Rails 4.2: Client Side Validations for Associations - ruby-on-rails

Question

I have a complex form with associations that I would like to view validation errors inline in real-time. I stumbled upon RailsCasts episode Client Side Validations and decided to take that approach and installed the gem.
gem 'client_side_validations',
github: "DavyJonesLocker/client_side_validations",
branch: "4-2-stable"
As required by the gem, I placed validate: true at the top of the form helper and saw that it only worked on attribute fields and not on the associated objects.
For example, when the field name is blank, it displays the error inline stating can't be blank. When the user has not selected a program, I would like it to inform the user Need a program! but it does not. Currently, it simply throws the flash[:error] message I stated in the controller that "There was a problem launching your Campaign." with no inline message specific to the program select box.
Here is the set-up..
views/campaigns/_forms.html.erb
<%= form_for #campaign, url: {action: "create"}, validate: true do |f| %>
<%= f.label :campaign_name, "Campaign Name", class: "right-label" %>
<%= f.text_field :name %>
<%= f.label :comments %>
<%= f.text_area :comment %>
<%= f.label :program %>
<%= f.select :program_id,
Program.all.collect { |p| [ p.name, p.id ] }, { include_blank: true }, validate: { presence: true } %>
<%= f.label :data_file, "Data File (.zip)", class: "right-label" %>
<%= select_tag :uploadzip_id,
options_from_collection_for_select(
Uploadzip.all, :id, :file_name
), { include_blank: "Include a Zip File" } %>
<%= f.label :additional_files %>
<ul><%= f.collection_check_boxes :uploadpdf_ids, Uploadpdf.last(5).reverse, :id,
:file_name, { mulitple: true } do |b| %>
<li><%= b.label do %>
<%= b.check_box + truncate(File.basename(b.text,'.*'), length: 45) %>
<% end %>
</ul><% end %>
<%= render 'target', :f => f %>
<%= f.submit "Confirm & Execute", id: "campaign-create-button" %>
<% end %>
views/campaigns/_target.html.erb
<%= f.label :plan, "Pick a Plan", class: "right-label" %>
<%= f.select :plan_id,
Plan.all.collect { |p|
[ p.name, p.id ]
}, { include_blank: true } %>
<%= f.label :channels, "Distribution Channel", class: "right-label" %>
<ul class="channels-list">
<% ["Folder", "Fax", "Email"].each do |channel| %>
<li><%= check_box_tag "campaign[channels][]", channel,
#campaign.channels.include?(channel),
id: "campaign_channels_#{channel}" %> <%= channel %></li>
<% end %>
</ul>
app/models/campaign.rb
class Campaign < ActiveRecord::Base
belongs_to :program
belongs_to :plan
has_many :uploadables, dependent: :destroy
has_many :uploadpdfs, through: :uploadables
has_one :uploadzip, dependent: :nullify
validates :name, presence: true,
uniqueness: true
validates :program, presence: { message: "Need a program!"}
validates :uploadzip, presence: true
validates :uploadpdf_ids, presence: true
serialize :channels, Array
end
app/controllers/campaigns_controller.rb
class CampaignsController < ApplicationController
def index
#campaigns = Campaign.all.order("created_at DESC")
end
def new
#campaign = Campaign.new
end
def create
#campaign = Campaign.new(campaign_params)
if #campaign.save
zip = Uploadzip.find(params[:uploadzip_id])
zip.campaign = #campaign
zip.save
flash[:success] = "Campaign Successfully Launched!"
redirect_to #campaign
else
flash[:error] = "There was a problem launching your Campaign."
redirect_to new_campaign_path
end
end
def show
#campaign = Campaign.includes(:program, :uploadzip, :plan, :uploadpdfs).find(params[:id])
end
private
def campaign_params
params.require(:campaign).permit(:name, :comment, :plan_id, :program_id, :campaign_id, uploadpdf_ids: [], channels: [])
end
end
I also followed this tutorial that provided code to help display validation errors for associations in the view.
config/initializers/errors_for_associations.rb
module ActionView::Helpers::ActiveModelInstanceTag
def error_message_with_associations
if #method_name.end_with?('_ids')
# Check for a has_(and_belongs_to_)many association (these always use the _ids postfix field).
association = object.class.reflect_on_association(#method_name.chomp('_ids').pluralize.to_sym)
else
# Check for a belongs_to association with method_name matching the foreign key column
association = object.class.reflect_on_all_associations.find do |a|
a.macro == :belongs_to && a.foreign_key == #method_name
end
end
if association.present?
object.errors[association.name] + error_message_without_associations
else
error_message_without_associations
end
end
alias_method_chain :error_message, :associations
end
