Question

我正在尝试在单个任务中执行多个rake任务。所有rake任务都用于更新各个表的列。例如如果health_post_id> 100000 删除该记录

现在我需要通过命令行传递100000作为参数。但我无法弄明白这是代码

if Rails.env.development? or Rails.env.test?
 namespace :clear_data do


  desc 'clear time slots'
  task :clear_time_slots => :environment do
    TimeSlot.where('health_post_id > ?', p).each do |time_slots|
      time_slots.destroy
    end
  end

  desc "Clean the Practices table"
  task :clear_practice_records => :environment do
      Practice.where('health_post_id > ?', p).each do |practices|
        practices.destroy
      end
  end


  desc "clean database"
  task :clear_database => :environment do |p|
    Rake::Task['clear_data:clear_practice_records'].execute
    Rake::Task['clear_data:clear_time_slots'].execute


    end



 end
 end

我不太确定，但我想你应该可以做到：

if Rails.env.development? or Rails.env.test?
 namespace :clear_data do
  desc 'clear time slots'
  task :clear_time_slots, [:post_id] => :environment do |_, args|
    TimeSlot.where('health_post_id > ?', args[:post_id]).destroy_all
  end

  desc "Clean the Practices table"
  task :clear_practice_records, [:post_id] => :environment do |_, args|
    Practice.where('health_post_id > ?', args[:post_id]).destroy_all
  end


  desc "clean database"
  task :clear_database, [:post_id] => :environment do |_, args|
    max = args[:post_id]
    Rake::Task['clear_data:clear_practice_records'].execute(post_id: max)
    Rake::Task['clear_data:clear_time_slots'].execute(post_id: max)

    #OR

    #Rake::Task['clear_data:clear_practice_records'].invoke(max)
    #Rake::Task['clear_data:clear_time_slots'].invoke(max)
  end
 end
end

在Ruby on Rails中将参数传递给rake任务
