I would advise against that method. The view should not be making decisions based on where it came from, it should be displaying what it is told to display. If a particular action (create in this case) requires something particular of a view then the action should tell the view what to do by setting an @variable. The view should not be saying 'I see that I came from the create action therefore I will display this', it should be saying 'I see that this variable contains this data so I will display the data as requested'. @Mauro, what is the difference you wish to see in the view based on where it came from?
