# Survey Form AttributeError Fix

## Problem
When accessing `/surveys/send/`, the application threw an `AttributeError: 'User' object has no attribute 'get'`.

### Error Details
```
AttributeError at /surveys/send/
'User' object has no attribute 'get'
Request Method: GET
Request URL: http://localhost:8000/surveys/send/
Exception Location: /home/ismail/projects/HH/.venv/lib/python3.12/site-packages/django/utils/functional.py, line 253, in inner
Raised during: apps.surveys.ui_views.manual_survey_send
```

The error occurred during template rendering at line 93 of `templates/surveys/manual_send.html`.

## Root Cause
The forms `ManualSurveySendForm`, `ManualPhoneSurveySendForm`, and `BulkCSVSurveySendForm` were being instantiated with a `user` parameter in the view:

```python
form = ManualSurveySendForm(user)  # In manual_survey_send view
form = ManualPhoneSurveySendForm(user)  # In manual_survey_send_phone view
form = BulkCSVSurveySendForm(user)  # In manual_survey_send_csv view
```

However, these forms did not have custom `__init__` methods to accept the `user` parameter. When Django tried to pass the user object as the first positional argument, the form's default `__init__` method expected a dictionary-like object (data) but received a User object instead.

## Solution
Added custom `__init__` methods to all three forms that:
1. Accept a `user` parameter as the first argument
2. Call the parent class's `__init__` method correctly
3. Store the user object for potential later use
4. Filter the `survey_template` queryset to show only templates from the user's hospital

### Changes Made to `apps/surveys/forms.py`

#### 1. ManualSurveySendForm
```python
class ManualSurveySendForm(forms.Form):
    """Form for manually sending surveys to patients or staff"""
    
    def __init__(self, user, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.user = user
        # Filter survey templates by user's hospital
        if user.hospital:
            self.fields['survey_template'].queryset = SurveyTemplate.objects.filter(
                hospital=user.hospital,
                is_active=True
            )
    
    # ... rest of the form fields
```

#### 2. ManualPhoneSurveySendForm
```python
class ManualPhoneSurveySendForm(forms.Form):
    """Form for sending surveys to a manually entered phone number"""
    
    def __init__(self, user, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.user = user
        # Filter survey templates by user's hospital
        if user.hospital:
            self.fields['survey_template'].queryset = SurveyTemplate.objects.filter(
                hospital=user.hospital,
                is_active=True
            )
    
    # ... rest of the form fields
```

#### 3. BulkCSVSurveySendForm
```python
class BulkCSVSurveySendForm(forms.Form):
    """Form for bulk sending surveys via CSV upload"""
    
    def __init__(self, user, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.user = user
        # Filter survey templates by user's hospital
        if user.hospital:
            self.fields['survey_template'].queryset = SurveyTemplate.objects.filter(
                hospital=user.hospital,
                is_active=True
            )
    
    # ... rest of the form fields
```

Note: `BulkCSVSurveySendForm` already had an `__init__` method but it was defined after the field definition, which could cause issues. It's been moved before the field definitions for consistency.

## Benefits
1. **Fixes the AttributeError**: Forms can now be instantiated with a user parameter
2. **Improved Security**: Survey templates are filtered by the user's hospital, preventing users from seeing templates they shouldn't have access to
3. **Better User Experience**: Users only see relevant survey templates in the dropdown
4. **Consistency**: All three manual survey send forms now have the same initialization pattern

## Testing
To verify the fix:
1. Navigate to `/surveys/send/`
2. The page should load without errors
3. The survey template dropdown should only show templates from the user's hospital
4. Test the phone-based survey send at `/surveys/send/phone/`
5. Test the CSV-based bulk send at `/surveys/send/csv/`

All three views should now work correctly.
