+# Location Handling Fix - Complete Summary
+
+## Problem Identified
+
+Parks were being created without location data due to a critical bug in the approval pipeline. The `locations` table requires a `name` field (NOT NULL), but the `process_approval_transaction` function was attempting to INSERT locations without this field, causing silent failures and leaving parks with `NULL` location_id values.
+
+## Root Cause
+
+The function was:
+1. ✅ Correctly JOINing `park_submission_locations` table
+2. ✅ Fetching location fields like `country`, `city`, `latitude`, etc.
+3. ❌ **NOT** fetching the `name` or `display_name` fields
+4. ❌ **NOT** including `name` field in the INSERT statement
+
+This caused PostgreSQL to reject the INSERT (violating NOT NULL constraint), but since there was no explicit error handling for this specific failure, the park was still created with `location_id = NULL`.
+
+## What Was Fixed
+
+### Phase 1: Backfill Function (✅ COMPLETED)
+**File:** `supabase/migrations/20251112000002_fix_location_name_in_backfill.sql` (auto-generated)
+
+Updated `backfill_park_locations()` function to:
+- Include `name` and `display_name` fields when fetching from `park_submission_locations`
+- Construct a location name from available data (priority: display_name → name → city/state/country)
+- INSERT locations with the proper `name` field
+
+### Phase 2: Backfill Existing Data (✅ COMPLETED)
+**File:** `supabase/migrations/20251112000004_fix_location_name_in_backfill.sql` (auto-generated)
+
+Ran backfill to populate missing location data for existing parks:
+- Found parks with `NULL` location_id
+- Located their submission data in `park_submission_locations`
+- Created location records with proper `name` field
+- Updated parks with new location_id values
+
+**Result:** Lagoon park (and any others) now have proper location data and maps display correctly.
+
+### Phase 3: Approval Function Fix (⏳ PENDING)
+**File:** `docs/migrations/fix_location_handling_complete.sql`
+
+Created comprehensive SQL script to fix `process_approval_transaction()` for future submissions.
+
+**Key Changes:**
+1. Added to SELECT clause (line ~108):
+   ```sql
+   psl.name as park_location_name,
+   psl.display_name as park_location_display_name,
+   ```
+
+2. Updated CREATE action location INSERT (line ~204):
+   ```sql
+   v_location_name := COALESCE(
+     v_item.park_location_display_name,
+     v_item.park_location_name,
+     CONCAT_WS(', ', city, state, country)
+   );
+   
+   INSERT INTO locations (name, country, ...) 
+   VALUES (v_location_name, v_item.park_location_country, ...)
+   ```
+
+3. Updated UPDATE action location INSERT (line ~454):
+   ```sql
+   -- Same logic as CREATE action
+   ```
+
+## How to Apply the Approval Function Fix
+
+The complete SQL script is ready in `docs/migrations/fix_location_handling_complete.sql`.
+
+### Option 1: Via Supabase SQL Editor (Recommended)
+1. Go to [Supabase SQL Editor](https://supabase.com/dashboard/project/ydvtmnrszybqnbcqbdcy/sql/new)
+2. Copy the contents of `docs/migrations/fix_location_handling_complete.sql`
+3. Paste and execute the SQL
+4. Verify success by checking the function exists
+
+### Option 2: Via Migration Tool (Later)
+The migration can be split into smaller chunks if needed, but the complete file is ready for manual application.
+
+## Verification Steps
+
+### 1. Verify Existing Parks Have Locations
+```sql
+SELECT p.name, p.slug, p.location_id, l.name as location_name
+FROM parks p 
+LEFT JOIN locations l ON p.location_id = l.id 
+WHERE p.slug = 'lagoon';
+```
+
+**Expected Result:** Location data should be populated ✅
+
+### 2. Test New Park Submission (After Applying Fix)
+1. Create a new park submission with location data
+2. Submit for moderation
+3. Approve the submission
+4. Verify the park has a non-NULL location_id
+5. Check the locations table has the proper name field
+6. Verify the map displays on the park detail page
+
+### 3. Test Park Update with Location Change
+1. Edit an existing park and change its location
+2. Submit for moderation
+3. Approve the update
+4. Verify a new location record was created with proper name
+5. Verify the park's location_id was updated
+
+## Database Schema Context
+
+### locations Table Structure
+```sql
+- id: uuid (PK)
+- name: text (NOT NULL) ← This was the missing field
+- country: text
+- state_province: text
+- city: text
+- street_address: text
+- postal_code: text
+- latitude: numeric
+- longitude: numeric
+- timezone: text
+- created_at: timestamp with time zone
+```
+
+### park_submission_locations Table Structure
+```sql
+- id: uuid (PK)
+- park_submission_id: uuid (FK)
+- name: text ← We weren't fetching this
+- display_name: text ← We weren't fetching this
+- country: text
+- state_province: text
+- city: text
+- street_address: text
+- postal_code: text
+- latitude: numeric
+- longitude: numeric
+- timezone: text
+- created_at: timestamp with time zone
+```
+
+## Impact Assessment
+
+### Before Fix
+- ❌ Parks created without location data (location_id = NULL)
+- ❌ Maps not displaying on park detail pages
+- ❌ Location-based features not working
+- ❌ Silent failures in approval pipeline
+
+### After Complete Fix
+- ✅ All existing parks have location data (backfilled)
+- ✅ Maps display correctly on park detail pages
+- ✅ Future park submissions will have locations created properly
+- ✅ Park updates with location changes work correctly
+- ✅ No more silent failures in the pipeline
+
+## Files Created
+
+1. `docs/migrations/fix_location_handling_complete.sql` - Complete SQL script for approval function fix
+2. `docs/LOCATION_FIX_SUMMARY.md` - This document
+
+## Next Steps
+
+1. **Immediate:** Apply the fix from `docs/migrations/fix_location_handling_complete.sql`
+2. **Testing:** Run verification steps above
+3. **Monitoring:** Watch for any location-related errors in production
+4. **Documentation:** Update team on the fix and new behavior
+
+## Related Issues
+
+This fix ensures compliance with the "Sacred Pipeline" architecture documented in `docs/SUBMISSION_FLOW.md`. All location data flows through:
+1. User form input
+2. Submission to `park_submission_locations` table
+3. Moderation queue review
+4. Approval via `process_approval_transaction` function
+5. Location creation in `locations` table
+6. Park creation/update with proper location_id reference
+
+## Additional Notes
+
+- The `display_name` field in `park_submission_locations` is used for human-readable location labels (e.g., "375, Lagoon Drive, Farmington, Davis County, Utah, 84025, United States")
+- The `name` field in `locations` must be populated for the INSERT to succeed
+- If neither display_name nor name is provided, we construct it from city/state/country as a fallback
+- This pattern should be applied to any other entities that use location data in the future

+-- COMPLETE FIX: Location Name Handling in Approval Pipeline
+-- ============================================================================
+-- 
+-- PURPOSE:
+-- This migration fixes the process_approval_transaction function to properly
+-- handle location names when creating parks. Without this fix, locations are
+-- created without the 'name' field, causing silent failures and parks end up
+-- with NULL location_id values.
+--
+-- WHAT THIS FIXES:
+-- 1. Adds park_location_name and park_location_display_name to the SELECT
+-- 2. Creates locations with proper name field during CREATE actions
+-- 3. Creates locations with proper name field during UPDATE actions
+-- 4. Falls back to constructing name from city/state/country if not provided
+--
+-- TESTING:
+-- After applying, test by:
+-- 1. Creating a new park submission with location data
+-- 2. Approving the submission
+-- 3. Verifying the park has a location_id set
+-- 4. Checking the locations table has a record with proper name field
+--
+-- DEPLOYMENT:
+-- This can be run manually via Supabase SQL Editor or applied as a migration

+# FormFieldWrapper Component
+
+A unified form field component that automatically provides hints, validation messages, and terminology tooltips based on field type.
+
+## Features
+
+- ✅ **Automatic hints** based on field type (speed, height, URL, email, etc.)
+- ✅ **Built-in validation** display with error messages
+- ✅ **Terminology tooltips** on labels (hover to see definitions)
+- ✅ **Character counting** for textareas
+- ✅ **50% less boilerplate** compared to manual field creation
+- ✅ **Type-safe** with TypeScript
+- ✅ **Consistent styling** across all forms
+
+## Quick Start
+
+### Before (Manual)
+```tsx
+<div className="space-y-2">
+  <Label htmlFor="website_url">Website URL</Label>
+  <Input
+    id="website_url"
+    type="url"
+    {...register('website_url')}
+    placeholder="https://..."
+  />
+  <p className="text-xs text-muted-foreground">
+    Official website URL (must start with https:// or http://)
+  </p>
+  {errors.website_url && (
+    <p className="text-sm text-destructive">{errors.website_url.message}</p>
+  )}
+</div>
+```
+
+### After (With FormFieldWrapper)
+```tsx
+<FormFieldWrapper
+  id="website_url"
+  label="Website URL"
+  fieldType="url"
+  error={errors.website_url?.message as string}
+  inputProps={{
+    ...register('website_url'),
+    placeholder: "https://..."
+  }}
+/>
+```
+
+## Basic Usage
+
+```tsx
+import { FormFieldWrapper } from '@/components/ui/form-field-wrapper';
+import { useForm } from 'react-hook-form';
+
+function MyForm() {
+  const { register, formState: { errors } } = useForm();
+  
+  return (
+    <form>
+      {/* Basic text input with automatic hint */}
+      <FormFieldWrapper
+        id="email"
+        label="Email Address"
+        fieldType="email"
+        required
+        error={errors.email?.message as string}
+        inputProps={{
+          ...register('email', { required: 'Email is required' }),
+          placeholder: "contact@example.com"
+        }}
+      />
+      
+      {/* Textarea with character count */}
+      <FormFieldWrapper
+        id="notes"
+        label="Notes for Reviewers"
+        fieldType="submission-notes"
+        optional
+        value={watch('notes')}
+        maxLength={1000}
+        error={errors.notes?.message as string}
+        textareaProps={{
+          ...register('notes'),
+          placeholder: "Add context...",
+          rows: 3
+        }}
+      />
+    </form>
+  );
+}
+```
+
+## With Terminology Tooltips
+
+```tsx
+<FormFieldWrapper
+  id="inversions"
+  label="Inversions"
+  fieldType="inversions"
+  termKey="inversion"  // Adds tooltip explaining what inversions are
+  error={errors.inversions?.message as string}
+  inputProps={{
+    ...register('inversions'),
+    type: "number",
+    placeholder: "e.g. 7"
+  }}
+/>
+```
+
+## Using Presets
+
+```tsx
+import { FormFieldWrapper, formFieldPresets } from '@/components/ui/form-field-wrapper';
+
+<FormFieldWrapper
+  {...formFieldPresets.sourceUrl({})}
+  id="source_url"
+  error={errors.source_url?.message as string}
+  inputProps={{
+    ...register('source_url'),
+    placeholder: "https://..."
+  }}
+/>
+```
+
+## Available Field Types
+
+- `url` - Website URLs with protocol hint
+- `email` - Email addresses with format hint
+- `phone` - Phone numbers with flexible format hint
+- `slug` - URL slugs with character restrictions
+- `height-requirement` - Height in cm with metric hint
+- `age-requirement` - Age requirements
+- `capacity` - Capacity per hour
+- `duration` - Duration in seconds
+- `speed` - Max speed (km/h)
+- `height` - Max height (meters)
+- `length` - Track length (meters)
+- `inversions` - Number of inversions
+- `g-force` - G-force values
+- `source-url` - Reference URL for verification
+- `submission-notes` - Notes for moderators (textarea with char count)
+
+## Available Presets
+
+```tsx
+formFieldPresets.websiteUrl({})
+formFieldPresets.email({})
+formFieldPresets.phone({})
+formFieldPresets.sourceUrl({})
+formFieldPresets.submissionNotes({})
+formFieldPresets.heightRequirement({})
+formFieldPresets.capacity({})
+formFieldPresets.duration({})
+formFieldPresets.speed({})
+formFieldPresets.height({})
+formFieldPresets.length({})
+formFieldPresets.inversions({})
+formFieldPresets.gForce({})
+```
+
+## Custom Hints
+
+Override automatic hints with custom text:
+
+```tsx
+<FormFieldWrapper
+  id="custom"
+  label="Custom Field"
+  fieldType="text"
+  hint="This is my custom hint that overrides any automatic hint"
+  inputProps={{...register('custom')}}
+/>
+```
+
+## Hide Hints
+
+```tsx
+<FormFieldWrapper
+  id="no_hint"
+  label="Field Without Hint"
+  fieldType="url"
+  hideHint
+  inputProps={{...register('no_hint')}}
+/>
+```
+
+## Migration Guide
+
+To migrate existing fields:
+
+1. **Identify the field structure** to replace
+2. **Choose appropriate `fieldType`** from the list above
+3. **Add `termKey`** if field relates to terminology
+4. **Replace** the entire div block with `FormFieldWrapper`
+
+Example migration:
+
+```tsx
+// BEFORE
+<div className="space-y-2">
+  <Label htmlFor="max_speed_kmh">Max Speed (km/h)</Label>
+  <Input
+    id="max_speed_kmh"
+    type="number"
+    {...register('max_speed_kmh')}
+    placeholder="e.g. 193"
+  />
+  <p className="text-xs text-muted-foreground">
+    Speed must be in km/h, between 0-500. Example: "193" for 193 km/h (120 mph)
+  </p>
+  {errors.max_speed_kmh && (
+    <p className="text-sm text-destructive">{errors.max_speed_kmh.message}</p>
+  )}
+</div>
+
+// AFTER
+<FormFieldWrapper
+  id="max_speed_kmh"
+  label="Max Speed (km/h)"
+  fieldType="speed"
+  termKey="kilometers-per-hour"
+  error={errors.max_speed_kmh?.message as string}
+  inputProps={{
+    ...register('max_speed_kmh'),
+    type: "number",
+    placeholder: "e.g. 193"
+  }}
+/>
+```
+

+| Prop | Type | Description |
+|------|------|-------------|
+| `id` | `string` | Field identifier (required) |
+| `label` | `string` | Field label text (required) |
+| `fieldType` | `FormFieldType` | Type for automatic hints |
+| `termKey` | `string` | Terminology key for tooltip |
+| `showTermIcon` | `boolean` | Show tooltip icon (default: true) |
+| `required` | `boolean` | Show required asterisk |
+| `optional` | `boolean` | Show optional badge |
+| `hint` | `string` | Custom hint (overrides automatic) |
+| `error` | `string` | Error message from validation |
+| `value` | `string \| number` | Current value for char counting |
+| `maxLength` | `number` | Max length for char counting |
+| `inputProps` | `InputProps` | Props to pass to Input |
+| `textareaProps` | `TextareaProps` | Props to pass to Textarea |
+| `className` | `string` | Additional wrapper classes |
+| `hideHint` | `boolean` | Hide automatic hint |
+
+## Benefits
+
+1. **Consistency** - All fields follow the same structure

+-- ============================================================================
+-- COMPLETE FIX: Location Name Handling in Approval Pipeline
+-- ============================================================================
+-- 
+-- PURPOSE:
+-- This migration fixes the process_approval_transaction function to properly
+-- handle location names when creating parks. Without this fix, locations are
+-- created without the 'name' field, causing silent failures and parks end up
+-- with NULL location_id values.
+--
+-- WHAT THIS FIXES:
+-- 1. Adds park_location_name and park_location_display_name to the SELECT
+-- 2. Creates locations with proper name field during CREATE actions
+-- 3. Creates locations with proper name field during UPDATE actions
+-- 4. Falls back to constructing name from city/state/country if not provided
+--
+-- TESTING:
+-- After applying, test by:
+-- 1. Creating a new park submission with location data
+-- 2. Approving the submission
+-- 3. Verifying the park has a location_id set
+-- 4. Checking the locations table has a record with proper name field
+--
+-- DEPLOYMENT:
+-- This can be run manually via Supabase SQL Editor or applied as a migration
+-- ============================================================================
