dsb*_*afe 5 database migration django postgresql heroku
我在 Django 中有一个应用程序,我在 heroku 中部署了它。部署运行良好,但我的模型的数据库没有迁移。
部署后,我再次本地运行:
python manage.py makemigrations
python manage.py migrate
Run Code Online (Sandbox Code Playgroud)
之后,我这样做:
heroku run python manage.py makemigrations
heroku run python manage.py migrate
Run Code Online (Sandbox Code Playgroud)
在我运行服务器并等待它运行良好之后:
heroku run python manage.py runserver
Run Code Online (Sandbox Code Playgroud)
我有 3 个模型:
客户、类别、产品
produto有一个ForeignKey到categoria。所以,本地,我有 3 个数据库:
produtos_produto, produtos_categoria, cliente.
我PostgreSQL在本地和heroku中用作数据库。
但是在 heroku 中,我没有任何这些数据库。
当我运行服务器时,在浏览器中我有以下答案:
ProgrammingError at /
