I must have something wrong either with my erb or my route, because I'm getting this crazy suffix on my URI when I press my Merge button. From what I can tell, this suffix is an array with the date the article was created and it's permalink, and I have no idea how it got it there instead of the id.

new.html.erb

# in /admin/content
# code excluded

<h3><%= _("Merge Articles")%></h3>
<%= form_tag merge_articles_path(@article) do %>
      <%= text_field_tag :sender_id, nil, :placeholder => 'Article ID'  %>
      <%= submit_tag 'Merge' %>
<% end %>

routes.rb

# code excluded

# Admin/XController
%w{advanced cache categories comments content profiles feedback general pages
   resources sidebar textfilters themes trackbacks users settings tags redirects seo post_types }.each do |i|
  match "/admin/#{i}", :to => "admin/#{i}#index", :format => false
  match "/admin/#{i}(/:action(/:id))", :to => "admin/#{i}", :action => nil, :id => nil, :format => false
end

# My route
match '/admin/content/merge_articles/:id', to: 'admin/content#merge_articles', as: 'merge_articles'

URI error

/admin/content/merge_articles/[2013, "08", "18", "merge-into-me"]
