my question is a little complicated, I am building a trip-related web application where users can book trips. So I have made a function that increases the number of travelers as the user clicks the + sign. when this function is called it changes the state and another function gets triggered that displays the form to fill in the traveler details. Now this form is rendered according to the number of travelers traveling. how can I set that data in an array of objects?

here's a screenshot guide:

I want the data to be in the state like this:

I am working on a CSV data Sheet and want to parse and filter the data out it, While working on a code I found a similar code someone has asked on SO POST there and the author having almost the same H/W data as I see that related to HPE H/W where I have some data and columns are different.

I am trying to create a system for domain modelling in typescript, influenced strongly by Scott Wlaschin's Domain Modelling Made Functional which is based on F#.

I am having trouble finding the correct way to handle the passing around of generic properties, so that a generic object type can specify a property as being of some form of another generic type with out forcing resolution immediately. Very hard to explain in text so here is a code example of roughly the kind of thing I am trying to achieve:

I'm trying to use PXDBScalar to bring in a boolean attribute from the Sales Order user defined fields tab to the Shipment screen.

I found another stack overflow post that helped with the creation of the SOOrderKvExt DAC, and I am able to retrieve the value of the valueNumeric (decimal) field via my PXDBScalar attribute, but I cannot find a way to convert the value to a bool so it properly displays as a checkbox on the screen. I tried setting the data type for my unbound field to bool, but got a data type conversion error. I also tried leaving the field as a decimal and just changing the control type on the screen, but it always displays as checked regardless of the value. Any idea how I can convert the decimal value to a bool in the PXDBScalar attribute or another solution?

Code snippets provided below.

I am reading The Art of Multiprocessor Programming, 2ed and I noticed the following pattern is used to read several Atomic* fields:

I have a problem with seeding data into an EF Core DB. The data consists of movies that have a Person object as a relation for their director. The relation works on the basis that a movie should have one director and each director entity in the DB has one directed movie (not ideal but besides the point). The problem arises when I try to seed the initial data in the DB. Since I'm seeding both the movies and the directors, I can't know the IDs of the entities beforehand and I need to be able to search the context for a director with a given name before creating a movie that has a relation to it.

For example:

This is the seeding of the people (directors)

I want to use loadStrings to load data into a csv file , then draw the corresponding 2D shape. Group 1 is ellipse,group 2 is triangle, group 3 is rect, group 4 is parallelogram, and group 0 is other rect. However, my code cannot display the corresponding shape.They don’t displaye any shapes, and there are no errors in my code. One more question, is there any way to display their names under each corresponding graph?

I have been fascinated with Scott WLaschin's Railway Oriented Programming model of handling exceptions: have a side channel, where all the bad stuff will be processed, and keep the good stuff on the main track. Picture below:

A common pattern that comes up in daily code is like :

• Have a list of data
• Validate each one of them
• The validation can throw exceptions

How to do this in a way that resembles the railway-oriented model discussed above.
