如何执行Rails“Rake任务”

what's up?

My friend created a rake task to update our data in the database (because we have db changes). Following is the task:

我的朋友创建了一个rake任务来更新数据库中的数据(因为我们有db更改)。以下是任务:

namespace :db do

  task :update_database => :environment do
    puts "Update do banco"

    posts = Post.where("source_id is null").order("id")
    done = Array.new
    posts.each do |post|
      if post.source_id.nil? and !done.include?(post)
        posts2 = Post.where("content LIKE ? AND id != ?", post.content, post.id)
        done.concat(posts2)
        posts2.each do |post2|
          post2.source_id = post.id
          post2.save
        end
      end
    end

  end
end

I already executed this rake task in my localhost, but I deploy my project to heroku and now my project won't open online. I don't remember what's the command to execute rake tasks and I can't find it in no place.

我已经在我的localhost中执行了这个rake任务,但是我将我的项目部署到heroku,现在我的项目无法在线打开。我不记得执行rake任务的命令是什么,我无法在任何地方找到它。

My questions is:

我的问题是:

1. What's the command to execute rake tasks?

执行rake任务的命令是什么?

2. What's the command to execute rake tasks on heroku? Just "heroku run "?

在heroku上执行rake任务的命令是什么?只是“heroku跑”?

Thanks!

#1

heroku run bundle exec rake db:update_database

should do.

bundle exec ensures that the script is run in the context of current bundle.

bundle exec确保脚本在当前bundle的上下文中运行。
