# Policy API Setup - Complete Guide

## 🎉 Summary

Successfully created a comprehensive Policy Management System with:
- **3 Policy Types**: Privacy Policy, Terms of Use, Support Policy
- **Professional Enterprise Content**: 13-15 sections per policy with detailed legal and operational information
- **Full CRUD API**: RESTful API endpoints for managing policies
- **Dynamic Frontend**: React-based policy viewer with loading states and error handling

---

## 📋 What Was Created

### Backend (Django)

#### 1. **Models** (`backend/policies/models.py`)
- `Policy`: Main policy document with metadata (type, title, version, effective date)
- `PolicySection`: Individual sections within each policy

#### 2. **API Views** (`backend/policies/views.py`)
- `PolicyViewSet`: RESTful viewset for policy CRUD operations
- Endpoints support filtering by type
- Retrieve by ID or policy type

#### 3. **Serializers** (`backend/policies/serializers.py`)
- `PolicySerializer`: Full policy with all sections
- `PolicyListSerializer`: Simplified list view
- `PolicySectionSerializer`: Individual section data

#### 4. **Admin Interface** (`backend/policies/admin.py`)
- Full admin panel integration
- Inline section editing
- List filters and search functionality

#### 5. **Management Command** (`backend/policies/management/commands/populate_policies.py`)
- Command: `python manage.py populate_policies`
- Creates/updates all 3 policies with professional content
- 42 total sections across all policies

### Frontend (Next.js)

#### 1. **API Service** (`lib/api/policyService.ts`)
- `getPolicies()`: Fetch all policies
- `getPolicyByType(type)`: Fetch specific policy
- `getPolicyById(id)`: Fetch by ID

#### 2. **React Hook** (`lib/hooks/usePolicy.ts`)
- `usePolicies()`: Hook for all policies
- `usePolicy(type)`: Hook for specific policy
- `usePolicyById(id)`: Hook for policy by ID

#### 3. **Policy Page** (`app/policy/page.tsx`)
- Dynamic page showing policy content
- Query parameter: `?type=privacy|terms|support`
- Loading and error states
- Responsive design
- Styled with inline styles

#### 4. **Support Center Integration** (`components/pages/support/SupportCenterHero.tsx`)
- Added 3 new clickable cards:
  - Privacy Policy → `/policy?type=privacy`
  - Terms of Use → `/policy?type=terms`
  - Support Policy → `/policy?type=support`

## 🎨 Frontend Usage

### 1. **Direct Navigation**
```typescript
// Link to policies from anywhere
<a href="/policy?type=privacy">Privacy Policy</a>
<a href="/policy?type=terms">Terms of Use</a>
<a href="/policy?type=support">Support Policy</a>
```

### 2. **Using the Hook**
```typescript
import { usePolicy } from '@/lib/hooks/usePolicy';

function MyComponent() {
  const { data: policy, isLoading, error } = usePolicy('privacy');
  
  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;
  
  return (
    <div>
      <h1>{policy.title}</h1>
      {policy.sections.map(section => (
        <div key={section.id}>
          <h2>{section.heading}</h2>
          <p>{section.content}</p>
        </div>
      ))}
    </div>
  );
}
```
