DeletedAt
Deleting data is never good. A common solution is to use default_scope
, but conventional wisdom (and for good reason) deams this a bad practice. So how do we achieve the same effect with minimal intervention. What we're looking for is the cliche "clean" solution.
DeletedAt leverages the power of SQL views to achieve the same effect. It also takes advantage of Ruby's flexibility.
Installation
Add this line to your application's Gemfile:
gem 'deleted_at'
And then execute:
$ bundle
Or install it yourself as:
$ gem install deleted_at
Usage
Using DeletedAt
is very simple. It follows a familiar pattern seen throughout the rest of the Ruby/Rails community.
class User < ActiveRecord::Base
# Feel free to include/extend other modules before or after, as you see fit...
with_deleted_at
# the rest of your model code...
end
You'll (probably) need to migrate your database for deleted_at
to work properly.
class AddDeletedAtColumnToUsers < ActiveRecord::Migration
def up
add_column :users, :deleted_at, 'timestamp with time zone'
DeletedAt.install(User)
end
def down
DeletedAt.uninstall(User)
remove_column :users, :deleted_at, 'timestamp with time zone'
end
end
Development
After checking out the repo, run bin/setup
to install dependencies. Then, run rake spec
to run the tests. You can also run bin/console
for an interactive prompt that will allow you to experiment.
