在 django-python 中迁移我的数据库时出现错误

Question

我将我的数据库 django 默认更改为 postgresql，当我尝试迁移时... django.db.utils.OperationalError: FATAL: password authentication failed for user "hamid"

我的设置是 安装 psycop2 但我不明白我的错误，因为我可以通过这个密码进入 shell 数据库但是当我迁移时我有错误

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'postgres',
        'USRE': 'postgres',
        'PASSWORD': 'postgres',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

还有我的 docker-compose.yml

version: '3'

services:
  blogpy_postgresql:
    image: postgres:12
    container_name: blogpy_postgresql
    volumes:
      - blogpy_postgresql:/var/lib/postgresql/data
    restart: always
    env_file:.env
    ports:
      - "5432:5432"
    networks:
      - blogpy_network

volumes:
  blogpy_postgresql:
    external: true
networks:
  blogpy_network:
    external: true

还有我的 .env

POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres
POSTGRES_DB=postgres

还有我的回溯

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError: FATAL:  password authentication failed for user "hamid"

我使用python3 和 Django 2.2

您的数据库设置中有错字。

'USRE': 'postgres',

应该是

'USER': 'postgres',
