Pagination in folder views

[mcasagrande18]

Insert pagination in SummaryView, TabularView, AlbumView and ListingView like in Plone Classic Theme, otherwise I can see only first 25 items in a folder.

Has this functionality been taken into consideration?

This is a problem for us too. One cannot even increase the size of batches, as defaultPageSize has no effect on folders.

I think this would make sense to add; I'm not sure about the complexity. But note that these days Volto comes with the Folder type disabled, and it's possible to use a page with the listing block, which already includes pagination.

@davisagli Using a Page instead of a Folder wouldn't fix the problem.

The idea is that the listing block behaves in two modes:

• as folder listing (in which case it uses the children items)
• querystring-based searches.

By default, when you add the listing block and don't make any changes to the Query, it acts as folder listing. Honestly, there's a lot of problems with this behavior and makes things more complicated then they should be. For example, the shape of items and querystring serialized brains is different, so if you use a Listing template that demands something beyond basic info, you can't use it as "folder contents"

@tiberiuichim Thanks for the clarification. I didn't realize that items does not use the summary serialization. I wonder if there's some way we could make it so the template can declare whether it expects the full object serialization or not.

Wouldn't it be better to use querystring, even when we don't select any criteria? See:

That would make things more standardized as well.

But the pagination is working in the listing block.

Well it works if you select some criteria. Otherwise, it doesn't really work.

@davisagli If it's for performance reasons, the variation could indicate that. See:

But the issue is in the views and not in the blocks. Then we may be talking in the wrong place :smile:
