    添加和插入 photo

    现在创建一个新的 photo 存到数据库：

    1. import { createConnection } from "typeorm";
    2. import { Photo } from "./entity/Photo";
    4. createConnection(/*...*/)
    5.   .then(connection => {
    6.     let photo = new Photo();
    7.     photo.name = "Me and Bears";
    8.     photo.description = "I am near polar bears";
    9.     photo.filename = "photo-with-bears.jpg";
    10.     photo.views = 1;
    11.     photo.isPublished = true;
    13.     return connection.manager.save(photo).then(photo => {
    14.       console.log("Photo has been saved. Photo id is", photo.id);
    15.     });
    16.   })
    17.   .catch(error => console.log(error));

    保存实体后，它将获得新生成的 ID。 save方法返回传递给它的同一对象的实例。但它不是对象的新副本，只是修改了它的”id”并返回它。
