Re: MongoDB removing document

The actual ID you are trying to delete has the VALUE 'something_unique' , and is of the TYPE/CLASS 'MongoDB::OID'.

So - without knowing the MongoDB API, your error is passing in the TYPE, rather than the VALUE.

I'd suggest:

$doc->delete_one( {'_id'=>$doc->{_id} } );
  # If that fails, try:
$doc->delete_one( {'_id'=>$doc->{_id}{value} } );

There are potentially other issues, but this should help step you past the current one.

good luck.

The best defense against logic is ignorance.

Thank you for your reply Unfortunately I keep getting the message: `Can't call method "delete_one" on unblessed reference at line...` [download] I'll investigate further.	[reply] [d/l]

I know absolutely nothing about MongoDB, but I can tell you that you're trying to call a method on something that doesn't have any (a plain hash reference). In the MongoDB documentation's SYNOPSYS, it shows that to delete a document, you call the method against the collection (`$coll`) object like this: `$coll->delete_one({ name => 'value' });` For completeness, here's the expanded documentation specifically for the delete_one() method. When in doubt, RTFM ;)	[reply] [d/l] [select]

Thanks, after studying the documents (that are really well done!) I indeed do have a problem executing the proper commands while iterating the MongoDB::Cursor. There are not too many examples of that.	[reply]
