Access programmatically generated pages via site.pages?

Preface

I’m working on a small plugin that fetches JSON data from an API, then directly creates pages for each entry

Issue

This all builds perfectly but my issue:

  • On the generated page, I can access any page variables perfectly - {{ page.foobar }}
  • On other pages, I cannot loop through the custom pages to create a list - {% for page in site.pages %}

Looking at the generator section of code, this should work but I don’t know if I am missing something.

module Jekyll
    module CUSTOM_REST_API 
        def get_data
            # This function returns an array of hashes, containing my API data
            data
        end
    end

    class CustomGenerator < Generator
        include CUSTOM_REST_API

        def generate(site)
            content = get_data
            content.each do | data |
                # SEE HERE - Add each custom page into the site.pages array to be built
                site.pages << CustomPage.new(site, site.source, 'custom', data)
            end
        end
    end

    class CustomPage < Page
        def initialize(site, base, dir, datum)
          @site = site
          @base = base
          @dir  = dir
          @name = datum["slug"] + "/index.html"

          # Set generated filepath name
          self.process(@name)

          # Use custom page layout / template
          self.read_yaml(File.join(base, '_layouts'), 'custom.html')

          # Add custom page data to each page
          self.data['title'] = datum["name"]
          self.data['category'] = "custom"
          self.data['foobar'] = datum["foobar"]
        end
      end
end

I’m assuming the generate function runs after an inventory is taken?

I believe this is the class that registers everything in site.pages, however I don’t know if this should belong here.

Recap:
I created pages from an external API using a custom plugin.
The plugin itself uses a custom generator to transform and build pages based on data.

On the data pages, I could access page data {page.custom_property}
Outside of the data pages, I could not access this data from site.pages
This is because the standard site.pages is already set by the time this generator runs.

Solution:
In my plugin, I simply added my page data to site.data instead, since it is accessible at anytime.
