Is it possible to filter all collections at once?

[nhoizey]

I'm using Forestry to edit content for a site generated with Eleventy, and it manages drafts with a YFM variable named published with values false and true.

I would like to filter out all drafts, but it currently requires defining all collections one after the other in .eleventy.js and filter out the items that have published: false:
nhoizey/precious-prana.com@19d20ec

Every time I had a collection, I will have to remember adding this.

Is there a simpler way?

Use this gist to filter the array by key:value pair at the point of setting the collection in the template language. Tested to work with nunjucks and liquid.

@danfascia sorry, I don't understand how to use it, could you link to an usage example? thanks

@nhoizey This filter is used by @paulrobertlloyd to select elements from a collection

Maybe not quiet what you're looking for, as you don't wan't those elements listed in your collection at all if I understand. You might want to filter drafts in the collection like @rem does. It's quiet similar to what you do.

From what I understand, you want to make it a function you could use in all your collections?

As an aside, if you are using Liquid for templating, it’s builtin where filter would achieve the same as my custom filter. However 11ty depends on an earlier version of LiquidJS, which doesn’t support this feature.

@paulrobertlloyd I'm using Nunjucks… 😅

@DirtyF I would like to filter draft content out of all collections without having to define collections in .eleventy.js at all, so it looks like that's not what @Rem does.

Maybe @danfascia's solution but inverted (doesnt_contain instead of contains) would be a way, pretty similar to @paulrobertlloyd 's where.
