error-handling

问题 This question has been asked before, but the code they answer doesn't apply to me. I want to check when two rectangles collide in my game, and for the circle, I put a rectangle behind the circle(it's colored black). However, when I run, I get an error saying the rectangle needs to have a rect attribute. Here is my code: clock = pygame.time.Clock() pygame.init() change = False screen = pygame.display.set_mode((400, 300)) done = False x = 100 y = 30 bound = False while not done: for event in

问题 Im moving my project to Combine from RxSwift I have a logic where I want publisher to emit event every time I click button. Acrually clicking button executed pushMe.send() pushMe .print("Debug") .flatMap { (res) -> AnyPublisher<Bool, Error> in return Future<Bool, Error>.init { closure in closure(.failure(Errors.validationFail)) }.eraseToAnyPublisher() } .sink(receiveCompletion: { completion in print("Completion received") }, receiveValue: { value in print("Value = \(value)") }) .store(in:

问题 I've got a package which loops through a queue table. For each row to be done, it tries to download data. This is implemented using a Loop container. There are other executables outside the loop - logging, connecting to the remote service etc. I'm having trouble with error handling. What I want to happen is: Any error within the loop container should update the queue table, to say "nope, couldn't download this one" (also some other error logging, but details not important). Then carry on to

问题 so recently, one of my higher-up coworkers stopped working at my job. Due to this, I'm left with some of his responsibilities. Our server is used by one university over here, so to make requests (i. e. a student pays one of his monthly payments) we use a SOAP service to do stuff ( https://api.uregional.net/zoap/uregional/server ). As you can see, the site displays a "Whoops, looks like something went wrong." message when it's loaded. Going into the server logs, I get this error a lot of times

问题 I am sending the request via AJAX to the server. I want to send the response to the AJAX call back whenever an error occurs. So for that in callback function I am writing this return code inside the error block. res.end('{"msg" : "Some error occurred", "status" : 700}'); And with status I am throwing an alert on UI with this message. But whenever the code fails or some errors occurs the console do writes the console error in console but also the server stops and failed to reload the page
