Currency exchange dynamic data

Rails
1

Hi Folks,
i want to add a table with some currecny exchange values that i have to
update 2-3 times a day.
the problem is i have to update the file and restart the webserver to
have the change taking effect .

Is there another way to do it on a simple file without having to restart
the webserver ?

any ideas suggetion are welcome.

thanks

Use database to save currency exchange. then you dont need to restart
server.
Or when currency file updated reload it, its looks like you loading it
in environment.rb, use same loader when you update currencies.

Do you mean a table on a web page or a table in the database?

I presume from this that you mean the data is in a file.

One solution is to put the currency data in a table in the database.
Write a rake task to read from the file and update the db and run this
when the file changes. You could just put the update code in
db/seeds.rb and then run rake db:seed (which runs seeds.rb).

If you are updating a table and rendering to a dynamic page you should
not
have to restart the webserver. Otherwise you should provide specific
details
of what you are trying to do and why specifically you have to restart
the
webserver.

Sorry… did not see all the responses, maybe I am going insane or does
gmail sometime not show the thread responses sometimes.

railstutorial.org is a good free to use online tutorial. Forget about
your current project and work right through the tutorial to get the
hang of what it is all about. railsforzombies.org looks fun but I
have not tried it.
Also see the Rails Guides.
seeds.rb is just a file that is executed when you run rake db:seed.
