使用angularjs将基于类别ID的类别和产品发布到两个不同的表中

Question

我对angularjs很新。 我在我的spinner中有类别列表和产品列表。类别和产品是我的数据库中的两个不同的表作为category_insert和product_insert respiectively.Now当我点击注册类别和产品必须根据“userid”发布到他们各自的表。但是产品是基于categoryids.How我能做到吗？TIA    角度代码：

(function () {
var app = angular.module('MyApp');
app.controller('ProductCtrl', function($scope, $location, $http, ProductService) {
    $scope.productregstr = function() {
        $http ({
            method : 'POST',
            url: 'http://localhost:3000/onio/v1/categoriesinsert',
            data: $scope.category_insert
        });
        // $auth.productregstr($scope.category_insert)
        //     .then(function(response) {
        //         toastr.info('You have successfully created a new account, Please Login');
        //     })
        //     .catch(function(response) {
        //         toastr.error(response.data.message);
        //     });
    };
    $scope.category_insert = {
        categoryname: '',
        categorytype: ''
    };
    $scope.categories = ProductService.getCategory();
    $scope.getCategoryProducts = function() {
        $scope.products = ProductService.getCategoryProducts($scope.category_insert.categoryname);
    };
});
app.factory("ProductService", ['$filter', function($filter) {
    this.categoryList = [
        { "id": 1, "category": "ALL MOVIES, TV SHOWS & MUSIC" }//india:1
    ];
    this.productList = [
        {"Id":1, "product":" All Movies and TV Shows", "categoryId": 1},
        {"Id":2, "product":" Video Games", "categoryId": 1},
        {"Id":3, "product":" All Music", "categoryId": 1}
    ];
    this.getCategory = function() {
        return this.categoryList;
    };
    this.getCategoryProducts = function(categoryId) {
        var products = ($filter('filter')(this.productList, {
            categoryId: categoryId
        },true));
        return products;
    };
    return this;
}]);
})();
