Django模型定义报错：Field.__init__()收到意外关键字参数'max_lenght'

错误根源 #

触发TypeError: Field.__init__() got an unexpected keyword argument 'max_lenght'的直接原因是参数拼写错误：将CharField的合法参数max_length误写为max_lenght，Django无法识别该关键字参数，因此抛出错误。同时代码中存在其他拼写问题，一并修正如下：

需修正的拼写错误清单 #

• 模型类名：Coustomer → Customer
• 参数名：所有max_lenght替换为max_length（涉及locality、state、title、brand、category字段）
• 字段名：prodect_image → product_image
• ImageField参数：uploded_to → uploaded_to

修正后的完整代码 #

from django.db import models
# 注意：需确保User模型已正确导入，例如 from django.contrib.auth.models import User

class Customer(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    name = models.CharField(max_length=100)
    locality = models.CharField(max_length=150)
    zipcode = models.IntegerField()
    state = models.CharField(choices=STATE_CHOICES, max_length=100)

class Product(models.Model):
    title = models.CharField(max_length=100)
    selling_price = models.FloatField()
    discount_price = models.FloatField()
    description = models.TextField()
    brand = models.CharField(max_length=100)
    category = models.CharField(choices=CATEGORY_CHOICE, max_length=2)
    product_image = models.ImageField(uploaded_to='Productimg')
