The Response Object in Ruby
After you set up your Custom Types and have queried your content from the API, it's time to integrate that content into your templates.
First we'll go over the response object returned from the API, then we'll discuss how to access the results of the query.
The Response Object
Let’s start by taking a look at the Response Object returned when querying the API. Here is a simple example of response object with one document that contains a couple of fields.
--- !ruby/object:Prismic::Response page: 1 results_per_page: 20 results_size: 1 total_results_size: 1 total_pages: 1 next_page: nil prev_page: nil results: - !ruby/object:Prismic::Document id: WKxlPCUAAIZ10EHU uid: example-page type: page href: https://your-repo-name.prismic.io/api/documents/search?ref=WKxlPyUEEAdz..., tags:  slugs: - example-page first_publication_date: 2017-01-13 11:45:21.000000000 +00:00 last_publication_date: 2017-02-21 16:05:19.000000000 +00:00 lang: en-us alternate_languages: fr-fr: !ruby/object:Prismic::AlternateLanguage id: WZcAEyoAACcA0LHi uid: example-page-french type: page lang: fr-fr fragments: title: !ruby/object:Prismic::Fragments::StructuredText blocks: - !ruby/object:Prismic::Fragments::StructuredText::Block::Heading text: Example Page spans:  label: level: 1 date: !ruby/object:Prismic::Fragments::Date value: 2017-01-13 00:00:00.000000000 +01:00
At the topmost level of the response object, you mostly have information about the number of results returned from the query and the pagination of the results.
Note that when using certain helper functions such as getSingle(), getByUID(), or getByID(), the results will automatically be returned.
The Query Results
The actual content of the returned documents can be found under "results". This will always be an array of the documents, even if there is only one document returned.
Let’s say that you saved your response object in a variable named "response". This would mean that your documents could be accessed with the following:
And if you only returned one document, it would be accessed with the following:
Each document will contain information such as its document ID, UID, type, tags, slugs, first publication date, & last publication date.
The content for each document will be found inside "fragments". In the example above you have title and date.
Content Field Helper Functions
The Ruby development kit provided by prismic.io comes with helper functions that make it easy to retrieve the content for each content field type.
These will all look something like the following.
In the case above, "page" is the API-ID of the Custom Type and "illustration" is the API-ID of the image field.
The helper functions available for each content field are shown on their individual templating pages.
