python - 在已添加到现有模型的产品模型字段上运行 makemigrate 时出错

问题描述

诚然，我是 django 的新手，尝试运行python manage.py makemigrations时出现以下错误

我正在尝试在我的类 Product(models.Model) 中添加一个新字段：featured = models.BooleanField()

代码

from django.db import models

# Create your models here.
class Product(models.Model):
    title       = models.CharField(max_length=120) # max_length = required
    description     = models.TextField(blank=True, null=True)
    price       = models.DecimalField(decimal_places=2, max_digits=10000)
    summary     = models.TextField()
    featured        = models.BooleenField()  #only new added line

错误：AttributeError：模块“django.db.models”没有属性“BooleenField”

command:
python manage.py makemigrations <enter>

entire_traceback:

解决方案

产品模型的代码中存在错误。我已经纠正了。

from django.db import models

class Product(models.Model):
    title       = models.CharField(max_length=120) # max_length = required
    description = models.TextField(blank=True, null=True)
    price       = models.DecimalField(decimal_places=2, max_digits=10000)
    summary     = models.TextField()
    featured    = models.BooleanField()  #only new added line

布尔字段的默认值始终为 false。
