javascript - AngularJS $resource sending out an extra "registration" hash? -

-

new angularjs here , have trouble getting $resource work. i've created factory , hardcoded $resource object backend needs in order create new plumber.

however, when call function, instead of passing params i've entered, creates 'sort of' duplicate content in form of registration hash, shown in hte backend of app (bolded below). it's exact duplicate of params. did come from???

the create() function called button in plumbers/new.html template

<button data-ng-click="create()">create</button>

where did hash come from???

new.js

angular.module('ngappapp') .controller('plumbersnewctrl', function ($scope, $window, $resource, plumbers) {  $scope.create = function(){   var test1 = new plumbers({     "business[email]": "superhero@super.com",     "business[password]": "123123",     "business[name]": "alice cullen",     "business[company]": "alice pty ltd",     "business[abn]": "12312312",     "business[contact_number]": "0421772800",     "business[address]": "118 glass street",     "business[suburb]": "essendon",     "business[postcode]": "3040",     "business[employees_number]": "8"   });    test1.$save(); };  });  angular.module('ngappapp') .factory('plumbers', function($resource){ return $resource('/businesses'); });

and response backend:

started post "/businesses" 127.0.0.1 @ 2013-08-26 20:40:27 +1000 processing businesses::registrationscontroller#create json parameters: {"business[email]"=>"superhero@super.com", "business[password]"=>"[filtered]", "business[name]"=>"alice cullen", "business[company]"=>"alice pty ltd", "business[abn]"=>"12312312", "business[contact_number]"=>"0421772800", "business[address]"=>"118 glass street", "business[suburb]"=>"essendon", "business[postcode]"=>"3040", "business[employees_number]"=>"8", "registration"=>{"business[email]"=>"superhero@super.com", "business[password]"=>"[filtered]", "business[name]"=>"alice cullen", "business[company]"=>"alice pty ltd", "business[abn]"=>"12312312", "business[contact_number]"=>"0421772800", "business[address]"=>"118 glass street", "business[suburb]"=>"essendon", "business[postcode]"=>"3040", "business[employees_number]"=>"8"}} warning: can't verify csrf token authenticity (0.1ms) begin transaction (0.0ms) rollback transaction completed 400 bad request in 6ms (views: 0.1ms | activerecord: 0.2ms)

edit:

logging test1 shows correct params without 'extra'

resource {business[email]: "superhero@super.com", business[password]: "123123",                                           business[name]: "alice cullen", business[company]: "alice pty ltd", business[abn]: "12312312" business[address]: "118 glass street" business[company]: "alice pty ltd" business[contact_number]: "0421772800" business[email]: "superhero@super.com" business[employees_number]: "8" business[name]: "alice cullen" business[password]: "123123" business[postcode]: "3040" business[suburb]: "essendon"

it's not doubled. rails wrapping params inside of registrations parameter, see both, cause still lets through. i'm writing angularjs app on rails.

btw, why wrapping code that? if want wrap inside of hash need do:

business = {name: "name", blah:"blah"}

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
