Jekyll excludes tag from pagination

Question

I have posts with tags fooand I want to exclude them from my first page.

I tried putting this code in the first page template:

<div class="posts">
  {% for post in paginator.posts %}
  {% unless post.tags and post.tags contains "foo" %}

  {% endunless %}
  {% endfor %}
</div>

However, this leads to incorrect page breaks.

Here are some sample messages:

+-------+--------+-----+
| Index |  Post  | Tag |
+-------+--------+-----+
|     1 | Red    | foo |
|     2 | Blue   |     |
|     3 | White  |     |
|     4 | Pink   | foo |
|     5 | Orange |     |
|     6 | Yellow | foo |
|     7 | Beige  | foo |
|     8 | Purple |     |
|     9 | Black  | foo |
+-------+--------+-----+

Actual conclusion:

• Page 1: 2, 3, 5
• Page 2: 8

What I would like:

• Page 1: 2, 3, 5, 8

As you can see, the column is currently split into 5 and then my code filters them - I would like to apply filtering before pagination is calculated.

Answer 1

This cannot be done without hacking the paginator plugin, so we go:

• remove gem jekyll-paginatefromGemfile

• _config.yml:

   paginate: 2
   paginate_path: "/blog/page:num/"
  

• _plugins

• pager.rb pagination.rb _plugins/

   cd _plugins
   wget https://github.com/jekyll/jekyll-paginate/blob/master/lib/jekyll-paginate/pager.rb
   wget https://github.com/jekyll/jekyll-paginate/blob/master/lib/jekyll-paginate/pagination.rb
  

• ,

  <!-- This loops through the paginated posts -->
  {% for post in paginator.posts %}
    <h1><a href="{{ post.url }}">{{ post.title }}</a></h1>
    <p class="author">
  <span class="date">{{ post.date }}</span>
    </p>
    <div class="content">
  {{ post.content }}
    </div>
  {% endfor %}
  
  <h1>  Paginator</h1>
  <!-- Pagination links -->
  <div class="pagination">
    {% if paginator.previous_page %}
  <a href="{{ paginator.previous_page_path }}" class="previous">Previous</a>
    {% else %}
  <span class="previous">Previous</span>
    {% endif %}
    <span class="page_number ">Page: {{ paginator.page }} of {{ paginator.total_pages }}</span>
    {% if paginator.next_page %}
  <a href="{{ paginator.next_page_path }}" class="next">Next</a>
    {% else %}
  <span class="next ">Next</span>
    {% endif %}
  </div>
  

• pagination.rb paginate, , foo, all_posts , , :

         all_posts = all_posts.select do |elem|
           !elem.data['tags'].include? 'foo'
         end
  

  :

       def paginate(site, page)
         all_posts = site.site_payload['site']['posts'].reject { |post| post['hidden'] }
         all_posts = all_posts.select do |elem|
           !elem.data['tags'].include? 'foo'
         end
         pages = Pager.calculate_pages(all_posts, site.config['paginate'].to_i)
         (1..pages).each do |num_page|
           pager = Pager.new(site, num_page, all_posts, pages)
           if num_page > 1
             newpage = Page.new(site, site.source, page.dir, page.name)
             newpage.pager = pager
             newpage.dir = Pager.paginate_path(site, num_page)
             site.pages << newpage
           else
             page.pager = pager
           end
         end
       end
