PW 3.0.95 – Core updates

[ryan]

This week we take a look at something really cool we added a few months ago but haven’t told you about yet: owner selectors. We also take a brief look at what’s new in ProcessWire 3.0.95 and and the status of our next master version, which is just about ready!

Ryan, great work, as always, on the "owner" selection! Very cool stuff!! I'm eager to use it someday!

option 1: w/ 'owner' selector (as mentioned in blog post)

$items = $pages->find(
  "template=architect, " .
  "architects.owner.parent.name=atlanta, " .
  "architects.owner.height>1000"
);

option 2: w/o 'owner' selector (2 queries required)

$architects = new PageArray();
foreach($pages->find("template=building,height>1000,parent.name=atlanta") as $building) {
  $architects->add($building->architects);
}

option 3: w/o 'owner' selector but requires a bi-directional relationship field called 'buildings' on the 'architect' template (using the bi-directional approach or possibly PagefieldPairs, or ConnectPageFields):

$pages->find("parent=/architects/,template=architect,buildings.parent.name=atlanta,buildings.height>1000");

Hopefully that de-mystifies it.  I come across this brain twister once in a while.

Know exactly what you mean! I had something similar a couple of years ago and did find a kinda solution, but was never happy with it. Just hope I remember about this next time the need arises.

Cool  stuff @ryan!

Are there any chances this could be implemented for Table and TableRows? Would be great to have it there too.
