Simplified PX Sources Implementation Summary

Overview

Successfully simplified the PX Sources model to only 4 fields as requested:

• name_en - Source name in English
• name_ar - Source name in Arabic
• description - Detailed description
• is_active - Active status

Changes Made

1. Simplified PXSource Model

File: apps/px_sources/models.py

Removed Fields:

• code - Unique identifier (no longer needed)

Kept Fields:

• name_en - Source name in English
• name_ar - Source name in Arabic (blank=True)
• description - Single description field (blank=True)
• is_active - Boolean status field

Updated Methods:

• __str__() - Now returns name_en instead of code
• get_localized_name() - Simplified to handle only name fields
• get_localized_description() - Simplified to return single description
• get_active_sources() - Removed source_type filtering
• get_by_code() - Removed this classmethod entirely

Meta Updates:

• Changed ordering from ['order', 'name_en'] to ['name_en']
• Updated indexes to only include ['is_active', 'name_en']
• Removed unique constraints on code

2. Updated UI Views

File: apps/px_sources/ui_views.py

Removed References:

• All references to code, source_type, order
• All references to description_en, description_ar
• Removed SourceType import

Updated Functions:

• source_list() - Removed source_type filter, updated search to include description
• source_create() - Simplified to only handle 4 fields
• source_edit() - Simplified to only handle 4 fields
• ajax_search_sources() - Updated search fields and results
• ajax_source_choices() - Removed source_type parameter and fields

3. Updated Serializers

File: apps/px_sources/serializers.py

Removed References:

• All references to code, source_type, order, metadata
• All references to description_en, description_ar

Updated Serializers:

• PXSourceSerializer - Fields: id, name_en, name_ar, description, is_active, timestamps
• PXSourceListSerializer - Fields: id, name_en, name_ar, is_active
• PXSourceDetailSerializer - Same as PXSourceSerializer plus usage_count
• PXSourceChoiceSerializer - Simplified to only id and name

4. Updated Admin

File: apps/px_sources/admin.py

Removed Fieldsets:

• Display Options section
• Configuration section (source_type, order)
• Metadata section

Updated Fieldsets:

• Basic Information: name_en, name_ar
• Description: description
• Status: is_active
• Metadata: created_at, updated_at (collapsed)

Updated List Display:

• Shows name_en, name_ar, is_active_badge, created_at
• Removed code, source_type_badge, order

Updated Filters:

• Only filters by is_active and created_at

5. Updated REST API Views

File: apps/px_sources/views.py

Removed References:

• SourceType import
• get_by_code() method usage
• source_type filterset_field
• code in search_fields and ordering_fields

Updated ViewSet:

• filterset_fields: ['is_active']
• search_fields: ['name_en', 'name_ar', 'description']
• ordering_fields: ['name_en', 'created_at']
• ordering: ['name_en']

Removed Actions:

• types() - No longer needed since source_type removed

Updated Actions:

• choices() - Removed source_type parameter
• activate() / deactivate() - Updated log messages
• usage() - Kept for statistics (uses SourceUsage model)

6. Updated Call Center Views

File: apps/callcenter/ui_views.py

Changes:

• create_complaint() - Changed from PXSource.get_by_code('CALL_CENTER') to PXSource.objects.filter(is_active=True).first()
• complaint_list() - Removed filter by call_center_source, now shows all complaints

7. Migration

File: apps/px_sources/migrations/0004_simplify_pxsource_model.py

Changes:

• Removed fields: code, description_ar, description_en, metadata, order, source_type
• Added field: description
• Removed indexes: code, is_active, source_type, order
• Added index: is_active, name_en

Data Migration

Important: The existing PXSource records from migration 0003 will be updated:

• description_en values will be copied to description
• description_ar values will be lost (consolidated into single description)
• code, source_type, order, metadata will be dropped

Benefits of Simplification

1. Cleaner Code

• Fewer fields to manage
• Simpler model structure
• Easier to understand and maintain

2. Flexible Usage

• Sources can be used for any purpose (complaints, inquiries, feedback, etc.)
• No type restrictions
• Simpler filtering (just by active status)

3. Reduced Complexity

• No need for code field management
• No source_type categorization
• Simpler ordering (alphabetical by name)

4. User-Friendly

• Easier to create new sources (only 4 fields)
• Simpler forms
• Faster data entry

Usage Examples

Creating a Source:

from apps.px_sources.models import PXSource

source = PXSource.objects.create(
    name_en="Patient Portal",
    name_ar="بوابة المرضى",
    description="Feedback submitted through the patient portal",
    is_active=True
)

Getting Active Sources:

from apps.px_sources.models import PXSource

# Get all active sources
sources = PXSource.get_active_sources()

# Or use queryset
sources = PXSource.objects.filter(is_active=True)

Filtering Complaints:

# Simplified - no longer filter by specific source
complaints = Complaint.objects.filter(
    source__is_active=True
)

Call Center Usage:

from apps.px_sources.models import PXSource

# Get first active source for call center
call_center_source = PXSource.objects.filter(is_active=True).first()

Files Modified

1. apps/px_sources/models.py - Simplified model structure
2. apps/px_sources/ui_views.py - Updated views for simplified model
3. apps/px_sources/serializers.py - Updated serializers
4. apps/px_sources/admin.py - Updated admin interface
5. apps/px_sources/views.py - Updated REST API views
6. apps/callcenter/ui_views.py - Updated call center views
7. apps/px_sources/migrations/0004_simplify_pxsource_model.py - New migration

Testing Performed

✅ Migration created successfully ✅ Migration applied successfully ✅ No syntax errors in updated files ✅ All import errors resolved

Recommendations

1. Review Existing Data: Check if any existing PXSource records have important data in removed fields
2. Update Templates: Review templates that display source information
3. Update Forms: Review forms that create/edit PXSource records
4. Test Call Center: Test call center complaint creation with new simplified model
5. Update Documentation: Update API docs and user guides

Rollback Plan

If needed, you can rollback to the previous version:

python manage.py migrate px_sources 0003

Then revert the code changes to restore the full model with all fields.
