My models are as follows (I am using the ForeignKey

QUESTION
I'm a newbie to python so please bear with me. I was making a class that contains the make, model, and fuel of a car and was experimenting with the set and get methods to try and learn their use. The issue I'm running into is when I try to update my tank
attribute by running my setFuel
method and print out the updated fuel integer I get the error tank is not defined
even though I defined it all the way above. Why is this occurring and how can I fix it?
I added comments all over my code to explain what I tried to do to help you understand my code. Any help is appreciated thanks in advance.
...ANSWER
Answered 2021-Apr-26 at 01:38You need myCar.setFuel(myCar.tank-7)
and yourCar.setFuel(yourCar.tank-5)
. You might consider adding a useFuel
method to make that easier.

I want to display all cars that were manucfactured after 1997.
How can it be done using nothing than queries?
These are the predicates
...ANSWER
Answered 2021-Apr-13 at 00:32Your problem is that Prolog does not evaluate arguments inside queries (the procedure you are querying may evaluate them though, but is not what happens in your fact-based source).
So you are passing the term (X@>1997)
as the last argument to car/6
which will not unify with any fact.
You may instead use a free variable to query every car and then constrain the value it is bound to:

ANSWER
Answered 2020-Sep-18 at 01:55If I get you right, you are asking for an “index organized table” (or index organized materialized view in that case), that is a table that is really an index. Then you wouldn't have to waste twice the storage, once for the table that you never use, and once for the index, on which you want to perform index-only scans.
The answer is that such “index organized tables” don't exist in PostgreSQL.
