Question

I am using Simple_form with Decent_exposure, Strong_parameters I have the following setup and I can post to households but nothing gets posted to neighbors

model

class Household < ActiveRecord::Base
 include ActiveModel::ForbiddenAttributesProtection

has_many :neighbors
 accepts_nested_attributes_for :neighbors

view

= simple_nested_form_for household do |f|
  = f.input :household_name
  = f.simple_fields_for :neighbor, Neighbor.new do |neighbor_form|
  = neighbor_form.input :first_name
  = neighbor_form.input :middle_name
  = neighbor_form.input :last_name
  = neighbor_form.input :address

  = f.button :submit

Based on the following from my log it looks like the form is working but it is not saving to neighbors the nested model – I have tried both simple_fields_for :neighbor do and simple_fields_for :neighbor, Neighbor.new do hoping that creating a new neighbor would help but it doesn’t.

Make sure that you include neighbors_attributes in the allowable parameters.
