Rails 4 no implicit conversion of Symbol into Integer - ruby-on-rails

Question

Have been reading through possible answers to this and can't find anything that will fix it.
I have a quotations table, a products table and a join tables quote_listings
quotation model
has_many :quote_listings
has_many :products, through: :quote_listings
accepts_nested_attributes_for :quote_listings
product model
has_many :quote_listings
has_many :quotations, through: :quote_listings
quote_listing model
belongs_to :product
belongs_to :quotation
quotations_controller
def new
#quotation = Quotation.new
#quotation.quote_listings.build
end
def quotation_params
params.require(:quotation).permit(:id, :reference_number,:quote_date, :note, :client_id, :company_id, :user_id, :quote_listings_attributes[:id, :product_id])
end
quotation _form view
= f.fields_for :quote_listings do |builder|
.field
= builder.collection_select(:product_id, current_user.products, :id, :name, { :prompt => 'Select Product' })
Error: TypeError (no implicit conversion of Symbol into Integer)
When I look in rails panel I see this
{"reference_number":"TG68297","quote_date(1i)":"2016","quote_date(2i)":"1","quote_date(3i)":"27","note":"Notes here","client_id":"6","company_id":"3","user_id":"2","quote_listings_attributes":{"0":{"product_id":"5","id":"1"}}}
I have hit a brick wall on this and can't figure out where I have gone wrong

Answer 1

You have a typo:
update this:
def quotation_params
params.require(:quotation).permit(:id, :reference_number, :quote_date,
:note, :client_id, :company_id, :user_id, :quote_listings_attributes[:id, :product_id])
end
to this:
def quotation_params
params.require(:quotation).permit(:id, :reference_number, :quote_date,
:note, :client_id, :company_id, :user_id, quote_listings_attributes: [:id, :product_id])
end
