`db/main.py` is an *extremely* badly-written script that reads files (`pytania.csv` and `punkty.csv`) published by the Ministry of Infrastructure and imports them into a database
|
|
- `db/pytania.csv` is the `katalog_pytania_egzminacyjne_kandydat__14112024.xlsx` file from [here](https://www.gov.pl/web/infrastruktura/prawo-jazdy), opened in Libreoffice Calc and saved as csv
|
|
- `db/punkty.csv` isn't published by the Ministry, so you have to send a freedom of information request to acquire it; it is processed the same way as `pytania.csv`
|
|
|
|
The database structure is as follows:
|
|
```sql
|
|
CREATE TABLE tasks (
|
|
id integer NOT NULL,
|
|
correct_answer boolean,
|
|
media_url text,
|
|
weight smallint
|
|
);
|
|
|
|
CREATE TABLE questions (
|
|
task_id integer,
|
|
lang character(2),
|
|
text text
|
|
);
|
|
|
|
CREATE TABLE tasks_advanced (
|
|
id integer NOT NULL,
|
|
correct_answer character(1),
|
|
media_url text,
|
|
weight smallint
|
|
);
|
|
|
|
CREATE TABLE questions_advanced (
|
|
task_id integer,
|
|
lang character(2),
|
|
text text,
|
|
answer_a text,
|
|
answer_b text,
|
|
answer_c text
|
|
);
|
|
|
|
CREATE TABLE categories (
|
|
name text,
|
|
task_id integer
|
|
);
|
|
```
|
|
|
|
The basic tasks can be queried like so:
|
|
```sql
|
|
SELECT tasks.correct_answer, tasks.media_url, tasks.weight, questions.text
|
|
FROM tasks
|
|
LEFT JOIN questions ON tasks.id = questions.task_id
|
|
LEFT JOIN categories ON tasks.id = categories.task_id
|
|
WHERE
|
|
categories.name = 'B' AND
|
|
questions.lang = 'PL'
|
|
ORDER BY random()
|
|
LIMIT (20);
|
|
```
|
|
And the advanced tasks like this:
|
|
```sql
|
|
SELECT tasks_advanced.correct_answer, tasks_advanced.media_url, tasks_advanced.weight,
|
|
questions_advanced.text, questions_advanced.answer_a, questions_advanced.answer_b, questions_advanced.answer_c
|
|
FROM tasks_advanced
|
|
LEFT JOIN questions_advanced ON tasks_advanced.id = questions_advanced.task_id
|
|
LEFT JOIN categories ON tasks_advanced.id = categories.task_id
|
|
WHERE
|
|
categories.name = 'B' AND
|
|
questions_advanced.lang = 'PL'
|
|
ORDER BY random()
|
|
LIMIT (20);
|
|
``` |
