Override behavior from ActionDispatch::Routing::UrlFor

When Jets include ActionDispatch::Routing::UrlFor is in the Jets::Controller::Base class It sets @_routes = nil

We need to set @_routes to the Jets::Controller::Request routes object to provide a Jets custom routes object that’s compatiable the Rails routes object.

Why does @_routes have to be set?

How this works is a bit hard to follow. Here’s the current trace with actionpack 7.0.8

Here’s where controller render goes from controller-land to view-land.

action_controller/metal/rendering.rb:158:in `render_to_body'
action_view/rendering.rb:114:in `render_to_body'

In action_view/rendering.rb render_to_body => _render_template is called and a view_context is created.

def view_context
  view_context_class.new(lookup_context, view_assigns, self)
end

self is the <PostsController>. The controller instance is the _routes is used. The view_context_class is somehow a wrapped anonymous class that has the ActionView::Base#initialize method.

Usage:

module Jets::Controller
  class Base < Jets::Lambda::Functions
    ...
    include Compat::RouteSet::ControllerPrepend
    ...
    include ActionController::UrlFor # includes ActionDispatch::Routing::UrlFor
    ...
    include Compat::RouteSet::ControllerAppend
