Overview

Form adds a form tag, when you specify a model it will use and expose that to nested fields. Exposing a model will ease the creation of nested fields.

Basic usage:

{%form%}
  {%text_field name:"name" value:"Pencil"%}
{%endform%}

Advanced usage:

{%form product%}
  {%text_field name%}
{%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’
