у меня проблема токая  Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:\Users\орозбек\Desktop\django\tutorial\pythonProject\snippets\serializers.py", line 5, in <module>
    class SnippetSerializer(serializers.Serializer):

    style = serializers.CharField(choices=STYLE_CHOICES, default='friendly', max_length=100)

а это serializers.py

from rest_framework import serializers
from snippets.models import Snippet, LANGUAGE_CHOICES, STYLE_CHOICES


class SnippetSerializer(serializers.Serializer):
    id = serializers.IntegerField(read_only=True)
    title = serializers.CharField(required=False, allow_blank=True, max_length=100)
    code = serializers.CharField(style={'base_template': 'textarea.html'})
    linenos = serializers.BooleanField(required=False)
    language = serializers.ChoiceField(choices=LANGUAGE_CHOICES, default='python')
    style = serializers.CharField(choices=STYLE_CHOICES, default='friendly', max_length=100)

    def create(self, **validated_data):
        return Snippet.objects.create(**validated_data)

    def update(self, instance, validated_data):
        instance.title = validated_data.get('title', instance.title)
        instance.code = validated_data.get('code', instance.code)
        instance.linenos = validated_data.get('linenos', instance.linenos)
        instance.language = validated_data.get('language', instance.language)
        instance.style = validated_data.get('style', instance.style)
        instance.save()
        return instance

I don’t see anything in the docs at Serializer fields - Django REST framework showing that you can use choices with a CharField. I only see where you can use choices with a ChoiceField or a MultipleChoiceField.

Side note: When posting code here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted. (I’ve taken the liberty of modifying your original post to fix this.)

происходит кагда я пишу python manage.py shell
from snippets.serializers import SnippetSerializer

That’s because your definition for the style field is not correct, as mentioned above.

на я же вить всё делаю по документам что я должен изменить

— from Google translate —

Пожалуйста, покажите мне, какая у вас есть документация, в которой говорится, что вы можете использовать атрибут choices с CharField. Я не могу найти ничего, что говорит о том, что это вариант.

— The original English —

Please show me what documentation you have that says that you can use the choices attribute with a CharField. I can’t find anything saying that that is an option.

Nope, that reference is not saying that.

Edited excerpts from that page.

The model:

class Snippet(models.Model):
              ^^^^^^^^^^^^^
...
    style = models.CharField(choices=STYLE_CHOICES, default='friendly', max_length=100)
                   ^^^^^^^^^^^^^^^^^^
...

The serializer:

class SnippetSerializer(serializers.Serializer):
                        ^^^^^^^^^^^^^^^^^^^^^^
...
    style = serializers.ChoiceField(choices=STYLE_CHOICES, default='friendly')
                        ^^^^^^^^^^^^^^^^^^^
...
