$scope.subject.question.push($scope.questionList[i].id);
error:
Cannot read property 'push' of undefined

Can anyone correct this?

$scope.subject.question

There is no question attribute in subject.
At least not in the code you've posted.

Now the attribute is questions but still the error remains same.

Are you sure?
Because $scope.subject.questions is not "undefined" so I would expect a different error.

I have changed little bit in the structure of questions



$scope.subject .questions.push($scope.subject .questions.description=$scope.questionList[i].id,$scope.subject .questions.questionId=$scope.questionId);
Is this the correct way of doing it ?

Your $scope.subject.questions array contains objects. That means you need to add them as objects:

Post it using an AJAX call to a back-end service, that will do the actual inserting. You can use a JSON or form-style request body.

And  one more question if I call add Question function multiple times in a single session so the data which I have inserted in the last call gets overwrite or it just adds further.

I have thought of posting  subject through http request post to my controller and then saving it in my DB in arraylist format while mapping questions field with another table. Is this a correct way of doing it?

I'm not sure what you mean by that, but it doesn't sound like a good idea to me. I would suggest designing a properly normalized database for a start, and have the back end parse the data it receives and store that data in suitable tables.

Array list I mean to say list of questions I'd would be stored in the table known as subjects and those questions id will be mapped in another table with description id .
