Get Started with Ruby SDK

This guide will help you get started with Contentstack Ruby SDK to build apps powered by Contentstack.

Prerequisites

  • Ruby v2.0 or later

SDK Installation and Setup

Contentstack offers two regions (US and European) as data centers to store customers' account details and data. Both regions are independent of each other and therefore have a dedicated set of instructions to use SDKs offered by Contentstack.

To use SDKs for the European region, you will have to make certain changes in the configuration of the SDK, as detailed below, and the rest of the instructions remain the same.

To use the Ruby SDK, download it using the gem install command:

$ gem install contentstack

Let's get started with the implementation.

Initialize SDK

To initialize the SDK, yYou will need to specify the stack’s API keydelivery token, and name of the environment where you will publish the content.

@stack = Contentstack::Client.new("site_api_key", "delivery_token", "enviroment_name")

For Setting the European Region:

To set European region, refer to the code below:

@stack = Contentstack::Client.new("API_key", "delivery_token", "environment_id",{"region": Contentstack::Region::EU})

Once you have initialized the SDK, you can start getting content in your app.

Basic Queries

Get a Single Entry

To get a single entry, specify the content type as well as the uid of the entry:

entry = @stack.content_type('content_type_uid').entry("entry_uid").fetch()
puts entry.get('title') # Use `get` method to retrieve field value by providing a field's unique ID

Get Multiple Entries

To retrieve multiple entries of a content type, specify the content type UID. You can also specify search parameters to filter results:

@query = @stack.content_type('blog').query
@entries = @query.where('title', 'welcome')
                 .include_schema
                 .include_count
                 .fetch
puts "Total Entries -- #{@entries.count}"
@entries.each{|entry| puts "#{entry.get('title')}" }

To retrieve localized versions of entries, you can use the query attribute:

entry = @stack.content_type('content_type_uid').query.locale('locale_code').fetch()

Note: Currently, the above query works in case of retrieving localized versions of multiple entries only.

These were examples of some of the basic queries of the SDK. For advanced queries, refer to Contentstack Ruby API reference.
