Change the unique generated title names of friendly-id - ruby-on-rails

Question

I am using the friendly_id gem. In the portfolio.rb I placed these two lines:
extend FriendlyId
friendly_id :title, use: :slugged
As you can see I am also using the slug option. When I create a project with title "example" it works find and I can find the project under mysite.com/projects/example. Now, if I create a second one with the same title I get a title for it like this one: mysite.com/projects/example-74b6c506-5c61-41a3-8b77-a261e3fab5d3. I don't really like this title. I was hoping for a friendlier title like example-2.
At this question, RSB (user) told me that its friendly_id that causes that. I was wondering if there is a way to create a more friendly. At first I thought of "manually" checking if the same title exists (in a while loop) and assigning another title using either example-2 or example-3 or... example-N.
However do I need to do something like that or am I missing something? Is there an easier way to do something like that?

Answer 1

Check the documentation for the latest version of friendly_id:
A new "candidates" functionality which makes it easy to set up a list of alternate slugs that can be used to uniquely distinguish records, rather than appending a sequence.
Example straight from the docs:
class Restaurant < ActiveRecord::Base
extend FriendlyId
friendly_id :slug_candidates, use: :slugged
# Try building a slug based on the following fields in
# increasing order of specificity.
def slug_candidates
[
:name,
[:name, :city],
[:name, :street, :city],
[:name, :street_number, :street, :city]
]
end
end

Answer 2

UUID
The problem you're alluding to is the way in which friendly-id appends a hash (they call it a UUID) to duplicate entries:
Now that candidates have been added, FriendlyId no longer uses a
numeric sequence to differentiate conflicting slug, but rather a UUID
(e.g. something like 2bc08962-b3dd-4f29-b2e6-244710c86106). This makes
the codebase simpler and more reliable when running concurrently, at
the expense of uglier ids being generated when there are conflicts.
I don't understand why they have done this, as it goes against the mantra of friendly ID, but nonetheless, you have to appreciate that's how it works. And whilst I don't think the slug_candidates method above will prove any more successful, I do think that you'll be able to use something like a custom method to define the slug you wish

You'll want to read this documentation (very informative)
It says there are two ways to determine the "slug" your records are assigned, either by using a custom method, or by overriding the normalize_friendly_id method. Here's my interpretation of both of these for you:
Custom Method
#app/models/project.rb
Class Project < ActiveRecord::Base
extend FriendlyID
friendly_id :custom_name, use: :slugged
def custom_name
name = self.count "name = #{name}"
count = (name > 0) ? "-" + name : nil
"#{name}#{count}"
end
end
Normalize_Friendly_ID
#app/models/project.rb
Class Project < ActiveRecord::Base
extend FriendlyID
friendly_id :name, use: :slugged
def normalize_friendly_id
count = self.count "name = #{name}"
super + "-" + count if name > 0
end
end
