Laravel-mongodb: Truncate should only delete the documents not drop the collection

[Idnan]

Using truncate() on model removes all the documents and indexes where as it should only delete the documents.

Here's what i used

ModelName::truncate();

[ysb]

Actually there is no truncate method for MongoDB. There are two options, drop() or remove({}). First drops all documents and indexes but it is fast, the second one removes all documents in collection in a loop, it is slow, it doesn't free up the spaces used for documents and indexes.

Eloquent method truncate() is referring to drop() method on official mongodb/mongodb package.

If you want to just remove documents, i think something like ModelName::delete(); will work.

@ysb yes but the library has a method truncate which should logically truncate the data than dropping the collection. Also here's the commit that fixed it, but I don't know why they reverted the change.

I believe that Collection::truncate() should use remove({}) for greater clarity and compatibility with Laravel. The speed of execution in this case is not so important.
