Python sqlite3.OperationalError: no such table:

Question

I am trying to store data about pupils at a school. I\'ve done a few tables before, such as one for passwords and Teachers which I will later bring together in one program.

Answer 1

First you need to check if that table is 100% exist in the datbase you can use sqlite viewer for that https://inloop.github.io/sqlite-viewer/

if table exist then you can write your table name in '' for example

''' Select * from 'TableName' '''

what ever your query is I am just using Select * as an example

Answer 2

You are assuming that the current working directory is the same as the directory your script lives in. It is not an assumption you can make. Your script is opening a new database in a different directory, one that is empty.

Use an absolute path for your database file. You can base it on the absolute path of your script:

import os.path

BASE_DIR = os.path.dirname(os.path.abspath(__file__))
db_path = os.path.join(BASE_DIR, "PupilPremiumTable.db")
with sqlite3.connect(db_path) as db:

You can verify what the current working directory is with os.getcwd() if you want to figure out where instead you are opening the new database file; you probably want to clean up the extra file you created there.

Answer 3

I have to face same issue and there are a couple of approaches, but the one I think is the most probable one.

Maybe you are loading views or queries to database but you haven´t granted enough time for Django to migrate the models to DB. That's why the "table doesn't exist".

Make sure you use this sort of initialization in you view's code:

form RegisterForm(forms.Form):

    def __init__(self, *args, **kwargs):
        super(RegisterForm, self).__init__(*args, **kwargs)

A second approach is you clean previous migrations, delete the database and start over the migration process.
