Question

I am sending a multidimensional array using the post method given by the Rack::Test like

post "#{url}.json",:data => [["Company","Website"],["this is the dummy text, with,comma","www.technology.com"],["some company","www.url.com"]]

But in my controller when check my params params[:data] i am receiving it as a single dimensioned array ["Company", "Website", "this is the dummy text, with comma", "www.technology.com", "some company", "www.url.com"]

But i want it to retain it’s property as a multi-dimensional array. I need help to do this.

Answer 1

The Rack::Test methods all have the same signature… and the second param is a hash of params

i.e.

post '/path', params={}, rack_env={}

This is because they’re just URL params – which are typical key/value structures (i.e. a hash)
Why do you need it to be a multi-dimensional array?

EDIT: oh, I get it – you have a single hash with one key (:data)

If it’s still causing you grief you could explicitly call to_param in there

ruby-1.9.2-p180 :003 > h = {:data => [["Company","Website"],["this is the dummy text, with,comma","www.technology.com"],["some company","www.url.com"]]}
 => {:data=>[["Company", "Website"], ["this is the dummy text, with,comma", "www.technology.com"], ["some company", "www.url.com"]]} 
ruby-1.9.2-p180 :004 > h.to_param
 => "data[][]=Company&data[][]=Website&data[][]=this+is+the+dummy+text%2C+with%2Ccomma&data[][]=www.technology.com&data[][]=some+company&data[][]=www.url.com"
