Methode, die nicht in Tabelle schreibt

Question

Während ich bin, um neues Objekt des Klassenrezepts zu erstellen, werden keine Daten in Richtungsmodelltabelle eingefügt.

Rezept Controller:

class RecipesController < ApplicationController 
    before_action :find_recipe, only:[:show, :edit, :update, :destroy] 
    def index 
     @recipe = Recipe.all.order("created_at DESC") 
    end 

    def show 
    end 

    def new 
     @recipe = Recipe.new 
    end 

    def create 
     @recipe = Recipe.new(recipe_params) 

     if @recipe.save 
      redirect_to @recipe, notice: "Dodano nowy przepis" 
     else 
      render 'new' 
     end 
    end 

    def edit 
    end 

    def update 
     if @recipe.update(recipe_params) 
      redirect_to @recipe 
     else 
      render 'edit' 
     end 
    end 

    def destroy 
     @recipe.destroy 
     redirect_to root_path, notice: "Przepis został usunięty" 
    end 



    private 

    def recipe_params 
     params.require(:recipe).permit(:tittle, :description, :image, :portion, :preparation_time, ingredients_attributes: [:id, :name, :_destroy], directions__attributes: [:id, :step, :_destroy], recipe_ingredients_attributes: [:id, :quantity, :_destroy]) 
    end 

    def find_recipe 
     @recipe = Recipe.find(params[:id]) 
    end 



end 

Rezept Modell:

class Recipe < ApplicationRecord 
    has_many :directions, inverse_of: :recipe 
    has_many :recipe_ingredients 
    has_many :ingredients, through: :recipe_ingredients 

    accepts_nested_attributes_for :ingredients, 
            reject_if: proc { |attributes| attributes['name'].blank? }, 
            allow_destroy: true 
    accepts_nested_attributes_for :directions, 
            reject_if: proc { |attributes| attributes['step'].blank? }, 
            allow_destroy: true 


    validates :tittle, :description, :image, presence: true 
    has_attached_file :image, styles: { :medium => "400x400#" } 
    validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/ 

end 

Richtung Modell:

class Direction < ApplicationRecord 
    belongs_to :recipe, inverse_of: :directions 
end 

Linie von der Konsole über neues Rezept-Objekt erstellen:

Wie Sie oben in DB Query String sehen können, geht Richtung Attribute ohne ID und dies ist wahrscheinlich Hauptgrund. Allerdings ... Ich habe keine Ahnung, wie ich das beheben kann.

Bitte helfen Sie mir, wie ich mit diesem Problem seit einiger Zeit kämpfe.

Answer 1

Es ist wegen Unpermitted parameter: directions_attributes.

directions__attributes extra _ in starken params entfernen.

Innen

def recipe_params 
     params.require(:recipe).permit(:tittle, :description, :image, :portion, :preparation_time, ingredients_attributes: [:id, :name, :_destroy], directions__attributes: [:id, :step, :_destroy], recipe_ingredients_attributes: [:id, :quantity, :_destroy]) 
    end 

Änderung directions_attributes. Es wird funktionieren.
