instance method

Ruby on Rails edge
Since v6.0.6.1Signature
open(tmpdir: nil, &block)Downloads the blob to a temporary file on disk. If a block is given, the file is automatically closed and unlinked after the block executed. Otherwise the file is returned and you are responsible for closing and unlinking.
The tempfile’s name is prefixed with ActiveStorage- and the blob’s ID. Its extension matches that of the blob.
By default, the tempfile is created in Dir.tmpdir. Pass tmpdir: to create it in a different directory:
blob.open(tmpdir: "/path/to/tmp") do |file|
# ...
end
Raises ActiveStorage::IntegrityError if the downloaded data does not match the blob’s checksum.
Parameters
-
tmpdirkey = nil -
blockblock
