Instance Method Details

#create(params = {}) ⇒ Object

Return a newly created resource. Some params may be required. Consult the Twilio REST API documentation related to the kind of resource you are attempting to create for details. Calling this method makes an HTTP POST request to @path with the given params

def create(params={})
  raise "Can't create a resource without a REST Client" unless @client
  response = @client.post @path, params
  @instance_class.new "#{@path}/#{response[@instance_id_key]}", @client,
    response
end

#get(sid) ⇒ Object Also known as: find

Return an empty instance resource object with the proper path. Note that this will never raise a Twilio::REST::RequestError on 404 since no HTTP request is made. The HTTP request is made when attempting to access an attribute of the returned instance resource object, such as its #date_created or #voice_url attributes.

end

#list(params = {}, full_path = false) ⇒ Object

Grab a list of this kind of resource and return it as an array. The array includes a special attribute named total which will return the total number of items in the list on Twilio’s server. This may differ from the size and length attributes of the returned array since by default Twilio will only return 50 resources, and the maximum number of resources you can request is 1000.

The optional params hash allows you to filter the list returned. The filters for each list resource type are defined by Twilio.

#total ⇒ Object

Ask Twilio for the total number of items in the list. Calling this method makes an HTTP GET request to @path with a page size parameter of 1 to minimize data over the wire while still obtaining the total. Don’t use this if you are planning to call #list anyway, since the array returned from #list will have a total attribute as well.
