Last updated at 2022-08-21Posted at 2019-04-16

Premise

Create a Rails model.

 rails generate model book title:string author:string

Make data.

 rake db:migrate

Create resources for ActiveAdmin.

 rails generate active_admin:resource book

Start the Rails server.

 rails server

And when trying to register new data from a browser (http: // localhost: 3000 / admin / books / new). . .

Exception occurred!

ActiveModel :: ForbiddenAttributesError in Admin :: BooksController # create

I can not create.

After that, specify permit_params in the resource file of ActiveAdmin! only this.

 ActiveAdmin.register Book do permit_params :title, :author end
