I am being super new to Rails, so, please keep it in mind reading my post.
I am trying to develop a very simple app where I can create a game and assign players to this game.
So far I have a scaffolded game and player resources. I have set has_many :players and has_many: games relationship, for both, - game and player models.
I added form.select in view form (new):
<%= form.label :player_id %>
<%= form.select :player_id, Player.all.collect{|x| [x.name]} %>
What I am trying to achieve is, - I want to be able to add multiple players to the single game. If I paste the same form.select field again it will overwrite first selection and eventually save only one (last) player.
I can, however, replicate this functonality in rails console. with:
g = Game.last
g.players << Player.find(1)
g.players << Player.find(2)
And it works.
Can you advise me on how to do same at FronEnd level? I understand if my approach is completely wrong, then let me know what will be a better one.
Many thanks in advance.
Update 1.
I have very default scaffold controller:
class GamesController < ApplicationController
before_action :set_game, only: [:show, :edit, :update, :destroy]
def index
@games = Game.all
end
def show
end
def new
@game = Game.new
end
def edit
end
def create
@game = Game.new(game_params)
respond_to do |format|
if @game.save
format.html { redirect_to @game, notice: 'Game was successfully created.' }
format.json { render :show, status: :created, location: @game }
else
format.html { render :new }
format.json { render json: @game.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if @game.update(game_params)
format.html { redirect_to @game, notice: 'Game was successfully updated.' }
format.json { render :show, status: :ok, location: @game }
else
format.html { render :edit }
format.json { render json: @game.errors, status: :unprocessable_entity }
end
end
end
def destroy
@game.destroy
respond_to do |format|
format.html { redirect_to games_url, notice: 'Game was successfully destroyed.' }
format.json { head :no_content }
end
end
private
def set_game
@game = Game.find(params[:id])
end
def game_params
params.require(:game).permit(:name, :date, :player_id)
end
end
and my db tables look like this:
class CreatePlayers < ActiveRecord::Migration[5.1]
def change
create_table :players do |t|
t.string :name
t.string :role
t.integer :game_id
t.timestamps
end
end
end
class CreateGames < ActiveRecord::Migration[5.1]
def change
create_table :games do |t|
t.string :name
t.date :date
t.integer :player_id
t.timestamps
end
end
end
Do i need to have action in game controller for it ?
