Are you tired of struggling with the ordering of subpages in Wagtail admin? Do you find yourself wondering why your pages aren’t showing up in the order you want them to? Well, wonder no more! In this article, we’ll take you by the hand and walk you through the process of specifying the ordering of subpages in Wagtail admin. By the end of this tutorial, you’ll be a pro at organizing your pages in no time.
What is Wagtail and Why Do We Need to Specify the Ordering of Subpages?
Wagtail is a popular open-source CMS (Content Management System) built on Django. It’s known for its flexibility, scalability, and ease of use. However, one of the common pain points users face is the default ordering of subpages. By default, Wagtail sorts subpages alphabetically, which might not be the desired order for your website or application.
Specifying the ordering of subpages is crucial for creating a well-organized and user-friendly website. Imagine having a blog with hundreds of articles, and you want to feature the most popular ones at the top. Without specifying the ordering, your most popular articles might get lost in the sea of other pages.
Method 1: Using the `order_by` Parameter in the Parent Page’s Model
The first method to specify the ordering of subpages is by using the `order_by` parameter in the parent page’s model. This method is ideal for simple use cases where you want to sort subpages based on a specific field.
# models.py
from wagtail.core.models import Page
class BlogIndexPage(Page):
# ...
subpage_types = ['BlogPage']
def get_subpages(self):
return BlogPage.objects.child_of(self).live().order_by('title')
In the above example, we’re using the `order_by` method to sort the subpages based on their `title` field. You can replace `title` with any field you want to sort by.
Method 2: Using a Custom Ordering Field
The second method is more flexible and powerful. You can create a custom ordering field on your page model and use it to specify the ordering of subpages.
# models.py
from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.admin.edit_handlers import FieldPanel
class BlogPage(Page):
# ...
order = models.IntegerField(null=True, blank=True)
content_panels = Page.content_panels + [
FieldPanel('order', classname="full"),
]
In this example, we’ve added an `order` field to the `BlogPage` model. We’ve also added a field panel to the page’s admin interface to allow users to input the ordering value.
To specify the ordering of subpages, you can override the `get_subpages` method in the parent page’s model:
# models.py
class BlogIndexPage(Page):
# ...
subpage_types = ['BlogPage']
def get_subpages(self):
return BlogPage.objects.child_of(self).live().order_by('order')
In this example, we’re sorting the subpages based on the `order` field. You can adjust the ordering logic to fit your needs.
Method 3: Using a Custom Sort Function
The third method is the most advanced and flexible way to specify the ordering of subpages. You can create a custom sort function that takes into account multiple factors and complex logic.
# models.py
from wagtail.core.models import Page
class BlogIndexPage(Page):
# ...
subpage_types = ['BlogPage']
def get_subpages(self):
subpages = BlogPage.objects.child_of(self).live()
return sorted(subpages, key=lambda x: (x.order, x.title))
In this example, we’re using a custom sort function that takes into account both the `order` field and the `title` field. You can modify the sort function to fit your specific needs.
Tips and Tricks
- Make sure to update your page models and run migrations after making changes to your code.
- Use the `live()` method to ensure only published pages are included in the ordering.
- Use the `child_of()` method to ensure only subpages of the current page are included in the ordering.
- You can combine multiple methods to create a more complex ordering logic.
Conclusion
Specifying the ordering of subpages in Wagtail admin is a crucial step in creating a well-organized and user-friendly website. By following the methods outlined in this article, you can take control of your page ordering and create a website that meets your specific needs.
Remember to choose the method that best fits your use case, and don’t be afraid to get creative with your ordering logic. Happy coding!
