I have a collection that I cycle through and attempt to add a new property suffix
with an empty values.
$results = Models\EloTable
::hydrate((array) $query)
->load(
'extraction',
'reference'
);
foreach ($results as $result) {
foreach ($result->data->authors as $author) {
$author->suffix = '';
}
}
Currently, every $author
has two properties,
{
lastName: "Lastname",
firstName: "Firstname"
}
If I dd($author);
after the first iteration, I will get
{
lastName: "Lastname",
firstName: "Firstname",
suffix: ""
}
But if I dd($results);
after the two foreach
loops, it will not persist the addition of the empty suffix
properties.
How can I change the collection to persist the suffix
property?
You can append an attribute to a model like this:
Model:
protected $appends = ['suffix'];
public function getSuffixAttribute()
{
return null;
}

If you don't load data
and data.authors
in your original $results
then calling $results->data->authors
or something similar later down the line will re-query the database, pulling a fresh copy of authors
that hasn't been modified.
Just change $results
to :
$results = Models\EloTable
::hydrate((array) $query)
->load(
'extraction',
'reference',
'data',
'data.authors',
);
