Related Pages

Using the power of Classifiers, pages can automatically show a list of similarly classified pages. By default, this is enabled on Article Pages, but can be enabled on any page via the Wagtail Admin, or a 1-line code change on the page model.

Related pages showing similarly classified articles.

Related page formatting

Each related page is rendered using the page model’s “miniview” template. The template can be overridden per model with the miniview_template attribute, the default of which is coderedcms/pages/page.mini.html.

If related pages are enabled, a QuerySet of pages is added to the context as related_pages. This QuerySet can also be retrieved by calling page.get_related_pages().

Related page customization

Each page can have related pages turned on or off via a toggle in the page editor, under the Layout tab. Pages based on CoderedArticlePage have this setting enabled by default when new pages are created. To toggle the default value when creating new pages, set related_show_default to True or False. To retroactively toggle this setting on existing pages, set the related related_show field using a manual query or migration.

By default, sibling pages are queried and ordered based on the number of Classifier Terms in common. If you wish to query a different model — for example to have Article pages show related Product pages instead — set the related_query_pagemodel attribute to the desired content type.

class ProductPage(CoderedPage):

    # Custom template that will be used when a Product
    # is shown on an Article page (below).
    miniview_template = "website/pages/product.mini.html"

class ArticlePage(CoderedPage):

    # Show related pages by default when creating new Articles.
    related_show_default = True

    # By default, related sibling Articles will be shown.
    # Show related Products instead.
    related_query_pagemodel = "website.ProductPage"

If you’d instead prefer to totally customize the related algorithm, override the get_related_pages() function. Just be sure to return a QuerySet of pages.

class ProductPage(CoderedPage):
    price = models.DecimalField(max_digits=9, decimal_places=2)

class ArticlePage(CoderedPage):

    # Show related pages by default when creating new Articles.
    related_show_default = True

    def get_related_pages(self) -> models.QuerySet:
        """Show most expensive products first."""
        return ProductPage.objects.live().order_by("-price")

Added in version 2.1: You must be on Wagtail CRX version 2.1 or higher to use related pages.
