.from(swagger_file, create_method_name: :operation_id, include_responses: true, mock_response: false, name_for_module: :path, silent: false, create_constants: false) ⇒ void

Import a Swagger or Open API file and create a Ruby Request Hash file including all requests and responses.
The http methods that will be treated are: 'get','post','put','delete', 'patch'.

Parameters:

  • swagger_file (String)

    . Path and file name. Could be absolute or relative to project root folder.

  • include_responses (Boolean) (defaults to: true)

    . (default: true) if you want to add the examples of responses in the resultant file.

  • mock_response (Boolean) (defaults to: false)

    . (default:false) Add the first response on the request as mock_response to be used.
    In case using nice_http gem: if NiceHttp.use_mocks = true will use it instead of getting the real response from the WS.

  • create_method_name (Symbol) (defaults to: :operation_id)

    . (:path, :operation_id, :operationId) (default: operation_id). How the name of the methods will be generated.
    path: it will be used the path and http method, for example for a GET on path: /users/list, the method name will be get_users_list
    operation_id: it will be used the operationId field but using the snake_case version, for example for listUsers: list_users
    operationId: it will be used the operationId field like it is, for example: listUsers

  • name_for_module (Symbol) (defaults to: :path)

    . (:path, :path_file, :fixed, :tags, :tags_file) (default: :path). How the module names will be created.

  • create_constants (Boolean) (defaults to: false)

    . (default: false) For required arguments, it will create keyword arguments assigning by default a constant.

  • silent (Boolean) (defaults to: false)

    . (default: false) It will display only errors. path: It will be used the first folder of the path to create the module name, for example the path /users/list will be in the module Users and all the requests from all modules in the same file.
    path_file: It will be used the first folder of the path to create the module name, for example the path /users/list will be in the module Users and each module will be in a new requests file.
    tags: It will be used the tags key to create the module name, for example the tags: [users,list] will create the module UsersList and all the requests from all modules in the same file.
    tags_file: It will be used the tags key to create the module name, for example the tags: [users,list] will create the module UsersList and and each module will be in a new requests file.
    fixed: all the requests will be under the module Requests
