在 Django model 的情况下，

Question

In the django code in order to make a model,

for example,

class Student(models.Model):
    name = models.CharField(max_length = 200) 

Why models.CharField(max_length = 200). Why can't we write only name=CharField(max_length = 200)

Answer 1

You can . You should only import that field in the scope, for example with:

from django.db import models
from django.db.models import CharField  # 🖘 import CharField

class Student(models.Model):
    name = max_length=200  # 🖘 use CharField

The field classes like CharField , IntegerField , … are all members of the django.db.models module, so you can import these in the head of the file.

You can also import Model and thus work with:

from django.db import models
from django.db.models import CharField, Model  # 🖘 import Model

class Student():  # 🖘 use Model
    name = CharField(max_length=200)
