Field types ​

Proyektdagi istalgan bir ma'lumot, masalan mahsulotlar to'g'risidagi ma'lumotlarning jadval ko'rinishi:

Bu jadval asosida djangoda model tuzishdan oldin har bir ustunda qanday turdagi ma'lumotlar saqlanishiga aniqlik kiritib olishimiz kerak.

Masalan nomi nomli ustunda str toifasidagi ma'lumotlar saqlanishini va uzunligi ko'pi bilan 50ta belgidan iborat bo'lishini istasak, u holda

from django.db import models

class Mahsulot(models.Model):
    nomi = models.CharField(max_length=50)
    ...

from django.db import models

class Mahsulot(models.Model):
    nomi = models.CharField(max_length=50)
    ...

narxi nomli ustunga to'xtaladigan bo'lsak, bu fieldga faqat int toifasidagi ma'lumotlarni kiritish mumkin deb belgilasak, eng to'g'ri yechim bo'ladi. Buning uchun djangodagi IntegerField to'g'ri keladi.

from django.db import models

class Mahsulot(models.Model):
    nomi = models.CharField(max_length=50)
    narxi = models.IntegerField()
    ...

from django.db import models

class Mahsulot(models.Model):
    nomi = models.CharField(max_length=50)
    narxi = models.IntegerField()
    ...

tavsifi nomli ustunda str toifasidagi ma'lumotlar saqlansada, katta hajmdagi matn kiritilishini hisobga olib, djangodagi TextFielddan foydalanishi maqsadga muvofiq bo'ladi.

from django.db import models

class Mahsulot(models.Model):
    nomi = models.CharField(max_length=50)
    narxi = models.IntegerField()
    tavsifi = models.TextField()

from django.db import models

class Mahsulot(models.Model):
    nomi = models.CharField(max_length=50)
    narxi = models.IntegerField()
    tavsifi = models.TextField()

Yuqorida faqat CharField, IntegerField, TextField ko'rib chiqildi. Ular haqida batafsil ma'lumot olish va boshqa field turlari bilan tanishish uchun bu yerga bosing.
