Routable Page Categories And Years
This is a continuation post from the original Routable Page Mixin tutorial. This time we'll add URL parameters and filter pages based on a custom route.
Below is the code you can use. Please note, it's purposely not complete. I didn't handle missing categories in the try/except block — that's for you to use as needed and replace with what your application needs.
class BlogListingPage(RoutablePageMixin, Page): # ... fields and panels here @route(r"^year/(\d+)/(\d+)/$", name="blogs_by_year") def blogs_by_year(self, request, year=None, month=None): context = self.get_context(request) # Implement your BlogDetailPage filter. Maybe something like this: # if year is not None and month is not None: # posts = BlogDetailPage.objects.live().public().filter(year=year, month=month) # else: # # No year and no month were set, assume this is july-2019 only posts # posts = BlogDetailPage.objects.live().public().filter(year=2019, month=07) # print(year) # print(month) # context["posts"] = posts # Note: The below template (latest_posts.html) will need to be adjusted return render(request, "blog/latest_posts.html", context) @route(r"^category/(?P<cat_slug>[-\w]*)/$", name="category_view") def category_view(self, request, cat_slug): """Find blog posts based on a category.""" context = self.get_context(request) try: # Look for the blog category by its slug. category = BlogCategory.objects.get(slug=cat_slug) except Exception: # Blog category doesnt exist (ie /blog/category/missing-category/) # Redirect to self.url, return a 404.. that's up to you! category = None if category is None: # This is an additional check. # If the category is None, do something. Maybe default to a particular category. # Or redirect the user to /blog/ ¯\_(ツ)_/¯ pass context["posts"] = BlogDetailPage.objects.live().public().filter(categories__in=[category]) # Note: The below template (latest_posts.html) will need to be adjusted return render(request, "blog/latest_posts.html", context)
