ActiveModel::ForbiddenAttributesError occurs when you try to enter a value in Rails ActiveAdmin.

For the implementation of the basic model admin, we have created a file that can modify ModelName as follows.

ActiveAdmin.register ModelName do
  menu priority: 2, label: 'aaa', parent: 'bbb'
end

It goes well to the editing screen, but when I try to create a new record, ActiveModel::ForbiddenAttributesError occurs.

ActiveModel::ForbiddenAttributesError /Users/@@/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/activemodel-4.2.6/lib/active_model/forbidden_attributes_protection.rb:21:in sanitize_for_mass_assignment' /Users/@@/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/activerecord-4.2.6/lib/active_record/attribute_assignment.rb:33:inassign_attributes'

Why is it like this?

Rails 4 uses strong parameters so if an attribute is not allowed, ActiveModel::ForbiddenAttributesError appears.

Therefore, you must include permit_params in ActiveAdmin.

ActiveAdmin.register ModelName do
  permit_params : attr1, :attr2, :etc//<-- Add this line. 

 // Replace attr1 and attr2 with the actual attribute name. 
end
