PG :: UndefinedTable：錯誤：關係「services」不存在LINE 1：SELECT「services」。* FROM「services」

使用when gem時遇到了一些麻煩。我創造當我啓動它自己這是工作完全正常rake任務，但是當我試圖把它與每當我在我的日誌中看到以下消息自動化：PG :: UndefinedTable：錯誤：關係「services」不存在LINE 1：SELECT「services」。* FROM「services」

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "services" does not exist

這是一個命名的問題？我檢查並仔細檢查，但是我錯過了什麼？

我的環境是發展。

這裏是我的schedule.rb：

set :output, {:error => "log/cron_error_log.log", :standard => "log/cron_log.log"} 
every 2.minutes do 
    rake 'check:all', :environment => 'development' 
end

和我的架構：

ActiveRecord::Schema.define(version: 20170922073721) do 

    enable_extension "plpgsql" 

    create_table "pings", force: :cascade do |t| 
    t.boolean "up" 
    t.integer "service_id" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    t.index ["service_id"], name: "index_pings_on_service_id", using: :btree 
    end 

    create_table "services", force: :cascade do |t| 
    t.string "name" 
    t.string "web_api" 
    t.string "json_path" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    add_foreign_key "pings", "services" 
end

這裏是我的模型： - service.rb

class Service < ApplicationRecord 
    has_many :pings, dependent: :destroy 
    validates :name, uniqueness: true, presence: true 
    validates :web_api, uniqueness: true, presence: true 
end

平.rb

類平< ApplicationRecord belongs_to的：服務結束

你可以添加你的模型@Doge？ –

我認爲每當創建的cron作業都無法訪問相同的一組gem（儘管它應該正常運行，然後呢？）。你可以嘗試使用cron作業使用的相同bash運行rake任務嗎？ – ulferts

@SebastiánPalma只是，謝謝 – Doge

所以，我發現那裏的問題是感謝您的意見。

cron是發送此：

/bin/bash -l -c 'cd /Users/Naekh/code/yoando/statuschecker/statuschecker && RAILS_ENV=production bundle exec rake check:all --silent >> log/cron_log.log 2>> log/cron_error_log.log'

正如你可以看到，他把它發送到生產環境中，即使在我的日程表：

set :output, {:error => "log/cron_error_log.log", :standard => "log/cron_log.log"} 
every 2.minutes do 
    rake 'check:all', :environment => 'development' 
end

我告訴他送它到了開發環境。我現在需要找到一種方法來迫使他在該環境中去，因爲當我運行：

/bin/bash -l -c 'cd /Users/Naekh/code/yoando/statuschecker/statuschecker && RAILS_ENV=environment bundle exec rake check:all --silent >> log/cron_log.log 2>> log/cron_error_log.log'

它的工作原理

我更新的cronjob環境：

whenever --update-crontab --set environment='development'

，現在它的工作順利
