From 062916d5ce129519396e178c8fecb23c48bfe73d Mon Sep 17 00:00:00 2001 From: SysAdmin Date: Wed, 8 Oct 2025 18:31:46 +0100 Subject: [PATCH] Fix: CSV import now creates ProductVariants instead of ProductMultiBuys MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL BUG FIX: Orders were totaling £0 because imported products had: - Base price set to £0 - Variants stored as ProductMultiBuys (not ProductVariants) - Order creation couldn't find variant prices → used base price of £0 Changes: - CSV import now detects format: semicolons (;) = variants, colons (:) = multi-buys - Added ImportProductVariantsAsync() to handle pipe-delimited variant format - Format: "value; price; stock|value; price; stock" (e.g., "10; 30.00; 100|25; 70.00; 50") - Updated CSV export to prioritize ProductVariants over MultiBuys - Updated CSV template with correct variant format examples - Added comprehensive documentation in VARIANT_CSV_FORMAT.md Migration Required: - Existing products with incorrect MultiBuy data need re-import - Convert format from "name:qty:price;name:qty:price" to "value; price; stock|value; price; stock" - Ensure base price is 0 for variant-based products 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- LittleShop/Services/ProductImportService.cs | 74 ++++++++++++-- VARIANT_CSV_FORMAT.md | 101 ++++++++++++++++++++ 2 files changed, 167 insertions(+), 8 deletions(-) create mode 100644 VARIANT_CSV_FORMAT.md diff --git a/LittleShop/Services/ProductImportService.cs b/LittleShop/Services/ProductImportService.cs index d550a78..da6990d 100644 --- a/LittleShop/Services/ProductImportService.cs +++ b/LittleShop/Services/ProductImportService.cs @@ -233,7 +233,17 @@ public class ProductImportService : IProductImportService // Import variations if provided if (!string.IsNullOrEmpty(importDto.Variations)) { - await ImportProductMultiBuysAsync(product.Id, importDto.Variations); + // Check format: if it contains semicolons with 3 parts, treat as variants + // Format: "10; 30.00; 100|25; 70.00; 50" (value; price; stock) + // Old multi-buy format: "Single Item:1:10.00;Twin Pack:2:19.00" (name:quantity:price) + if (importDto.Variations.Contains(';')) + { + await ImportProductVariantsAsync(product.Id, importDto.Variations); + } + else + { + await ImportProductMultiBuysAsync(product.Id, importDto.Variations); + } } // Import photos if provided @@ -256,6 +266,42 @@ public class ProductImportService : IProductImportService } } + private async Task ImportProductVariantsAsync(Guid productId, string variationsText) + { + // Format: "10; 30.00; 100|25; 70.00; 50|50; 130.00; 25" (value; price; stock separated by |) + var variations = variationsText.Split('|', StringSplitOptions.RemoveEmptyEntries); + + for (int i = 0; i < variations.Length; i++) + { + var parts = variations[i].Split(';', StringSplitOptions.RemoveEmptyEntries); + if (parts.Length >= 3) + { + var variantValue = parts[0].Trim(); + var priceOverride = decimal.Parse(parts[1].Trim(), CultureInfo.InvariantCulture); + var stockQuantity = int.Parse(parts[2].Trim()); + + // Determine variant type based on the value format + string variantType = variantValue.ToLower().Contains("g") ?
