Confusing Instructions for Running the Database Client in Django Tutorial Part 2

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hi,
I’m new to Django and have completed the Overview, Installation, and Part 1 of the tutorial. In Part 2, after setting up the database and running the migrate command, the tutorial instructs to run the command-line client for your database to view Django-created tables using commands like \dt (PostgreSQL), SHOW TABLES; (MariaDB, MySQL), .schema (SQLite), or SELECT TABLE_NAME FROM USER_TABLES; (Oracle).

On Windows 10 PowerShell, I tried:

POWERSHELL
py manage.py migrate \dt .schema

which resulted in:

PLAINTEXT
CommandError: No installed app with label '\dt'.

I then searched for command-line client django and found the dbshell documentation which explains that django-admin dbshell is used to run the command-line client. However, when I ran:

POWERSHELL
django-admin dbshell \dt .schema

I got the following error:

PLAINTEXT
django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I find this part of the tutorial confusing and frustrating as a beginner. I just wanted to share my experience and point out that these instructions did not work as expected.

Django Database Shell Help

I understand your frustration with the Django tutorial. There's a misunderstanding in how the database commands should be executed. Let me clarify:

The tutorial is asking you to do two separate things:

First, run the Django migrations with py manage.py migrate
Then, separately, open your database's command-line client to inspect the tables

The database commands like \dt or .schema are meant to be run inside the database shell, not as arguments to Django commands.

Here's the correct approach for SQLite (which is Django's default database):

POWERSHELL
# First run migrations
py manage.py migrate

# Then open the database shell
py manage.py dbshell

Once inside the database shell, you can run SQLite commands like:

.tables
.schema

The py manage.py dbshell command opens the appropriate database client for your configured database. Using django-admin dbshell didn't work because it doesn't know which settings file to use.

If you're having trouble with the dbshell command, you can also directly open SQLite (assuming that's what you're using) with:

POWERSHELL
sqlite3 db.sqlite3

from your project directory.
