cinema | Website public movie information and ticket sales | REST library

I want to create a trigger which will check if my showtime with Cinema Hall Id exist or not. This will prevent me from booking one Cinema hall at two same Showtimes. Secondly in this trigger I am also checking if the showtime I am assigning to movie lies in movie release and last date range or not. But I don't know why none of the statement is working.

I'm a beginner in python so I have this program where it classifies tweets into different categories (sport,sante, culture...) using keywords and I would like to copy-paste every line of the JSON file that belongs to a certain category into a file named text1 and I did the following : but I guess I did it the wrong way since I keep receiving the same error please any suggestion on how to solve this problem!

I have this DB for movie management in cinemas: FILM (ID_FILM, TITLE, DIRECTOR_NAME, PRODUCTION-BUDGET, RELEASE-DATE) SCREENING(ID_SCREEN, ID_FILM*, SCREEN_DATE, ROOM, City) SEEN (ID_SEEN, SPECTATOR_NAME, ID_SCREEN*, TICKET-PRICE).

I need to complete the Film type with the MySpectators method returning the whole (without duplicates) of its spectators. This is what I wrote for the signature and the body of this method :

I am working with javaFX on inteliJ using javafx-sdk-11.0.2. I made a GUI for a cinema and when I want to run it on inteliJ, everything works fine. But when I create a jar file and I execute it then everything works fine again until I click on a button for switching from scene.

That is what I get when clicking on the button. Note that not all buttons have the same problem. I have some buttons that work fine while I am using the same code everywhere.

I am facing an error using JEST with Express while I execute my test with npm run test.

I have a component that instantiates a few classes from the Tone.js library (e.g audio players and filters) and defines a few functions acting on these objects, which are used as callbacks in a set of UI-rendered buttons (see relevant code below).

Two of these buttons are supposed to toggle the boolean state is3D using the useState hook (in the updateSpatial function) in order to enable/disable one of these buttons. However, this update obviously causes the component to re-render entirely, thus re-instantiating my classes, which prevent the defined functions to work afterwards.

In contrast, I also tried the useRef hook, which allows for is3D update without re-rendering, but the button's disabled state is not updated as the component does not re-render.

Is there a pattern that fits with this situation? My next attempts include using HOC, Context, or Redux, but I'm not sure this is the most straighforward. Thanks!

Ive got a problem since i realized that I break the DRY(Dont repeat yourself) rule. So basically I have 2 modules(movies, cinemas) and few methods in them which look the same but use their module' state. Example: Movies has 'movies' state. Cinemas has 'cinemas' state.

Below is my sample schema.

I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:

first_job <- function(x) tail(x[!is.na(x)], 1)

first_job <- apply(data, 1, first_job)
