Ruby on Rails, nested parameters permition

Question

i'm trying to save in my database some informations in a model, that have another model, like so:

class Saloon < ApplicationRecord    
   has_many :saloon_address

   accepts_nested_attributes_for :saloon_address
end

and it has addresses:

class SaloonAddress < ApplicationRecord
    belongs_to :saloon
end

and this is my view:

<%= form_with scope: :saloon, local: true, :url => "/saloon" do |form| %>
    <p>
        <%= form.label :name %><br>
        <%= form.text_field :name %>
    </p>

    <p>
        <%= form.label :specialty %><br>
        <%= form.text_field :specialty %>
    </p>

    <p>
        <%= form.label :services %><br>
        <%= form.text_field :services %>
    </p>

    <p>
        <%= form.label :telephone %><br>
        <%= form.text_field :telephone %>
    </p>

    <p>
        <%= form.label :online %><br>
        <%= form.check_box :online %>
    </p>

    <%= form.fields_for :saloon_address do |address| %>
        <p>
            <%= address.label :zip_code %><br>
            <%= address.text_field :zip_code %>
        </p>
        <p>
            <%= address.label :street %><br>
            <%= address.text_field :street %>
        </p>
        <p>
            <%= address.label :complement %><br>
            <%= address.text_field :complement %>
        </p>
        <p>
            <%= address.label :number %><br>
            <%= address.text_field :number %>
        </p>
        <p>
            <%= address.label :city %><br>
            <%= address.text_field :city %>
        </p>
        <p>
            <%= address.label :state %><br>
            <%= address.text_field :state %>
        </p>
        <p>
            <%= address.label :zip_code %><br>
            <%= address.text_field :zip_code %>
        </p>
    <% end %>

    <p>
        <%= form.submit %>
    </p>
 <% end %>

and my controller:

class SaloonController < ApplicationController
    def new
    end

    def show
        @saloon = Saloon.find params[:id]
    end

    def index
        @saloons = Saloon.all
    end

    def create
        @saloon = Saloon.create(saloon_params)
        redirect_to @saloon
    end

    private 

    def saloon_params
        params.require(:saloon).permit(:name, :specialty, :online, :services, :average_price, :telephone,
            saloon_address_attributes: [:saloon_id, :street, :complement, :number, :city, :state, :zip_code, :latitude, :longitude])
    end
end

but when i try to save, i always get the message:

Unpermitted parameter: :saloon_addresss

any ideias of what is happening?

I've searched and tried so many different ways to permit, but i couldn't achieve it.

Update

I've done like the first answer:

class Saloon < ApplicationRecord    
    has_many :saloon_addresses

    accepts_nested_attributes_for :saloon_addresses
end

But now i'm getting this error:

Your has_many call at the top of your Saloon class should pluralize saloon_address like so:

class Saloon < ApplicationRecord    
   has_many :saloon_addresses

   accepts_nested_attributes_for :saloon_address
end

Likewise, your attributes in the params should be pluralized:

def saloon_params
  params.require(:saloon).permit(:name, :specialty, :online, :services, :average_price, :telephone, saloon_addresses_attributes: [:saloon_id, :street, :complement, :number, :city, :state, :zip_code, :latitude, :longitude])
end

Lastly I don't know if this was just a typing error when you wrote the question, but saloon_address appears to be mispelled in the error (extra s). That would be an issue if you have mistyped the model like that somewhere in the code.

Unpermitted parameter: :saloon_addresss
