angularjs - Angular POST request not formatting correctly -

i have angular form looks this:

<form ng-submit="createnewquestion()" name="createnewquestionform">   <div class="form-group">     <textarea class="form-control" rows="3" ng-model="question.question" placeholder="add question here."></textarea>   </div>   <div class="form-group">     <textarea class="form-control" rows="3" ng-model="question.answer" placeholder="add answer here."></textarea>   </div>   <button type="submit" class="btn btn-default">next</button> </form> 

it submits createnewquestion() function in controller, looks this:

$scope.createnewquestion = function () {   $scope.question.droplet_id = $scope.createddroplet.id; //add droplet_id form data   question.create($scope.question).success(function(question) {     $scope.questions.push(question); //return question , put in helps variable     $scope.question = {}; // clear form   }); }; 

this calls factory post request looks this:

app.factory('question', ['$http', function($http) {   return {     create: function (question) {       return $http.post('/questions/', question)     }   } }]); 

the request gets made on submit params in wrong format. log looks this:

processing questionscontroller#create html   parameters: {"question"=>"some_question", "answer"=>"some_answer", "droplet_id"=>785} completed 500 internal server error in 3ms  nomethoderror (undefined method `permit' "vhjkhfjhgfjhg":string): 

here's weird thing. have identical code copy , pasted forms , functions sends data in correct format rails backend, be:

parameters: {"question"=>"question", "answer"=>"answer", "drop_id"=>485, "question"=>{"question"=>"question", "answer"=>"answer", "drop_id"=>485}} 

the fields different code literally identical. why 1 working while other not , how can fix it?

update

it seems naming issue on backend, request okay. if remove require(:question) from:

params.require(:question).permit(:question, :answer, :droplet_id, :ordering) 

it works. seems doesn't model name being same 1 of attributes.

the problem not request way rails backend handled request. because model name name of 1 of columns became confused , not transform request right format through strong params.

the solution change column name. after that, worked fine.
