Rake task that purge just a single table


Rake task that purge just a single table

Hope that helps Is there a Rake command that i can run that would just delete all the fields of a table instead of dropping the whole database and recreating it. I have a table that grows large very quick, most of the data in it does not need to persist more that a week. , Try truncating the table:
code :
ActiveRecord::Base.connection.execute("TRUNCATE TABLE table_name")

how to write a rake task to bundle install then rake db:migrate then rake db:seed?

it should still fix some issue How to write a rake task that will bundle install then rake db:migrate then rake db:seed. , This should work but consider using Capistrano/Chef for deployment:
code :
namespace :install do
  task :db_reset do
    # bundle install - I do not believe attempting this in a rake file
    # is recommended as one would need to ensure it is run in your application
    # directory and rvm has loaded correct version of ruby/gemsets (.rvmrc required)
    Rake::Task['db:migrate'].invoke
  end
end
bundle install && bundle exec rake db:migrate && bundle exec rake db:seed

around this issue It's task (i.e. a method), not Task (i.e. a class). You have to define your task like
code :
task :sayHello do
    puts "Hello World"
end

I wish this help you You should follow the Sidekiq documentation and get it setup for Heroku.
One you have Sidekiq running, I recommend the following architecture:
code :
# rake contact:nightly_sync_list
namespace :contacts do
  desc "Test Rake Task"
  nightly_list_sync: :environment do
    ContactListWorker.perform_async
  end
end

class ContactListWorker
  require 'net/ftp'
  include Sidekiq::Worker

  def perform()
    sftp = Net::SFTP.start('ftp.test.com','luigi', :password => 'pass_word')
    records = sftp.download!("luigi/list.xml")
    records_hash = Hash.from_xml(records)
    records_hash['Report']['Details'].each {|record| ContactWorker.perform_async(record) }
  end
end

class ContactWorker
  include Sidekiq::Worker

  def perform(record)
    contact = Contact.create(
      first_name: record['FirstName'],
      last_name: record['LastName'],
      date_of_birth: record['DateofBirth']
    )
    if contact.valid?
      puts "Created contact"
    else
      puts "Invalid contact"
    end
 end

this one helps. Yes, it looks like you've found a bug in the newly-released Capistrano 3.6.0. Please report the bug here: https://github.com/capistrano/capistrano/issues
The underlying problem is that Capistrano 3.6.0 is (mistakenly) incompatible with Rake < 11.0.0.

Hope that helps If it is not too big of a refactor, I would go with your first option 1) to set type to Restream::Periscope and not periscope primarily just because it is the Rails convention.
If option 1) is implemented, you said your other concern about this which is that Restream::Periscope.find_each will no longer return records of the other "types" and will be automatically filtered accordingly depending on the subclass... does makes sense because your .find_each is querying upon Restream::Periscope, and thus it is intuitive that I will be expecting that all of the returned records will be of type "Restream::Periscope".
code :
Restream::Service.find_each(type: old_restream_custom.type)
# or
Restream::Service.create(type: old_restream_custom.type)
