Can anyone help point me in the right direction on doing the
following?
Say I have a Rails app that deals with photos at photo.website.com,
and I also have a legacy site at www.website.com.
What I would like to do is from a static html page on www.website.com
have a random photo displayed from the photo app.
So, if I put something like this in my static page: <img src="http://
photo.website.com/randompic.jpg" />
would it be possible when a user hits the static page to have it
routed to an action that would pull a random photo and return it to
the static page in the form of an image?
well, i don't know much about your rails app. so i can't tell you how
exactly you should do it. but generally spoken: yes, that should be
possible. actually in exactly the way you proposed.
Create a controller called random, and an action called pic (you can call
these anything, or even use the default index action). In your action,
just pick a random image and serve it back to the browser.
We do something similar, without the randomness to serve images to
external applications.
