Using MultiFieldPanel inside a StructBlock
If you have a StructBlock class (used inside a StreamField)... Can you still use the Wagtail panels to group some fields (eg MultiFieldPanel) and (ideally!) use the collapsible class on the panel to hide them in some kind of "Advanced" panel? I have tried adding the block.TextBlock definitions into the array for a panel the, however neither the Panel nor the Fields appeared in the form. I cant see anything in the docs about using Panels in StructBlocks: https://docs.wagtail.io/en/v2.8.1/reference/pages/panels.html https://docs.wagtail.io/en/v2.8.1/topics/streamfield.html -

Django foreignKey that doesn't use model's primary key to match to foreign object's primary key?
Lets say I have two models that look like this: ModelA uuid (primary key) id ModelB id (primary key) size I want to add a field to ModelA. I want this field to be a ForeignKey that joins on ModelA.id == ModelB.id. I've searched all throughout the Django Docs and have only found how to change the foreign object's field used in the join, but I haven't found a way to change "this" object's field used in the join. Is it possible to specify a non primary key field from "this" object that is used to create a foreign key by being joined on a matching primary key from the foreign object? -
Working pagination with filters inside URL
My pagination in HTML template looks like that: {% if items.has_other_pages %} <nav aria-label="Page navigation example"> <ul class="pagination justify-content-center"> {% if items.has_previous %} <li class="page-item"><a class="page-link" href="?page={{ items.previous_page_number }}">&laquo;</a> </li> {% else %} <li class="page-item disabled"><a class="page-link" href="#"><span>&laquo;</span></a></li> {% endif %} {% for i in items.paginator.page_range %} {% if items.number == i %} <li class="page-item active"><a class="page-link" href="#">{{ i }} <span class="sr-only">(current)</span></a></li> {% else %} <li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li> {% endif %} {% endfor %} {% if items.has_next %} <li class="page-item"><a class="page-link" href="?page={{ items.next_page_number }}">&raquo;</a></li> {% else %} <li class="page-item disabled"><a class="page-link" href="#"><span>&raquo;</span></a></li> {% endif %} </ul> </nav> {% endif %} When I enter my page my url looks like this: http://localhost:8000/bikes/all , when I use pagination without filters it looks like this http://localhost:8000/bikes/all?page=2. When I use my filters URL looks like this: http://localhost:8000/bikes/all?q=&price_from=&price_to=&cat=Gravel+Bike&bra=&size=&lab= , but when I try to use pagination with the filters, the URL goes back to http://localhost:8000/bikes/all?page=2. Any idea how to fix it so it would keep the filters on inside URL? -
