Carrierwave Gem Not Working - ruby-on-rails

Question

I really have no idea what to do now. Image is showing up as nil in database. There are no errors showing up.
Model
class Resource < ActiveRecord::Base
mount_uploader :image, ImageUploader
attr_accessible :title, :url, :description, :tag
validates :title, presence: true, uniqueness: true
validates :url, presence: true
validates :description, presence: true
validates :tag, presence: true
belongs_to :user
acts_as_votable
validates_processing_of :image
validate :image_size_validation
private
def image_size_validation
errors[:image] << "should be less than 500KB" if image.size > 0.5.megabytes
end
end
Image Uploader
class ImageUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
version :thumb do
process :resize_to_fill => [100, 100]
end
def extension_white_list
%w(jpg jpeg gif png)
end
end
Form Partial
<%= form_for #resource, html: { multipart: true } do |f| %>
<% if #resource.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#resource.errors.count, "error") %> prohibited this pet
from being saved:</h2>
<ul>
<% #resouce.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :url %><br>
<%= f.text_area :url%>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_area :description %>
</div>
<div class="field">
<%= f.label :tag %><br>
<%= f.text_area :tag %>
<div class="field">
<%= f.label :image %><br>
<%= f.file_field :image %>
<% if f.object.image? %>
<%= image_tag f.object.image.thumb.url %>
<%= f.label :remove_image %>
<%= f.check_box :remove_image %>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
Image tag in show
<%= image_tag #resource.image.thumb.url %>
Controller
class ResourcesController < ApplicationController
before_action :authenticate_user!, except: [:index, :show]
def index
#resources = Resource.page(params[:page]).per(15)
end
def show
#resource = Resource.where(:id => params[:id]).first
end
def edit
#resource = Resource.where(:id => params[:id]).first
end
def new
#resource = current_user.resources.build
end
def update
#resource = Resource.where(:id => params[:id]).first
respond_to do |format|
if #resource.update_attributes(resources_params)
format.html { redirect_to #resource, :notice => 'Resource was successfully
updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #resource.errors, :status =>
:unprocessable_entity }
end
end
end
def destroy
#toDelete = Resource.where(:id => params[:id]).first
puts #toDelete.id
if #toDelete.destroy
flash[:notice] = "Successfully deleted post!"
redirect_to root_path
else
flash[:alert] = "Error updating post!"
end
end
def create
#resource= current_user.resources.build(resources_params)
if #resource.save
redirect_to root_path
flash[:alert] = "Successfully created new resource!"
else
render "new"
end
end
def upvote
#resource = Resource.find(params[:id])
#resource.upvote_by current_user
redirect_to :back
end
def downvote
#resource = Resource.find(params[:id])
#resource.downvote_from current_user
redirect_to :back
end
private
def resources_params
params.require(:resource).permit(:title, :url, :description, :image, :tag)
end
end
If there is any other file you would like to see, I will post it.
Thank You.
EDIT
It was just a versioning problem......
