One way would be to just process the uploaded-file data from the
request as needed and not worry about saving or doing anything else
with the tmp-saved uploaded-file itself, something like:
### in ./app/models/uploadable_file.rb
class UploadableFile
### for use in testing:
def initialize(fname, contents)
@fname = fname
@contents = contents
end
def original_filename
return @fname
end
def read
return @contents
end
### class meths:
def self.parse(upfile)
return nil if upfile.blank? or not (upfile.respond_to?
('original_filename')\
and upfile.respond_to?('read'))
orig_fname = upfile.original_filename
contents = upfile.read
# parse/process contents ....
end
end
Then just call that class meth in your controller to parse the
uploaded file for an example file form element of name "upfile":
### in some controller meth that handles that multipart/form-data
form:
...
parsed_contents = UploadableFile.parse(params[:upfile])
# check results ....
