添加和插入 photo

添加和插入 photo

现在创建一个新的 photo 存到数据库：

import { createConnection } from "typeorm";
import { Photo } from "./entity/Photo";

createConnection(/*...*/)
  .then(connection => {
    let photo = new Photo();
    photo.name = "Me and Bears";
    photo.description = "I am near polar bears";
    photo.filename = "photo-with-bears.jpg";
    photo.views = 1;
    photo.isPublished = true;

    return connection.manager.save(photo).then(photo => {
      console.log("Photo has been saved. Photo id is", photo.id);
    });
  })
  .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。
