Ruby on Rails starter project for prismic.io

This is a blank Rails project that will connect to any prismic.io repository, and trivially list its documents. It uses the prismic.io Ruby developement kit, and provides a few helpers to better use it with Rails.

Getting started

Launch the starter project

(Assuming you've installed the latest versions of Ruby, Rails and RubyGems.)

After forking and cloning the starter kit, it is immediately operational, so you can launch your rails server command. You may have to update your gems by running bundle install, but Rails will tell you about it if you must.

Configuring

By default, the starter kit uses the public API of the “Les Bonnes Choses” repository; its endpoint is https://lesbonneschoses.prismic.io/api. You may want to start by editing the config/prismic.yml file to make your Rails application use your own prismic.io repository.

To get the OAuth configuration working (and be able to preview your future content release, as well as to access your API if it's private), go to the Applications panel in your repository settings, and create an OAuth application to allow interactive sign-in. Fill the application name and the callback URL (localhost URLs are always authorized, so at development time you can omit to fill the Callback URL field), and copy/paste the clientId & clientSecret tokens into the config/prismic.yml file.

You may have to restart your Rails server.

Get started with prismic.io

You can find out how to get started with prismic.io on our prismic.io developer's portal.

Understand the Ruby development kit

You'll find more information about how to use the development kit included in this starter project, by reading its README file.

Specifics and helpers of the Rails starter project

There are several places in this project where you'll be able to find helpful helpers of many kinds. You may want to learn about them in order to know your starter project better, or to take those that you think might be useful to you in order to integrate prismic.io in an existing app.

• in app/controllers/prismic_controller.rb:
• its role: providing a module you can use as a mixin in your controllers to make it trivial to use prismic.io in your actions.
• provides the api method to instantiate your Prismic::Api object once per HTTP request.
• provides the ref method, retuning the ref id being currently queried, even if it's the master ref. To be used to call the API, for instance: api.create_search_form('everything').submit(ref).
• provides the maybe_ref method, returning the ref id being queried, or nil if it is the master ref. To be used where you want nothing if on master, but something if on another release, for instance: root_path(ref: maybe_ref).
• in app/controllers/prismic_oauth_controller.rb:
• provides all necessary controller actions to have the OAuth pages working: signin, signout, callback, …
• in config/routes.rb:
• the routes to the OAuth pages: signin, signout, callback, …
• in app/helpers/prismic_helper.rb:
• provides a basic link_resolver(ref) method to iterate upon. For a given document, the link_resolver method describes its URL on your front-office. You really should edit this method, so that it supports all the document types your content writers might link to (read the very last paragraph of our API documentation to learn more about what link_resolver is for).
• provides api, ref and maybe_ref method, just like in the PrismicController module, to be used in the views.
• …
• in config/prismic.yml : centralizes all information about the prismic.io repository's API (endpoint, client ID, client secret, …)
• in app/models/prismic_service.rb:
• provides slug_checker(document, slug), which checks a provided slug against a document.
• provides get_document(id, api, ref), which retrieves the document from its id.
• provides a number of other methods that some other helpers rely on (access_token, config, init_api, …). If you're integrating prismic.io into an existing project, you really want that file.
• in config/initializers/prismic_custom.rb:
• allows you may customize the Ruby kit's behavior here. *out-of-the-box allows you to write as_html_safe(link_resolver(maybe_ref)) in your views, instead of having to write as_html(link_resolver(maybe_ref)).html_safe.
• we've also included some basic pages by default, with their routes, controllers and views:
• the “index” page displays all documents, paginated by 20, and lists them as links towards their “document” pages.
• “document” pages display a whole document in a trivial way.
• “search” pages are search results.
• in app/views/layouts/application.html.erb, all those pages contain the necessary UI components to have the OAuth working out of the box: signing in, signing out, selectbox to change the previewed content release, …

Other technical operations

Work with a local database

You don't actually need a database to run this starter project, as prismic.io handles everything for you (content, users, …); if your website is all about content, you may never even need a database at all! Therefore, our starter project comes without ActiveRecord (the part of Rails that handles the connection with databases, and the model tier)

However, if your project offers other features than displaying content, you may need to store and retrieve non-content data from a local database. Here's how you put ActiveRecord back in your Rails starter project:

• Comment-out the 4 require statements at the top of application.rb, replace them with require 'rails/all'.
• Add the gem for the kind of database you have in mind to use (you can un-comment-out the one we left for SQLite, but we advise you to rather use the kind of database you will use in production).
• create your config/database.yml file, which entirely depends on the kind of database you'll be using. Here are exemples of usual database.yml files, but you should rather check the documentation for the database gem you're using.
• Un-comment-out the ActiveRecord::Migration.check_pending! line we left for you in test_helper.rb.
• Un-comment-out the config.active_record.migration_error = :page_load line we left for you in test_helper.rb.

Deploying your application

This starter project is immediately deployable on most hosting platforms that are compatible with Rails 4. To deploy it on Heroku, simply create a Heroku account, install the Heroku Toolbelt, and log into it by running heroku login in your terminal.

Then, go to your project's directory in your terminal, and run:

ku create
push heroku master

Now your site is live for the world to see!
