Url_for in email sent by rake team in rails 4

I have a rake challenge that sends out daily emails about player activity throughout the day. (See sample code below.) If I run PlayerActivityMailer.activity_report.deliver

in my console everything works fine. However, when I try to call the rake task, I get the following error:

rake aborted!
ActionView::Template::Error: arguments passed to url_for can't be handled.
Please require routes or provide your own implementation

      

        
        
        
      

    

After some research, I found that in Rails 4 they are completely nerfed ActionView::Helpers::UrlHelper.url_for

( http://apidock.com/rails/v4.1.8/ActionView/Helpers/UrlHelper/url_for - note the giant red minus sign under 4.0.2). If you look at the source, you see the error I see - it no longer accepts parameters. As far as I can tell, this functionality still exists in other url_for

s, such as ActionDispatch::Routing::UrlFor

. Additionally, the error message suggests enabling Rails.application.routes.url_helpers

.

What i tried

• include ActionDispatch::Routing::UrlFor
  
  both in the task rake (inside the task) and in the mailbox (both simultaneously and each separately)
• include Rails.application.routes.url_helpers
  
  in the same locations and configurations including and UrlFor
  
  .

The error still persists. My guess is that the pageview still insists on using the version ActionView::Helpers::UrlHelper

url_for

. I don't think I can actually include things in the views (which are sloppy looking and hacky, even if I could).

Sample code (heavily sanitized)

config / environtments / development.rb:

config.action_mailer.default_url_options = { host: 'localhost:3000' }

      

        
        
        
      

    

Lib / tasks / player.rake:

namespace :player do
  task :activity => :environment do
    PlayerActivityMailer.activity_report.deliver
  end
end

      

        
        
        
      

    

App / senders / player_activity_mailer.rb:

class PlayerActivityMailer < ActionMailer::Base
  def activity_report
    @activities = PlayerActivity.all
    mail(to: 'foo@bar.com', subject: 'activity report')
  end
end

      

        
        
        
      

    

app / views / player_activity_mailer / activity_report.html.erb:

<% @activites.each do |activity| %>
    Player: <%= link_to activity.player.name, player_url(id: activity.player.id) %>
    ...
<% end %>

      

        
        
        
      

    

I also have a Player model, resources :players

in my routes.rb file and a PlayerActivity class with a Player association.

I am currently using a (really terrifying) workaround @base_url = Rails.configuration.action_mailer.default_url_options[:host]

in my post action and "http://#{@base_url}/players/#{activity.player.id}"

in my view instead of the player_url part.

Help!
