How do i access main_app?

[nir0]

i've generated an engine, it uses standard layout with cells inside. menu cell renders namespaced (wrong) links, so i found i need to use main_app.profile_path
sadly, cells don't know what is this, i've been trying to include Rails::Engine with no luck. what should i include to make main_app work?

This issue must be raised in cells-rails, because cells has nothing to do with Rails.
