PG::UndefinedTable: ERROR: relation "services" does not exist LINE 1: SELECT "services".* FROM "services"

Question

I have some trouble using the whenever gem. I create a rake task which is working perfectly fine when I launch it myself BUT when I try to automate it with whenever I got the following message in my log:

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR:  relation "services" does not exist
LINE 1: SELECT "services".* FROM "services"
                                 ^
: SELECT "services".* FROM "services"

Is this a naming issue ? I check and double check but did I miss something?

my environment is development.

Here is my 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

and my schema:

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

here is my models: - service.rb

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

• ping.rb

  class Ping < ApplicationRecord belongs_to :service end

Answer 1

So I found where the problem was thanks to your comments.

Cron is sending this:

/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'

As you can see, he is sending it to the production environment, even if in my schedule:

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

I'm telling him to send it to the development environment. I need now to find a way to force him to go in that environment as when i run:

/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'

it works

I updated cronjob environment with:

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

and now it's working smoothly
