A Ruby client for the 1.0 version of the Asana API.
Supported rubies:
- MRI 2.7.x
- MRI 3.0.x
- MRI 3.1.x
Add this line to your application's Gemfile:
gem 'asana'And then execute:
$ bundle
Or install it yourself as:
$ gem install asana
To do anything, you'll need always an instance of Asana::Client configured
with your preferred authentication method (see the Authentication section below
for more complex scenarios) and other options.
The most minimal example would be as follows:
require 'asana'
client = Asana::Client.new do |c|
c.authentication :access_token, 'personal_access_token'
end
client.workspaces.get_workspaces.firstA full-blown customized client using OAuth2 wih a previously obtained refresh token, Typhoeus as a Faraday adapter, a custom user agent and custom Faraday middleware:
require 'asana'
client = Asana::Client.new do |c|
c.authentication :oauth2,
refresh_token: 'abc',
client_id: 'bcd',
client_secret: 'cde',
redirect_uri: 'http://example.org/auth'
c.faraday_adapter :typhoeus
c.configure_faraday { |conn| conn.use SomeFaradayMiddleware }
end
workspace = client.workspaces.get_workspace(12)
workspace.users
# => #<Asana::Collection<User> ...>
client.tags.create_in_workspace(workspace: workspace.id, name: 'foo')
# => #<Asana::Tag id: ..., name: "foo">All resources are exposed as methods on the Asana::Client instance. Check out
the documentation for each of them.
This gem supports authenticating against the Asana API with either an API token or through OAuth2.
Asana::Client.new do |c|
c.authentication :access_token, 'personal_access_token'
endAuthenticating through OAuth2 is preferred. There are many ways you can do this.
If you have a plain bearer token obtained somewhere else and you don't mind not having your token auto-refresh, you can authenticate with it as follows:
Asana::Client.new do |c|
c.authentication :oauth2, bearer_token: 'my_bearer_token'
endIf you obtained a refresh token, you can use it together with your client credentials to authenticate:
Asana::Client.new do |c|
c.authentication :oauth2,
refresh_token: 'abc',
client_id: 'bcd',
client_secret: 'cde',
redirect_uri: 'http://example.org/auth'
endIf you use omniauth-asana or a browser-based OAuth2 authentication strategy in
general, possibly because your application is a web application, you can reuse
those credentials to authenticate with this API client. Here's how to do it from
the callback method:
# assuming we're using Sinatra and omniauth-asana
get '/auth/:name/callback' do
creds = request.env["omniauth.auth"]["credentials"].tap { |h| h.delete('expires') }
strategy = request.env["omniauth.strategy"]
# We need to refresh the omniauth OAuth2 token
access_token = OAuth2::AccessToken.from_hash(strategy.client, creds).refresh!
$client = Asana::Client.new do |c|
c.authentication :oauth2, access_token
end
redirect '/'
endSee examples/omniauth_integration.rb for a working example of this.
If your application can't receive HTTP requests and thus you can't use
omniauth-asana, for example if it's a CLI application, you can authenticate as
follows:
access_token = Asana::Authentication::OAuth2.offline_flow(client_id: ...,
client_secret: ...)
client = Asana::Client.new do |c|
c.authentication :oauth2, access_token
end
client.tasks.get_task(12)This will print an authorization URL on STDOUT, and block until you paste in the authorization code, which you can get by visiting that URL and granting the necessary permissions.
Whenever you ask for a collection of resources, you can provide a number of results per page to fetch, between 1 and 100. If you don't provide any, it defaults to 20.
my_tasks = client.tasks.get_tasks_for_tag(tag: tag_id, per_page: 5)
# => #<Asana::Collection<Task> ...>An Asana::Collection is a paginated collection -- it holds the first
per_page results, and a reference to the next page if any.
When you iterate an Asana::Collection, it'll transparently keep fetching all
the pages, and caching them along the way:
my_tasks.size # => 23, not 5
my_tasks.take(14)
# => [#<Asana::Task ...>, #<Asana::Task ...>, ... until 14]If you only want to deal with one page at a time and manually paginate, you can
get the elements of the current page with #elements and ask for the next page
with #next_page, which will return an Asana::Collection with the next page
of elements:
my_tasks.elements # => [#<Asana::Task ...>, #<Asana::Task ...>, ... until 5]
my_tasks.next_page # => #<Asana::Collection ...>Because an Asana::Collection represents the entire collection, it is often
handy to just take what you need from it, rather than let it fetch all its
contents from the network. You can accomplish this by turning it into a lazy
collection with #lazy:
# let my_tasks be an Asana::Collection of 10 pages of 100 elements each
my_tasks.lazy.drop(120).take(15).to_a
# Fetches only 2 pages, enough to get elements 120 to 135
# => [#<Asana::Task ...>, #<Asana::Task ...>, ...]In any request against the Asana API, there a number of errors that could
arise. Those are well documented in the Asana API Documentation, and
are represented as exceptions under the namespace Asana::Errors.
The Asana client automatically handles and retries requests upon receipt of
500 (Internal Server Error) responses from the Asana API. If you want to handle
any 4xx errors, you will have to do that yourself; you can do this by rescuing
Asana::Errors::APIError, the parent class of all Asana API errors.
All requests (except DELETE) accept extra I/O options
as documented in the API docs. Just pass an extra options hash to any
request:
client.tasks.get_task(12, options: { expand: ['workspace'] })To attach a file to a task or a project, you just need its absolute path on your filesystem and its MIME type, and the file will be uploaded for you:
task = client.tasks.get_task(12)
attachment = task.attach(filename: '/absolute/path/to/my/file.png',
mime: 'image/png')
attachment.name # => 'file.png'To subscribe to an event stream of a task or a project, just call #events on
it:
task = client.tasks.get_task(12)
task.events # => #<Asana::Events ...>
# You can do the same with only the task id:
events = client.events.for(task.id)An Asana::Events object is an infinite collection of Asana::Event
instances. Be warned that if you call #each on it, it will block forever!
Note that, by default, an event stream will wait at least 1 second between
polls, but that's configurable with the wait parameter:
# wait at least 3 and a half seconds between each poll to the API
task.events(wait: 3.5) # => #<Asana::Events ...>There are some interesting things you can do with an event stream, as it is a normal Ruby Enumerable. Read below to get some ideas.
# Run this in another thread so that we don't block forever
events = client.tasks.get_task(12).events(wait: 2)
Thread.new do
events.each do |event|
notify_someone "New event arrived! #{event}"
end
endTo do that we need to call #lazy on the Events instance, just like with any
other Enumerable.
events = client.tasks.get_task(12).events
only_change_events = events.lazy.select { |event| event.action == 'changed' }
Thread.new do
only_change_events.each do |event|
notify_someone "New change event arrived! #{event}"
end
endYou will receive warning logs if performing requests that may be affected by a deprecation. The warning contains a link that explains the deprecation.
If you receive one of these warnings, you should:
- Read about the deprecation.
- Resolve sections of your code that would be affected by the deprecation.
- Add the deprecation flag to your "asana-enable" header.
You can add global headers, by setting default_headers
c.default_headers "asana-enable" => "string_ids"
Or you can add a header field to the options of each request.
If you would rather suppress these warnings, you can set
c.log_asana_change_warnings false
You'll need Ruby 2.7+ and Node v0.10.26+ / NPM 1.4.3+ installed.
After checking out the repo, run bin/setup to install dependencies. Then, run
bin/console for an interactive prompt that will allow you to experiment.
Run the build with rake. This is equivalent to:
$ rake spec && rake rubocop && rake yard
To install this gem onto your local machine, run bundle exec rake install.
Prerequisite: Before deployment, make sure you have Ruby version 2.7 installed
First, install dependencies:
bundle install
Then, to release a new version, run one of these commands:
rake bump:patch
rake bump:minor
rake bump:major
This will: update lib/asana/version.rb and VERSION, commit and tag the commit. Then you
just need to push --tags to let GitHub Actions build and release the new version to
Rubygems:
git push --tags origin master:master
- Merge in the desired changes into the
masterbranch and commit them. - Clone the repo, work on master.
- Edit package version in
lib/asana/version.rbandVERSIONto indicate the semantic version change. - Commit the change
- Tag the commit with
vplus the same version number you set in the file.git tag v1.2.3 - Push changes to origin, including tags:
git push --tags origin master:master
The specific Asana resource classes (Tag, Workspace, Task, etc) are
generated code, hence they shouldn't be modified by hand. The code that
generates it lives in lib/templates/resource.ejs, and is tested by generating
spec/templates/unicorn.rb and running spec/templates/unicorn_spec.rb as part
of the build.
If you wish to make changes on the code generation script:
- Add/modify a spec on
spec/templates/unicorn_spec.rb - Add your new feature or change to
lib/templates/resource.ejs - Run
rakeor, more granularly,rake codegen && rspec spec/templates/unicorn_spec.rb
Once you're sure your code works, submit a pull request and ask the maintainer to make a release, as they'll need to run a release script.
- Fork it ( https://github.com/[my-github-username]/asana/fork )
- Create your feature branch (
git checkout -b my-new-feature) - Commit your changes (
git commit -am 'Add some feature') - Push to the branch (
git push origin my-new-feature) - Create a new Pull Request
