Rails ActionController::UnpermittedParameters found unpermitted parameter when param present - ruby-on-rails

Question

I have the following form that is trying to load in checkboxes with labels all regions and allow those to be saved to logos on the Logo form page.
= tb_form_for [:admin, #logo],
remote: true,
data: { errors: :inline, success: admin_logos_path } do |f|
= tb_form_errors(f.object, :base)
= f.tb_text_field :name
= f.tb_check_box :home_page, class: 'checkmark'
= f.tb_file_field :logo_photo
= image_tag #logo.logo_photo, style: 'padding-left: 180px; padding-bottom: 20px;' if #logo.logo_photo.present?
= f.collection_check_boxes :region_id, Region.all, :id, :name, checked: Region.all.map(&:id) do |x|
div
= x.check_box
= x.label
= f.tb_save_buttons('Logo', admin_logos_path)
The page loads properly but the error cames with saving I end up with
ActionController::UnpermittedParameters (found unpermitted parameter: :region_id)
Cool so I check my LogosController and I have the following:
class LogosController < ApplicationController
before_action :load_logo, only: [:show, :edit, :update, :destroy]
def create
#logo = Logo.new(logo_params)
flash[:notice] = 'Created' if #logo.save
respond_with #logo
end
def edit
respond_with #logo
end
def update
flash[:notice] = 'Updated' if #logo.update_attributes(logo_params)
respond_with #logo
end
private
def logo_params
params.require(:logo).permit(:name, :home_page, :user, :region, :logo_photo, :region_id, :user_id)
end
end
I've tried several variations on the first argument being passed:
#logo.region results in
found unpermitted parameter: :Region::ActiveRecord_Associations_CollectionProxy:0x00007f81a79a81e0>
:region results in
found unpermitted parameter: :region
#logo results in
found unpermitted parameter: :Logo:0x00007f81a34da8
#logo.region_id ends up with a Bad Request
expected Array (got Rack::QueryParser::Params) for param `logo'
How do I accurately hit this?

Answer 1

Change ":region" by ":region_id" on "logo_params" like this
params.require(:logo).permit(:name, :home_page, :user, :region_id, :logo_photo,:user_id)
