Railsのファイル入出力に関して

More than 5 years have passed since last update.

単純にrubyでのファイル入出力を応用します

まずはファイルへの書き込み

f = File.open('file.txt', 'w') # wは書き込み権限
f.puts test
f.close

デフォルトだと
application/
/app
/db
/config
/file.txt

の位置に出来るので,
好みで

f = File.open('./app/assets/file.txt', 'w')

のようにするのがオススメ

読み込みは
wを
r
にするだけ!
