Does Mongoose support the Mongodb `findAndModify` method?

Question

I would like to use findAndModify to atomically increment a field, using Mongoose.

However, the code below throws the error \"TypeError: Object # has no method \'fin

Answer 1

I would suggest using the direct command style shown at the bottom of http://www.mongodb.org/display/DOCS/findAndModify+Command. I'm not familiar enough with mongoose to know the method for running a command, but all drivers provide some way to do it. If mongoose doesn't, you can do it directly using the style described at the top of http://www.mongodb.org/display/DOCS/Commands.

That said, you should make sure that you really need findAndModify and that update won't do what you need it to do. To see what update is capable of take a look at http://www.mongodb.org/display/DOCS/Updating.
