The code block displaying the "Result-PDF" success message was removed from its original location and reintroduced in a different section of the `Upload.cshtml` file. The new placement is after the success message confirming that the invoice was saved in the database. The functionality and alert structure remain unchanged, displaying the file path of the generated PDF if `Model.ResultFilePath` is not empty.
Added a warning message in `Upload.cshtml` to notify users when a duplicate invoice is detected. Introduced the `IsDuplicate` property in `UploadModel` to track duplicates and updated the `OnPostAsync` method to set this property based on the `ImportedAt` timestamp.
Enhanced the `ImportAsync` method in `ZugferdImportService` to include duplicate detection by checking the database for invoices with the same `InvoiceNumber` and `SellerTaxId`. If a duplicate is found, it logs a warning and returns the existing invoice.
Updated `ImportAsync` to accept an optional `guidelineId` parameter and added logging for duplicate detection and successful imports.
Added a new `GuidelineId` property to the `ZugferdInvoice` model to store the ZUGFeRD Guideline ID extracted from XMP metadata. Updated the `AppDbContextModelSnapshot.cs` to reflect this change and created a migration (`20260527133241_AddGuidelineId`) to add the `GuidelineId` column to the `ZugferdInvoices` table.
Generated the corresponding designer file for the migration to define the updated database schema. Minor formatting changes were made to `ZugferdInvoice.cs` without functional impact.
Introduced the `ResultFilePath` property in the `ZugferdInvoice` model to store the path of generated result PDFs. Added a new service, `PdfResultPackageService`, to create result PDFs by converting the original PDF to PDF/A-3b format and attaching a report file. Updated `Upload.cshtml` and `Upload.cshtml.cs` to handle and display the `ResultFilePath`.
Created a migration to add the `ResultFilePath` column to the database. Updated `Program.cs` to register the new service and added configuration sections in `appsettings.json` for input and output directories. Enhanced error handling and logging for better traceability.
Enhanced `PdfExtractionResult` with a new `ZugferdGuidelineId` property to store the ZUGFeRD Guideline-ID extracted from XMP metadata. Updated `Upload.cshtml` to display this information in the UI if available.
Implemented ZUGFeRD Guideline-ID extraction in `PdfAttachmentExtractorService` using a new helper method `ExtractGuidelineId`, which parses XMP metadata for known prefixes. Added logging for extracted Guideline-IDs and improved error handling with a `try-catch` block for metadata processing.
Fixed `FileAttachments` handling in `PdfAttachmentExtractorService` by converting to `List<T>` for proper `Count` property usage.
Previously, the method directly converted a byte array to a string
without accounting for a potential UTF-8 Byte Order Mark (BOM).
This commit introduces logic to remove the BOM (if present)
using `TrimStart('\uFEFF')` after converting the byte array
to a string.
Additionally, a comment was added to clarify the purpose of
this change.
Added `PdfALevel` and `PdfAWarning` properties to the `PdfExtractionResult` class to store the PDF/A compliance level and indicate if a warning should be displayed for non-compliance.
Updated `Upload.cshtml` to display the PDF/A compliance level and conditionally show a warning message if the document is not PDF/A compliant.
Enhanced `PdfAttachmentExtractorService` to determine the PDF/A compliance level using `PdfDocumentProcessor`, map it to a string representation, and log the compliance level. Added logic to set `PdfAWarning` for non-compliant documents.
Added new navigation menu items in `_Layout.cshtml` for "Rechnungen" (Invoices) and "PDF hochladen" (Upload PDF) with icons, paths, and selection logic.
Created a new Razor Page `Index.cshtml` to display imported invoices using a `DataGrid` with features like filtering, paging, and column formatting. Added a conditional message for when no invoices are available.
Implemented the `IndexModel` class in `Index.cshtml.cs` to handle backend logic, including fetching and sorting invoices from the database using `AppDbContext`.
Enhanced `ZugferdInvoice` model with default string values to prevent nulls. Updated `Upload.cshtml` to display parsed invoice data.
Refactored `Upload.cshtml.cs` to handle ZUGFeRD XML parsing and database storage. Introduced `ImportedInvoice` property and buffered file processing with `MemoryStream`.
Extended `ZugferdParserService` to support ZUGFeRD v1, v1.0 FeRD, and v2/Factur-X. Added version-specific parsing methods and namespaces. Improved date and decimal parsing for robustness.
Added database migration (`20260522084606_InitialCreate`) to define `ZugferdInvoices` table. Updated migration snapshot to reflect schema changes.
Fixed localization issue in `Upload.cshtml.cs` error message.
The `ConnectionStrings` section in the `appsettings.json` file was updated. The `EcmContext` connection string, previously an empty string, was replaced with a connection string pointing to a SQL Server instance.
The new connection string includes the server name, database name, user ID, password, and a flag to trust the server certificate. This change enables the application to connect to the specified SQL Server database.
