How to get ActiveAdmin to work with Strong Parameters?
Update to the latest inherited_resources gem and do this in your controller block:
ActiveAdmin.register Blog do #... controller do #... def permitted_params params.permit(:blog => [:name, :description]) # params.permit! # allow all parameters end endend
The documentation now clearly states how to go about Setting up Strong Parameters in Rails 4. See:
The accepted answer did not work for me with resources defined in an engine, so I tracked down the original resource_params in inherited_resources/lib/inherited_resources/base_helpers.rb and came up with this solution which closer mimics that code, and which works with engines:
In config/initializers/active_admin.rb:
ActiveAdmin::ResourceController.class_eval do # Allow ActiveAdmin admins to freely mass-assign when using strong_parameters def resource_params [(params[resource_request_name] || params[resource_instance_name]).try(:permit!) || {}] endend
