Github activity feed urls dont include domain - ruby-on-rails-4

Question

I want to display a user's activity feed in an rails application. I am using feedjira.
2.2.4 :006 > xml_feed = Feedjira::Feed.fetch_raw "https://github.com/prasadsurase.atom"
2.2.4 :006 > github_feed = Feedjira::Feed.parse xml_feed
2.2.4 :006 > github_feed.entries.first.content

when rendering the content for every entry from github_feed.entries in haml as raw, the links do not contain the domain https://github.com/ but contain only the path. This causes problem as such that the rendered links on the UI contain the app domain and not github. How do we fix this?

Answer 1

Since github atom feeds provides the content with relative url's you might want to replace them with absolute references.
This could be done with
gsub( %r{<a href=\"/},'<a href="https://github.com/')
And thus replace your:
2.2.4 :006 > github_feed.entries.first.content
with
2.2.4 :006 > github_feed.entries.first.content.gsub( %r{<a href=\"/},'<a href="https://github.com/')
