findOrCreate return parameter

[Andreas Lenhardt]

Hello,

what does the findOrCreate function return?

If the entry is found, it probably returns the bean, but does it return null, empty array or the id if the entry is created and stored?


[Ben Major]

It always returns the bean. Why would it return anything other than that, surely the whole point is to ensure your var is a reference to a bean?

Hi Andreas,

It does exactly what it says: If you search for a bean using certain criteria, if it do not exists, it will be created and the bean is returned.

Consider this code:

R::setup();

R::nuke();

R::store(R::dispense([

'_type' => 'person',

'name' => 'John Doe',

]));

$person = R::findOrCreate('person', ['name'=>'John Doe']);

print_r($person->export());

$person = R::findOrCreate('person', ['name'=>'Jane Doe']);

print_r($person->export());

Searching john doe it will return id=1 because already exists.

Searching jane doe it will return id=2 because it do not exists and it was created.

Of course it makes sense that a new bean is created :)
I thought, maybe the function also gives me information about whether a bean has been loaded or if a new bean was created.
This dinstinction would be very handy in my opinion.

Hi, doesn't make sense to me to use this function and an if statement to check the type of return. For this distinction I

use R

::find() first and R::dispense() if necessary. The findOrCreate is most like a shortcut if this distinction is not necessary. That is true in many cases for me at least.
