Mongo::Error::NoServerAvailable

I just configured Mongoid for a Rails project, ran rails g mongoid:config edited my mongoid.yml to be like below.

development:
  clients:
    default:
      database: abacus_development
      # Provides the hosts the default client can connect to. Must be an array
      # of host:port pairs. (required)
      hosts: 
        - localhost
      options:

test:
  clients:
    default:
      database: abacus_test
      hosts:
        - localhost
      options:
        read:
          mode: primary
        max_pool_size: 1

Then went on thinking everything to be running fine, to scaffold a controller and model called Activity. With that I ran rails s. The app runs fine at localhost:3000, but the moment I get to localhost:3000/activites it spits out this.

ActionView::Template::Error (No server is available matching preference: #<Mongo::ServerSelector::Primary:0x007fbda47c4110 @tag_sets=[], @options={:database=>:abacus_development}, @server_selection_timeout=30>):
        15:   </thead>
        16:
        17:   <tbody>
        18:     <% @activities.each do |activity| %>
        19:       <tr>
        20:         <td><%= activity.amount %></td>
        21:         <td><%= activity.indicator %></td>   app/views/activities/index.html.erb:18:in `_app_views_activities_index_html_erb___73038992978597028_70226242222820'

Any ideas?

Try with 

sudo mongod

I think it should work

Mongo runs on port 27017 by default, try to change your hosts configuration to localhost:27017 in your mongoid.yml.

You are running mongo right? Probably with 'mongod' if you're on a mac or 'sudo service mongod start'. Might be a stupid answer but you never know
