I have a method I would like to use for testing that just makes a GET request to a specific url. The parameter for the url is just one parameter with multiple values that can be passed seperated by commas.

an ideal request should have the url look like : url + "/items?item_ids?=1,2,3,4"

My method accepts multiple arguments:

def method(*args) url = url + "/items?item_ids?=#{args}" end

The issue I am having is that it will input the args into the url as an array which does not work. Is there a good way to add the arguments to the url not as an array and only seperated by commas? There will be an unknown number of arguments passed into this method.

You're basically using string interpolation on an array of arguments. You can easily change the array into a string of arguments separated by commas by doing 

def method(*args)
  url = url + "/items?item_ids?=#{args.join(',')}"
end

Get me 99 slayer on Runescape bro ;)

Going by the standard rails convention, and assuming items goes to ItemsController#index action, you can do

#/items?item_ids?=1,2,3,4
def index 
  item_id_list = params[:item_ids]
end

At this point, item_id_list will become a comma seperated string "1,2,3,4" and you can perform any string interpolation fuctions.

E.g if you want all the ids to an array, you can do 

item_id_list.split(",") #=> [1,2,3,4] etc
