Updates to Django

Today, "Updates to Django" is presented by Pradhvan from Djangonaut Space! 🚀

Last week we had 16 pull requests merged into Django by 11 different contributors - including 2 first-time contributors!

Congratulations to somi and Kasey for having their first commits merged into Django - welcome on board! 🥳

This week's Django highlights: 🦄

• Deprecated QuerySet.select_related() with no arguments, along with the corresponding admin options that relied on this implicit form. (#36593)

• RedirectView now supports a preserve_request attribute, letting redirects keep the original HTTP method and body by returning 307 or 308 instead of 302 or 301. (#37062)

• Admin actions are now also shown on the object edit page, allowing bulk actions to be triggered directly from the change form. (#12090)

• Fixed Oracle compound-query compilation by clearing unnecessary ordering from combined query components in unions and ORDER BY wrappers. (#36938)

That's all for this week in Django development! 🐍🦄

Let's say you're writing a Python library.

In this library, you have some collection of state that represents "options" or "configuration" for a bunch of operations. Such a set of options is a bundle of potentially ever-increasing complexity. Thus, you will want it to have an extremely minimal compatibility surface, with a very carefully chosen public interface, that is either small, or perhaps nothing at all. Such an object conveys state and might have some private behavior, but all you want consumers to be able to do is build it in very constrained, specific ways, and then pass it along as a parameter to your own APIs.

By way of example, imagine that you're wrapping a library that handles shipping physical packages.

There are a zillion ways to do it ship a package. There are different carriers who can ship it for you. There's air freight, and ground freight, and sea freight. There's overnight shipping. There's the option to require a signature. There's package tracking and certified mail. Suffice it to say, lots of stuff.

If you are starting out to implement such a library, you might need an object called something like ShippingOptions that encapsulates some of this. At the core of your library you might have a function like this:

1
2
3
4
5

async def shipPackage(
        how: ShippingOptions,
        where: Address,
    ) -> ShippingStatus:
    ...

If you are starting out implementing such a library, you know that you're going to get the initial implementation of ShippingOptions wrong; or, at the very least, if not "wrong", then "incomplete". You should not want to commit to an expansive public API with a ton of different attributes until you really understand the problem domain pretty well.

Yet, ShippingOptions is absolutely vital to the rest of your library. You'll need to construct it and pass it to various methods like estimateShippingCost and shipPackage. So you're not going to want a ton of complexity and churn as you evolve it to be more complex.

Worse yet, this object has to hold a ton of state. It's got attributes, maybe even quite complex internal attributes that relate to different shipping services.

Right now, today, you need to add something so you can have "no rush", "standard" and "expedited" options. You can't just put off implementing that indefinitely until you can come up with the perfect shape. What to do?

The tool you want here is the opaque data type design pattern. C is lousy with such things (FILE, pthread_*_t, fd_set, etc). A typedef in a header file can easily achieve this.

But in Python, if you expose a dataclass - or any class, really - even if you keep all your fields private, the constructor is still, inherently, public. You can make it raise an exception or something, but your type checker still won't help your users; it'll still look like it's a normal class.

Luckily, Python typing provides a tool for this: typing.NewType.

Let's review our requirements:

1. We need a type that our client code can use in its type annotations; it needs to be public.
2. They need to be able to consruct it somehow, even if they shouldn't be able to see its attributes or its internal constructor arguments.
3. To express high-level things (like "ship fast") that should stay supported as we add more nuanced and complex configurations in the future (like "ship with the fastest possible option provided by the lowest-cost carrier that supports signature verification").

In order to solve these problems respectively, we will use:

1. a public NewType, which gives us our public name...
2. which wraps a private class with entirely private attributes, to give us an actual data structure, while not exposing the constructor,
3. a set of public constructor functions, which returns our NewType.

When we put that all together, it looks like this:

from dataclasses import dataclass
from typing import Literal, NewType

@dataclass
class _RealShipOpts:
    _speed: Literal["fast", "normal", "slow"]

ShippingOptions = NewType("ShippingOptions", _RealShipOpts)

def shipFast() -> ShippingOptions:
    return ShippingOptions(_RealShipOpts("fast"))

def shipNormal() -> ShippingOptions:
    return ShippingOptions(_RealShipOpts("normal"))

def shipSlow() -> ShippingOptions:
    return ShippingOptions(_RealShipOpts("slow"))

As a snapshot in time, this is not all that interesting; we could have just exposed _RealShipOpts as a public class and saved ourselves some time. The fact that this exposes a constructor that takes a string is not a big deal for the present moment. For an initial quick and dirty implementation, we can just do checks like if options._speed == "fast" in our shipping and estimation code.

However, the main thing we are doing here is preserving our flexibility to evolve the related APIs into the future, so let's see how we might do that. For example, let's allow the shipping options to contain a concrete and specific carrier and freight method:

from dataclasses import dataclass
from enum import Enum, auto
from typing import NewType

class Carrier(Enum):
    FedEx = auto()
    USPS = auto()
    DHL = auto()
    UPS = auto()

class Conveyance(Enum):
    air = auto()
    truck = auto()
    train = auto()

@dataclass
class _RealShipOpts:
    _carrier: Carrier
    _freight: Conveyance

ShippingOptions = NewType("ShippingOptions", _RealShipOpts)

def shipFast() -> ShippingOptions:
    return ShippingOptions(_RealShipOpts(Carrier.FedEx, Conveyance.air))

def shipNormal() -> ShippingOptions:
    return ShippingOptions(_RealShipOpts(Carrier.UPS, Conveyance.truck))

def shipSlow() -> ShippingOptions:
    return ShippingOptions(_RealShipOpts(Carrier.USPS, Conveyance.train))

def shippingDetailed(
    carrier: Carrier, conveyance: Conveyance
) -> ShippingOptions:
    return ShippingOptions(_RealShipOpts(carrier, conveyance))

As a NewType, our public ShippingOptions type doesn't have a constructor. Since _RealShipOpts is private, and all its attributes are private, we can completely remove the old versions.

Anything within our shipping library can still access the private variables on ShippingOptions; as a NewType, it's the same type as its base at runtime, so it presents minimal¹ overhead.

Clients outside our shipping library can still call all of our public constructors: shipFast, shipNormal, and shipSlow all still work with the same (as far as calling code knows) signature and behavior.

If you need to build and convey some state within your public API, while avoiding breakages associated with compatibility churn, hopefully this technique can help you do that!

Here is a useful trick that is unreasonably effective for simple computer use goals using modern terminal agents. On macOS, there has been a terminal osascript command since the original release of Mac OS X. All you have to do is suggest your agent use it and it can perform any application control action available in any AppleScript dictionary for any Mac app. No MCP set up or tools required at all. Agents are much more adapt at using rod terminal commands, especially ones that haven't changed in 30 years. Having a computer control interface that hasn't changed in 30 years and has extensive examples in the Internet corpus makes modern models understand how to use these tools basically Effortlessly. macOS locks down these permissions pretty heavily nowadays though, so you will have to grant the application control permission to terminal. But once you have done that, the range of possibilities for commanding applications using natural language is quite extensive. Also, for both Safari and chrome on Mac, you are going to want to turn on JavaScript over AppleScript permission. This basically allows claude or another agent to debug your web applications live for you as you are using them.In chrome, go to the view menu, developer submenu, and choose "Allow JavaScript from Apple events". In Safari, it's under the safari menu, settings, developer, "Allow JavaScript from Apple events". Then you can do something like "Hey Claude, would you Please use osascript to navigate the front chrome tab to hacker news". Once you suggest using OSA script in a session it will figure out pretty quickly what it can do with it. Of course you can ask it to do casual things like open your mail app or whatever. Then you can figure out what other things will work like please click around my web app or check the JavaScript Console for errors. Another very important tips for using modern agents is to try to practice using speech to text. I think speaking might be something like five times faster than typing. It takes a lot of time to get used to, especially after a lifetime of programming by typing, but it's a very interesting and a different experience and once you have a lot of practice It starts to to feel effortless.

I have been using macOS voice control for about three years. First it was a way to reduce pain from excessive computer use. It has been a real struggle. Decades of computer use habits with typing and the mouse are hard to overcome! Text selection manipulation commands work quite well on macOS native apps like apps written in swift or safari with an accessibly tagged webpage. However, many webpages and electron apps (Visual Studio Code) have serious problems manipulating the selection, not working at all when using "select foo" where foo is a word in the text box to select, or off by one errors when manipulating the cursor position or extending the selection. I only recently expanded my repertoire with the "start drag" and "drop" commands, previously having used "Click and hold mouse", "move cursor to x", and "release mouse". Well, now I have discovered that using "start drag x" and "drop x" makes a fantastic text selection method! This is really going to improve my speed. In the long run, I believe computer voice control in general is going to end up being faster than WIMP, but for now the awkwardly rigid command phrasing and the amount of times it misses commands or misunderstands commands still really holds it back. I've been learning the macOS Voice Control specific command set for years now and I still reach for the keyboard and mouse way too often.
