Ruby на Rails 6 jquery и ajax Dynami c форма CRUD

/ 20 января 2020

У меня проблема в Rails 6. У меня есть 3 модели пользователя, персонажа и способности, которые связаны между собой: у пользователя может быть много персонажей, персонаж принадлежит пользователю, персонаж может иметь много способностей, способность принадлежит персонажу. Моя цель - добавить jquery и ajax, чтобы я мог создавать, изменять или удалять способности персонажей со страницы показа персонажей. Вот мой abilities_controller.rb: 

class AbilitiesController < ApplicationController
      def index
        @abilities = Ability.all
      end

      def show
      end

      def new
        @ability = Ability.new
      end

      def edit
      end


      def create
        @character = Character.find(params[:character_id])
        @ability = @character.ability.build(ability_params)


        respond_to do |format|
          if @ability.save
            format.js
            format.html { redirect_to @ability, notice: 'Ability was successfully created.' }
            format.json { render :show, status: :created, location: @ability }
          else
            format.html { render :new }
            format.json { render json: @ability.errors, status: :unprocessable_entity }
          end
        end
      end

      def update
        respond_to do |format|
          if @ability.update(ability_params)
            format.html { redirect_to @ability, notice: 'Ability was successfully updated.' }
            format.json { render :show, status: :ok, location: @ability }
          else
            format.html { render :edit }
            format.json { render json: @ability.errors, status: :unprocessable_entity }
          end
        end
      end

      def destroy
        @ability.destroy
        respond_to do |format|
          format.html { redirect_to abilities_url, notice: 'Ability was successfully destroyed.' }
          format.json { head :no_content }
        end
      end
      private

      private
      def ability_params
        params.require(:ability).permit(:name, :value, :picture)
      end
    end

Страница показа персонажа:

И для последних символов_controller.rb 

class CharactersController < ApplicationController
  before_action :authenticate_user!, except: [:show, :index]
  before_action :set_character, only: [:show, :edit, :update, :destroy]
  before_action :require_same_user, only: [:edit, :update, :destroy]

  def index
    @characters = Character.order(:name).page(params[:page]).per(3)
  end

  def show
  end

  def new
    @character = Character.new
  end

  def edit

  end

  def create
    @character = Character.new(character_params)
    @character.user = current_user

    if @character.save
      flash[:success] = "Character was created successfully!"
      redirect_to character_path(@character)
    else
      render 'new'
    end
  end

  def update
    if @character.update(character_params)
      flash[:success] = "Character was updated successfully!"
      redirect_to character_path(@character)
    else
      render 'edit'
    end
  end

  def destroy
    @character.destroy
    flash[:danger] = "Character was deleted successfully"
    redirect_to characters_path
  end

  private

    def set_character
      @character = Character.find(params[:id])
    end

    def character_params
      params.require(:character).permit(:name, :image, :description, abilities_attributes: [:id, :_destroy, :character_id, :name, :value, :picture])
    end

    def require_same_user
      if current_user != @character.user
        redirect_to characters_path
      end
    end
end
