How to render views correctly on rake?

Question

view = ActionView::Base.new(ActionController::Base.view_paths, {}, ActionController::Base.new)

# works fine
puts view.render(file: 'books/index')

# doesn't work
puts view.render('books/index', layout: 'application')

And it doesn't work when there is user_signed_in? in view (view.render(file: 'books/index')).

Answer 1

You have not added a partial, _index.html.erb in your app/views/books

Answer 2

I think you need to create _index.html.erb (partial file) in app/view/books folder.
