How to view database and schema of django sqlite3 db
Question:
I’m new to django framework.
I tried to create a simple blog by following djangogirls tutorials.
Here by default, we get sqlite3 as default database Engine:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
I tried some ORM queries also, Even performed some row sql queries
At my django project, I have this db.sqlite3 file:
blog db.sqlite3 env manage.py mysite
My Question: How to know the schema that django created in this db.sqlite3(I know mysql where I can see details about each database and tables, so here I just want to know more things in sqlite)
I have sqlite3 in my system and I tried .database command, but it just shows me:
seq name file
--- --------------- ----------------------------------------------------------
0 main
Answers:
Goto the folder where the database is and then
sqlite3 db.sqlite3
Then
.tables
or
.schema
depending on what you want. Instead of invoking sqlite3 directly you could do
python manage.py dbshell
and then type the sqlite commands.
If you are working with a legacy database you can generate Django models for that using the
python manage.py inspectdb
please see https://docs.djangoproject.com/en/3.0/ref/django-admin/#django-admin-inspectdb for additional info.
But please do yourself a favour and get a GUI database client. Life is much easier when you have one.
You can use the following command to get the sql script for the database created.
python manage.py sqlmigrate app_label migration_name
You can view your db.sqlite file online.
sqlite Online
Just upload your file there and you can see your tables which are in your db.sqlite file.
I have been stumbling around for an hour aiming to replicate DESCRIBE
table inside the Django shell, and think I’ve cracked it.
I hope this is of use to others.
In the Terminal – enter the following commands.
python3 manage.py dbshell
.tables
Find the name of the table you are looking for, then run the following commands:
.header on
.mode column
pragma table_info('table you are looking for');
Do not forget the semicolon in the last instruction.
Just wanted to add that someone can find the migrations under my_project_name>my_app_name>migrations and usually you pick the one with the biggest number.
Then the command should be like: python manage.py sqlmigrate my_app_name number
First, run the command below:
python manage.py dbshell
To access sqlite3 command-line client as shown below:
Then, run the command below:
.table
Or run the command below:
.tables
To show all the tables in SQLite as shown below:
Then, run the command below:
.schema --indent store_product
To show the schema of "store_product" table as shown below:
