to_path=params[:file_name]
to_path[“queue/”]=""
FileUtils.mv “#{from_path}”, “#{to_path}”

end

request parameters:

{“file_name”=>“recordings/WCR-20160409.mp3”,
“file_type”=>“to_be_moved”,
“page”=>“list_directory”}

i get this error:

Errno::ENOENT in RecordingsController#move_file No such file or
directory @
sys_fail2 - (recordings/WCR-20160409.mp3, recordings/WCR-20160409.mp3)

around … FileUtils.mv “#{from_path}”, “#{to_path}”

I’m trying to move the file from the recordings/queue/ direcotry up a
level
to recordings/ I don’t really understand the error it looks like it’s
taking both arguments, from_path and to_path and treating them as a
combined first argument Anyone?

Have you put a debug print in to check what from_path and to_path are
set to?

params[:file_name], from_path, and to_path all point to the same
object. to verify, check their #object_id.

so if you modify to_path, you also modify the other two. try #dup to
copy an object.

No because this action doesn’t print, it moves the file and redirects

the = assignment operator assigns the values from the right side operand
to
the left side, it doesn’t change the value of other variables, i dunno
what you mean and i dunno what #dup is ~ fugee

Because, as botp pointed out, they are referencing (pointing to) the
same object in memory.
Use
to_path = some function of params[…]
to avoid the problem. In a previous post you said you did not know
what dup does. Perhaps you should find out.

Like what inconsequential function of params[:file_name] could i use? i
tried params[:file_name].to_s but it had no affect
