Rails 4 Permitted Params with nested attributes - ruby-on-rails

Question

Alright, been looking everywhere for this one. Tried all the solutions. Maybe someone can help on this.
So, I have a WebRequest model that has many WebSites. Each WebSite belongs to a WebRequest. My problem is in the nested form. Ive gone in an permitted the params (atleast, based on the documentation I have) and everything works fine until I go into the server logs. Posted below
class WebRequest < ActiveRecord::Base
has_many :web_sites
accepts_nested_attributes_for :web_sites
end
and here is the WebSite model
class WebSite < ActiveRecord::Base
belongs_to :web_request, dependent: :destroy
end
_form.html.erb
<% 1.times do %>
<%= f.fields_for :web_site do |ff| %>
<%= ff.input :url %>
<%= ff.input :description %>
<% end %>
<% end %>
WebRequests Controller
class WebRequestsController < ApplicationController
def new
#web_request = WebRequest.new
# #web_request.web_sites.build
end
def index
#web_requests = WebRequest.all
end
def create
#web_request = WebRequest.new(web_request_params)
respond_to do |format|
if #web_request.save
RequestMailer.web_request_submit(#web_request).deliver
format.html { render partial: 'success' }
format.json { render action: 'show', status: :created, location: #web_request }
else
format.html { render action: 'new' }
format.json { render json: #web_request.errors, status: :unprocessable_entity }
end
end
end
def web_request_params
params.require(:web_request).permit(:web_needs, :primary_goal, :secondary_goal, : :call_to_action, :hero_image, :image_count, :existing, :resources, :web_examples, :special_functions, :social_network, web_sites_attributes: [:id, :url, :description])
end
end
And here is the server log:
Started POST "/web_requests" for 127.0.0.1 at 2014-07-10 15:56:12 -0400
Processing by WebRequestsController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"0iisNgGk/AhC4jRrp1cmKWVCBsCcSx5G2dueEI/+p2A=", "web_request"=>{"web_needs"=>"", "primary_goal"=>"", "secondary_goal"=>"", "call_to_action"=>"", "hero_image"=>"", "image_count"=>"", "existing"=>"", "web_site"=>{"url"=>"TROLL", "description"=>"TROLL"}, "resources"=>"", "special_functions"=>"", "social_network"=>""}, "commit"=>"Create Web request"}
Unpermitted parameters: web_site
Notice at how the form fields get passed but they get restricted out of making it to the DB.
THANKS!
Update::
Here is the full form path:
<%= simple_form_for(#web_request) do |f| %>
<% if #web_request.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#web_request.errors.count, "error") %>
prohibited this Web Request from being saved:</h2>
<ul>
<% #web_request.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="container">
<div class="field">
<%= f.input :web_needs, label: 'What web needs do you have?' %>
</div>
<div class="container"><h5>Please list below 5 URL's and explanations of why you like them.</h5></div>
<% 1.times do %>
<%= f.fields_for :web_sites do |ff| %>
<div class="field">

</div>
<div class="field">

<% end %>
<div class="field">

Answer 1

Add to controller in new action:
def new
#web_request = WebRequest.new
#web_site = #web_request.web_sites.build
end
and form:
<%= f.simple_fields_for #web_site do |ff| %>
<%= ff.input :url %>
<%= ff.input :description %>
<% end %>
<% end %>
and web_request_params:
def web_request_params
params.require(:web_request).permit(:web_needs,
:primary_goal,
:secondary_goal,
:call_to_action,
:hero_image,
:image_count,
:existing,
:resources,
:web_examples,
:special_functions,
:social_network,
{ web_sites: [:id, :url, :description] })
end

Answer 2

In your controller in web_request_params change web_sites_attributes for web_site_attributes
In your controller remove the comment from #web_request.web_sites.build
In your view remove 1.times do
In yor form change f.fields_for :web_sites do |ff| with f.simple_fields_for :web_sites do |ff|
