Configure

If you are not using Rails:

require 'disqus_api'

DisqusApi.config = {api_secret: 'secret key',
                    api_key: 'public key',
                    access_token: 'token from app settings'}

For Rails users:

Put in your config/disqus_api.yml:

development:
  api_secret: development_secret_key
  api_key: 'public key'
  access_token: 'token from app settings'

production:
  api_secret: production_secret_key
  api_key: 'public key'
  access_token: 'token from app settings'

# ... any other env

Enjoy

DisqusApi.v3.users.details
# => {"code" => 0, "response" => {
#                     "isFollowing"=>false,
#                     "isFollowedBy"=>false, "connections"=>{}, "isPrimary"=>true, "id"=>"84792962"
#                     ...
#                  }

Use response to get response body

DisqusApi.v3.users.details.response
# => {
#       "isFollowing"=>false,
#       "isFollowedBy"=>false, "connections"=>{}, "isPrimary"=>true, "id"=>"84792962"
#       ...
#    }

Alias #body for response body

DisqusApi.v3.users.details.body
# => {
#       "isFollowing"=>false,
#       "isFollowedBy"=>false, "connections"=>{}, "isPrimary"=>true, "id"=>"84792962"
#       # ...
#    }

Setting additional parameters to a query

DisqusApi.v3.posts.list(forum: 'my_form')

Fetching full collections

By default Disqus API limits returning collections by 25 records per requests. The maximum limit you can set is 100. In order to fetch all records from a collection use #all method:

DisqusApi.v3.posts.list(forum: 'my_form').all

Pagination

Step by step:

first_page  = DisqusApi.v3.posts.list(forum: 'my_forum', limit: 10)

second_page = first_page.next
third_page  = second_page.next
first_page  = third_page.prev.prev
# ...

It is useful to go through all records. This way you will pass every page in batches by 10:

DisqusApi.v3.posts.list(limit: 10).each_resource do |comment|
  puts comment.inspect
end

You can also iterate collection page by page.

DisqusApi.v3.posts.each_page do |comments|
  comments.each do |comment|
    puts comment.inspect
  end
end

You can also move on next page:

response = DisqusApi.v3.posts
response.next!

Or on previous one:

response.prev!

Performing custom requests

DisqusApi.v3.get('posts/list.json', forum: 'my_forum')
DisqusApi.v3.post('posts/create.json', forum: 'my_forum')

Handling exceptions

Just catch DisqusApi::InvalidApiRequestError. It has code to identify problems with a request.

begin
  DisqusApi.v3.posts.list(forum: 'something-wrong')
rescue DisqusApi::InvalidApiRequestError => e
  e.response.inspect
end

#=> {"code"=>2, "response"=>"Invalid argument, 'forum': Unable to find forum 'something-wrong'"}

Using in test environment

before :all do
  # You can move this block in RSpec initializer or `spec_helper.rb`

  DisqusApi.stub_requests do |stub|
    stub.get('/api/3.0/users/details.json') { [200, {}, {code: 0, body: {response: :whatever}}.to_json] }
  end
end

it 'performs requests' do
  DisqusApi.v3.users.details['code'].should == 0
end

Disqus API uses Faraday gem, refer to its documentation for details.

Contributing to disqus_api

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
