I have a model A with an after_commit callback on create and update.
class A < ApplicationRecord
after_commit :update_xyz, on: [:create, :update]
end
A rake task is in this use case. My rake task tries to create a number of model A records, but have to skip this update_xyz callback.
Is it possible to skip these callbacks while creating records? I would prefer not to add additional gems/plugins for this.
If you want a way to generally have the callback run, but at specific times be able to skip it, I usually go with this pattern:
class User < ActiveRecord::Base
attr_accessor :skip_do_something
after_save :do_something
private
def do_something
return if skip_do_something
# do work here
end
end
This way it will generally always run the do_something callback, but it's possible to skip by doing:
user = User.find 1
user.skip_do_something = true
user.save
Hope this helps.
I found a much better solution after a bit of research
https://www.rubydoc.info/github/zdennis/activerecord-import/ActiveRecord%2FBase.import
users = [User.new(name: "Test1"), ....]
User.import(users)
Doesn't invoke callbacks or validations, and much faster when the intent is to create n number of records
You can do it this way:
namespace :your_namespace do
task :your_task => :environment do
A.skip_callback(:commit, :after, :update_xyz)
//do everything you need
A.set_callback(:commit, :after, :update_xyz)
end
end
For more information, you can check this link.
You can add a condition to your callback for example, like:
class A < ApplicationRecord
after_commit :update_xyz, on: [:create, :update], unless :rake_task?
end
and defining rake_task? in some place appropriate.
