Retrieve custom fields from child of a child model in Laravel eloquent - laravel

Question

I'm trying to retrieve custom fields from a model using the with() statement in Laravel. When I just get all fields the child object comes ok, but when I try to retrieve just some fields of this child abject it returns to me the following error:
Integrity constraint violation: 1052 Column 'id' in field list is ambiguous
below I'll show how I'm doing these queries.
When I execute the following query it works:
$cfps = CallForPaper::select('id', 'speech_id')->with([
'speech:id,title,description',
'speech.speakers'
])->get();
But when I execute the code below it returns the error which I have mentioned above.
$cfps = CallForPaper::select('id', 'speech_id')->with([
'speech:id,title,description',
'speech.speakers:id,name,email'
])->get();
Note: than only modification in this code is the line: 'speech.speakers:id,name,email'
in my model Speech, the speakers relationship is the following:
public function speakers()
{
return $this->belongsToMany(Speaker::class, 'speech_speaker');
}

Answer 1

You will need to define the table_name for the id's your are selecting:
$cfps = CallForPaper::select('id', 'speech_id')->with([
'speech:TABLE_NAME.id,title,description',
'speech.speakers:TABLE_NAME.id,name,email'
])->get();
you can also do the following, ie. rename the id:
$cfps = CallForPaper::select('id', 'speech_id')->with([
'speech:TABLE_NAME.id as speechID,title,description',
'speech.speakers:TABLE_NAME.id as speakerID,name,email'
])->get();
