```ruby
Spree::Tracker.class_eval do
  belongs_to :store

  def self.current(store_key)
    Spree::Tracker.where(active: true, environment: Rails.env).joins(:store).where("spree_stores.code = ? OR spree_stores.url LIKE ?", store_key, "%#{store_key}%").first
  end
end
```

Fix for removal of Tracker.environment
user
```ruby
Spree::Tracker.class_eval do
  belongs_to :store

  def self.current(store_key)
    Spree::Tracker.where(active: true).joins(:store).where("spree_stores.code = ? OR spree_stores.url LIKE ?", store_key, "%#{store_key}%").first
  end
end
```
