我一直在尝试使用 cookiecutter-django 在本地建立一个新的 django 项目。我已按照文档进行操作，但在尝试运行时不断出错python manage.py migrate。

错误回溯。

我真的不知道在设置项目时我做错了什么，如果您检查我采取的步骤并帮助我找出缺少的内容，我将不胜感激。

使用 cookiecutter-django 设置项目的步骤：

pip、virtualenv、PostrgreSQL 已经安装

  1. pip install cookiecutter
  2. cookiecutter https://github.com/pydanny/cookiecutter-django
  3. 回答千篇一律的问题
  4. 创建 virtualenv -virtualenv -p /usr/bin/python3 venv
  5. 激活 virtualenv -source venv/bin/activate/
  6. cd intoprojectfolder
  7. 文档说sudo ./install_os_dependencies.sh install但是 ./install_os_dependencies.sh 不在 projectroot 中，文件在实用程序/中找到
    • cd utility
    • sudo ./install_os_dependencies.sh install
  8. pip install -r requirements/local.txt
  9. 在 postgresql 中设置数据库：
    • sudo su - postgres
    • psql
    • CREATE DATABASE myproject;
    • CREATE USER myprojectuser WITH PASSWORD 'password';
    • GRANT ALL PRIVILEGES ON DATABASE myproject TO myprojectuser;
    • \q
  10. 返回 tu 项目根目录
  11. mv env.example .env
  12. export DATABASE_URL=postgres://myprojectuser:myprojectuserdbpassword@127.0.0.1:5432/myproject
  13. python manage.py migrate

在那之后，当我得到回溯时，可能出了什么问题？文档没有显示更多信息，迁移应该可以工作。

Cookiecutter 使用项目名称的 slug 作为您要使用的开发数据库的名称。您需要自己创建数据库。

从你的堆栈跟踪这里是从你的 settings.py 文件中给你问题的行：

File "/home/ubuntu/lasbrisas_project/django_condominios/config/settings/common.py", line 102, in <module>'default': env.db('DATABASE_URL',     default='postgres:///django_condominios'),

它期望找到一个名为django_condominios的数据库。

您可以通过运行来解决此问题

createdb django_condominios

你应该很好地运行你的迁移。
