I have a class photo. It belongs_to a project.

In my ProjectsController I am creating 2 instance variables:

@displayphoto = Photo.find_by_project_id(params[:id])

...and also

@photo = @project.build_photo


The @displayphoto instance returns a nil object.
However,

@photo = Photo.find_by_project_id(params[:id])

works fine. So evidently it is the name @displayphoto
that is causing the problem.

So I have 2 questions:

1)  Must an instance variable always be the same
     name as the name of the class?
2)  If the above is true,  how can I create 2 separate
     instance variables in my controller for the same class?


Thanks,
