Re: [Rails] Forcing browser redirects on a Ruby on Rails application

Thanks for the reply Colin. 

We do not know the user ids before hand. They will sign up for the research study, and the admin will decide which users to pair among the ones online. One user may be paired with three to four other users one after another. I want to have the admin control over the process so that we could pair a user with a third online user if one from the original pair got offline and did not return. So the decision about which url to redirect to must be made dynamically. 

Do you think the Table approach would still work in the above scenario? 

I was thinking of building some sort of a polling mechanism (i'm not super clear on how to do that as I am relatively new) where the browsers contact the server to confirm their online status. However I was confused as to how I could redirect two browsers to a common url.

I found this on stack-overflow: http://stackoverflow.com/questions/199099/how-to-manage-a-redirect-request-after-a-jquery-ajax-call/1534662#1534662 

Which seems to be a promising solution. What do you think?

You could save the redirect requirement in a table in the database,
with an appropriate relationship with the user, then use a before
filter in the controller to check whether a redirect is required and
do it.
