Parse Feeds/Blogs From External Sites To Your Rails App

Step 1

Add gem in your gem file

gem 'feedzirra'

Run the bundle install

Step 2

Go to your required controller and add the following at top.

require 'feedzirra'

Step 3

In your controller create a method and add the following block to fetch feeds from external sites


feed = Feedzirra::Feed.fetch_and_parse("http://feeds.feedburner.com/TechCrunch/gaming")
@entry = feed.entries

It will fetch the list of feeds from the blog site.

Step 4

Add the following block in your view page


<%@entry.each do |feed|%>
 <%= link_to "#{feed.title.sanitize}", "#{feed.url}",:target => "_blank" %>
 <%=feed.author%>  
 <%=feed.published%>
 <%=feed.categories %>
<%end%>

Get user accessing ip address in rails?

Get user accessing ip address rails?

request.ip ->returns the ip, whether is is a local proxy ip (localhost address) or not.
*request.remote_ip -> is smarter and gets the ip address of the client outside of local proxies.
3)If you are using apache in front of a mongrel, then remote_ip will return the source address of the request, which in this case will be local host because the Apache web server is making the request, so instead put this in your controller:

@remote_ip = request.env["HTTP_X_FORWARDED_FOR"]
