Code to use in Ruby on Rails:
@files = Dir.glob("path-of-directory/*")
you can check whether any files are there or not ? by the below code,
@total_files = @files.size
Here, you will get all files and folders of the specified directory
If you want only files, then you can use below command,
@files = Dir.glob("path-of-directory/*.*")
Ok. now you can get files names by below code:
for file in @files
puts file
end
If you want random file name and it's extension from @files, then
file_name = @files[rand(999)%@files.size]
ext = file_name[file_name.index('.')+1, file_name.length]
This is the best way I have found for pulling files from a directory and listing them in an array.
