Но в написанном файле я получаю только последние путы.Файл удаляет предыдущую информацию и показывает только последнюю.Я хочу показать всю информацию, возвращенную в файле @event, @venue, @date.Я не знаю, как сделать, присоединиться к предыдущему сообщению с текущим сообщением.Кто-нибудь может мне помочь?

Answer 1

Каждый @event, @venue и @data содержит один фрагмент данных. Кажется, вы перезаписываете значения перед сохранением их в файл. Пытаться положить

puts "Writing to file"

Прямо перед строкой f.puts.

Вы, вероятно, увидите, что это происходит после того, как произошла другая обработка. Вы хотите печатать каждый раз, когда вы обновляете 3 значения.

Я бы открыл выходной файл в начале вашего скрипта и либо передал его, либо установил в качестве переменной экземпляра (@file). Затем каждый раз, когда вы делаете путы, также делайте @ file.puts.

Вы также можете сделать @event, ... массивами и вместо того, чтобы назначать им, сделать что-то вроде этого:

#initialization
@output = []
#...
@output.push(line) if line.match(/^Event/)
@output.push(line) if line.match(/^Date/)

Затем распечатайте @events в конце.

Answer 2

У вас неправильный режим открытия для вашего файла

 File.open("YOUR_PATH_TO_FILE", 'w') do |f|
   f.puts @event,@venue,@date
 end

если вы проверите документацию вы увидите

"w"  |  Write-only, truncates existing file
     |  to zero length or creates a new file for writing.

вам нужно a+ или одиниз

Mode |  Meaning
-----+--------------------------------------------------------
"a"  |  Write-only, starts at end of file if file exists,
     |  otherwise creates a new file for writing.
-----+--------------------------------------------------------
"a+" |  Read-write, starts at end of file if file exists,
     |  otherwise creates a new file for reading and
     |  writing.
