The bug was in field mapping when saving AI-generated templates:
- Changed 'type' to 'template_type' (correct column name)
- Changed 'body_template' to 'body_html' (correct column name)
This fixes the 400 Bad Request validation error:
'notNull Violation: MailTemplate.template_type cannot be null'
Now AI template generation works correctly.
Database Changes:
- Remove UNIQUE constraint from mail_templates.template_type
- Allow multiple templates with same type (e.g., multiple bank templates)
Ollama Service Improvements:
- Add detailed logging for AI responses (first 500 chars)
- Check multiple field name variations (subject/Subject/konu/title, body/Body/html/content)
- Improve error messages with actual field names
- Better JSON parsing with fallback
- Clearer prompt instructions to AI
This fixes:
- 400 Validation Error when creating templates with existing type
- AI response parsing issues with different field names
- Auto-save settings before testing connection
- Make model list clickable for easy selection
- Models auto-populate when clicked
- Better user experience for Ollama configuration
Now users can click on a model from the list to select it instantly.

→ AI generates professional phishing test mail in seconds!
- testConnection now sends a real test email to the configured Gmail address
- User receives actual email confirmation that setup works
- Email contains success message and system info
- Google provides App Password with spaces (e.g. 'abcd efgh ijkl mnop')
- Backend now automatically removes all spaces before saving
- Users can paste password directly from Google without manual cleanup
- Also trim gmail_user for safety
- Changed gmail_password to gmail_app_password in request body destructuring
- Matches frontend Settings.jsx which sends gmail_app_password
- Backend still stores as 'gmail_password' key in database (for backward compatibility)
- Fixed handleSave to use separate /gmail and /telegram endpoints
- Changed /test-mail to /test-gmail endpoint
- Added proper null checks in loadSettings to prevent uncontrolled input warnings
- Settings now properly saved to backend with correct endpoint structure
- Updated templateService to return response.data like other services
- Added fallback to empty array in Templates.jsx to prevent map errors
- Ensures consistency across all service modules
