Undefined local variable or method `view_renderer'

[Math3v]

Trestle version: 0.8.7 Rails version: 5.2.0

How to reproduce:

...
form do |user|
  render 'user_select'
end
...

Error: Undefined local variable or method `view_renderer' for #<Trestle::Form::Builder:0x00007fc2f6b58388>

How to fix:

• [ ] Monkey patch Trestle::Form::Renderer to include ActionView::Helpers::RenderingHelper
• [ ] Split form into well blocks in order to render partial

module Trestle
  class Form
    class Renderer
      include ::ActionView::Helpers::RenderingHelper
    end
  end
end
...
form do |user|
  well do
    render 'user_select'
  end
end
...

Are you able to post the full stack trace? I'm not seeing the results that you are with the same versions of Trestle and Rails.
