Rails API - RSPEC Factory Girl Stack Level Too Deep?

Encountering the following error and have been reading extensively on the stack level too deep error. I am using Ruby 1.9.3-p392, Rails 4.1.4 and Rspec-core 3.1.7 and factory girl rails 4.5 for my dev environment. I've found that some people are 'creating an infinite loop' so I've systematically commented out code to see what other errors I return, but am totally stuck.

1) POST /v1/notes/id saves the lat, lon, note text, note photo, recipients, and expiration
     Failure/Error: Unable to find matching line from backtrace
     SystemStackError:

Here's my spec:

describe 'POST /v1/notes/id' do
  it 'saves the lat, lon, note text, note photo, recipients, and expiration' do
    date = Time.zone.now
    devicetoken = '123abcd456xyz'
    user = create(:user, devicetoken: devicetoken)

  post '/v1/notes', {
    user_id: user.id,
    devicetoken: user.devicetoken,
    lat: 5.5,
    lon: 3.3,
    note_text: 'Hey sweetie! Just thinking about your lovely face!',
    photo_uri: 'http://www.photour/l12345.jpg',
    expiration: date,
  }.to_json, {'Content-Type' => 'application/json' }

  note = Note.last
  expect(response_json).to eq({ 'id' => note.id })
  expect(note.lat).to eq (5.5)
  expect(note.lon).to eq(3.3)
  expect(note_text).to eq('Hey sweetie! Just thinking about your lovely face!')
  expect(note.photo_uri).to eq('http://www.photour/l12345.jpg')
  expect(note.expiration.to_i).to eq date.to_i

  end
end

Here's my factories

User

FactoryGirl.define do
  factory :user do
    first "MyString"
    last "MyString"
    email "MyString"
    username "MyString"
    pw "MyString"
    devicetoken "MyString"
  end
end

Notes

FactoryGirl.define do
  factory :note do
    user_id 1
    note_text "MyText"
    lat 1.5
    lon 1.5
    photo_uri "MyString"
    expiration Time.zone.now.utc
  end
end

Here's the controller code:

def note_params
  { 
    user_id: user.id,
    devicetoken: user.devicetoken,
    lat: params[:lat],
    lon: params[:lon],
    note_text: params[:note_text],
    photo_uri: params[:photo_uri],
    expiration: params[:expiration]
  }
end

def user
  User.find_or_create_by(user_id: user.id)
end

Here's the Note model - do I need a validation for the uniqueness of the device token here?:

class Note < ActiveRecord::Base
  validates :user_id, presence: true
  validates :note_text, presence:true 
  validates :lat, presence: true 
  validates :lon, presence: true
  validates :expiration, presence: true

  belongs_to :user, foreign_key: 'user_id', class_name: 'User'
end

Your user method

def user
  User.find_or_create_by(user_id: user.id)
end

Will recurse infinitely - I assume you meant to pass the user_id from the params.

It also seems unlikely that find_or_create_by is the right method to use - typically if you have a user id then you'd just use find
