wagtail - page for showing categories; how?

I wouldl like to implement categories page using wagtail but it is quite difficult to understand for a novice programmer. When just following the tutorial of wagtail(getting started), the categories field is implemented in their official tutorial but I don't know how to get an access

For instance, in Django, If I define two models like Categories, and Posts, I can access articles that fall under a specific category using Foreign key and making a view using something like Category.posts_set.all()

But how can I do it in wagtail? Thanks for your help in advance

If you want to list all categories from e.g. a Category Index Page, then you'll need to get all categories and add them to the context. Assuming your model structure is the same as in the tutorial at https://docs.wagtail.io/en/latest/getting_started/tutorial.html#categories, then you can do

class CategoryIndexPage(Page):
    
    # ... other fields go here

    def get_context(self, request, *args, **kwargs):
        context = super().get_context(request, *args, **kwargs)
        context["categories"] = BlogCategory.objects.all()
        return context

Then in your template:

    {% if categories %}
        <h3>Categories</h3>
        <ul>
            {% for category in categories %}
                <li style="display: inline">
                    {% image category.icon fill-32x32 style="vertical-align: middle" %}
                    {{ category.name }}
                </li>
            {% endfor %}
        </ul>
    {% endif %}
