Question

我正在使用heroku来部署我的rails应用程序。我试图通过运行命令heroku run rake db:seed在生产中播种一些数据。但是，该命令不起作用。我无法在生产中播种文件。 seeds.rb文件如下所示。

# This file should contain all the record creation needed to seed the database with its default values.
# The data can then be loaded with the rake db:seed (or created alongside the db with db:setup).
#
# Examples:
#
#   cities = City.create([{ name: 'Chicago' }, { name: 'Copenhagen' }])
#   Mayor.create(name: 'Emanuel', city: cities.first)

# end


    5.times do              
    Scoreboard.create!(name_of_scoreboard: "scoreboard_abc",
                      name_of_organization: "abcdef",
                      name_of_activity: "ghijklmn",
                      user_id: 1,
                      states: "state",
                      country: "state",
                      cities: "state")
    end

运行命令时终端中收到以下消息。

 $ heroku run rake db:seed
    Running rake db:seed on ⬢ app... up, run.4751
      ActiveRecord::SchemaMigration Load (2.0ms)  SELECT "schema_migrations".* FROM "schema_migrations"

I run `heroku restart` but the objects isn't seeded in the production database. I have tried seeding this file in development and it works perfectly. I am not sure what's wrong. 

running heroku run rake db:setup gives me the following error

我想我正在运行已经存在的迁移文件。结果，我得到了一个唯一性错误。

Answer 1

我认为您有待迁移的迁移。你可以尝试：

Heroku run rake db:migrate db:seed

Answer 2

尝试以下步骤

heroku run rake db:schema:load
heroku run rake db:migrate
heroku run rake db:seed

无法使用heroku在生产数据库中播种数据
