formtastic with spree check_boxes using collection not saving checked items in edit form

Question

I am using formtastic-2.2.1, Spree 1.3 and Rails 3.2.18.

This in my form input that I am having issues with:

  = f.input :collection_products, :as => :check_boxes, :label => false, :collection => Spree::Product.order("name").all

The issue I am having is when I create a new collection_page and hit edit previously selected items are unselected in the edit form, all the other inputs are working as expected.

I've tried it with a simple collection, like :collection => ["x", "y", "z"]

ie:. If I select "x", "y" and try to edit it, they are no longer selected.

Collection Page model:

class CollectionPage < ActiveRecord::Base
    has_many :spree_products, :class_name => Spree::Product

and added belongs_to :spree_collection_pagesto product_decorator.rb

I'm having the exact same issue as formtastic check_boxes using collection not saving checked items in edit form

Would be awesome if someone can help out!

Thanks a lot.

Answer 1

I ended up solving it by using simple_form instead and did the following on my form:

= f.association :spree_products, :collection => Spree::Product.order("name").all, :prompt => "Choose products for this collection"
