# Update data
If you had no problems with the Create and Retrieve operations, you should be able to easily understand the logic of updating data. Let's break down the logic into certain steps:
1) Extract the object and write it in a variable.
2) Reassign attributes.
3) Save the changes using the `save()` method

Let's look at the example.

### URL pattern

```python
path("posts/<int:pk>/update/", post_update, name="post-update")
```

### View function

```python
def post_update(request, pk):
    post = Post.objects.get(pk=pk)
    post.title = "Updated Post"
    post.text = "This post was updated"

    post.save()

    return HttpResponse(f"<h1>Post with id {post.id} updated</h1>")
```

The provided code updates the `Post` using `pk` (`id`) received from the URL address.

# Delete Data
To delete data, you just need to extract data and use the `delete()` object method.

### URL pattern

```python
path("posts/<int:pk>/delete/", post_delete, name="post-delete")
```

### View function

```python
def post_delete(request, pk):
    post = Post.objects.get(pk=pk)
    post.delete()

    return HttpResponse(f"Delete Post (id {post.id})")
```

You can see that `None` is displayed instead of post `id`. The fact is that the object was already deleted by the `delete()` method, and, accordingly, it does not have an `id` because it is no longer in the database.

To display the `id` of the deleted object, you can store it in a variable and then output it using `HttpResponse`.

```python
def post_delete(request, pk):
    post = Post.objects.get(pk=pk)
    post_id = post.id  # new
    post.delete()

    return HttpResponse(f"Delete Post (id {post_id})")  # updated
```

Which method help us to submit changes (create and update) in the database?

Which method help us to delete record in the database?

The Django Framework is the best choice to start learning Backend Development using Python! Here you will dive into the Backend, learn how to handle HTTP requests, pass and extract data, and create HTML pages using Templates. In particular, you will learn how to use Python to interact with a database in a very convenient way without using SQL.

This section provides an introduction to Django and its key concepts. It covers the explanation of Django as a web framework, the MVT architectural pattern it follows, and the steps to initialize a new project using Django. The section also includes instructions on running the server.

If you are ready to write your first HTML page on Django - now is the time. Here you can learn how to respond to web requests using the Python programming language.

Do you think that building a database using Python is not possible? It's not true! Let's start to do it with Django!

If you already know how to build a database, then it's time to manipulate data from it. Django ORM is a tool that allows you to work with data from a database. Let's take a look at it, shall we?

The HTTP response as a string doesn't look good. It is worth correcting this by using DTL technology, which allows you to dynamically generate beautiful HTML pages and return them to the user.

You can learn how to answer requests in the previous sections but how to transfer information and process it? Passing data via HTTP request and retrieving is easy. You just have to figure it out, you can find help here.
