Django-Ninja APIs - Modern API Development in Django

Github: github.com/bugbytes-io/django...
In this video, we'll build an API using Django-Ninja that allows us to fetch devices, fetch locations, and assign a location to a device.
This video will show django-ninja's use of Schemas - subclasses of Pydantic BaseModels - and the use of decorators to create API endpoints.

Oh wow. I can't believe you're doing a vidoe on Django-ninja again. Thanks very much.

[@bugbytes3923]

Thanks for the support!

[@seydinaoumarsamabaly1806]

I have learned django-ninja on this channel, but I can say this another level. Thank you so much man !

[@bugbytes3923]

Thanks a lot man!!

[@dmitrymikhailovnicepianomu8688]

Thank you! Can’t wait to see the continuation.

[@bugbytes3923]

Thanks a lot!

[@dowletaydogdyyew6360]

Absolutely amazing video, I already fell in love with Django-Ninjas. Thank you so much!

[@bugbytes3923]

Glad to hear that, thanks so much!

[@sebwylleman]

Another banger, love the consistency of this channel

[@bugbytes3923]

Thanks a lot!

[@ahmedivy]

The only thing i miss in fastapi was django like orm, and this was perfect

[@bugbytes3923]

Yes! The Django ORM cannot be beaten!

[@anago7]

I respect you seriously. In my previous company, we introduced Django-ninja. And integrated with Flutter for frontend. Your contribution to django ninja is very impressive. Also I think you have a stubborn philosophy about your works and I advocate it.

[@bugbytes3923]

Thanks a lot for this comment, really appreciate it! I hope django-ninja served your purposes in the previous company - would love to explore Flutter in future videos.

[@fabsync]

super awesome man! Love always your approach. Looking forward to more videos on this series.. !

[@bugbytes3923]

Thanks a lot man!

[@stephancodes]

I really like django extension to populate the slug automatically. I normally created the prepopulated fields in the model admin, but this is much cleaner

[@bugbytes3923]

It's a cool field, for sure!

[@theintjengineer]

BugBytes' Videos are soo goood🤯🤯

[@bugbytes3923]

Thanks so much!

[@blees123]

This is amazing work, keep up the great content.

[@bugbytes3923]

Thanks a lot! Will try my best :D

[@robhafemeister3100]

Amazing how much and how fast I have learned from your videos. I really like django-ninja, FastAPI with the Django ORM.

[@bugbytes3923]

Thanks a lot Rob! And yeah, they're all great options.

[@mahmoudtokura]

This was beautiful to watch. I have always struggled with DRF; this will be my new go-to framework. It allows you to code as you picture it without restrictions or being overly opinionated. In my opinion, this is more pythonic.

[@bugbytes3923]

Thanks for watching! Agreed - more Pythonic and a nicer dev experience!

[@leoe.r.7338]

Great tutorial.

[@bugbytes3923]

Thanks a lot!

[@aashayamballi]

thank you!

[@bugbytes3923]

Thanks a lot for watching!

[@swelanauguste6176]

Thank for the video. I have been waiting for a Django Ninja update video. Could you please do a video on django-extensions and Django-extras, I have seen you using it a few times

[@bugbytes3923]

Thank you. For sure, django-extensions would be worth covering in more detail - thanks for the suggestion!

[@frameff9073]

thank you

[@bugbytes3923]

Thanks for watching!

[@deymonster2u]

Very cool and simple! When will be the next video with React?

[@bugbytes3923]

Thank you! I think the follow-up video will be on Saturday!

[@aek64]

Greate video. I don't know how to make the api calls more secure. Can you use the built-in users that always exist in a Django site? I would love to see this in the next video because security is needed even for basic API:s. Maybe someone has a link to share how it is done.

[@haseeb9621]

[@jhalmu]

Thanks for wideo, I needed this. One question: What diffrence is use django-extras/extensions slug vs djangos slug.field?

[@jamoinmoin]

I don't quite see the benefit of Ninja & Schemas over DRF & serializers. Am I missing something?

[@sagiyoav]

Following

[@bugbytes3923]

My understanding from reading opinions on reddit and other sites - is that a lot of people find serializers/views in DRF quite confusing when you need to go beyond basic CRUD stuff. I think there's a bit of a learning curve to understand its nuances, but I personally love DRF, and of course many others do too. I guess Ninja is just a different approach with less "magic" in the views.

[@shintaii84]

Async async async!

[@keyton_weissinger]

Great video! Thank you. This looks like a great alternative to DRF to add a REST api to an existing Django app, no?

[@bugbytes3923]

Thanks a lot Keyton! That's exactly the use-case I think - if you have a Django app (or want to create one) that needs an API, then this is a nice alternative to DRF!

[@codelabspro]

Can you do a video on authentication with Django-ninja please

[@chengsu8270]

I need authentication too. Thank @bugbytes3923

[@CristianMolina]

Thanks for the video! One question: There are _2_ "get_devices" methods, for devices and locations endpoints but it still works, I assume because of the decorator but the 2nd method doesn't override the first one?

[@bugbytes3923]

Yeah, this was a mistake (corrected in the django-ninja-extra video) - the second function should be called "get_locations()". It must work due to the decorator wrapping the function!

[@kingbabu7373]

In django dynamic addcontanct button using htmx how to get single submitt button to submit multiple forms to database

[@theintjengineer]

In the Schema for Location, you have 'id', 'name'. I get the name part, since it's defined on the model. I also get the id on the Device Schema, since that's also on the Device Model. I just don't get where the id for the locations is coming from, since location has only a single field called 'name'. Thank you, BugBytes 🙌🏽

[@steogen]

I believe the id field is added to all models by default. No need to be set up by the user. It’s necessary for the database to establish a unique primary key for each instance of the model

[@theintjengineer]

@@steogen, oooooh; and he explicitly sets up the id field for Device using uuid4 because he didn't want to have just a simple integer as the id for the devices, right? I get it now. Thank you very much. You're a good person🤝🏾

[@steogen]

@@theintjengineer that’s my understanding too. Glad I could help ☺️

[@richcodesweb]

Trying to create Many-to-Many relationships, you'd have thought that you'd do it in a similar way, `list[str]` but when I try this, I always get an error, saying that fields are missing, that don'e even appear in the schema, or the model ....

[@DhavalAhir10]

Now No need of Django Rest Framework?

[@dimasarestu2043]

Can i use it for existing django app?

[@bugbytes3923]

Yes, definitely!

Hello! I'm having difficulty connecting django 5.0 with the oracle 11g database. Do you know of any solution for this?

[@bugbytes3923]

I've not connected Django to Oracle for a while, so not sure what the issue is - sorry! Do you have any errors/exceptions that you're seeing?

[@leftblank5315]

Please make sure the Instant Client is installed and in the path

[@marcosaugustoschultzwutke6670]

The Instant Client is installed and in the correct path. I have a Laravel application using Instant Client and it works perfectly. I read that Django 5 only works with Oracle version 19 or higher.@@leftblank5315

[@seydinaoumarsamabaly1806]

Hey, to connect Django higher than 3 to oracle you may need Oracle 19c or higher. If you want specifically use your Oracle 11g, you have to downgrade to Django 3.2 or 3.1 or 3.0. Hope this helps !!!

[@marcosaugustoschultzwutke6670]

Thank you.@@seydinaoumarsamabaly1806

[@Septumsempra8818]

Any CI/CD vids coming? I need to know the best strategies to update the database of a production site. Most tuts teach how migrations works and usually just delete them all (even in sql table) when they make a mistake. However, what's the process of taking a prod site, making a whole bunch of migrations (eg. Running field by field indexing effects on speed test) then once the desired migration is found, how do you ensure that only one migration file is created with only the final desired migration set? I like this one-file migration process, but it might not be the best way. Any suggestions on how to optimize migration workflows so as to keep up rolling out new features.

Thank you for promoting Ukrainian products!

Thanks a lot! :)

[@leftblank5315]

I guess FastAPI is no longer modern?

[@bugbytes3923]

FastAPI is what I'd think of when talking about "modern" Python API frameworks - so yes, I'd say it is! Django-Ninja brings that approach to Django.

[@leftblank5315]

@@bugbytes3923 my post was a bit sarcastic. It seems everyday there is a new framework. My point is, why would I learn yet another one, when FastAPI is well-established and is here to stay? Not to mention the author of Ninja is mixing politics into his work

[@bugbytes3923]

​@@leftblank5315 This is specifically for Django apps that might need APIs. If you have a Django app - better to keep your API in Django, make use of the models/ORM, and avoid having a separate FastAPI app just to expose an API over the same data model. Ninja gives an alternative over Django REST Framework for developers that are familiar with, or prefer, the Pydantic/FastAPI way of doing things. Not much new to learn tbh, if you're already a fan of FastAPI. But remember, there are many thousands more web apps running Django than FastAPI - so ninja gives an easy way of migrating towards these new approaches without ditching Django entirely. No idea about the politics of the author. He's Ukrainian I believe, so ....

[@leftblank5315]

@@bugbytes3923 it makes sense in the context of Django. I've used DRF for years.
