For a high level introduction and example Pageflow stories see

NOTE: The master branch now hosts the code for v13.x.x. Please refer to 12-x-stable branch for 12.x documentation.


For instructions on how to update from a prior version of the gem see the Updating Pageflow wiki page.


Pageflow is a Rails engine which roughly consists of the following components:

  • A full MVC stack to manage and display Pageflow stories
  • User and permission management with support for isolated accounts and user collaboration
  • A client side application for live preview editing of stories
  • Background jobs to process and encode images, audios and videos
  • Generators to quickly bootstrap a new Rails application

Pageflow assumes the following choice of libraries:


Pageflow runs in environments with:

  • Ruby >= 2.1 (see .travis.yml for supported versions)
  • Node >= 6.9.5
  • Rails 4.2
  • Redis server (for Resque)
  • A database server supported by Active Record (tested with MySQL)
  • ImageMagick

Accounts of the following cloud services have to be registered:


Generate a new Rails application using the MySQL database adapter:

$ rails new my_pageflow --database=mysql
$ cd my_pageflow

Do not name your application "pageflow" since it will cause conflicts which constant names created by Pageflow itself.

Database Setup

Enter valid MySQL credentials inside config/database.yml and create the database:

$ rake db:create

Gem Dependencies

Add these lines to your application's Gemfile, replacing X.Y.Z with the current Pageflow version number. It is recommended to depend on a specific minor version using the pessimistic version constraint operator. See Pageflow's versioning policy for details.

# Gemfile
gem 'pageflow', '~> X.Y.Z'

# The install generator sets up Resque as Active Job backend
gem 'resque', '~> 1.25'
gem 'resque-scheduler', '~> 2.5'
gem 'ar_after_transaction', '~> 0.5.0'
gem 'redis', '~> 3.0'
gem 'redis-namespace', '~> 1.5'

Run bundler to install dependencies:

$ bundle install

Running the Generator

Now you can run the generator to setup Pageflow and its dependencies:

$ rails generate pageflow:install

The generator will invoke Active Admin and Devise generators in turn and apply some configuration changes. When asked to overwrite the db/seeds.rb file, choose yes.

To better understand Pageflow's configuration choices, you can run the single steps of the install generator one by one. See the wiki page The Install Generator in Detail for more. If you'd rather not look behind the scenes for now, you can safely read on.

Database Migration

Now you can migrate the database.

$ rake db:migrate

Finally, you can populate the database with some example data, so things do not look too blank in development mode.

$ rake db:seed


Pageflow stores files in S3 buckets also in development mode. Otherwise there's no way to have Zencoder encode them. See setting up external services.

The host application can utilize environment variables to configure the API keys for S3 and Zencoder. The variables can be found in the generated Pageflow initializer.

For available configuration options and examples see the inline docs in config/initializers/pageflow.rb in your generated rails app.

Ensure you have defined default url options in your environments files. Here is an example of default_url_options appropriate for a development environment in config/environments/development.rb:

config.action_mailer.default_url_options = {host: 'localhost:3000'}

In production, :host should be set to the actual host of your application.

Running Pageflow

In addition to the Rails server, you need to start two Rake tasks for the background job processing. These tasks are listed in Procfile which is generated in the project root folder by the Pageflow installer.

Consider using the foreman gem to start all of these processes (including the Rails server) with a single command in your development environment.

The built-in Resque web server is mounted at /background_jobs. Use it to inspect the state of background jobs, and restart failed jobs. This functionality is only available for admins.


If you run into problems during the installation of Pageflow, please refer to the Troubleshooting wiki page. If that doesn't help, consider filing an issue.

Security Policy

For major security issues, at least the current release series and the last major series will receive patches and new versions.

Security related announcements will be posted to the ruby-security-ann mailing list.

If you have found a security related bug, please contact info(at) instead of creating a publicly visible issue.


Pull requests are welcome on GitHub at Everyone interacting in the project's codebases, issue trackers and mailing lists is expected to follow the code of conduct.

See the Contributing section in the guides list for instructions on how to setup your development environment. The GitHub wiki contains high level guides on common development workflows.
