Rails - Sep 2013 - Strong parameters with has_many gives “no implicit conversion of Symbol into Integer”

Trying to create a user from a json request but my server gives me 
"typeError (no implicit conversion of Symbol into Integer)". I
understand
that it''s something wrong with my nested attribute but i dont know
what,
this''s driving me crazy..

My Javascript file:
> user = {
>     email: @get(''email'')
>     first_name: @get(''firstName'')
>     last_name: @get(''lastName'')
>     password: @get(''password'')
>     password_confirmation: @get(''passwordConfirmation'')
>     registration_completed: true
>
>     authentications_attributes: {
>         provider: @get(''provider'')
>         uid: @get(''uid'')
>     }}
>
> $.post("/api/users", { user })
>
>
Params:
 

name, :last_name, :email, :password, :password_confirmation,
:registration_completed, authentications_attributes: [:id, :user_id, :provider,
:uid])

Console:

Started POST "/api/users" for 127.0.0.1 at 2013-09-20 15:39:49

Create method:

def create      
    @user = User.new(user_params)
    @user.authentications.build
    authorize! :create, @user

    if @user.save 
      render json: { user: { id: @user.id, auth_token: @user.session_api_key }
}, status: 201
    else
      render json: { errors: @user.errors.messages }, status:
:unprocessable_entity
    end 

end 

What am I doing wrong? And of course have i "accepts_nested_attributes_for 
:authentications" in my User.rb file. Thanks!

in general that errors means that something is trying to use an array as a 
hash, ie passing a non integer key to []

be of
the form

[ {''provider'' => ''facebook'', ...} ]

or (since you can''t really do arrays of hashes when using regular forms

{
  ''123456'' => {''provider'' =>
''facebook'', ...},
  ''456789'' => {''provider'' =>
''google'', ...}
}

The keys in that hash are arbitrary. It''s common to use the current
time in
milliseconds - anything that is unique is good enough
