Development URLs

• Frontend: http://demo.lvh.me:5173 (or any business subdomain)
• Platform Frontend: http://platform.lvh.me:5173
• Backend API: http://lvh.me:8000/api/

Note: lvh.me resolves to 127.0.0.1 - required for subdomain cookies to work.

CRITICAL: Backend Runs in Docker

NEVER run Django commands directly. Always use Docker Compose:

cd /home/poduck/Desktop/smoothschedule2/smoothschedule

# Run migrations
docker compose -f docker-compose.local.yml exec django python manage.py migrate

# Django shell
docker compose -f docker-compose.local.yml exec django python manage.py shell

# View logs
docker compose -f docker-compose.local.yml logs -f django

# Any management command
docker compose -f docker-compose.local.yml exec django python manage.py <command>

Core Mixins & Base Classes

Located in smoothschedule/core/mixins.py. Use these to avoid code duplication.

Permission Classes

from core.mixins import DenyStaffWritePermission, DenyStaffAllAccessPermission, DenyStaffListPermission

class MyViewSet(ModelViewSet):
    # Block write operations for staff (GET allowed)
    permission_classes = [IsAuthenticated, DenyStaffWritePermission]

    # Block ALL operations for staff
    permission_classes = [IsAuthenticated, DenyStaffAllAccessPermission]

    # Block list/create/update/delete but allow retrieve
    permission_classes = [IsAuthenticated, DenyStaffListPermission]

Per-User Permission Overrides

Staff permissions can be overridden on a per-user basis using the user.permissions JSONField. Permission keys are auto-derived from the view's basename or model name:

Permission Class	Auto-derived Key	Example
DenyStaffWritePermission	can_write_{basename}	can_write_resources
DenyStaffAllAccessPermission	can_access_{basename}	can_access_services
DenyStaffListPermission	can_list_{basename} or can_access_{basename}	can_list_customers

Current ViewSet permission keys:

ViewSet	Permission Class	Override Key
ResourceViewSet	DenyStaffAllAccessPermission	can_access_resources
ServiceViewSet	DenyStaffAllAccessPermission	can_access_services
CustomerViewSet	DenyStaffListPermission	can_list_customers or can_access_customers
ScheduledTaskViewSet	DenyStaffAllAccessPermission	can_access_scheduled-tasks

Granting a specific staff member access:

# Open Django shell
docker compose -f docker-compose.local.yml exec django python manage.py shell

from smoothschedule.users.models import User

# Find the staff member
staff = User.objects.get(email='john@example.com')

# Grant read access to resources
staff.permissions['can_access_resources'] = True
staff.save()

# Or grant list access to customers (but not full CRUD)
staff.permissions['can_list_customers'] = True
staff.save()

Custom permission keys (optional):

class ResourceViewSet(ModelViewSet):
    permission_classes = [IsAuthenticated, DenyStaffAllAccessPermission]
    # Override the auto-derived key
    staff_access_permission_key = 'can_manage_equipment'

Then grant via: staff.permissions['can_manage_equipment'] = True

QuerySet Mixins

from core.mixins import TenantFilteredQuerySetMixin, UserTenantFilteredMixin

# For tenant-scoped models (automatic django-tenants filtering)
class ResourceViewSet(TenantFilteredQuerySetMixin, ModelViewSet):
    queryset = Resource.objects.all()
    deny_staff_queryset = True  # Optional: also filter staff at queryset level

    def filter_queryset_for_tenant(self, queryset):
        # Override for custom filtering
        return queryset.filter(is_active=True)

# For User model (shared schema, needs explicit tenant filter)
class CustomerViewSet(UserTenantFilteredMixin, ModelViewSet):
    queryset = User.objects.filter(role=User.Role.CUSTOMER)

Feature Permission Mixins

from core.mixins import PluginFeatureRequiredMixin, TaskFeatureRequiredMixin

# Checks can_use_plugins feature on list/retrieve/create
class PluginViewSet(PluginFeatureRequiredMixin, ModelViewSet):
    pass

# Checks both can_use_plugins AND can_use_tasks
class ScheduledTaskViewSet(TaskFeatureRequiredMixin, TenantFilteredQuerySetMixin, ModelViewSet):
    pass

Base API Views (for non-ViewSet views)

from rest_framework.views import APIView
from core.mixins import TenantAPIView, TenantRequiredAPIView

# Optional tenant - use self.get_tenant()
class MyView(TenantAPIView, APIView):
    def get(self, request):
        tenant = self.get_tenant()  # May be None
        return self.success_response({'data': 'value'})
        # or: return self.error_response('Something went wrong', status_code=400)

# Required tenant - self.tenant always available
class MyTenantView(TenantRequiredAPIView, APIView):
    def get(self, request):
        # self.tenant is guaranteed to exist (returns 400 if missing)
        return Response({'name': self.tenant.name})

Helper Methods Available

Method	Description
self.get_tenant()	Get tenant from request (may be None)
self.get_tenant_or_error()	Returns (tenant, error_response) tuple
self.error_response(msg, status_code)	Standard error response
self.success_response(data, status_code)	Standard success response
self.check_feature(key, name)	Check feature permission, returns error or None

Common Tasks

After modifying Django models:

cd /home/poduck/Desktop/smoothschedule2/smoothschedule
docker compose -f docker-compose.local.yml exec django python manage.py makemigrations
docker compose -f docker-compose.local.yml exec django python manage.py migrate

After modifying frontend:

Frontend hot-reloads automatically. If issues, restart:

cd /home/poduck/Desktop/smoothschedule2/frontend
npm run dev

Debugging 500 errors:

cd /home/poduck/Desktop/smoothschedule2/smoothschedule
docker compose -f docker-compose.local.yml logs django --tail=100

Testing API directly:

curl -s "http://lvh.me:8000/api/resources/" | jq
