为什么我得到docker @ postgres错误：关系“accounts_myprofile”不存在？

标签： django postgresql docker postgis

所以我正在研究Django / Postgres项目。

当我运行docker-compose时，项目将在一个容器中启动Django而在另一个容器中启动Postgres。我可以查看我的项目的某些URL，但查询MyProfile模型的URL都会导致以下错误：

docker@postgres ERROR:  relation "accounts_myprofile" does not exist

我跑了两个：

docker-compose run web python manage.py makemigrations

和

docker-compose run web python manage.py migrate

我不确定这是否重要，但这回复于：

Operations to perform:
  Apply all migrations: admin, auth, cities, contenttypes, django_messages, easy_thumbnails, guardian, sessions, sites, userena
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

在下面附加我的docker-compose和Django设置。

答案 0 :(得分：0)

出于某种原因跑步：

docker-compose run web python manage.py makemigrations accounts

docker-compose run web python manage.py migrate accounts

返回此

Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied

但实际进入Django容器并直接运行

python manage.py makemigrations accounts
python manage.py migrate accounts

这很有效，我的项目现在完全没有数据库错误。

所以我的问题已经解决但我无法告诉你为什么用docker-compose运行这个命令对我来说似乎不起作用。
