# Parks Tests Migration Fixes - Owner → Operator

## Task Overview
Update parks tests to fix field mismatches from the Company.owner → Operator migration.

## Issues Identified

### 1. test_models.py
- **Line 28**: `owner=self.operator` should be `operator=self.operator`
- **Line 50**: Correctly uses `self.park.operator` but creation is wrong

### 2. test_filters.py  
- **Line 58**: `owner=cls.operator2` should be `operator=cls.operator2`
- **Line 206**: Test method name `test_company_filtering` references old concept
- **Lines 206-222**: Filter tests use `has_owner` which should be `has_operator`

### 3. test_search.py
- ✅ No issues - creates parks without operators

## Required Changes

### Field Name Updates
- Change all `owner=` to `operator=` in Park.objects.create()
- Update test assertions from `has_owner` to `has_operator`
- Update filter parameter from `operator` to match new field structure

### Test Method Updates
- Rename `test_company_filtering` to `test_operator_filtering`
- Update comments and docstrings to reflect new terminology

## Entity Relationship Rules Applied
- Parks MUST have an Operator (required relationship)
- Parks MAY have a PropertyOwner (optional, usually same as Operator)
- Parks CANNOT directly reference Company entities

## Files Updated

### ✅ parks/tests/test_models.py
- **Fixed Line 28**: Changed `owner=self.operator` to `operator=self.operator`

### ✅ parks/tests/test_filters.py
- **Fixed Line 58**: Changed `owner=cls.operator2` to `operator=cls.operator2`
- **Fixed Line 193**: Renamed `test_company_filtering` to `test_operator_filtering`
- **Fixed Lines 196-222**: Updated filter tests to use `has_operator` instead of `has_owner`
- **Fixed Lines 196, 201**: Changed `.id` to `.pk` for proper Django model access

### ✅ parks/filters.py
- **Fixed Line 137**: Changed `has_owner` to `has_operator` in filter logic

## Test Results
- ✅ All owner → operator migration issues resolved
- ✅ Filter tests now pass
- ⚠️ One unrelated test failure in ParkArea historical slug lookup (not migration-related)

## Migration Status: COMPLETED
All parks tests have been successfully updated to work with the new operator field and Operator model structure. The entity relationship rules are now properly enforced in the test suite.
