Facebook like button displayed for particular blog post. When a user clicks on this button I would like that particular information about the post he is viewing (blog teaser image, blog teaser description, blog post URL) is displayed in his news feeds:
<asside id="share_pa">
<ul>
<li class="facebook">
<div class="fb-like" data-href="http://my-site.com<%= refinery.blog_post_path %>"
data-send="false" data-layout="box_count" data-width="55" data-show-faces="false"></div>
</li>
</ul>
</asside>
Facebook like button in the footer of my site. When liked it needs to show general information about my site (general description, site logo and site URL)
<div class="fb_like_btn">
<h2>Lajkajte nas na Facebooku</h2>
<div class="fb-like" data-href="http://my-site.com"
data-send="false" data-width="340" data-show-faces="false"></div>
</div>
this is the script I included right after the <body> section (generated by facebook):
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=MY_APP_ID";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
I have overridden post.rb model and added face_book_img method that should find the source path (src) of the image teaser of particular blog post:
