ledger | A minimal double-entry accounting system

I am trying to populate data table using SQL query from MySQL/MariaDB, to display it as Trial Balance for a report.

My DB engine is MariaDB 10.4.19

For this instance.. I have 2 tables.

1. Journal (Contains the transactions) and

Could anyone suggest how to go about creating a nested resolver to show an array of objects that are held in a parent object through graphql.

In this case, my schema.prisma file has two models GiftCard and Transaction where each GiftCard has a ledger (array of transactions):

Am starting off in blockchain development using the book Mastering Blockchain - A deep dive into distributed ledgers, consensus protocols, smart contracts, DApps, cryptocurrencies, Ethereum,

Am using WSL with geth version 1.10.9.

I have two files, a master file and a new data file. The new data file is provided on a daily basis and contains the most up-to-date data. This can include duplicate rows already present in the master file, changed rows with some new values, and brand new rows.

How can I quickly get the master file updated with all changed/new rows?

Example of desired output:

Master File Contents:

I have a ledger with a bunch of expenses listed by date, category, and amount. Expenses ledger

Separately I have an analytics sheet for one category, "Gas". I want the analytics sheet to show total gas expenditures month by month without having to update anything other than the ledger. I can get a list of unique months with this formula:
=UNIQUE(ARRAYFORMULA(DATE(YEAR('Main Ledger'!A2:A), MONTH('Main Ledger'!A2:A), 1)))
This populates the months the way I want, and the list will automatically grow with the ledger. I put these in column A.

For each month, I want to compare every entry in the ledger against the date in column A and the category "Gas". I can do that for a single month with the following formula in column B:

=ArrayFormula(SUMIFS('Main Ledger'!D$2:D,MONTH('Main Ledger'!A$2:A),MONTH(A2),YEAR('Main Ledger'!A$2:A),YEAR(A2),'Main Ledger'!F$2:F,"Gas"))

Gasoline analytics

Because I have to use arrayformula to make the date comparison on the ledger, I'm having trouble figuring out how to then use arrayformula to automatically apply this monster formula to all of column B. As column A grows (automatically because of UNIQUE, I want column B to grow too.

I do not want to prepopulate column B and have a bunch of zeroes lying around, mainly because I will be using columns A and B to populate a chart.

I'm pretty sure I have some synthax error in here, but i can't find it.

I wrote this little script here to find some Files in a Folder - I want all the Filepaths that don't have some of the terms in the $excludeList in there but my Contains-Function always returns $true. And when I enable the Write-Output-Line, it also, always sais $true

I've hit a challenge with Sankey diagrams for my personal accounting app. The issue is that the Sankey, generated using Google Charts, won't render if the cash moves in a circle, eg from Ledger A to Ledger B to C and back to A.

The script needs needs an extra step that evaluates the data and if there's a circular movement then it should break that circle by removing the link with the lowest value.

The code starts with a dictionary of dictionaries which contains the amount of cash that's moving between each possible pair of ledgers. Zeros mean there's no cash moving between the two ledgers. This dictionary of dictionaries should be evaluated and circles broken.

Below is some code based on what @JacobDavis response. It does succeed in finding circles but not always. In the example below you can see that Ledger A leads to B. But B leads to both C and D. The code only checks C and thus misses the cycle caused by D.

The code doesn't yet try to break the cycle by removing a link. Trying to get it to identify cycles first.

Input is 2 pandas Dataframe df1 & df2

df1

Models.py- In Hiring Model class Driver field is OneToOneField, how to fetch data from that, i did not find any proper solution how to work with OneToOneField relation, please help me out
