has_parent=1 includes 'home'?

[theo]

Hello

Can anybody explain, why the result of the selector "has_parent=1" includes 'home'?

$homes=$pages->findIDs("has_parent=1");
echo $pages->get($homes[0])->name; //returns 'home'

I would expect that 'home' is not a parent of itself.

Thank you.

No idea - just the observation that the result is the same when you use $pages->find() with the $options parameter like this:

$options = array('findIDs'=>1);
$homes=$pages->find("has_parent=1", $options);
echo $pages->get($homes[0])->name; //returns 'home'

Not sure as well, but maybe has something to do with '/' being the only saved page with a NullPage as a parent?

echo print_r($pages->get('/'));

// result 
// ProcessWire\NullPage Object ( ... )

And in the database, home's parent_id is 0, and it does not have an entry in pages_parents. Upon further digging, I also found that home is the only result when querying for "has_parent!=1", and it is hard-coded. 

Anyway, if you require home to not be in the result, maybe just exclude it from the query?

$childrenOfHome = $pages->find("has_parent=1, id!=1");

@alxndre Sure it is not really a problem, once you know how it works.

For my case this does what I want:

$pages->find("id!=1,has_parent!=2");

Meaning: all, except home and everything under admin (For logged in admins).

But still, such little uncertainties can diminish confidence in the system.

I think that is something that should be reported. 

Could you open an issue on Github, so Ryan could comment is it intended behavior or a bug?

This has always been the case as far as I can remember. Similar to rootParent of home:

$h = $pages->get(1);
echo $h->rootParent->id;// outputs 1

You'd think home shouldn't have a root parent, but it does. I think both were intended, but let's see what @ryan says.
