Question

我是Django的新手。我正在学习一个教程，在该教程中我应该创建一个称为产品的模型类。

这就是我包含在名为“产品”的APP中的models.py文档中的内容：

class Products (models.Model):
title = models.TextField()
description = models.TextField()
price = models.TextField()

然后，将我的应用程序添加到我的setting.py文档中的已安装的应用程序中：

    INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    #third party

    #own
    'products',

但是，当我尝试在终端上运行以下命令时，出现错误：

(env) dcorreavi@dcorreavi src % python manage.py makemigrations
Traceback (most recent call last):

ModuleNotFoundError: No module named 'products'

Answer 1

尝试一下：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'products.apps.ProductsConfig',
]

而不只是products

Answer 2

“ products.apps.ProductsConfig”已添加到设置中已安装的应用部分

ModuleNotFoundError：没有名为“产品”的模块
