Models

from django.db import models
class Project(models.Model):
    title = models.CharField(max_length=200)
    description = models.TextField()
    tech_stack = models.JSONField(default=list)
    github_url = models.URLField(blank=True)
    status = models.CharField(
        max_length=20,
        choices=[
            ('planning', 'Planning'),
            ('in_progress', 'In Progress'),
            ('completed', 'Completed'),
        ],
        default='planning'
    )
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    class Meta:
        ordering = ['-created_at']

Serializers

from rest_framework import serializers
from .models import Project
class ProjectSerializer(serializers.ModelSerializer):
    class Meta:
        model = Project
        fields = '__all__'
        read_only_fields = ['created_at', 'updated_at']
    def validate_title(self, value):
        if len(value) < 3:
            raise serializers.ValidationError(
                "Titulo deve ter pelo menos 3 caracteres"
            )
        return value

ViewSets

from rest_framework import viewsets, filters
from rest_framework.pagination import PageNumberPagination
from .models import Project
from .serializers import ProjectSerializer
class StandardPagination(PageNumberPagination):
    page_size = 10
    page_size_query_param = 'page_size'
    max_page_size = 100
class ProjectViewSet(viewsets.ModelViewSet):
    queryset = Project.objects.all()
    serializer_class = ProjectSerializer
    pagination_class = StandardPagination
    filter_backends = [filters.SearchFilter, filters.OrderingFilter]
    search_fields = ['title', 'description']
    ordering_fields = ['created_at', 'title']

Autenticacao

settings.py
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.TokenAuthentication',
    ],
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticatedOrReadOnly',
    ],
}
