Rails 4 Friendly Id Slug Not Updating

Question

I\'m using the following:

gem \'friendly_id\', github: \'FriendlyId/friendly_id\', branch: \'master\'

I am creating an Article section on my Ra

Answer 1

In FriendlyId 4 (Rails 3 compatible) there was a method

should_generate_new_friendly_id?

and you could define it on your model to control when slug is regenerated. Try

def should_generate_new_friendly_id?
  name_changed?
end

to regenerate slug when name changes.

EDIT

FriendlyId version 5 (Rails 4 compatible) doesn't regenerate slugs on save anymore. To restore this functionality you can either set slug column to nil before saving or use the solution provided above.

EDIT 2

You need to override the slug setter for your saves to work for Rails <5 & FriendlyId > 5 as referenced in this issue.

Add this to the model file

  def slug=(value)
    if value.present?
      write_attribute(:slug, value)
    end
  end
