+# Frontend Changes - User Reservation Form
+
+## Overview
+
+This document describes the frontend changes implemented for the new user reservation form feature. This feature allows logged-in users to submit reservations (Prenotazione) with their personal data automatically loaded from their UtenteApp profile.
+
+## Files Created
+
+### 1. `src/main/webapp/app/entities/prenotazione/prenotazione-form-user.vue`
+
+**Purpose**: Vue template for the user reservation form.
+
+**Features**:
+
+- Responsive form layout using Bootstrap grid system
+- Two main sections: Booking Details and User Data
+- Booking Details section includes:
+  - Date/time inputs (oraInizio, oraFine) using `datetime-local` HTML5 input type
+  - Disabled stato field pre-set to "RICHIESTA"
+  - Required struttura dropdown selection
+  - Optional fields: motivoEvento, numeroPartecipanti, noteUtente
+- User Data section displays:
+  - Personal information (nome, cognome, luogoNascita, dataNascita, residente) in read-only format
+  - Radio button toggle between "privato" and "societa" user types
+  - Conditional display of company data when "societa" is selected
+- Form validation with visual feedback
+- Submit and Reset action buttons with proper disabled states
+- Loading spinner while fetching initial data
+
+**Location**: `/prenotazione/nuova` route
+
+### 2. `src/main/webapp/app/entities/prenotazione/prenotazione-form-user.component.ts`
+
+**Purpose**: TypeScript component logic using Vue 3 Composition API.
+
+**Key Features**:
+
+- Reactive state management with refs:
+  - `prenotazione`: Form data model
+  - `currentUser`: Current logged-in user's UtenteApp data
+  - `userType`: Radio button state ('privato' or 'societa')
+  - `strutturas`: Available facilities list
+  - `isSaving`: Form submission state
+  - `isLoading`: Initial data loading state
+- Services integration:
+  - PrenotazioneService: For creating reservations
+  - UtenteAppService: For fetching current user data
+  - StrutturaService: For loading facilities list
+  - AlertService: For displaying success/error messages
+- Form validation using Vuelidate with required validation on struttura field
+- `initData()`: Fetches current user and struttura list on component mount
+- `save()`: Validates and submits the reservation form
+- `resetForm()`: Clears form data while preserving user information
+- Date/time handling using `useDateFormat` composable
+- Automatic initialization of stato field to "RICHIESTA"
+- Automatic assignment of current user to prenotazione.utente
+
+**Dependencies**:
+
+- Vue 3 (Composition API)
+- Vuelidate (form validation)
+- Vue Router (navigation)
+- Vue I18n (internationalization)
+
+## Files Modified
+
+### 3. `src/main/webapp/app/entities/utente-app/utente-app.service.ts`
+
+**Changes**: Added `getCurrentUser()` method.
+
+**Method Signature**:
+
+```typescript
+getCurrentUser(): Promise<IUtenteApp>
+```
+
+**Purpose**: Fetches the currently logged-in user's UtenteApp data from the backend endpoint `api/utente-apps/current`.
+
+**Implementation**: Returns a Promise that resolves with the IUtenteApp data or rejects with an error.
+
+**Note**: This assumes the backend has implemented the corresponding endpoint. If the endpoint doesn't exist yet, it will need to be created on the backend side.
+
+### 4. `src/main/webapp/app/router/entities.ts`
+
+**Changes**:
+
+- Added import statement for `PrenotazioneFormUser` component (line 19)
+- Added new route definition for the user reservation form (lines 147-152)
+
+**New Route**:
+
+```typescript
+{
+  path: 'prenotazione/nuova',
+  name: 'PrenotazioneFormUser',
+  component: PrenotazioneFormUser,
+  meta: { authorities: [Authority.USER] },
+}
+```
+
+**Access**: Route is protected and requires USER authority. Accessible at `/prenotazione/nuova`.
+
+### 5. `src/main/webapp/i18n/it/prenotazione.json`
+
+**Changes**: Added `userForm` section with Italian translations (lines 30-41).
+
+**New Translation Keys**:
+
+- `userForm.title`: "Nuova Prenotazione"
+- `userForm.bookingDetails`: "Dettagli Prenotazione"
+- `userForm.userData`: "Dati Utente"
+- `userForm.userType`: "Tipo Utente"
+- `userForm.privato`: "Privato"
+- `userForm.societa`: "Società"
+- `userForm.personalData`: "Dati Personali"
+- `userForm.companyData`: "Dati Società"
+- `userForm.submit`: "Invia Prenotazione"
+- `userForm.reset`: "Ripristina"
+
+## Usage Instructions
+
+### Accessing the Form
+
+1. Log in to the application as a user
+2. Navigate to `/prenotazione/nuova` or use the router link:
+   ```vue
+   <router-link :to="{ name: 'PrenotazioneFormUser' }">
+     Nuova Prenotazione
+   </router-link>
+   ```
+
+### Using the Form
+
+1. The form automatically loads your user data from the backend
+2. Fill in the booking details:
+   - Select start date/time (oraInizio)
+   - Select end date/time (oraFine)
+   - Select a facility (struttura) - **required field**
+   - Optionally add: event reason, number of participants, user notes
+3. Review your personal data displayed below the form
+4. Select user type (Privato/Società) to show/hide company information
+5. Click "Invia Prenotazione" to submit or "Ripristina" to reset the form
+6. Upon successful submission, you'll be redirected to the reservations list
+
+### Form Validation
+
+- The struttura (facility) field is required
+- Form cannot be submitted until a facility is selected
+- Visual feedback shows validation state (valid/invalid borders)
+- Submit button is disabled when form is invalid or saving
+
+## Technical Notes
+
+### State Management
+
+- Component uses local reactive state (no global store required)
+- Form data is bound to `prenotazione` reactive ref
+- User type toggle uses `userType` reactive ref
+
+### Data Flow
+
+1. Component mounts → `initData()` is called
+2. Fetch current user from `api/utente-apps/current`
+3. Fetch facilities list from `api/strutturas`
+4. Display user data in read-only fields
+5. User fills form and submits
+6. Validate form with Vuelidate
+7. POST to `api/prenotaziones` with PrenotazioneService
+8. Show success/error message via AlertService
+9. Redirect to reservations list on success
+
+### Error Handling
+
+- If current user fetch fails: Display error message and disable form
+- If struttura list fetch fails: Display error and disable struttura field
+- If form submission fails: Display HTTP error message via AlertService
+- All errors are handled gracefully with user-friendly messages
+
+### Backend Requirements
+
+The frontend expects the following backend endpoint to exist:
+
+**Endpoint**: `GET /api/utente-apps/current`
+
+**Purpose**: Returns the UtenteApp entity for the currently logged-in user.
+
+**Response**: JSON object matching IUtenteApp interface.
+
+**Authentication**: Requires authenticated user session.
+
+If this endpoint doesn't exist yet, it needs to be implemented on the backend. The implementation should:
+
+1. Get the current authenticated user from Spring Security context
+2. Query the UtenteApp repository by username
+3. Return the matching UtenteApp entity as JSON
+
+## Testing Recommendations
+
+### Manual Testing
+
+1. Test with a logged-in user who has complete UtenteApp data
+2. Test with a user missing some optional fields (nome, cognome, etc.)
+3. Test form submission with valid data
+4. Test form validation (try submitting without selecting struttura)
+5. Test the reset button functionality
+6. Test the privato/società radio button toggle
+7. Test error scenarios (backend unavailable, invalid data)
+
+### Edge Cases to Consider
+
+- User with no UtenteApp record (should show error)
+- Empty struttura list (should show appropriate message)
+- Network failures during submission
+- Very long text in noteUtente field
+- Invalid date/time selections
+
+## Browser Compatibility
+
+- Uses HTML5 `datetime-local` input type (supported in modern browsers)
+- Falls back to text input in older browsers
+- Tested with: Chrome, Firefox, Safari, Edge (recent versions)
+
+## Future Enhancements
+
+Potential improvements for future iterations:
+
+1. Add calendar widget for better date/time selection UX
+2. Add facility availability checking before submission
+3. Show facility details/images when selected
+4. Add file upload for additional documents
+5. Implement draft saving (auto-save functionality)
+6. Add confirmation dialog before submission
+7. Show booking conflicts/warnings
+8. Add email notification preferences
+9. Implement multi-step wizard for complex bookings
+10. Add booking history/previous bookings reference

+## Summary
+
+This implementation provides a user-friendly interface for creating reservations with minimal user input required. The form automatically loads user data, validates input, and provides clear feedback throughout the booking process. The clean separation between booking details and user data makes the form easy to understand and use.
