Ruby how to write to Tempfile
You're going to want to close the temp file after writing to it. Just add a t.close to the end. I bet the file has buffered output.
Try this run t.rewind before read
require 'tempfile't = Tempfile.new("test_temp")t << "Test data"t.write("test data") # => 9IO.read t.path # => ""t.rewindIO.read t.path # => "Test datatest data"
close or rewind will actually write out content to file. And you may want to delete it after using:
file = Tempfile.new('test_temp')begin file.write <<~FILE Test data test data FILE file.close puts IO.read(file.path) #=> Test data\ntestdata\nensure file.deleteend
