# Sluggable Rails 🏅
[](https://badge.fury.io/rb/sluggable-rails)
[](https://codeclimate.com/github/juliendargelos/sluggable-rails/maintainability)
Provide a unique slug to your records, generated from the attribute of your choice.
## Usage
Use the `has_slug` method:
```ruby
# == Schema Information
#
# Table name: Post
#
# id :integer not null, primary key
# title :string
# slug :string not null
# created_at :datetime not null
# updated_at :datetime not null
#
class Post < ApplicationRecord
#...
has_slug by: :title
#...
end
```
```ruby
post = Post.create title: 'My first slugified post!'
post.slug # "my-first-slugified-post"
another_post = Post.create title: 'My first slugified post!'
another_post.slug # "my-first-slugified-post-1"
```
In this example, the slug will be generated from the post title. By default, it will be stored in the slug attribute.
You can choose another attribute to store it:
```ruby
class Post < ApplicationRecord
#...
has_slug :custom_attribute, by: :title
#...
end
```
The slug is generated with the [`parameterize` method](http://api.rubyonrails.org/v5.1/classes/ActiveSupport/Inflector.html#method-i-parameterize), you can specify a separator as it expects (default: `'-'`):
```ruby
class Post < ApplicationRecord
#...
has_slug :custom_attribute, by: :title, separator: '_'
#...
```
Obviously, you have to add the corresponding column to your schema:
```ruby
class CreatePosts < ActiveRecord::Migration[5.1]
def change
create_table :posts do |t|
t.string :title
t.string :slug, null: false, index: true, unique: true # Or your custom attribute
t.timestamps
end
end
end
```
The slug will be automatically generated in order to be unique. And a `presence` and `uniqueness` validations will also be added by the `has_slug` method.
Moreover, you can define a scope for your slug so its uniqueness will depend on other attributes:
```ruby
class Post < ApplicationRecord
#...
belongs_to :user
has_slug by: :title, scope: :user_id
# You can specify more than one attribute by giving an array of attributes to the scope option.
#...
end
```
In this example, each post will have a slug which is unique for the user it belongs to (but it could be any other attribute).
The corresponding migration would be:
```ruby
class CreatePosts < ActiveRecord::Migration[5.1]
def change
create_table :posts do |t|
t.string :title
t.references :user, foreign_key: true
t.string :slug, null: false
t.timestamps
end
add_index :posts, [:user_id, :slug], unique: true
end
end
```
