A quick and easy way to generate pretty API documentation for a Rails application using your (Rspec) controller specs.
Add this line to your application's Gemfile:
gem 'api_doc'
And then execute:
$ bundle
Or install it yourself as:
$ gem install api_doc
The following "decoration" is needed to hang the Rack response object off the
example metadata before it's passed to the after
hook callback. Rspec
apparently used to do this, but now it doesn't, and apidoc desperately needs
this to inspect all the HTTP interactions from Rack.
class RSpec::Core::Example
alias_method :run_after_example_without_response_payload, :run_after_example
def run_after_example
self.metadata[:response] = @example_group_instance.response
run_after_example_without_response_payload
end
end
TODO: put that in a generator, and make the generator work (currently broken for Rails 4)
Prepare your Rails project by running the generator inside your project:
rails g api_doc:install
This will copy over the appropriate assets and mount the engine routes.
Next, add the following to your spec/spec_helper.rb:
require "api_doc/rspec"
Then tag each controller spec that you want to document like so:
describe 'index' do
it 'returns a list of questions', :api_doc => true do
get :index
response.status.should be(200)
end
end
Finally, run rake api:doc
command and visit /api_docs to browse the generated documentation.
