From 3f789785cabe59aaa1d48d2c9b72ab283a886ed5 Mon Sep 17 00:00:00 2001 From: Andrey Smakotin Date: Tue, 18 Nov 2025 21:29:14 +0300 Subject: [PATCH] Add ProductKit binding to ConfigurableKitProductAttribute values MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implementation of kit binding feature for ConfigurableKitProduct variants: - Added ForeignKey field `kit` to ConfigurableKitProductAttribute * References ProductKit with CASCADE delete * Optional field (blank=True, null=True) * Indexed for efficient queries - Created migration 0007_add_kit_to_attribute * Handles existing data (NULL values for all current records) * Properly indexed for performance - Updated template configurablekit_form.html * Injected available ProductKits into JavaScript * Added kit selector dropdown in card interface * Each value now has associated kit selection * JavaScript validates kit selection alongside values - Updated JavaScript in card interface * serializeAttributeValues() now collects kit IDs * Creates parallel JSON arrays: values and kits * Stores in hidden fields: attributes-X-values and attributes-X-kits - Updated views _save_attributes_from_cards() in both Create and Update * Reads kit IDs from POST JSON * Looks up ProductKit objects * Creates ConfigurableKitProductAttribute with FK populated * Gracefully handles missing kits - Fixed _should_delete_form() method * More robust handling of formset deletion_field * Works with all formset types - Updated __str__() method * Handles NULL kit case Example workflow: Dlina: 50 -> Kit A, 60 -> Kit B, 70 -> Kit C Upakovka: BEZ -> Kit A, V_UPAKOVKE -> (no kit) Tested with test_kit_binding.py - all tests passing - Kit creation and retrieval - Attribute creation with kit FK - Mixed kit-bound and unbound attributes - Querying attributes by kit - Reverse queries (get kit for attribute value) Added documentation: KIT_BINDING_IMPLEMENTATION.md 🤖 Generated with Claude Code Co-Authored-By: Claude --- KIT_BINDING_IMPLEMENTATION.md | 334 ++++++++++++++++++ .../migrations/0007_add_kit_to_attribute.py | 31 ++ myproject/products/models/kits.py | 25 +- .../products/configurablekit_form.html | 100 ++++-- .../products/views/configurablekit_views.py | 140 ++++++-- myproject/test_card_interface.py | 145 ++++++++ myproject/test_kit_binding.py | 236 +++++++++++++ 7 files changed, 948 insertions(+), 63 deletions(-) create mode 100644 KIT_BINDING_IMPLEMENTATION.md create mode 100644 myproject/products/migrations/0007_add_kit_to_attribute.py create mode 100644 myproject/test_card_interface.py create mode 100644 myproject/test_kit_binding.py diff --git a/KIT_BINDING_IMPLEMENTATION.md b/KIT_BINDING_IMPLEMENTATION.md new file mode 100644 index 0000000..a8ae802 --- /dev/null +++ b/KIT_BINDING_IMPLEMENTATION.md @@ -0,0 +1,334 @@ +# Kit Binding for ConfigurableKitProduct Attributes -
