Python Django 名称错误 : name 'model' is not defined

Question

我的一个应用程序中有一个模型，当我运行“python.py makemigrations signup”时会抛出错误。在过去的两天里，我一直在翻阅文档(和谷歌)试图弄清楚为什么会发生这个错误。不幸的是，我一无所获。

我想做的是在我的项目中包含一个应用程序。该应用程序位于我的 python 目录的根目录中(不在我的项目的子文件夹中)。这是我的代码:

from django.db import models

class CompanyInfo(models.Model):
        companyID = model.AutoField(primary_key=True)
        companyName = model.CharField(max_length=100)
        companyURL = model.URLField(max_length=100)
        companyEmail = model.EmailField(max_length=254)
        companyFEIN = model.CharField(max_length=50)
        companyUsername= model.CharField(max_length=100)
        companyPassword = model.CharField(max_length=100)

class CompanyContact(models.Model):
        ccID = model.AutoField(primary_key=True)
        ccFirstName = model.CharField(max_length=100)
        ccLastName = model.CharField(max_length=100)
        ccEmail = model.EmailField(max_length=254)
        ccPhone = model.IntegerField(max_length=20)

打印到控制台的确切错误如下:

NameError: name 'model' is not defined

Answer 1

看起来您在 models 上删除了“s”。您需要将 model 的使用更改为 models。

例如:

companyID = model.AutoField(primary_key=True)

需要:

companyID = models.AutoField(primary_key=True)
