Save multiple values into column - ruby-on-rails

Question

I'm trying to store multiple values retrieved from a JSONP request into my rails database so I can show the different results later.
I've created a function in my controller like this,
movieAdd.trailer(movie.id)
.then(function(response){
$scope.youtubeTrailer = response;
console.log ($scope.youtubeTrailer)
This requests the trailer service in my movieService.js,
var service = {};
var baseUrl = 'http://api.themoviedb.org/3/movie/';
function httpPromise (url) {
var deferred = $q.defer();
$http({
method:'JSONP',
url: url
})
.success(function(data){
deferred.resolve(data);
})
.error(function(){
deferred.reject();
});
return deferred.promise;
}
service.trailer = function(youtube_link){
return httpPromise(
baseUrl + youtube_link + '/videos?api_key=a8f7039633f2065942c**a28d7cadad4&callback=JSON_CALLBACK'
)
};
And I store the results in the youtubeTrailer scope.
Then I have a create function,
createMovie.create({
release_date: $scope.movieListID.release_date,
youtube_link: $scope.youtubeTrailer.key,
imdb_rating: $scope.movieImdbRating.imdbRating,
title: $scope.movieListID.original_title,
image: $scope.movieListID.poster_path,
movie_id: $scope.movieListID.id
}).then(init);
I've added the param to my movies_controller.rb
def movie_params
params.require(:movie).permit(:title, :image, :release_date, :youtube_trailer, :imdb_rating, :movie_id)
end
And I've created a column in my movies table
t.string "youtube_trailer"
But when I check my movies.json it says youtube_trailer":null
To recap, I get this kind of output,
{"id":1893,"results":[
{"id":"533ec65ac3a3685448000a24","iso_639_1":"en","key":"bD7bpG-zDJQ","name":"Trailer 1","site":"YouTube","size":720,"type":"Trailer"},
{"id":"533ec65ac3a3685448000a25","iso_639_1":"en","key":"UgDhFgSTPIw","name":"Trailer 2","site":"YouTube","size":720,"type":"Trailer"}
]}
And I'm trying to store both key values in my database so I can use them later.

Answer 1

You are expecting youtube_trailer but create this field as youtube_link. Please try to match the variable names.
