我想完成爲我的應用編寫單元和集成測試,但是當我運行耙測試時,我看到很多錯誤,所有這些都是由系統嘗試刪除這是隻讀的SQL視圖。爲什麼當測試只是爲了驗證數據創建以及如何讓我的測試過去時,它試圖刪除視圖?該應用程序工作得很好,但我無法讓測試正常運行。 (在添加sql視圖之前,所有測試都正常運行)。Rails測試試圖刪除sql視圖
這是我看到的錯誤:

1) Error:
UsersControllerTest#test_should_get_new:
ActiveRecord::StatementInvalid: PG::ObjectNotInPrerequisiteState: ERROR: cannot delete from view "playabilitysummary"
DETAIL: Views that do not select from a single table or view are not automatically updatable.
HINT: To enable deleting from the view, provide an INSTEAD OF DELETE trigger or an unconditional ON DELETE DO INSTEAD rule.

Error:

2) Error:
StaticPagesControllerTest#test_should_get_contactus:
ActiveRecord::StatementInvalid: PG::ObjectNotInPrerequisiteState: ERROR: cannot delete from view "playabilitysummary"
DETAIL: Views that do not select from a single table or view are not automatically updatable.

: DELETE FROM "playabilitysummary"
PlayabilitySummary模型:
class PlayabilitySummary < ActiveRecord::Base
self.table_name = 'playabilitysummary'
after_initialize :readonly!
end
可玩性摘要遷移:
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
樣品測試(user_controller):
require 'test_helper'
class UsersControllerTest < ActionController::TestCase
test "should get new" do
get :new
assert_response :success
end
end
謝謝,這裏有一篇文章解釋瞭如何做到這一點https://rietta.com/blog/2015/03/30/adding-rake-db-views-for-sql-views-to-a- rails-project /但我仍然得到相同的錯誤 – agusgambina
