Question 🤔
- Sizda News degan model bor va List and Detail API chiqarishingiz kerak. Bunda List va Detail API'lar bir nechta filed'lar bilan farq qiladi holos.
- Bu holat uchun siz serizalizer'ni qanday yaratasiz?🤔
p.s) Kechroq o'z varyantimi tashlayman )

* DynamicFieldsModelSerializer yaratish orqali loyhalargizdagi serializer’larni 1ta class orqali yaratishingiz va kerak bo’lgan field'larni view uzidan serializer'ga attribute sifatida berib qabul qilishingiz mumki bo’ladi.✔️ 👌

Xavfsizlik next level. 🤦♂️
Yaqinda Nest.Js(ts) da qilingan loyha topshirishgan edi. Undagi oddiy login qismi biroz hayron qoldirdi 😕
Frontend foydalanuvchi kiritgan password’ni sha256'da hash’lab backend’ga yuborar edi va backend uni bazada bcryt.hash() da hashlanib saqlangan parol bilan compare qilib tekshirar edi.
Savol. Frontend nega parolni sha256 da yuborgan va uni backenda bcryt.hash() lab tekshirgan deb uylaysiz ?! 👇 (erkin fikrlar)

#Savol
- Qanday qilib bajaralayotgan taskni realtime'da progress foizlarda kursatib turish mumkin?🤯
Example:
- [2 - 3 000 000] gacha bulgan sonlar orasida nechta tub sonlar mavjudligini hisoblavchi web task'ni necha foizi bajarilgani qanday qilib realtime'da userga ko'rsatib turish mumkin?
p.s: Bu file upload progress'ga uxshashroq bo'ladi.👌
Erkin fikr idea'lar ?👇

Django'dagi N+1 haqida ko'p eshitganmiz 🥺
Masalan:
1 - rasmda Option'ga references bog'liq bo'lgan question title'ga olishda bu sodir bulmoqda deyishimiz mumkin.
💡 Prefetch_related / select_related django ORM'dagi mu methodlarni chuquroq o'rganib chiqish ham tavsiya etiladi
p.s) Prefetch_related / select_related shunchalik yaxshi narsami? Bularda kamchilik, minuslari bormi ?🤔 (https://chatgpt.com/share/30eb7a6e-fcab-4751-b110-ce6bac6d5cd1)
Fikr, idealar 👇📝

#django #pdf #qrcode
Bazi loyhalarda saqlangan .PDF fayl ichiga usha .PDF fayl turgan linkni QRCode qilib joylashtirish zarur bo'ladi. 📑
Bunda odatda:
1) .PDF fayl generate qilish.
2) Generate bo'lib saqlangan .PDF fayl path'dan QrCode generate qilish
3) Yaratilgan QrCode faylni berilgan cordinatalar asosida .PDF filega joylsahtirib, .PDF faylni qayta saqlab
4) PDF faylni path'ni file model field'ga berib saqlash ham zuru buladi 😓🤧
⚠️ Bazi loyhalarimda oldin ishlatgan hard coding varyantim bilan ulashaman, bu borada sizga foydasi tegib qolishi mumkin:
* https://gist.github.com/firdavsDev/873c71a44546c8630060f232ece3f367
p.s) Siz qanday varyantlarni qulagansiz bu borada? 👇📝

1chi varyant unchalik ham effectiniy emas. Bu ko'p vaqt talab qiladigan task hisoblanadi va CPU/RAM da sezilari joy ham egalaydi. (pdf yaratish + va yana faylni read qilib ochib ichiga qrcode png joylash + va pdf'ni qayta saqlash) ☄️
2 - varyant: FrontSide'da hal qilish.💻
Bunda:
- FrontEnd'da ham bir nechta foydali package'lar mavjud (PDFKit, jsPDF ...)
- Backendga surov yuborib, kelgan response data'ni A4 page sifatida userga kursatish va user hohlasa chop etish tugmasi orqali sahifani PRINT qilib yuklab olishi mumkin bo'ladi.
* Bunda pdf generate qilish Browser'ga (CTRL + P) yuklatiladi holos )💻 ✔️
❗️ Shaxsiy fikr (client imkon qadar BAZIDA dumb bolishi kerak)🙂
