Question

Firstly im new to Ruby and this could possibly be the wrong approach, however…

I’m trying to set two values in my select, using simple form. So far i have:

<%= f.input :rsvp, :collection => [:attending, :not_attending], :prompt => 'Choose one...' %>

This works fine, i can load the page, choose a selection. Now RSVP is a field in my db:

reply DB

class CreateReplies < ActiveRecord::Migration
  def change
    create_table :replies do |t|
      t.string :name
      t.text :menu
      t.integer :rsvp

      t.timestamps
    end
  end
end

reply.rb

class Reply < ActiveRecord::Base
  attr_accessible :menu, :name, :rsvp, :user_id
  belongs_to :user
end

My thinking was changing rsvp from :string where i have to type attending / not attending to an :integer so that i could yes likea true / false value on the two choices. Now like i said i’m very new to this, but in my head, this might be how to go about such a thing.

Because im going to try and get a count of how many are attending / not attending and display on the index. Sorry if anything is missing, let me know and ill update the question.

I think you went on the right way. You can make a group radio button for user select, try:

<%= f.input :rsvp, :collection => [['Attending',1], ['Not Attending',0]], as: :radio_buttons, label_method: first, value_method: last, :prompt => 'Choose one...' %>

Or this way:

<%= f.collection_radio_buttons :rsvp, [[true, 'Attending'] ,[false, 'Not Attending']], :first, :last %>
