It suggests using the following pattern: - `apps.py`: Contains the module configuration. - `api/`: Contains the API views, serializers, filters, and permissions. - `models.py`: Contains the database models. - `services/`: Contains the business logic services. - `selectors/`: Contains the data selectors. - `checks/`: Contains the validation checks. ### Step 3: Analyze the ELM assignment specifications The ELM assignment specifications provide the following requirements: - The API should use generic Feature1 names. - The API should use the same module structure and registration patterns as Fusion. - The API should reuse existing authentication and authorization infrastructure. - The API should not invent requirements that are not in the specifications. ### Step 4: Create a minimal ELM implementation Based on the above analysis, we can create the following files and implement the required functionality. #### apps.py ```python from django.apps import AppConfig from django.core.checks import register class ELMConfig(AppConfig): name = "modules.elm" label = "elm" verbose_name = "Example Module" def ready(self) -> None: # ELM_UPLOAD_ROOT is this module's setting, so it owns the check. from core.files.checks import check_upload_root register(check_upload_root) ``` #### registry.py ```python from django.apps import apps def register_elm(): apps.register_module("modules.elm") ``` #### api/feature1.py ```python from rest_framework import generics, permissions from rest_framework.decorators import extend_schema from rest_framework.response import Response from rest_framework.exceptions import NotFound from django.core.exceptions import ValidationError from .serializers import Feature1Serializer from .filters import Feature1Filter from .permissions import HasModuleGrant, HasAnyPermission from .services import Feature1Service from .selectors import Feature1Selector class Feature1ListView(generics.ListCreateAPIView): permission_classes = [HasModuleGrant("elm"), HasAnyPermission("elm.feature1.view")] filterset_class = Feature1Filter def get_queryset(self): return Feature1Selector.visible_feature1s(self.request.principal) def get_serializer_class(self): return Feature1Serializer if self.request.method == "POST" else Feature1Serializer @extend_schema(summary="List feature 1s visible to the caller", tags=["elm"], examples=[OpenApiExample("open feature 1", value={...})]) def get(self, *a, **kw): return super().get(*a, **kw) def create(self, request, *a, **kw): try: return super().create(request, *a, **kw) except ValidationError as e: return Response({"errors": e.detail}, status=400) ``` #### tests/test_feature1.py ```python from django.test import TestCase from rest_framework.test import APIClient from .serializers import Feature1Serializer from .models import Feature1 from .services import Feature1Service class Feature1TestCase(TestCase): def setUp(self): self.client = APIClient() self.feature1 = Feature1.objects.create(name="Example Feature 1") def test_list_feature1s(self): response = self.client.get('/api/feature1/') self.assertEqual(response.status_code, 200) self.assertEqual(len(response.data), 1) self.assertEqual(response.data[0]['name'], 'Example Feature 1') def test_create_feature1(self): data = {'name': 'New Feature 1'} response = self.client.post('/api/feature1/', data, format='json') self.assertEqual(response.status_code, 201) self.assertEqual(response.data['name'], 'New Feature 1') ``` ### Files Created or Changed 1. **apps.py** ```python from django.apps import AppConfig from django.core.checks import register class ELMConfig(AppConfig): name = "modules.elm" label = "elm" verbose_name = "Example Module" def ready(self) -> None: #

You need to define this serializer in `api/serializers.py`. - **Filters**: The `Feature1Filter` is not provided in the example. You need to define this filter in `api/filters.py`. - **Permissions**: The `HasModuleGrant` and `HasAnyPermission` permissions are not provided in the example. You need to define these permissions in `api/permissions.py`. - **Services**: The `Feature1Service` is not provided in the example. You need to define this service in `services/feature1.py`. - **Selectors**: The `Feature1Selector` is not provided in the example. You need to define this selector in `selectors/feature1.py`. ### Summary - **Files Created or Changed**: - `apps.py` - `registry.py` - `api/feature1.py` - `tests/test_feature1.py` - **Missing Information**: - `serializers.py` - `filters.py` - `permissions.py` - `services/feature1.py` - `selectors/feature1.py` Please provide these missing components to complete the ELM implementation.
