methods:
```typescript
// here we load one photo by id:
let photoId = 1;
let repository = connection.getRepository(Photo);
repository.findById(photoId).then(photo => {
console.log("Photo is loaded: ", photo);
});
// here we load one photo by name
let repository = connection.getRepository(Photo);
repository.findOne({ name: "Me and Bears" }).then(photo => {
console.log("Photo is loaded: ", photo);
});
// here we load all published photos
let repository = connection.getRepository(Photo);
repository.find({ isPublished: true }).then(photos => {
console.log("Published photos are loaded: ", photos);
});
// here we load one photo by id:
let photoId = 1;
let repository = connection.getRepository(Photo);
repository.findById(photoId).then(photo => {
console.log("Photo is loaded: ", photo);
});
// here we load one photo by name
let repository = connection.getRepository(Photo);
repository.findOne({ name: "Me and Bears" }).then(photo => {
console.log("Photo is loaded: ", photo);
});
// here we load all published photos
let repository = connection.getRepository(Photo);
repository.find({ isPublished: true }).then(photos => {
console.log("Published photos are loaded: ", photos);
});
```
If you want to update in the database a previously loaded photo, you
can use `repository.persist` method:
```typescript
// change previously loaded photo
photo.name = "Me and Bears and Penguins";
photo.description = "I am near polar bears and penguins";
// change previously loaded photo
photo.name = "Me and Bears and Penguins";
photo.description = "I am near polar bears and penguins";
// call persist method to update a photo
let repository = connection.getRepository(Photo);
repository.persist(photo).then(photo => {
console.log("Photo is updated in the database: ", photo);
});
// call persist method to update a photo
let repository = connection.getRepository(Photo);
repository.persist(photo).then(photo => {
console.log("Photo is updated in the database: ", photo);
});
```
If you want to remove a photo from the database, you can use
`repository.remove` method:
```typescript
let repository = connection.getRepository(Photo);
repository.remove(photo).then(() => {
console.log("Photo has been successfully removed.");
});
let repository = connection.getRepository(Photo);
repository.remove(photo).then(() => {
console.log("Photo has been successfully removed.");
});
```
