OctoberCMS get id of component being saved - laravel

Question

I am trying to update a table with the path of the uploaded file so that it is easy to email a download link but I cannot seem to get the id.
My component looks like this:
public function onAddJob() {
$manual = new Job();
$manual->company = Input::get('company_name');
$manual->ordered_by = Input::get('client_name');
$manual->ordered_by_email = Input::get('client_email');
$manual->emergency_no = Input::get('emergency_no');
$manual->instructions = Input::get('instructions');
$manual->project_name = Input::get('project_name');
$manual->fileupload = Input::file('fileuploader');
$manual->save();
$this->id = $this->property('id');
Db::table('manual_jobs')->where('id', $this->id)->update(['path' => $manual->fileupload->getPath()]);
Everything saves fine but path is not updated as I am not getting the id correctly, can anyone help show me where I am noobing?

Answer 1

The id component is defined by the variable $primaryKey on the model
default the primary key is 'id' corresponding to a database table field named id
You can overwrite the default keyname by setting $primaryKey to another key
class Foo extends Model {
$primaryKey = 'foo_id';
}
Why i'm explaining this is because you don't need to know the name of the field.
What you can do is:
$foo = new Foo();
$foo->bar = 'baz';
$foo->save();
echo $foo->getKey();
echo $foo->getAttribute($foo->getKeyName());
echo $foo->{$foo->primaryKey}
They will all print out the newly created primary key on the object.
getkey() returns the value of the primary key.
getKeyName() returns the name of the primary key field defined in the model

Answer 2

The solution was a lot simpler than I thought.
What I was looking for was this:
$manual->id
So the update query looks like this:
Db::table('manual_jobs')->where('id', $manual->id)->update(['path' => $manual->fileupload->getPath()]);

Answer 3

Its because when you call ajax request it will not call pageCycle.
as a result your code in page will not executed.
your code on page may be look like this one
{% component 'yourComponent' id=someID %}
but this code is not executed during ajax call
to execute page code during ajax call you need to explicitly call $this->controller->pageCycle()
so new code will look like
public function onAddJob() {
// we are calling page code explicitly
$this->controller->pageCycle();
$manual = new Job();
$manual->company = Input::get('company_name');
$manual->ordered_by = Input::get('client_name');
... other code
}
