使用Ruby on Rails App中的单选按钮在MySQL表中创建记录

Question

I have created a fantasy golf App and I want the user to create an entry in the scores table by selecting golfers by selecting their radio buttons (Pick one golfer from each group basically). Here is a section of the form.

Golfpicks.html

            <% provide(:title, 'Golfers Picks') %>
             <%= form_for Score.new do |f| %>
                <h2>Pool 1</h2>
                <ul class="users">
                <%= field_set_tag do %>
                  <%= render Golfer.where(:golferid => 1) %>
                  <%= f.radio_button :golferidgroup1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 2) %>
                  <%= f.radio_button :golferidgroup1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 3) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 4) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 5) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 6) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 7) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 8) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 9) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 10) %>
                  <%= f.radio_button :golfergroupid1, false, :checked => true %>
                  <% end %>
                </ul>
                <h2>Pool 2</h2>
                <ul class="users">
                <%= field_set_tag do  %>
                  <%= render Golfer.where(:golferid => 11) %>
                  <%= f.radio_button :golferidgroup2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 12) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 13) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 14) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 15) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 16) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 17) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 18) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 19) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                  <%= render Golfer.where(:golferid => 20) %>
                  <%= f.radio_button :golfergroupid2, false, :checked => true %>
                <% end %>
                </ul>
                <% end %>
                </ul> 
                <%= f.submit "Enter my Team", class: "btn btn-primary" %>
            <% end %>   

Here is my scores Helper

        class ScoresController < ApplicationController

              def index
                @scores = Score.paginate(page: params[:page])
              end

                 def create
                @score = Score.new(params[:score])    

                if @score.save
                  # Handle a successful save.
                else
                  render 'new'
                end
              end 

              private

                def user_params
                  params.require(:score).permit(:golferid1, :golferid2, :golferid3,
                                               :golferid4, :golferid5, :golferid6)
                end

              end

I need to record the golderid which will be taken from the golfers table add to the records in the score table. This is the tricky part for me. I also need to store the Users id which could be taken from their login and record that in the scores record as well.

Golfers table

            golfers (
            golferid INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
            firstname VARCHAR(30) NOT NULL,
            secondtname VARCHAR(30) NOT NULL,
            country VARCHAR(50),
            worldranking int(3),
            tournamentposition int(2),
            group1 boolean,
            group2 boolean,
            group3 boolean,
            group4 boolean,
            group5 boolean,
            group6 boolean,
            day1score int(2),
            day2score int(2),
            day3score int(2),
            day4score int(2),
            totalscore int(3),
            golfscoretotal int(3)
            );

Scores table

            scoreid int(6) UN AI PK 
            userid int(11) 
            golfergroupid1 int(6) 
            golfscoretotal1 int(3) 
            golfergroupid2 int(6) 
            golfscoretotal2 int(3) 
            golfergroupid3 int(6) 
            golfscoretotal3 int(3) 
            golfergroupid4 int(6) 
            golfscoretotal4 int(3) 
            golfergroupid5 int(6) 
            golfscoretotal5 int(3) 
            golfergroupid6 int(6) 
            golfscoretotal6 int(3) 
            totalscore int(4)

Golfers Model in RoR

            class Golfer < ActiveRecord::Base
            belongs_to :score 

            end

Scores Model in RoR

            class Score < ActiveRecord::Base
            belongs_to :user

            end

Any help would be greatly appreciated. Im stuck on this issue now for a few days.

You can do something like this:

<% {1 => 1, 2 => 11}.each_pair do |pull_no, start_no| %>
  <h2> <%= "Pool #{pull_no}"  %></h2>
  <ul class="users">
    <%= field_set_tag do %>
      <%= f.hidden_field :("golferidgroup#{pull_no}"), nil %>
      <% 10.times do |i| %>
        <%= render Golfer.where(:golferid => start_no + i) %>
        <%= f.radio_button :("golferidgroup#{pull_no}"), start_no + i, :checked => false %>
      <% end %>
    <% end %>
  </ul>
<% end %>
