Instance Method Details

#content_security_policy(enabled = true, **options, &block) ⇒ Object

Overrides parts of the globally configured ‘Content-Security-Policy` header:

class PostsController < ApplicationController
  content_security_policy do |policy|
    policy.base_uri "https://www.example.com"
  end
end

Options can be passed similar to ‘before_action`. For example, pass `only: :index` to override the header on the index action only:

class PostsController < ApplicationController
  content_security_policy(only: :index) do |policy|
    policy.default_src :self, :https
  end
end

Pass ‘false` to remove the `Content-Security-Policy` header:

class PostsController < ApplicationController
  content_security_policy false, only: :index
end
