How to render a view as a entity field on form edit? I'm looking for a module (or alternative solution) to render view in the field.

Similar to Viewfield, but it should be rendered when filling the form (Entityform or node edit).

The purpose for that is to include Commerce views in the entity form (such as commerce_cart_form, commerce_cart_summary, commerce_payment_order) which are actually views.
Use EVA  module. It will provide the view as field. So in display settings you can assign views the region you would like. Quite simple and useful module
