Github activity feed urls dont include domain

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_feed2.2.4 :006 > github_feed.entries.first.content=> "<!-- pull_request -->\n<svg aria-label=\"Pull request\" class=\"octicon octicon-git-pull-request dashboard-event-icon\" height=\"32\" role=\"img\" version=\"1.1\" viewBox=\"0 0 12 16\" width=\"24\"><path d=\"M11 11.28V5c-.03-.78-.34-1.47-.94-2.06C9.46 2.35 8.78 2.03 8 2H7V0L4 3l3 3V4h1c.27.02.48.11.69.31.21.2.3.42.31.69v6.28A1.993 1.993 0 0 0 10 15a1.993 1.993 0 0 0 1-3.72zm-1 2.92c-.66 0-1.2-.55-1.2-1.2 0-.65.55-1.2 1.2-1.2.65 0 1.2.55 1.2 1.2 0 .65-.55 1.2-1.2 1.2zM4 3c0-1.11-.89-2-2-2a1.993 1.993 0 0 0-1 3.72v6.56A1.993 1.993 0 0 0 2 15a1.993 1.993 0 0 0 1-3.72V4.72c.59-.34 1-.98 1-1.72zm-.8 10c0 .66-.55 1.2-1.2 1.2-.65 0-1.2-.55-1.2-1.2 0-.65.55-1.2 1.2-1.2.65 0 1.2.55 1.2 1.2zM2 4.2C1.34 4.2.8 3.65.8 3c0-.65.55-1.2 1.2-1.2.65 0 1.2.55 1.2 1.2 0 .65-.55 1.2-1.2 1.2z\"></path></svg>\n\n<div class=\"time\">\n  <relative-time datetime=\"2016-09-23T07:30:24Z\">Sep 23, 2016</relative-time>\n</div>\n\n<div class=\"title\">\n  <a href=\"/prasadsurase\" data-ga-click=\"News feed, event click, Event click type:PullRequestEvent target:actor\">prasadsurase</a> opened pull request <a href=\"/joshsoftware/code-curiosity/pull/136\" data-ga-click=\"News feed, event click, Event click type:PullRequestEvent target:pull\">joshsoftware/code-curiosity#136</a>\n</div>\n\n<div class=\"details\">\n  <a href=\"/prasadsurase\"><img alt=\"@prasadsurase\" class=\"gravatar\" height=\"30\" src=\"https://avatars3.githubusercontent.com/u/562052?v=3&amp;s=60\" width=\"30\" /></a>\n  <div class=\"message\">\n    <blockquote>Fixed controller method scopes.

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?
