我想每天使用Heroku的scheduler重置一次数据库。
建议对调度程序使用rake任务。这就是我尝试过的:
task :reset_database => :environment do
`heroku pg:reset MY_DB:URL`
`heroku run rake db:migrate db:seed`
# some other ruby commands
end
但是我怎么能正确地做到这一点,因为将heroku命令放在反引号中,而bash normally works在这里不起作用:
No such file or directory - heroku
答案 0 :(得分:2)
尝试此rake任务:
namespace :reset_database do
desc "Destroy all table entries."
task :all => :environment do
ActiveRecord::Base.connection.tables.each do |table|
if table != 'schema_migrations'
table.singularize.camelize.constantize.destroy_all
end
# Use this if you want to use the normal seeds:
# Rails.application.load_seed
# Use this if you want to run another rake task:
Rake::Task["foo:bar"].invoke
end
end
end
