From 69b56ed582941602d2cc5f52c20668d10b0c0f92 Mon Sep 17 00:00:00 2001 From: paul Date: Tue, 8 Jul 2025 17:57:26 +0200 Subject: [PATCH] Implement multi-language email templates MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add language columns to email_templates table (subject_en/de, body_html_en/de, body_text_en/de) - Update adminEmail.js routes to support language-specific templates - Create EmailProcessor service to handle language selection based on recipient - Update EmailConfigPage component with language tabs similar to CMS pages - Add German translations for all email templates - Update all email queue usage to use proper template keys - Add missing email templates (gallery_expired, archive_complete) - Integrate email processor service into main server startup The system now automatically selects the appropriate language (English/German) based on the recipient's email domain or preferences. đŸ€– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- backend/data/photo_sharing.db | Bin 102400 -> 110592 bytes ...add_language_support_to_email_templates.js | 35 +++ .../009_update_german_email_templates.js | 67 +++++ .../010_add_missing_email_templates.js | 57 +++++ backend/server.js | 4 + backend/src/routes/adminEmail.js | 91 ++++--- backend/src/routes/adminEvents.js | 20 +- backend/src/routes/events.js | 18 +- backend/src/services/archiveService.js | 12 +- backend/src/services/emailProcessor.js | 228 ++++++++++++++++++ backend/src/services/expirationChecker.js | 47 ++-- frontend/src/pages/admin/EmailConfigPage.tsx | 71 +++++- frontend/src/services/email.service.ts | 16 +- 13 files changed, 564 insertions(+), 102 deletions(-) create mode 100644 backend/migrations/008_add_language_support_to_email_templates.js create mode 100644 backend/migrations/009_update_german_email_templates.js create mode 100644 backend/migrations/010_add_missing_email_templates.js create mode 100644 backend/src/services/emailProcessor.js diff --git a/backend/data/photo_sharing.db b/backend/data/photo_sharing.db index 92bd487404b83362f1c5442ee4d16ead62196752..bd02bbb5a554752f62d467a8816125d01a2069d5 100644 GIT binary patch delta 5943 zcmeHLO>7(25#BW^CSEIA1#!?KM$spxPArI&XfaG;MGzv}iW)dhzsluLnLdI}13-Y%CC zMafoM^d>?Q#JBIwoB8IO*_nC!v&7r?64&=VIZ@0(B)%}Wzp zjko?Wv6l=dhOR66U-aMUujvmD-5I*x8X=d4{6mSjaw3~Kn8{Pq%$IG>ZP&^}nc7ZX zK)LEr0et)|KAD-!r8Cc^GtZNQxv5-sDwlg|%w_F&4_&TX)Nz2V!cCtn#AVK;jbU}$EPQ%ftXVz z2=C{3@e&XNz$KIwO7;?%q*!5u(;_SaRMAD_sX9P8 zkV3^3v>@an3CtwaEZeTl1)~DxQ9){cEm#ZDuGiOTL*2#T26?k5X+b1lp`E-$nOxz( zmh1wIL^d1-E(imQGLxsK4K^cs9@z>tO}j5%<7A;9 zgMRCKjVE>=rsL<5YXnKAk{z&o86e5uY!VeOml%+j&?qDkFdH`7gWwZtSm02v2yTZ~ z!Nzr~5wrS)72CHNN!Duqno{+85~;LaDDjY8u3abzQic*E7d@+e!?he->ALqQY9_Vh zWZ7dT673@Tmg5d!_+{2B8n8@D%tIfC6tsbfaqoi`m5@lGSbB z6t)F!iY$XGCE~U~A~9?s04Y!8>TC}KJy)QRTCW?rN}jR7!6Qc{69dal6#1$rE_y!d z<+;c{;DH(G4!hDPLqhT{BahpH6d52S(teaS&)T=!pQ4_Uo<}jlB@Es35j!_WzROKN zOc&e7UDNsyUytiyu*qRCDJzmi8MKQ6@$O(4!qx_!3<)or{abu5glK#!GHs76dhKo@F;1fqTuhl0ExQB zQ(qFbBiMFPgh^L;p2=5@i>U;Y?5`0nnWI`d5A=!T|0`PE1eG8EHhc-fO<5ZDF^j-QVJ^4Bp>w z@q0(qVP$OY+CXEu@j`a)+I+)nP2K(TCQg%f8psV>jI8$cH!md`v1AIi3vD8(t4G?B!WZZb8gAR7TTc`=;xH8?Y_%d}yKHi{t-9fFQm0 zA%}&^6EO|{#`Vt?{d4_0{qOppWcd<&T2EwtuaEAHrPa>sKVPU|DFy=KkHyARtGAAc zwZ8jd?8W_fQde_|UelFF8ftFv-k!hhS=jZ}!&e{rYvTKa6+fbVpbcSZq^sH$W$>Y& zjg6^SpKJbM*C&HX?ip`ELFBQFi1K5pY2ew}QW(4rm1rF6;rPez zf2fL~M-cUx`mLhz1*cBk;%DLi)yPkaUK6rRfw4KfbKI21evQZ|Z=i8hJTA32g}5^KgDduw4(QM`35aNO5LltPMEA$r1KqXm8M`;=o9bpn~f| S1J16E&;BzDA`fk;`o97D5>f>K delta 252 zcmZp8z}B#UZGyC*B?AM4BoM=Z{6rmNM$3%}()x_dlWX*g8JRYJ&=*nQV&?Z};6KIR z&F{Zi(7=&@vw!@?1Rh?XE+%e%23{R*{>_2{%-nn}QcT07KV4TmS$7 diff --git a/backend/migrations/008_add_language_support_to_email_templates.js b/backend/migrations/008_add_language_support_to_email_templates.js new file mode 100644 index 0000000..4071850 --- /dev/null +++ b/backend/migrations/008_add_language_support_to_email_templates.js @@ -0,0 +1,35 @@ +exports.up = async function(knex) { + // Add language-specific columns to email_templates + await knex.schema.alterTable('email_templates', function(table) { + // Add English versions (rename existing columns for consistency) + table.renameColumn('subject', 'subject_en');
