我尝试在 ubuntu 18.04 上将 django 与 postgreSQL 连接

Question

I am newbie on django , and I am facing the following issue. I have search for solution on the web but I couldn't find any yet.

 File "/home/r00t/projects/mp/mp/lib/python3.6/site-packages/django/db/backends/postgresql/base.py", line 187, in get_new_connection
    connection = Database.connect(**conn_params)
  File "/home/r00t/projects/mp/mp/lib/python3.6/site-packages/psycopg2/__init__.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: invalid port number: "<5432>"

settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql'
        'NAME': '<mpdb>',
        'USER': '<admin>',
        'PASSWORD': '<r00t>',
        'HOST': '<127.0.0.1>',       
        'PORT': '<5432>',
    }
}

I have tried the following: port no: correct database name: correct user name: correct password: correct

Could you please help me out with thanks

Answer 1

When you see <foo> in descriptions or examples, it usually means you are supposed to replace those contents including the angle brackets with the real value. So after replacement the angle brackets are no longer there. It looks like you have left the literal < and > in place, which is wrong.
