Anyone have best video on restful API?

Hey! Do anybody know how to display to unauthorized user datetime fileds somewhere in a template in his local timezone??

Inside official docs you can find an entire about setting timezone in Django

I already did. Does nothing. I need some dates and time in my template change dynamically. Depends on users browser timezone.

You need more time then Timezones are not easy 😊 But it's pretty easy to do it also inside the context To know the timezone from the browser you can just use vanilla JS and then with pytz or the new ZoneInfo you can convert times

Hello guys I wana learn django, can you share the good resources for learning?

#Question I have a model that has a foreignkey for User model. And I have to get it's username. To do this, i have overrided the field declaration and set CharField(). But in this way I can only read data but cant create. How can I achive this? Or should I create separate serializers for reading and writing Model.

May I know where to learn django

You can get the username using the user.username

You have a model that have a attribute like user = ... Right?

yes i have a Task model has the field user = Foreignkey(User) If i serialize a task, user is just it's id. I want it's username to be serialized

So i overrided user field in serializer like this: class TaskSerializer(ModelSerializer): user = StringRelatedField() but StringRelatedField is read only

Instead of StringRelatedField() create a new serializer class with a user model and pass it in the user field

If you just want the username you can do it like this user_username=serializers.CharField(null=True, source='user.username')

yes i have a Task model has the field user = Foreignkey(User) If i serialize a task, user is just it's id. I want it's username to be serialized

yes i have a Task model has the field user = Foreignkey(User) If i serialize a task, user is just it's id. I want it's username to be serialized

You can use two ways for implementing serializer for related 1: Class UserSerializer(serializers.ModelSerializer): Class Meta: Model = User Fields = ['username'] Class TaskSerialzer(serializers.Serializer) user = UserSerializer() 2: TaskSerialzer(serializers.Serializer) user = serializers.SerializerMethodField('get_user') def get_user(self, obj): return obj.user.username

Are there any opensource django web applications ? Rest api's

1st way is serializing username but when creating, is_valid() got False and the error message: 'Invalid data. Expected a dictionary, but got int.'

Creating what?

creating model instance ofc

Creating user or other model data that has been used as a foreign key?

other

Share the error message you got.

'Invalid data. Expected a string, but got int.' this is when I use Charfield()

You need a SerializerMethod and that method have to return obj.user.username

it will be a read-only field then.

So just leave the user PK and inside the POST you have to pass the id and that's it

sigh. But I want to serialize user.username, not it's pk

nested serializer then 😊

In this case it serialize username and not pk and I love it. But I cant create model then 💀

u have to override the create django allows u to do everything by using the OOP principles

I did ). But I chose CharField() with it

Which one should I lean first? Database or Django

db

Hi guys I wanna build Online payment system like Stripe and Paypal in Django

Django is not a good idea for that kind of projects

I know but I want to build it in Django for demo purposes

Are you familiar with Django. How good are you at it?

As of know I do not understand how things flow in online payment system

It is not about just Django. There are a lot of work under Payment system. https://www.quora.com/How-hard-is-it-to-build-a-payment-system-like-Paypal. Before diving into creating backend I highly recomment to research first

i wouldn't say that Django is easier than ANY payment system many payment systems have quite a developer-friendly interface (here I don't mean that Django interfaces are complicated, they are complicated as a whole) only poorly organized payment systems and cryptocurrencies can match Django in complexity this is just my personal opinion i implemented integration with one payment system in Django, and my experience with Django and programming in general is rather modest
