# Douglas
[](https://gist.github.com/cheerfulstoic/d107229326a01ff0f333a1d3476e068d)
**Status: Rough edges are to be expected.**
Douglas is a Ruby gem that adds the ability to easily add `created_by` and
`updated_by` attributes to any ActiveRecord model.
It allows easy user-stamping for any Active Record model.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'douglas'
```
And then execute:
$ bundle
## Usage
### Built-in generator
When added in a Rails application, Douglas adds a generator which enables the users
to easily generate migrations which need to be stamped.
To generate these migrations, you can use Douglas' `table` generator:
```
rails generate douglas:table NAME
```
This will generate a migration:
```
create db/migrate/20170322225126_add_created_by_and_updated_by_to_.rb
```
The contents of this migration will be:
```ruby
class AddCreatedByAndUpdatedByTo < ActiveRecord::Migration[5.0]
def change
add_column :, :created_by, :integer, null: false
add_column :, :updated_by, :integer, null: false
add_index :, :created_by
add_index :, :updated_by
end
end
```
### Plug it into a controller
In your `ApplicationController` add a `before_action`:
```ruby
class ApplicationController
before_action :set_douglas_the_stamper
end
```
This will enable `Douglas` to know the current user that peroforms the action (create/update) on an model object.
### Use it in models
In the model (that you ran the generate task for), add this:
```ruby
class User < ApplicationRecord
has_stamps
end
```
This will populat the `created_by` and `updated_by` attributes accordintly. Under
the hood this injects callbacks that are executed before create and update.
### Use it in console
Since the `{created,updated}_by` columns cannot be `null` it means that the `Douglas.the_stamper` has to always be set to a value. This is normally done via the controller `before_filter` method, but in console you have to use the `Douglas.with_stamper` method. This method expects two arguments, an identifier of the user that does the action and a block. This means that the user will be logged as the person that has done the actions within the block.
For example:
```
>> Douglas.with_stamper(123) do
?> p = Post.first
>> p.body = 'Lorem ipsum dolor sit amet''
>> p.save
>> end
```
The `Post` will be updated, and the `updated_by` attribute will be set to the first passed argument - `123`.
## Progress
- [x] Add migrations generator (https://github.com/fteem/douglas/pull/1)
- [x] Find way to hijack `current_user` and store in `RequestStore`
- [x] Find way to plug-in `Douglas` in model lifecycle
- [ ] Improve README quality
- [ ] Add tests
- [ ] Make logged attribute (currently `id`) to be configurable
## 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.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
