ProgrammingError: relation “django_session” does n

问题:

I started to develop a Django base web application. Everything were fine until I installed Psycopg2 for my database which I created in PstgreSql. Now when I'm trying to open any page in my site, it throws ProgrammingError: relation "django_session" does not exist error.

Request Method:     GET
Request URL:    http://127.0.0.1:8000/login/
Django Version:     1.7
Exception Type:     ProgrammingError
Exception Value:    

relation "django_session" does not exist
LINE 1: ...ession_data", "django_session"."expire_date" FROM "django_se...
                                                             ^

Exception Location:     /home/alex/.virtualenvs/startDjango/local/lib/python2.7/site-packages/django/db/backends/utils.py in execute, line 65
Python Executable:  /home/alex/.virtualenvs/startDjango/bin/python

This is my database setting in Setting.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'myDB',
        'USER': 'alex',
        'PASSWORD': 'mypassword',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

I'm developing in virtualenvs

Any idea how to fix this? Thanks

回答1:

If you change the database, you should create database for the new database.

Use manage.py migrate command. (or manage.py syncdb if you used it for old database).

回答2:

You can alternatively migrate just the sessions app if you have already run migrate and still getting the error

python manage.py migrate sessions

Thats works perfect for my in Docker deploy.
