can't convert symbol into integer error when saving user - ruby-on-rails

Question

So here is my issue. I have been working with users I created at the beginning of my project for a month now. Today I switched from sqllite to sqlserver to meet client requirements and when I went to use my registration form to create a new user I got the following error:
can't convert Symbol into Integer
Parameters:
{"utf8"=>"✓",
"authenticity_token"=>"51nF50CYGNqz3N4o7TUYSyWeTadulXojQBPqERjvlcY=",
"user"=>{
"email"=>"test#blizzardlabs.com",
"login"=>"bgarrison",
"password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]",
"profile_attributes"=>{
"prefix"=>"",
"first_name"=>"Bill",
"last_name"=>"Garrison",
"suffix"=>"",
"birthday"=>"1983-06-01",
"phone_numbers_attributes"=>{
"0"=>{
"info"=>"1234567890",
"label"=>"Cell"
}
}
}
},
"commit"=>"Register"}
I have a feeling that at some point I messed up the registration process but I can't for the life of me figure out where. User-> has_one profile-> has_many phone_numbers.
User Controller:
def create
#user = User.new(params[:user])
if #user.save
#profile = #user.profile
flash[:notice] = "Your account has been created."
redirect_to(#user)
else
flash[:notice] = "There was a problem creating you."
render :action => :new, :layout => 'logged_out'
end
end
User Model:
class User < ActiveRecord::Base
# Accessible attributes
attr_accessible :login,
:email,
:password,
:password_confirmation,
:profile_attributes,
:active
# Associations
has_one :profile, dependent: :destroy, autosave: true
# Allows for a profile hash in user creation (stored in :profile_attributes)
accepts_nested_attributes_for :profile
Profile Model:
class Profile < ActiveRecord::Base
# Accessible Attributes
attr_accessible :birthday,
:company_id,
:first_name,
:last_name,
:prefix,
:suffix,
:phone_numbers_attributes,
:addresses_attributes
# Model Associations
has_many :phone_numbers, :as => :contactable, :class_name => "PhoneNumber", autosave: true
accepts_nested_attributes_for :phone_numbers, allow_destroy: true, reject_if: :all_blan
Any help would be appreciated. Thanks!
Update:1 Also, I have tested some and realized if I leave out the phone number then it works.....if I then update using the same form and add a phone number everything works fine.

Answer 1

Nested attributes should be passed in as Array:
"user"=>{
"email"=>"test#blizzardlabs.com",
"login"=>"bgarrison",
"password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]",
"profile_attributes"=>[
{
"prefix"=>"",
"first_name"=>"Bill",
"last_name"=>"Garrison",
"suffix"=>"",
"birthday"=>"1983-06-01",
"phone_numbers_attributes"=>{
"0"=>{
"info"=>"1234567890",
"label"=>"Cell"
}
}
}
]
}

So, after a couple days of banging my head against the wall I have finally figured this out. However to understand it I need to explain my model's a bit better.
Basically, from above you can see that a User has a profile which has many phone_numbers and addresses through a polymorphic association (:as => :contactable ). However, contactable is actually a base class called ContactInformation which uses STI to contain contactable information of all types.
At one point I decided that having 4 extra fields for addresses was cluttering up the STI relationship but I still wanted to keep it. My solution was to serialize all those fields into the "info" field of ContactInformation. Right now, phone numbers only have "number" as a field that is serialized and stored into "info" but if I ever want to seperate it out into "area code" "extension" etc the implementation will be simple.
This leads to the problem. On my registration form I was using label / info for my phone_number fields instead of label / number. I had edited my edit form but not my new form (yes i know they should be the same one but I have a special ajax form for editing).
Here is the code for ContactInformation / PhoneNumber / Address
class ContactInformation < ActiveRecord::Base
attr_accessible :contactable_id, :contactable_type, :info, :label, :type
belongs_to :contactable, :polymorphic => true
end
class PhoneNumber < ContactInformation
attr_accessible :number
stash :number, in: :info
#----------------------------------Validations--Start-------------------------
validates :number, presence: true
#----------------------------------Validations--End---------------------------
end
class Address < ContactInformation
attr_accessible :street_address, :city, :state, :postal
stash :street_address, :city, :state, :postal, in: :info
#----------------------------------Validations--Start-------------------------
validates :street_address, :city, :state, :postal, presence: true
#----------------------------------Validations--End---------------------------
end
