DiscourseApi

The Discourse API gem allows you to consume the Discourse API

Installation

Add this line to your application's Gemfile:

gem 'discourse_api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install discourse_api

Usage

Over time this project intends to have a full Discourse API. At the moment there are only a few endpoints available:

client = DiscourseApi::Client.new("http://try.discourse.org")
client.api_key = "YOUR_API_KEY"
client.api_username = "YOUR_USERNAME"

client.ssl(...)                                 #=> specify SSL connection settings if needed

# Topic endpoints
client.latest_topics                            #=> Gets a list of the latest topics
client.new_topics                               #=> Gets a list of new topics
client.topics_by("sam")                         #=> Gets a list of topics created by user "sam"
client.topic(57)                                #=> Gets the topic with id 57

# Search endpoint
client.search("sandbox")                        #=> Gets a list of topics that match "sandbox"

# Categories endpoint
client.categories                               #=> Gets a list of categories
client.category_latest_topics(category_slug: "lounge")  #=> Gets a list of latest topics in a category

# SSO endpoint
client.sync_sso(                                #=> Synchronizes the SSO record
  sso_secret: "discourse_sso_rocks",
  name: "Test Name",
  username: "test_name",
  email: "name@example.com",
  external_id: "2",
  custom_fields: {
    field_1: 'potato'
  }
)

# Private messages
client.private_messages("test_user")            #=> Gets a list of private messages received by "test_user"
client.sent_private_messages("test_user")       #=> Gets a list of private messages sent by "test_user"
client.create_private_message(                  #=> Creates a private messages by api_username user
  title: "Confidential: Hello World!",
  raw: "This is the raw markdown for my private message",
  target_usernames: "user1,user2"
)

You can handle some basic errors by rescuing from certain error classes and inspecting the response object passed to those errors:

begin
  client.create_group({ name: 'NO' })
rescue DiscourseApi::UnprocessableEntity => error
  # `body` is something like `{ errors: ["Name must be at least 3 characters"] }`
  # This outputs "Name must be at least 3 characters"
  puts error.response.body['errors'].first
end

Check out lib/discourse_api/error.rb and lib/discourse_api/client.rb's handle_error method for the types of errors raised by the API.

If your forum has a basic HTTP authentication enabled, set user and password:

client.basic_auth = {
  user: "test",
  password: "secret"
}
