Carrierwave images are not displaying, works everywhere else on the site - html

Question

I'm using Carrierwave with Rails to upload and display images. I've been using it for articles and other parts of my site without a problem but for some reason it's not working for the model I just created. I can see the space for the image tag rendered without the image and then disappear quickly when the page loads. Nothing like this has occurred until I tried it with this model which isn't much different from my other models:
class Ad < ActiveRecord::Base
validates_numericality_of :zip_code
validates_presence_of :image, :advertiser
mount_uploader :image, ImageUploader
end
My create and index actions:
def create
#ad = Ad.new(params[:ad].permit(:image, :advertiser, :zip_code))
if #ad.save
redirect_to :back
else
flash[:error] = "Invalid input"
redirect_to :back
end
end
def index
#new_ad = Ad.new
#ads = Ad.all.reverse
end
My _new partial:
<div id="card">
<%= form_for #new_ad, html: {multipart: true, "data-ajax" => false} do |f| %>
<p>
<%= f.file_field :image %>
</p>
<p>
<%= f.text_field :advertiser, placeholder: "Advertiser" %>
</p>
<p>
<%= f.text_field :zip_code, placeholder: "Zip code" %>
</p>
<p>
<%= f.submit "Upload" %>
</p>
<% end %>
</div></br>
My index view:
<%= render "new" %>
<% for ad in #ads %>
<div id="card">
<div align="center">
<%= image_tag ad.image %>
<%= ad.advertiser %>
<%= ad.zip_code %>
</div>
</div></br>
<% end %>

As per my understanding problem is with your index view.
<%= image_tag ad.image %>
you are using ad.image this will return you imageuploader object not image path. So instead of using ad.image you can use ad.image.url(relative path) or ad.image.current_path(absolute path)
<%= image_tag ad.image.url %>
