Soft Delete
In a production app, you should probably never really delete anything.
A soft-delete marks a record as deleted, and keeps it in the database for historical reference.
Installation
Add this line to your application's Gemfile:
gem "soft_delete-workbar", require: "soft_delete"
And then execute:
$ bundle
Or install it yourself as:
$ gem install soft_delete-workbar
Usage
Safely "delete" records from your database without losing them permanently.
- Add SoftDelete to a model
class MyModel < ActiveRecord::Base include SoftDelete end
- Add a
deleted_at
column to the model's database tablerails g migration AddSoftDeleteToMyModels deleted_at:timestamp
- Safely call
MyModel#delete
without losing the record forever
Methods
Please see the SoftDelete
module and the associated tests for a description of
the methods that will be added to your model.
-
.not_deleted
- records without a deleted_at timestamp -
.deleted
- records with a deleted_at timestamp -
#delete
- set the deleted_at timestamp -
#delete!
- delete the record from the database -
#destroy
- set the deleted_at timestamp, and run callbacks -
#destroy!
- delete the record from the database, and run callbacks -
#restore
- set the deleted_at timestamp to nil
It will be necessary to exclude deleted records when querying the model.
Use the not_deleted
scope that now exists on the model.
class MyModelsController < ApplicationController
def index
@my_models = MyModel.not_deleted
end
end
