# str_enum

Don’t like storing enums as integers in your database? Introducing...

String enums for Rails!! :tada:

- scopes
- validations
- accessor methods

## Getting Started

Add this line to your application’s Gemfile:

```ruby
gem 'str_enum'
```

Add a string column to your model.

```ruby
add_column :users, :status, :string
```

And use:

```ruby
class User < ActiveRecord::Base
  str_enum :status, [:active, :archived]
end
```

The first value will be the initial value. This gives you:

#### Scopes

```ruby
User.active
User.archived
```

#### Validations

```ruby
user = User.new(status: "unknown")
user.valid? # false
```

#### Accessor Methods

```ruby
user.active?
user.archived?
```

#### Forms

```erb
<%= f.select :status, User.statuses.map { |s| [s.titleize, s] } %>
```

## Options

Choose which features you want with:

```ruby
class User < ActiveRecord::Base
  str_enum :status, [:active, :archived], scopes: false, validate: false, accessor_methods: false
end
```

Prevent method name collisions with the `prefix` option.

```ruby
class User < ActiveRecord::Base
  str_enum :address_status, [:active, :archived], prefix: :address
end

# scopes
User.address_active
User.address_archived

# accessor methods
user.address_active?
user.address_archived?
```
