> nil

Icon set url

This will return a url string for the source of weather underground's api icon sets.

@wu.icon_url('partlycloudy')
=> "http://icons.wxug.com/i/c/k/partlycloudy.gif"
