Generates swagger-ui json files for rails apps with APIs. You add the swagger DSL to your controller classes and then run one rake task to generate the json files.
Here is an extract of the DSL from a user controller API class:
swagger_controller :users, "User Management"
swagger_api :index do
summary "Fetches all User items"
param :query, :page, :integer, :optional, "Page number"
response :unauthorized
response :not_acceptable
response :requested_range_not_satisfiable
end
Add this line to your application's Gemfile:
gem 'swagger-docs'
And then execute:
$ bundle
Or install it yourself as:
$ gem install swagger-docs
Create an initializer in config/initializers (e.g. swagger_docs.rb) and define your APIs:
Swagger::Docs::Config.register_apis({
"1.0" => {
:controller_base_path => "api/v1",
:api_file_path => "public/api/v1/",
:base_path => "http://api.somedomain.com"
}
)
class Api::V1::UsersController < ApiController
swagger_controller :users, "User Management"
swagger_api :index do
summary "Fetches all User items"
param :query, :page, :integer, :optional, "Page number"
response :unauthorized
response :not_acceptable
response :requested_range_not_satisfiable
end
swagger_api :show do
summary "Fetches a single User item"
param :path, :id, :integer, :optional, "User Id"
response :unauthorized
response :not_acceptable
response :not_found
end
swagger_api :create do
summary "Creates a new User"
param :form, :first_name, :string, :required, "First name"
param :form, :last_name, :string, :required, "Last name"
param :form, :email, :string, :required, "Email address"
response :unauthorized
response :not_acceptable
end
swagger_api :update do
summary "Updates an existing User"
param :path, :id, :integer, :required, "User Id"
param :form, :first_name, :string, :optional, "First name"
param :form, :last_name, :string, :optional, "Last name"
param :form, :email, :string, :optional, "Email address"
response :unauthorized
response :not_found
response :not_acceptable
end
swagger_api :destroy do
summary "Deletes an existing User item"
param :path, :id, :integer, :optional, "User Id"
response :unauthorized
response :not_found
end
end
