Deleting unused Django media files 🗑
Tasavur qilingki sizning 1 yil oldingi kodingizda ko'p marotaba update qilinadigan File field model bor. Bazada 4K oshiq bunday datalar mavjud va ularning 80% (deyarli) 3 kunda 10 mb file yuklanib yangilanib boriladi. Natijada ortiqcha eski filelar o'chirilmay MEDIA_ROOT papkada saqlanib qolavergan.
Savol:
- Hozirgi vaziyatda qanday qilib havfsiz ravishda MEDIA_ROOT ni keraksiz faylardan tozalashimiz mumkin?
p.s) Boshidan hech qanday remove qilish uchun signallar va save() metod overide qilinmagan

Loyhaning coding jarayoni tezlashtirishning bir necha yo'lari mavjud.
Productiondagi loyhaga qo'shilishi kerak bo'lgan yangi API'larni test qilish maqsadida kompyuterizdagi 127.0.0.1:8000'da ishlab turgan loyhani frontend, mobile dasturchilarga berish orqali ham testlashingiz mumkin bo'ladi.
Bu orqali siz vaqtingizni tejab qolishingz mumkin. Agar error yoki yangi qo'shimcah field qo'shib yuborish talab etilsa joyida qushasiz va boshqa dasturchilarga ham ko'rinadi bu.
Bunda siz bir nechta texnalogiyalar ishlatishingiz mumkin: (man bilganlari)
* ngrok.com
* jprq.io
* ...
Lekin agar Frontendchi yoki Mobile dasturchilar bilan bita wifi'da ulanib turgan bo'lsangiz bular sizga kerak emas. shunchaki siz ularga kompyuteringiz IP manzilini va loyhangiz port'tini uzatishingiz uzi yetarli bo'ladi.😉
p.s) API'ni berishdan oldin PostMan'da o'ziz barbir testdan o'tkazib keyin berganiz ma'qul ham 😁

Bilim bilan bo’lishish uchun sabablar.
1) bilim - bo’lishsangiz ko’payaveradigan yagona boylik.
2) bilimdan yaxshi boylik yo’q. puli bor odam mulkidan faqat bir qisminigina (2.5%) zakotga to’lashi kerak. bilimi bor inson esa bilimi bilan 100/100 qismini ulashishi kerak.
3) Allohga ming shukurki, atrofimda oxirgi tomchisigacha bilim ulashgan odamlar orasida bo’ldim. bu insonlar kimdir ular yordamida undanda yaxshiroq bo’lib ketishi mumkin deb o’ylamagan. kimdir ularga tegishli bo’lgan biron narsani olib qo’ymoqchi, degan fikrga kelmagan. chunki bunday insonlar qazo va qadarga qattiq ishonishadi. ularga tegishli narsani hech kim olib qo’yolmasligini juda yaxshi bilishadi. ya’ni rizq tushunchasi bor. birovga tegishlik narsalar bizga kelmaydi, bizniki bo’lgan narsalar esa birovga ketib qolmaydi.
4) hozir ham men shunday insonlar bilanman. ularga savol bersam ortig’i bilan javob beradilar. bunday insonlardan "Alloh rozi bo’lsin”.
5) shu narsa meni kasbim sirlari bilan bo’lishishga undaydi. men yetgan nuqtagacha eng qisqa yo’lni ko’rsatish, vaqtdan yutishlari uchun bilimlarim bilan bo’lishishni o’zimga odat qilib oldim. misol: men 2 yil ketkazgan narsaga 1 yil ketkazishlari uchun. ko’p narsaga erishishlarini istayman. faqat shundagina biz rivojlangan ummatga aylanamiz.
-
qisqasi nima demoqchiman:
- amallar niyatlarga bog'liq.
imkoniyatlar, bilim va kontaktlar bilan bo’lishing. kimdir sizdan yaxshiroq bo’lishidan qo’rqmang. agar siz, sizning qo’shningiz/do’stingiz/kursdoshlaringiz/atrofingizdagi insonlar eng yaxshisi bo’lishmasa unda boshqa bir davlat yoki millat vakillari ustun bo’lishadi - biz emas. “bilganing bilan bo’lishsang, boshqalar sendan aqlli bo'lib ketadi” degan maqolga amal qilmang.
p.s) Shu bois o'z o'rgangan bilimingizni 10% boshqalar bilan ulashishga harakat qiling, kanal ochib, qandaydir loyhangizda duch kelgan mumammo va uni hal qilishda qilgan ishlarinigizni yoritib borishingiz ham mumkin.
