for some reason i am unable to loop through all 100 products. i also am unable to use something like @output['products'][0]['images'] to select the image using image_tag. I can use ['products'][0]['name'] etc just not the images or looping.

Could anyone help in what im doing wrong. I tried looping the outer elements first then the inner elements but failed. @output contains 100 results from the api call from webhoseio. (i dont want to use the webhose gem im really trying to grasp an understanding of how to use other gems like httparty or rest-client.)

the format was set to :json

How are you looping through the result. When you say you are unable to loop through, what do you mean exactly, what error are you getting

Did you realise that images is an array?

Hi thanks for the reply. Ive been trying to loop through like so

<% @output['products'].each do |out| %>
<p><% @output['name'] %></p>
<P><% image_tag @output['images'].first %>  </p>
<% link_to 'Show', product[:id]_show_path %> 
<% end %>

ive been using this as a basic template.

In my pagecontentController i have index and show. for index its
def index
          @keyword = "Arduino"
          webhoseio = Webhoseio.new(' # { ENV [ ' APIKEY2 ' ] } ' )
          @output = webhoseio.query('productFilter', {'q': @keyword})
end

def show
         @output['products'][:id]
end

That should be out['images'].first
