How to use phx.gen.auth

Hi, I’m trying to figure out how to use the new phx.gen.auth generator and I have followed through with the commands here:

But I don’t see what I am supposed to do after that. I can create accounts and be logged in, but how do I set pages so that they are behind the authentication wall?

I’ve even looked at Jose’s demo app here:

but I can’t see how it isn’t just a regular Phoenix app named demo?

Look at the router:

github.com

dashbitco/mix_phx_gen_auth_demo/blob/auth/lib/demo_web/router.ex#L45-L52


scope "/", DemoWeb do
  pipe_through [:browser, :require_authenticated_user]

  get "/users/settings", UserSettingsController, :edit
  put "/users/settings/update_password", UserSettingsController, :update_password
  put "/users/settings/update_email", UserSettingsController, :update_email
  get "/users/settings/confirm_email/:token", UserSettingsController, :confirm_email
end

I believe this pull request is relevant too: https://github.com/dashbitco/mix_phx_gen_auth_demo/pull/1

As Jose said, you can find the plug :require_authenticated_user being used in the router file, protecting routes against unauthenticated users. You can find the code of that plug in the controllers, in the (your schema name)Auth module.

What I personally did to see clearly all the code being generated, is creating two new Phoenix projects. On one of them I run the generator. Then I compare the code of both projects with my diff tool, study, and copy code into my project.

I feel quite silly that I missed that, thanks boss.

For anybody else having the same trouble, the auth branch in the demo is the one with the code that shows you how it works.
