Mass assignment warning when using nested attributes with Devise
I'm having trouble with nested attributes and Devise. A similar issue to How do I use nested attributes with the devise model. As far as I can tell I've got everything set up as recommended here: Override devise registrations controller
I've set up the associations for Users and Subscriptions, I have "accepts_nested_attributes_for"
, and included the :subscriptions_attributes
in attr_accessible
, but I get a warning from the Devise controller.
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,:recoverable, :rememberable, :trackable, :validatable
validates_presence_of :first_name, :last_name
has_many :subscriptions
accepts_nested_attributes_for :subscriptions
attr_accessible :first_name, :last_name, :email, :password, :password_confirmation, :remember_me, :subscriptions_attributes
...

class Subscription < ActiveRecord::Base
belongs_to :user
validates_presence_of :user_id, :chargify_subscription_id, :chargify_product_handle
attr_accessible :user_id, :chargify_subscription_id, :chargify_product_handle
...
end
devise/registrations/new.html.erb :
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<p><%= f.label :first_name %><br />
<%= f.text_field :first_name %></p>
...
<%= f.fields_for :subscription do |s| %>
<p><%= s.label :chargify_subscription_id %><br />
<%= s.text_field :chargify_subscription_id %></p>
...
I'm getting the following warning:
Started POST "/users" for 127.0.0.1 at Sat May 14 12:38:49 -0700 2011

WARNING: Can't mass-assign protected attributes: subscription
I've tried using subscription_attributes
(singular) in attr_accessible
but that doesn't work.
Any suggestions for what I might be doing wrong? Thanks.
Since you have a has_many association between your User and Subscription model, I believe you need to specify fields_for :subscriptions
rather than fields_for :subscription
.
<%= f.fields_for :subscriptions do |s| %>
<p><%= s.label :chargify_subscription_id %><br />
<%= s.text_field :chargify_subscription_id %></p>
...
The attributes within the fields_for scope will then be passed using the subscriptions_attributes parameter, which should work since you have attr_accessible :subscriptions_attributes
.
For more examples of nested has_many association forms, check out the 'Nested Attributes Examples' section (one-to-many) of the Rails documentation.
