Railscasts 168 - Feedjira Not Working

I'm trying to make a RoR app that parses an RSS feed then digs through it for keywords. To add RSS I'm following this: http://railscasts.com/episodes/168-feed-parsing

And it's not working. I've installed the gem and rebooted the rails server. The config/environment line prevents rake db:migrate from working, giving this error:

/config/environment.rb:7:in `<top (required)>': undefined local variable or method `config' for main:Object (NameError)

so I left it out.

The FeedEntry console line, in which I pass the url, gives this error: FeedEntry.update_from_feed("feed://seekingalpha.com/market_currents.xml") NameError: uninitialized constant FeedEntry::Feedzirra

And the view code gives this error: wrong number of arguments (1 for 0) with this in the extracted source:

<div class="container-fluid" id="seeking_alpha">
<h3>Seeking Alpha Feed</h3>
<ul class="list-group">
<% for entry in FeedEntry.all(:limit => 10, :order => "published_at desc") %>
  <li class="list-group-item"><%= link_to h(entry.title), entry.url %></li>
<% end %>
</ul>

Can you help me fix the problems here? Other than being a complete Rails n00b, I'm guessing my problem is that Feedjira isn't initialized, possibly caused by leaving that line out due to using a newer version of Rails (4.0) and Ruby (2.1.1) than the tutorial does. And perhaps the .xml file format on the feed is also causing a problem. It seems like Feedjira just doesn't want to exist outside of its own model. Any ideas would be very appreciated.

All of your errors stem from omitting that first configuration statement.

If you look at the source code from the Railscast, Ryan defines config like this in environment.rb:

Rails::Initializer.run do |config|

Though we can't see your environment.rb, your error states you have not defined config.

Without config, you can't run migrations, so no FeedEntry model, hence the errors in your console script and your view. You will also need that statement to use Feedzirra::Feed in your model-- it has to work.

To recap:

  • Define config in config/environment.rb
  • Run your migration
  • Compare with the Railscast source code if you get stuck

Also, this Railscast is old (2009); 'Feedzirra' has been renamed 'Feedjira' and you can add it to your Gemfile:

gem 'feedjira'

You'll have to look at the docs (http://feedjira.com) for any changed functionality in the gem, but that's probably going to be an easier path.

Good luck!
