Question

I had this service working before, with some other fields, but right now i seem not to get it working, and am not quite getting why.

I’m posting the following json to my Rails app (with RestClient 2.4, for the test) :

{
    "camp":{
        "total": 100,
        "number": "epw1f6e"
    },
    "machine":{
        "serial_number": "1234567",
        "token": "fONxDN"
    }
}

Camp controller :

def create
    if is_it_json?
      logger.debug params.inspect
      machine = Machine.find_by_serial_number(params[:machine][:serial_number])
...

From the logger, I get that params are : {“action”=>”create”, “controller”=>”camp”}

Where is the json information??

My log error :

Started POST "/camps" for 127.0.0.1 at 2012-07-15 00:08:21 +0100
Processing by CampsController#create as JSON
WARNING: Can't verify CSRF token authenticity
{"action"=>"create", "controller"=>"camps"}
Completed 500 Internal Server Error in 2ms

NoMethodError (undefined method `[]' for nil:NilClass):
  app/controllers/camps_controller.rb:24:in `create'

What might i be doing wrong?

Thank you

After a lot of reading and questioning, i just found out the solution :

The params weren’t getting filled because i was missing Headers (I had the Accept, but was missing the Content-type) :

Accept: application/json
Content-type: application/json

Adding the headers solved this issue.
