Defined in:
lib/scribo/liquid/tags/fields_for_tag.rb

Overview

Exposes additional model objects, similar to form, but it doesn’t create a form-tag.

Basic usage:

{%fields_for location%}
  {%text_field city%}
{%endform%}

It will automatically build the association if need be. For polymorphic it needs a hint:

{%fields_for scribable Domain%}
  {%text_field city%}
{%endform%}

Available variables:

form.model

model specified

form.class_name

class name of the model specified (original name, not the drop)

form.errors

errors of the exposed object

require_relative ‘../drops/form_drop’
