Tiny plugin for MongoMapper to cache a slugged version of a field


Either load it into all models, or individual models:

# add to all models

# add to a specific model
plugin MongoMapper::Plugins::Sluggable

Then call sluggable to configure it

sluggable :title, :scope => :account_id


Available options are:

  • :scope - scope to a specific field (default - nil)

  • :key - what the slug key is called (default - :slug)

  • :index - whether to add an index for the slug (default - true)

  • :method - what method to call on the field to sluggify it (default - :parameterize)

  • :callback - when to trigger the slugging (default - :before_validation_on_create)

  • :force - whether to reset the slug key on the sluggable feild is changed (default - false)


sluggable :title, :scope => :account_id, :key => :title_slug, :method => :to_url, :index => false

This will slug the title to the title_slug key, scoped to the account, will use String#to_url to slug it and won't add an index to the key


If an item with the same slug exists, it will add a version number to the slug.

IE assuming we already have an item with the slug of “dave”, the slug will be generated as “dave-1”

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself in another branch so I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.


$ gem install mm-sluggable
