[myexperiment-hackers] virtual_hosts

[Finn Bacall]

Hi guys,

I'm planning on changing how myexperiment chooses what page layout to 
use. At the moment, this is decided before a request is passed through 
to a controller action (by looking at the request URL, referrer, etc.).

For e-LICO, I'm adding in an option (a small checkbox) that will be 
displayed in the "sharing" section of the workflow creation/update form, 
that allows a user to indicate that they want their workflow to be 
rendered in a custom layout (like how the e-LICO group page looks at the 
moment).

The issue with doing this in the current system, is that I need to 
access to the workflow object to check which layout the user has 
specified to use, and this isn't fetched until the controller action is 
processed. My solution is to create a helper method to choose which 
layout to display, which is called by the view. This ensures the 
controller action has already run and I have access to the workflow object.

Before I do this it would be good to hear any criticisms/suggestions. 
I'd also like to know if there are other "virtual hosts" in-use other 
than e-LICO, as I was considering moving settings purely to do with the 
layout/stylesheet into a different section in the "settings" YAML file.

Cheers,

-Finn
