Ruby on Rails

Sorry but there were too many typos Here is a corrected verion

I need a progress indicator that shows the progress of a parser that
also writes the progress state to a db. I have several other examples
of the need
of informing the users of progress of processes that takes some time.

I will not put the parser in a background process, as I think there
should be a more simple solution, considering all the code that needs
a background process for this solution to work i my situation with
many progress indicators

Could one use a remote ajax call to start the e.g the parser and then
call an Ajax function
at the onBefore call back, that asks the server about the progress as
defined in the db

Is this a possible approach?
If so what Ajax function should be used to ask the server db about
progress?
Are there other better solutions?
