Method create and destroy doesn't work : ruby on rails - ruby-on-rails

Question

I am beginner on coding and on Ruby on rails.
I start to code an app to reference my favorite restaurants.
I start coding my action on my Restaurant Controller and the action Index, Show and Update work.
But I don't understand why my method create and destroy don't work.
Data base : schema.rb :
create_table "restaurants", force: :cascade do |t|
t.string "name"
t.string "price"
t.string "address"
t.string "category"
t.string "website"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.bigint "user_id"
t.index ["user_id"], name: "index_restaurants_on_user_id"
end
Model : restaurant.rb :
class Restaurant < ApplicationRecord
belongs_to :user
CATEGORY = ['Gourmand', 'Healthy', 'Asiatique', 'Italien', 'Cuisine du monde', 'Traditionel',
'Festive', 'Chic', 'Populaire', 'Fast-food', 'Casher', 'Halal', 'Vegan/Végétarien']
PRICE = ['€', '€€', '€€€', '€€€€']
validates :name, presence: true
validates :address, presence: true
validates :price, inclusion: { in: Restaurant::PRICE }, presence: true
validates :category, inclusion: { in: Restaurant::CATEGORY }, presence: true
end
Controller : restaurants_controller.rb
class RestaurantsController < ApplicationController
skip_before_action :authenticate_user!
before_action :set_restaurant, only: [:show, :edit, :update, :destroy]
def index
#restaurant = Restaurant.all
end
def show
end
def new
#restaurant = Restaurant.new
end
def create
#restaurant = Restaurant.new(restaurant_params)
#restaurant.save!
redirect_to restaurants_path(#restaurant), notice: 'new add'
# if #restaurant.save
# redirect_to restaurants_path(#restaurant), notice: 'New restaurant added'
# else
# render :new, status: :unprocessable_entity
# end
end
def edit
end
def update
#restaurant.update(restaurant_params)
redirect_to restaurant_path(#restaurant), notice: 'Restaurant was successfully updated.'
end
def destroy
#restaurant.destroy
redirect_to restaurants_path, status: :see_other
end
private
def restaurant_params
params.require(:restaurant).permit(
:name,
:address,
:category,
:website,
:price
)
end
def set_restaurant
#restaurant = Restaurant.find(params[:id])
end
end
View new : new.html.erb :
<h1>Add a new restaurant </h1>
<%= render 'restaurants/form', restaurant: #restaurant %>
View simple form : _form.html.erb
<%= simple_form_for(restaurant) do |f| %>
<%= f.input :name %>
<%= f.input :address %>
<%= f.input :category, collection: Restaurant::CATEGORY%>
<%= f.input :price, collection:Restaurant::PRICE %>
<%= f.input :website%>
<%= f.submit "#{ restaurant.persisted? ? 'Update' : 'Create' } Restaurant" %>
<%#= link_to 'Back to restaurant', restaurants_path %>
<% end %>
I add Devise Gems by the way but I skip the authentification with a :
skip_before_action :authenticate_user!
on my Restaurant Controller so it does not come from Devise.
Thank you :)
I check on my rails console : no restaurants created
When I put a 'raise' in the action 'create' just before my #restaurant.save, I can see on the params all the informations I added on my form.
But I don't know why it doesn't save my information and don't create the restaurant.
