# Provider Lead Visibility Fix

## Problem Summary

User `temrentravel` logged in as a provider but could not see any leads in the provider dashboard, despite:
- Having the correct role (`provider`) in the database
- Being listed as active in the admin providers page
- Having proper provider service configuration with destinations and activity categories

## Root Cause Analysis

### Issue 1: Case-Sensitive Activity Category Matching (CRITICAL)

**Location**: `src/db/api.ts` - `providerLeadsApi.getAvailable()` function (lines 1145-1154)

**Problem**: 
The lead filtering logic was performing case-sensitive comparison between:
- Provider's activity_categories: `["müze", "aktivite", "doğal alan", ...]` (lowercase)
- Lead's interests: `["Müze", "Aktivite", "Doğal Alan", ...]` (Title Case)

**Code Before**:
```typescript
filteredLeads = leads.filter(lead => {
  if (!lead.interests || lead.interests.length === 0) return false;
  return lead.interests.some((interest: string) => 
    providerService.activity_categories.includes(interest)  // ❌ Case-sensitive
  );
});
```

**Result**: All leads were filtered out because `"Müze" !== "müze"`, causing the provider dashboard to show zero leads.

### Issue 2: Empty Role Display in Admin Users Page (UI Issue)

**Location**: `src/pages/admin/Users.tsx` (line 191)

**Problem**: 
The `SelectValue` component was empty, not displaying the current role value properly in the admin users table.

**Code Before**:
```tsx
<SelectTrigger className="w-32">
  <SelectValue />  {/* ❌ Empty, not showing current value */}
</SelectTrigger>
```

## Solutions Implemented

### Fix 1: Case-Insensitive Activity Category Matching

**File**: `src/db/api.ts`

**Changes**:
```typescript
// Filter by activity categories (interests array overlap) - case insensitive
let filteredLeads = leads;
if (providerService.activity_categories && providerService.activity_categories.length > 0) {
  // Normalize provider categories to lowercase for comparison
  const normalizedCategories = providerService.activity_categories.map((cat: string) => 
    cat.toLowerCase().trim()
  );
  
  filteredLeads = leads.filter(lead => {
    if (!lead.interests || lead.interests.length === 0) return false;
    // Check if any lead interest matches any provider category (case insensitive)
    return lead.interests.some((interest: string) => 
      normalizedCategories.includes(interest.toLowerCase().trim())
    );
  });
}
```

**Benefits**:
- ✅ Case-insensitive comparison
- ✅ Trims whitespace for robust matching
- ✅ Handles Turkish characters correctly
- ✅ Provider now sees all matching leads

### Fix 2: Proper Role Display in Admin Users Page

**File**: `src/pages/admin/Users.tsx`

**Changes**:
```tsx
<SelectTrigger className="w-32">
  <SelectValue placeholder="Rol seçin">
    {user.role === 'admin' && (
      <div className="flex items-center gap-2">
        <Shield className="h-4 w-4" />
        <span>Admin</span>
      </div>
    )}
    {user.role === 'provider' && (
      <div className="flex items-center gap-2">
        <Briefcase className="h-4 w-4" />
        <span>Provider</span>
      </div>
    )}
    {(!user.role || user.role === 'user') && (
      <div className="flex items-center gap-2">
        <User className="h-4 w-4" />
        <span>Kullanıcı</span>
      </div>
    )}
  </SelectValue>
</SelectTrigger>
```

**Benefits**:
- ✅ Displays current role with icon
- ✅ Shows "Provider" for provider users
- ✅ Shows "Admin" for admin users
- ✅ Shows "Kullanıcı" for regular users
- ✅ Handles null/undefined roles gracefully

## Verification

### Database Verification
```sql
-- Confirmed temrentravel has correct role
SELECT id, username, role FROM profiles WHERE username = 'temrentravel';
-- Result: role = 'provider' ✅

-- Confirmed provider service configuration exists
SELECT provider_id, business_name, destinations, activity_categories 
FROM provider_services 
WHERE provider_id = '43595be4-acce-4d42-bfbf-66cbf204457c';
-- Result: Temren Travel with destinations and categories ✅

-- Confirmed leads exist with matching criteria
SELECT id, destination, interests, status, consent_given 
FROM leads 
WHERE status = 'new' AND consent_given = true;
-- Result: 4 leads with "Kapadokya, Türkiye" destination ✅
```

### Expected Behavior After Fix

1. **Provider Dashboard**:
   - ✅ temrentravel can now see leads matching their destinations
   - ✅ Leads are filtered by activity categories (case-insensitive)
   - ✅ Available leads show in the "Available Leads" tab
   - ✅ Contact information is properly blurred until purchased

2. **Admin Users Page**:
   - ✅ Role column displays "Provider" with briefcase icon for temrentravel
   - ✅ Role dropdown shows current selection
   - ✅ Admin can change roles if needed

## Testing Recommendations

1. **Login as temrentravel**:
   - Navigate to Provider Dashboard
   - Verify leads are visible in "Available Leads" tab
   - Check that leads match provider's destinations (Kapadokya, İstanbul, etc.)
   - Verify activity category filtering works

2. **Admin Panel Check**:
   - Go to Admin → Users
   - Find temrentravel user
   - Verify "Provider" role is displayed correctly
   - Test role dropdown functionality

3. **Lead Filtering Test**:
   - Create a test lead with destination "Kapadokya, Türkiye"
   - Add interests like "Müze", "Aktivite", "Doğal Alan"
   - Verify it appears in temrentravel's dashboard

## Notes

- The role was correctly set in the database from the beginning
- The main issue was the case-sensitive comparison in lead filtering
- Turkish character handling is important for this application
- Always use case-insensitive comparisons for user-generated content matching
