Harvested: A Ruby Harvest API

This is a Ruby wrapper for the Harvest API.


gem install harvested


harvest = Harvest.client('yoursubdomain', 'yourusername', 'yourpassword')
harvest.projects.all   # list out projects

client = Harvest::Client.new(:name => "Billable Company LTD.")
client = harvest.clients.create(client)
harvest.clients.find(client.id) # returns a Harvest::Client

You can also pass query options in as the last parameter on any objects all finder method, for example to find all the projects for client ID 12345:

harvest = Harvest.client('yoursubdomain', 'yourusername', 'yourpassword')
harvest.projects.all(nil, :client => 12345)

Note, the second parameter is a User ID field that is optional, but needs to be specified as nil if not included.

You can pass in any hash of query attributes you wish as per the Harvest API page.

You can find more examples in /examples and in the documentation for Harvest::Base

Hardy Client

The guys at Harvest built a great API, but there are always dangers in writing code that depends on an API. For example, HTTP Timeouts, Occasional Bad Gateways, and Rate Limiting issues need to be accounted for.

Using Harvested#client your code needs to handle all these situations. However you can also use Harvested#hardy_client which will retry errors and wait for Rate Limit resets.

harvest = Harvest.hardy_client('yoursubdomain', 'yourusername', 'yourpassword')
harvest.projects.all   # This will wait for the Rate Limit reset if you have gone over your limit

Ruby support

Harvested's tests are currently passing for 1.8.7, 1.9.2, JRuby 1.6.2, and Rubinius

How to Contribute

If you find what looks like a bug:

  1. Check the GitHub issue tracker to see if anyone else has had the same issue. http://github.com/zmoazeni/harvested/issues/
  2. If you don’t see anything, create an issue with information on how to reproduce it.

If you want to contribute an enhancement or a fix:

  1. Fork the project on github http://github.com/zmoazeni/harvested
  2. Make your changes with tests
  3. Commit the changes without messing with the Rakefile, VERSION, or history
  4. Send me a pull request

Note on running tests: most specs run against a live Harvest account. To run the suite, sign up for a free trial account and fill out /spec/support/harvest_credentials.yml (a sample harvest_credentials.example.yml has been included).

DO NOT USE YOUR NORMAL CREDENTIALS IN /spec/support/harvest_credentials.yml!!! The test suite blasts all the data before running (similiar to DatabaseCleaner).

The tests use VCR to cache the API responses. This is a great boon for running the tests offline. While uncommon, sometimes the Harvest API will send an erroneous response, VCR will cache it, and subsequent runs will use the incorrect cached response. In order to clear the cached responses, you can run the specs with the VCR_REFRESH environmental variable set to true (e.g. VCR_REFRESH=true bundle exec rake spec).

Using rvm you can run the tests against the popular ruby runtimes by running:


Each runtime needs to be installed in rvm along with the bundler gem.

Notes on Harvest Estimates

Estimates aren't currently supported due to lack of an API. If this opens up, harvested will include them.
