# ActiveRecord::PostgresEnum
Adds migration and schema.rb support to PostgreSQL enum data types.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'activerecord-postgres_enum'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install activerecord-postgres_enum
## Usage
### Migrations
```ruby
create_enum :mood, %w(happy great been_better)
create_table :person do
t.enum :person_mood, enum_type: :mood
end
```
Running the above will create a table :person, with a column :person_mood of type :mood. This will also be saved on schema.rb so that `rake db:schema:load` works as expected.
To drop an existing enum:
```ruby
drop_enum :mood
```
To rename an existing enum:
```ruby
rename_enum :mood, :emotions
```
To add a value into existing enum:
```ruby
add_enum_value :mood, "pensive"
```
To remove a value from existing enum:
> :warning: Make sure that value is not used anywhere in the database.
```ruby
remove_enum_value :mood, "pensive"
```
To add a new enum column to an existing table:
```ruby
def change
create_enum :product_type, %w[one-off subscription]
add_column :products, :type, :product_type
end
```
To rename a value:
```ruby
rename_enum_value :mood, "pensive", "wistful"
```
**NB:** To stop Postgres complaining about adding enum values inside a transaction, use [`disable_ddl_transaction!`](https://api.rubyonrails.org/classes/ActiveRecord/Migration.html#method-c-disable_ddl_transaction-21) in your migration.
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rspec` 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).
