How to change a Phoenix Project name smoothly?

Questions & Help Questions
1

I use mix phoenix.new paper to create a new project paper.

So all the stuff is called Paper or :paper.

However, I have to define a model called paper. So I have something like defmodule Paper.Paper do.

When I have multiple aliaes, I need to move Paper.paper to the last.

I know I made a “stupid” codename that may interfere with the model name.

So how can I modify all the Paper. stuff and :paper stuff eaisly? Is there a Phoenix mix command to do that?

Thanks!
