I have a store setup that has multiple arrays

I'm trying to search all arrays at once, via a textfield.

I can get this done, by calling a selector function on keyup, that filters the 4 arrays and pushes to a new array.

I've thought about merging all the arrays to one array before filtering, but I want to keep the results separate, as they are going to be displayed in categories.

Just trying to see if I can streamline the performance at all and if there's a more concise way of doing this, in case I need to do something similar with larger arrays.

my textField function:

I have an array of objects each with a groupName key/value and then an item key with an array of objects as it's value.

I'm trying to use .reduce() with a forEach to iterate over the main array and merge all of the item values into a new Object with a single groupName and an items array containing all the original item values.

Every time I run the function I only get back the first value and I'm trying to figure out what I'm doing wrong.

Current Function:

I am currently creating class diagrams in UML for a movie test domain. I would like to know if I am doing it right. Well, I have two alternatives (the first version in the first picture, the second in the second - I think the first one is better). I'm wondering if I've established the so-called "relationship owner" correctly, that is, from which class to which direction the relationships go. I also don't know if I didn't get multiplicity wrong (one to one, one to many etc.).

So on my domain I would like to have movies of course, the actors starring in those movies and directors. I wonder if the class name "Character" is good in this case, because I mean all the characters that take part in a movie - it can be director, actor but also for example "Batman". Maybe I should make a distinction here between "Movie Character" and then "Human", "Monster", whatever. But I don't know how to do it elegantly, will I then inherit from the Character class? I'm also wondering if I shouldn't put classes like City or Country together in one class called Address - but I wanted the classes to take attributes like in this case, that one is Master and the other is detail - and the relationship set in the right direction. I use only relations such as Inheritance and Dependency, I do not know if I should change something in this case.

Thanks in advance for any suggestions or advice!

I am trying to build a cinema app with flutter. The structure is as follows:

• in each city there are a bunch of cinemas
• in a cinema there are a bunch of showrooms(salle in french)
• in a showroom(salle in french) there are five display sessions or projections, these projections are of the same film.

because the projections are of the same movie (a showroom displays the same movie in different time(e.g projections) by design), when I click on any of the projections in a showroom I should have the same posture of the same film, not a different posture in each projection.

However I get a different film posture in each projection, and I don't know what is causing this.

I am using a rest api that I created with Spring, and I am certain that the problem is not from my back-end because I am using it in an angular web app and it's working perfectly.

This is a layout of my application

this is what happened when I click on two projection of the same showroom( notice that the posture changes when it shouldn't.

and here is the code of the showroom page (salles-page.dart)

I have a project created with NextJS and ReactJS. I've installed Tailwind CSS and used in some components which are located in 'components' folder.

I created one more component in same 'components' folder, named 'Thumbnail.js'. I wanted to use h-2 truncate p-2 in a p tag inside of 'Thumbnail'. They didn't show any effect on the components. And can't even see these class names in Chrome debugger.

In the same 'Thumbnail' component I've used transform hover:scale and interestingly it worked.

I am basically fetching data from an movie api (I use React). Some movies have 1 genre and some have 2 or more.

When a movie have 2 or more genres, I have no problems rendering them because I only want to render 2 genres (array 0 and 1), however when the movie have only 1 genre I get errors when rendering the 2nd genre because there are no data in it.

Is there a way to make a condition so that when there is no data from the 2nd genre it will not render anything and will only render the 1st genre?

Here is the code

I am really new to React JS. I am making a small project that has a table with movies in it. In the top it shows how many movies are there.

My problem is that this.setState() is not working. It is showing an error numberOfMovies is not defined.

While deleting and adding works fine, when I update the Parent collection of child entities, the foreign keys on child records are simply set to null. I'd like them to be completely removed from the database.

So I've been trying Cascade.All, Cascade.DeleteOrphans, Cascade.All.Include(Cascade.DeleteOrphans) and nothing seems to work.

If I set Inverse to true on the parent but it causes the child records to not get updated at all.

Here's my code:

Am a self learning developer, now learning Java. I have learned that to use method reference for a Functional Interface, the signature of the method we referring must match the signature of the abstract method inside that functional interface.

But While learning Comparator, found that "Comparator.comparing()" method takes Function interface and returns a Comparator. I know that the abstract method of Function interface must take a argument and return a value.

but I can able to pass any method(as method reference) that partially (not fully) matches the signature of Function interface to the comparing() method of Comparator.

for example consider the below example.
