I'm trying to change an existing item quantity using set_item_quantity with the following data ...

{:code=>"GCR_ADMIN", :item_code=>"MEMBERS", :quantity=>"2"}

but it always returns an error as follows...

[{:text=>"A value is required", :id=>"18411299", :code=>"412", :auxCode=>"quantity:isEmpty", :fieldName=>"quantity", :errorType=>"isEmpty"}]

Any idea what I'm doing wrong?

Thanks!

Tom

   Hi Tom -- On the surface, it appears that your params are correct but somehow CG isn't getting the quantity. I've confirmed via our logs that there are no POST params for this API call. So, something's wrong. I can't help further without knowing your code. You'll just have to dig in. Can you log your raw API request locally?

   Some additional info...

   I also have tried using numeric for quantity as is :quantity=>2 which also does not work.

   Also, add_item_quantity does succeed but it ignores the quantity and always adds one to the existing item quantity.

   More info ...

   I am using the cheddargetter_client_ruby from expectedbehavior.

   I have looked at their code and it doesn't seem to be doing anything to mess up the quantity parameter.

   Disclaimer: I am a ruby nuby to be sure so maybe I'm missing something obvious. For example I have no idea what you mean by "Can you log your raw API request locally?" Is this something you do via the web browser?

   Sounds like the wrapper method isn't receiving the params as required. Here's the wrapper method:

   https://github.com/expectedbehavior/cheddargetter_client_ruby/blob/...

   It takes two hashes, the id_hash and the data. Can you post your code for the wrapper method call here?

   Here is my code ...

             data = { :code => plan_code, :item_code => 'MEMBERS', :quantity => @plan_count.to_s }
             logger.info "data = #{data}"
             response = @cg.add_item_quantity(data)

   In this case the plan code and the customer code are the same so that is why I am passing that as the "code"

   I'm not sure what I would need to put in the id_hash. As I said this works but it ignores the quantity.

   Ok, problem solved. It was the issue with id_hash vs data. Now that I have separated the two I'm getting the expected results. Thanks for pointing a real noob in the right direction.

   I know this isn't your domain but it would have helped if the example code in the cheddargetter_client_ruby had included an example of something that required both the id_hash and the data parameter. That's where I got messed up. Of course I did look at their code but by that time I had already gotten it in to my head that everything goes in to the data parameter.

   The other thing that caused me some pain was figuring out the response format from the get_customers call. I am sure I did this in the hardest most convoluted way as there was no example of how you should do it. So in your spare time ... anyway ...

   Thanks again for being a great help!
