Build Status

Manages permalink field on an ActiveRecord model to be used in place of the id field in Rails.

Kevin McPhillips (github@kevinmcphillips.ca)

Installation

Using bundler, add to the Gemfile:

gem 'acts_as_permalink'

Or stand alone:

$ gem install acts_as_permalink

Requirements

  • Ruby 2.0 or higher
  • Rails 4.0 or higher

Usage

This gem works with ActiveRecord, and by convention looks for a title method and a permalink string field on the model:

And then just call it in your model:

class Post < ActiveRecord::Base
  acts_as_permalink
end

You can then use your link helpers normally:

post_path(@post) # "/post/the_name_of_post_here"

The title and permalink fields can be overridden with the following options:

from:          :title       # Name of the active record column or function used to generate the permalink
to:            :permalink   # Name of the column where the permalink will be stored
max_length:    60           # Maximum number of characters the permalink will be
underscore:    false        # Prefer using the `_` character as a replacement over the default `-`
scope:         nil          # Make the permalink unique scoped to a particular attribute
allow_update:  false        # Allow the permalink column to be updated

So, for example you have want to store your permalink in a column called path_name and you want to generate your permalink using first and last name, and you want to restrict it to 40 characters, and scope the permalink by organization, your model would look like:

class User < ActiveRecord::Base
  acts_as_permalink from: :full_name, to: :path, max_length: 40, scope: :organization_id

  belongs_to :organization

  def full_name
    [first_name, last_name].join(" ")
  end
end

Permalinks can be generated using String#to_permalink like so:

"Hello, world!".to_permalink
> "hello_world"

And the patch to string can be avoided by doing a require: "base" in the Gemfile of the application. Conversion is always available through:

Acts::Permalink::Conversion.convert("Hello, world!")
> "hello_world"

Tests

$ bundle exec rspec
