I have the views of devise in views/users, but I have one layout for all app in aplication.html.erb, but the devise i dont want to renderize with this layout, so I create a sessions controller and add this line code render "layouts/sessions" where i create a layout special for login with the form default of devise and I will customize. But when I add the authentication in application_controller:

before_action :authenticate_user!

I have a form that has fields from two different tables, the Patients table and the Addresses table. Please make a search field to use only one patient (Patient) and return his data, up to the fields in the patient table and return the right data when adding a field to present a street in case of a street and it will be the following error:

I'm starting a project with rails 5 and the first thing I did was add the bootstrap to rails 5. I added the gem and imported it into application.scss. I generated a devise Admin and the bootstrap worked, but then I generated a controller with the following command Rails generate backend / dashboard index. On this backend dashboard my bootstrap is not working.

here my application.scss

/
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib / assets / stylesheets, or any plugin's
 * vendor / assets / stylesheets directory can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any other CSS / SCSS
 * files in this directory. Styles in this file should be added after the last require_ * statement.
 * It is generally better to create a new file per style scope.
 *
 * /

// Custom bootstrap variables must be set or imported * before * bootstrap.
@import "bootstrap";

return this error now

I am making a patient control system where I have the following tables that I need to list and present the data on the show.html.erb of patients.

I created a patient scaffold with the following data

  t.string :cpf
  t.string :name
  t.string :telephone
  t.string :rg
  t.date :birth
  t.string :mother

and a model address with the following data

t.string :street
t.integer :cep
t.string :city
t.string :state
t.string :neighborhood

the ratio is 1 to 1 (belongs to) my question is how do i do all this relation and how do i present the data from the addresses table in the patients show.html.erb.
