When we deploy the project on server, Then sometimes the public folder want's the permission. For that we can give the permission from Rails.Creating dir or folder with permission ;-
FileUtils.mkdir 'csv_imported', :mode => 0777
Give the permission of created dir or folder :-
FileUtils.chmod(0777, "csv_imported")
Delete the Directory:-
FileUtils.rm_rf('csv_imported')
Give the permission of particular files :-
File.chmod(0777, path)
Join the folder with root directory :-
csv_folder = Rails.root.join('csv_imported')
Create random csv files :-
csv_name = SecureRandom.urlsafe_base64 + ".csv"
Rename the file :-
File.rename("rohit.csv", csv_folder + csv_name )
