Critical Fields Added to Forms

AppointmentBookingForm (appointments/forms.py)

# Added to Meta.fields:
'finance_cleared',      # BooleanField - visible checkbox

# Added to Meta.widgets:
'finance_cleared': forms.CheckboxInput(attrs={'class': 'form-check-input'}),
'consent_verified': forms.CheckboxInput(attrs={'class': 'form-check-input'}),

InvoiceForm (finance/forms.py)

# Added to Meta.fields:
'invoice_type',  # CharField with choices - ZATCA requirement

Select2 Pattern Applied

Standard Widget Configuration

# For all patient fields:
'patient': forms.Select(attrs={
    'class': 'form-select select2',
    'data-placeholder': 'Select patient'
})

# For all provider fields:
'provider': forms.Select(attrs={
    'class': 'form-select select2',
    'data-placeholder': 'Select provider'
})

# For all clinic fields:
'clinic': forms.Select(attrs={
    'class': 'form-select select2',
    'data-placeholder': 'Select clinic'
})

# For other FK fields:
'field_name': forms.Select(attrs={
    'class': 'form-select select2',
    'data-placeholder': 'Select [field_name]'
})

Views Verification

All views properly use form_class attribute pointing to updated forms:

Appointments

• AppointmentCreateView → AppointmentForm ✅
• AppointmentUpdateView → AppointmentForm ✅
• AppointmentRescheduleView → RescheduleForm ✅

Finance

• InvoiceCreateView → InvoiceForm ✅
• InvoiceUpdateView → InvoiceForm ✅
• PaymentCreateView → PaymentForm ✅
• PackageCreateView → PackageForm ✅
• PackageUpdateView → PackageForm ✅

Other Apps

All other apps follow the same pattern with proper form_class usage.

---

Template Compatibility

Templates Verified:

• ✅ appointments/appointment_form.html - Has own Select2 init, compatible
• ✅ finance/invoice_form.html - Has own Select2 init, compatible
• ✅ ot/consult_form.html - Has own Select2 init, compatible

Template Patterns:

1. Manual field rendering: Templates manually render {{ form.field }} - Select2 class will be applied ✅
2. Crispy forms: Templates use {% crispy form %} - Select2 class will be applied ✅
3. Custom Select2 init: Some templates have their own initialization - Will work alongside global init ✅

---

JavaScript Initialization

Global Initialization (static/js/select2-init.js)

function initSelect2(scope) {
    const $scope = scope ? $(scope) : $(document);
    $scope.find('.select2').each(function() {
        if (!$(this).hasClass('select2-hidden-accessible')) {
            const dir = document.documentElement.getAttribute('dir') === 'rtl' ? 'rtl' : 'ltr';
            $(this).select2({
                width: '100%',
                dir: dir,
                allowClear: true,
                placeholder: $(this).data('placeholder') || '',
                language: dir === 'rtl' ? 'ar' : 'en'
            });
        }
    });
}

Event Listeners:

• DOMContentLoaded - Initial page load
• htmx:afterSwap - After HTMX content swap
• htmx:afterSettle - After HTMX settles
• htmx:beforeSwap - Cleanup before swap

Maintenance Notes

Adding New Forms:

When creating new forms with FK/M2M fields, follow this pattern:

class NewForm(forms.ModelForm):
    class Meta:
        model = YourModel
        fields = ['patient', 'provider', ...]
        widgets = {
            'patient': forms.Select(attrs={
                'class': 'form-select select2',
                'data-placeholder': 'Select patient'
            }),
            'provider': forms.Select(attrs={
                'class': 'form-select select2',
                'data-placeholder': 'Select provider'
            }),
        }

Updating Select2:

To update Select2 version, change CDN links in templates/base.html:

<link href="https://cdn.jsdelivr.net/npm/select2@VERSION/dist/css/select2.min.css" rel="stylesheet" />
<script src="https://cdn.jsdelivr.net/npm/select2@VERSION/dist/js/select2.full.min.js"></script>

Troubleshooting:

• If Select2 doesn't initialize: Check browser console for errors
• If RTL doesn't work: Verify dir attribute on <html> tag
• If HTMX breaks Select2: Check event listeners in select2-init.js
• If double-initialization occurs: Check for duplicate Select2 calls in templates
