Architecture:
- Create companies table with company_code as unique identifier
- Add company_id foreign key to admin_users for multi-tenant support
- Implement backward compatibility with DEFAULT company for existing users
Core Components:
- Company entity with full CRUD operations
- ICompanyRepository interface following Repository pattern
- CompanyRepository with Dapper implementation
- CompanyService with business logic and validation
- CompanyController with REST API endpoints
Admin UI:
- CompanyForm reusable component (Create/Edit pattern)
- CompanyList.razor with pagination and company overview
- CompanyCreate.razor for registering new companies
- CompanyEdit.razor for managing existing companies with delete
- All pages follow admin-page-hero pattern for consistency
SOLID Principles:
- Single Responsibility: Each component has one reason to change
- Open/Closed: Extensible without modifying existing code
- Interface Segregation: Clean repository and service contracts
- Dependency Inversion: All layers depend on abstractions
Database Migration (V014):
- Creates companies table with active/inactive status
- Assigns existing admin users to DEFAULT company
- Provides foundation for role-based access control
Future Enhancement:
- Admin users can belong to specific companies
- Data filtering based on company_id (multi-tenant isolation)
- Company-based permission model
Core Components:
- Create reusable InquiryForm.razor component following SOLID principles
- Implement InquiryCreate.razor for registering new inquiries (offline, phone)
- Implement InquiryEdit.razor for modifying existing inquiries with delete
- Add DeleteAsync method to InquiryRepository and InquiryService
- Update InquiryList with 'Create' button and Edit link in table
Architecture:
- InquiryForm: Encapsulates form logic, can be reused for create/edit
- Service Layer: All operations go through InquiryService for cache invalidation
- Repository Pattern: Database operations isolated in InquiryRepository
- UI Consistency: Both pages follow admin-page-hero pattern
Features:
- Admin can create inquiries from phone/offline consultations
- Admin can modify inquiry details (name, phone, email, message, status, memo)
- Admin can delete inquiries with confirmation dialog
- All operations update dashboard cache
- Status validation and error handling throughout
Testing:
- Updated FakeInquiryRepository in tests to implement DeleteAsync
