Rails tests trying to delete sql views

I'm trying to finish writing unit and integration tests for my app, but when I ran rake test, I see a lot of errors, all of them caused by the system trying to delete a sql view which is read only. Why is it trying to delete the view when the tests are simply to validate data creation and how do I get my tests past this? The application is working perfectly fine, but I can't get the tests to run properly. (all tests were running fine before sql views got added).

This is the error I see:

    Finished in 0.779585s, 39.7647 runs/s, 0.0000 assertions/s.

  1) Error:

  2) Error:
StaticPagesControllerTest#test_should_get_contactus:

PlayabilitySummary model:

class PlayabilitySummary < ActiveRecord::Base

self.table_name = 'playabilitysummary'
  after_initialize :readonly!

end

Playability Summary migration:

class CreatePlayabilitySummaries < ActiveRecord::Migration
  def up
    execute <<-SQL
   CREATE VIEW PlayabilitySummary AS
   SELECT date,user_id,speed,firmness,moisture FROM (((SELECT distinct(schedules.date) as date, speed.user_id as user_id, speed.speed as speed FROM schedules 
join
  (SELECT user_id, measure_date as speed_date, avg(speed) as speed FROM greens group by user_id, measure_date order by user_id, measure_date asc) as speed
on schedules.date = speed.speed_date) as avg1
JOIN
  (SELECT user_id as fuser_id, measure_date as firm_date, avg(firmness) as firmness FROM greens group by user_id, measure_date order by user_id, measure_date asc) as firmness
ON avg1.user_id = firmness.fuser_id AND avg1.date = firmness.firm_date) as avg2
JOIN
  (SELECT user_id as muser_id, measure_date as moist_date, avg(moisture) as moisture FROM greens group by user_id, measure_date order by user_id, measure_date asc) as moisture
ON avg2.fuser_id = moisture.muser_id AND avg2.date = moisture.moist_date)
      SQL
    end

def down
  execute 'DROP VIEW PlayabilitySummary'
end

end

Sample test (user_controller):

require 'test_helper'

class UsersControllerTest < ActionController::TestCase
  test "should get new" do
    get :new
    assert_response :success
  end
