From f03a52bd77b407cc04e1222a75b3455607079fec Mon Sep 17 00:00:00 2001 From: Aguinaldo Tupy <44652991+aguinaldotupy@users.noreply.github.com> Date: Thu, 18 Sep 2025 06:55:31 -0300 Subject: [PATCH] feat: Add `media_name` support for WhatsApp templates document files (#12462) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Description This implementation adds support for the `media_name` parameter for WhatsApp document templates, resolving the issue where documents appear as "untitled" when sent via templates. **Problem solved:** Documents sent via WhatsApp templates always appeared as "untitled" because Chatwoot didn't process the `filename` field required by the WhatsApp API. **Solution:** Added support for the `media_name` parameter that maps to the WhatsApp API's `filename` field. ## Type of change - [x] New feature (non-breaking change which adds functionality) - [x] This change requires a documentation update ## How Has This Been Tested? Created and executed **7 comprehensive test scenarios**: 1. ✅ Document without `media_name` (backward compatibility) 2. ✅ Document with valid `media_name` 3. ✅ Document with blank `media_name` 4. ✅ Document with null `media_name` 5. ✅ Image with `media_name` (ignored as expected) 6. ✅ Video with `media_name` (ignored as expected) 7. ✅ Blank URL (returns nil appropriately) **All tests passed** and confirmed **100% backward compatibility**. ## Technical Implementation **Backend Changes:** - `PopulateTemplateParametersService`: Added `media_name` parameter support - `TemplateProcessorService`: Pass `media_name` to parameter builder - `WhatsappCloudService`: Updated documentation with `media_name` example **Frontend Changes:** - `WhatsAppTemplateParser.vue`: Added UI field for document filename input - `templateHelper.js`: Include `media_name` for document templates - `whatsappTemplates.json`: Added translation key for document name placeholder **Key Features:** - 🔄 **100% Backward Compatible** - Existing templates continue working - 📝 **Document Filename Support** - Users can specify custom filenames - 🎯 **Document-Only Feature** - Only affects document media types - ✅ **Comprehensive Testing** - All edge cases covered ## Expected Behavior **Before:** ```ruby # All documents appear as "untitled" { type: 'document', document: { link: 'https://example.com/document.pdf' } } ``` **After:** ```ruby # With media_name - displays custom filename { type: 'document', document: { link: 'https://example.com/document.pdf', filename: 'Invoice_2025.pdf' } } # Without media_name - works as before { type: 'document', document: { link: 'https://example.com/document.pdf' } } ``` ## Checklist: - [x] My code follows the style guidelines of this project - [x] I have performed a self-review of my code - [x] I have commented on my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [x] Any dependent changes have been merged and published in downstream modules Co-authored-by: Muhsin Keloth --- .../whatsapp/WhatsAppTemplateParser.vue | 22 +++++++++++++++++++ .../helper/specs/templateHelper.spec.js | 1 + .../dashboard/helper/templateHelper.js | 5 +++++ .../i18n/locale/en/whatsappTemplates.json | 1 + .../populate_template_parameters_service.rb | 15 ++++++++----- .../providers/whatsapp_cloud_service.rb | 6 ++++- .../whatsapp/template_processor_service.rb | 5 +++-- 7 files changed, 46 insertions(+), 9 deletions(-) diff --git a/app/javascript/dashboard/components-next/whatsapp/WhatsAppTemplateParser.vue b/app/javascript/dashboard/components-next/whatsapp/WhatsAppTemplateParser.vue index cf62a6d5d..6df06642c 100644 --- a/app/javascript/dashboard/components-next/whatsapp/WhatsAppTemplateParser.vue +++ b/app/javascript/dashboard/components-next/whatsapp/WhatsAppTemplateParser.vue @@ -72,6 +72,10 @@ const formatType = computed(() => { return format ? format.charAt(0) + format.slice(1).toLowerCase() : ''; }); +const isDocumentTemplate = computed(() => { + return headerComponent.value?.format?.toLowerCase() === 'document'; +}); + const hasVariables = computed(() => { return bodyText.value?.match(/{{([^}]+)}}/g) !== null; }); @@ -126,6 +130,11 @@ const updateMediaUrl = value => { processedParams.value.header.media_url = value; }; +const updateMediaName = value => { + processedParams.value.header ??= {}; + processedParams.value.header.media_name = value; +}; + const sendMessage = () => { v$.value.$touch(); if (v$.value.$invalid) return; @@ -168,10 +177,12 @@ defineExpose({ processedParams, hasVariables, hasMediaHeader, + isDocumentTemplate, headerComponent, renderedTemplate, v$, updateMediaUrl, + updateMediaName, sendMessage, resetTemplate, goBack, @@ -225,6 +236,17 @@ defineExpose({ @update:model-value="updateMediaUrl" /> +
