Hello list,

Some time back I remember discussion of a tool (I think it pre-dates  
engines) that let you quickly/easily deploy multiple instances of a  
single Rails app onto a single server. If, for example, you had  
multiple customers that wanted to run the same application, but with  
e.g. different logos and possibly slightly different rulesets, this  
tool could make a “clone” of an application and let you override the  
core views/controllers/models if and where you needed to do so.

I’ve completely forgotten the name of this tool, and searching a few  
possible keywords in Google hasn’t been enlightening.

Could someone please tell me what this tool is called, as I’ve got a  
possible use for it?

Thanks in advance

Dave M.

Not positive, but was it “productizing?”

I think engines plugin can do the same, and I think it is more easy and  
clean  
for this case (overriding) and when you want to make a module of a  
vertical  
slice of the app. (note that I dont like the other examples of engines  
as  
issolated components which want to fit in all applications)
