Documentation Best Practices

1. Write Clear Descriptions

@extend_schema(    summary='Short, action-oriented summary',  # Good: "Create article"    description="""    # Longer Description        Provide more context here. Explain:    - What the endpoint does    - When to use it    - Important considerations    """,)

2. Include Examples

@extend_schema(    examples=[        OpenApiExample(            name='Common Use Case',            description='Explanation of this example',            value={'field': 'value'},        ),        OpenApiExample(            name='Edge Case',            description='Less common but important example',            value={'field': 'special_value'},        ),    ],)

3. Document All Error Cases

@extend_schema(    responses={        200: SuccessSerializer,        400: 'Validation error - explain what causes this',        401: 'Not authenticated - explain auth requirement',        403: 'Permission denied - explain required permissions',        404: 'Not found - explain what resource',        429: 'Rate limited - explain limits',    },)

4. Use Tags for Organization

@extend_schema(    tags=['Articles', 'CRUD'],  # Multiple tags for better organization)

5. Document Field Constraints

class ArticleSerializer(serializers.ModelSerializer):    title = serializers.CharField(        max_length=200,        help_text='Article title (max 200 characters, required)',    )    content = serializers.CharField(        min_length=100,        help_text='Article content in Markdown (min 100 characters)',    )

6. Keep Documentation Up-to-Date

# Use pre-commit hooks to validate schema# .pre-commit-config.yamlrepos:  - repo: local    hooks:      - id: validate-openapi-schema        name: Validate OpenAPI Schema        entry: python manage.py spectacular --validate        language: system        pass_filenames: false

7. Version Your Documentation

# urls.pyurlpatterns = [    path('api/v1/schema/', SpectacularAPIView.as_view(), name='schema-v1'),    path('api/v2/schema/', SpectacularAPIView.as_view(), name='schema-v2'),        path('api/v1/docs/', SpectacularSwaggerView.as_view(url_name='schema-v1'), name='docs-v1'),    path('api/v2/docs/', SpectacularSwaggerView.as_view(url_name='schema-v2'), name='docs-v2'),]
