Apostrophe 2.58.0 released: polymorphic joins! Also: responsive srcset attributes, fast forms, db reuse and more

Official Announcements
#1

2.58.0:

  • Polymorphic joins have arrived! You may now create joins like this:
{
  name: '_items',
  type: 'joinByArray',
  withType: [ 'apostrophe-blog', 'product', 'apostrophe-page' ]
}

When you join with more than one type, Apostrophe presents a chooser that allows you to pick between tabs for each type, adding in items of each type. Note that apostrophe-page can be included, so you can pick a mix of pages and pieces for the same join.

This feature is useful for creating navigation that may point to a variety of document types, without the need for an array of items with several different joins and a select element to choose between them.

Polymorphic joins work for both joinByOne and joinByArray. Currently they are not available for joinByOneReverse, joinByArrayReverse, or pieces filters. Their primary use case is creating navigation widgets.

  • apos.images.srcset helper function added. You can use this function to generate a srcset attribute for responsive display of an image. Just pass an attachment to the helper:

<img srcset="{{ apos.images.srcset(apos.images.first(data.piece.thumbnail)) }}" />

A src attribute for backwards compatibility is always advisable too.

Thanks to Fredrik Ekelund for this contribution.

  • Fast forms for big schemas are back! The issue with tags has been resolved.

  • A single MongoDB connection may be reused by several apos objects for separate sites, a feature which is exploited by the apostrophe-multisite module. Note that this only reuses the connection, it does not share a single MongoDB database. It does allow you to keep potentially hundreds of sites on a single MongoDB server or replica set, as the overhead of multiple logical “databases” is small in MongoDB’s modern WiredTiger storage engine. To reuse a connection, pass it to the apostrophe-db module as the db option.

  • Fixed a MongoDB 3.6 incompatibility in the “Apply to Subpages” feature for permissions. Also made this feature available again when removing someone’s permissions. We plan further UX work here to make this feature easier to understand and use.

  • UX fix to the “manage tags” dialog box: don’t attempt to add an empty tag. Thanks to Anthony Tarlao.

  • Warn developers if they use bad area names.

  • For those deploying asset bundles to S3: the command line task that builds an asset bundle no longer requires access to your production database, although it still needs to start up normally with access to a database in the pre-production environment where you are building the bundle.

  • Refactoring of the trash field deduplication features, in preparation to extend them to pages as well in an upcoming release.

apostrophe-workflow 2.9.4

  • When the commit option is chosen but there is no actual change to commit, don’t get hung up in the progress display. This was an issue only when accessed via a workflow dropdown menu.
