从数据库加载

让我们使用 Repository 尝试更多的加载操作:

import { createConnection } from "typeorm";
import { Photo } from "./entity/Photo";
createConnection(/*...*/)
  .then(async connection => {
    /*...*/
    let allPhotos = await photoRepository.find();
    console.log("All photos from the db: ", allPhotos);
    let firstPhoto = await photoRepository.findOne(1);
    console.log("First photo from the db: ", firstPhoto);
    let meAndBearsPhoto = await photoRepository.findOne({ name: "Me and Bears" });
    console.log("Me and Bears photo from the db: ", meAndBearsPhoto);
    let allViewedPhotos = await photoRepository.find({ views: 1 });
    console.log("All viewed photos: ", allViewedPhotos);
    let allPublishedPhotos = await photoRepository.find({ isPublished: true });
    console.log("All published photos: ", allPublishedPhotos);
    let [allPhotos, photosCount] = await photoRepository.findAndCount();
    console.log("All photos: ", allPhotos);
    console.log("Photos count: ", photosCount);
  })
  .catch(error => console.log(error));
