Emptying a database?

[David Todd]

I'm using a particular database just for testing purposes, and I'd
like to empty it before running the test suite. Is there a built in
command to either empty or drop it?

[Ben Nichols]

I have the same question. Anyone?

[Siegfried Ehret]

Dropping collections is db.<collection_name>.drop();
db.drop() doesn't work ?

[Ben Nichols]

The way I got it to work is <collection_name>.collection.drop();

In your example where is the "db" coming from?

[songhe yang]

Drop the collection:

model.collection.drop();

e.g:

var mongoose = require('mongoose')
, Schema = mongoose.Schema
, Collection = mongoose.Collection;

mongoose.connect('mongodb://localhost/test');

var TestSchema = new Schema({
user_id : {type : Number, index : true}
,username : {type : String}
});

var model_name = coll_name = 'taobao';
mongoose.model(model_name, TestSchema, coll_name);

var TAOBAO = mongoose.model(model_name, coll_name);
var taobao = new TAOBAO();
taobao.collection.drop();

Hope this will help you.

When my unit tests finish (including on uncaughtException) I just drop the entire database like this:

mongoose.connection.db.executeDbCommand( {dropDatabase:1}, function(err, result) {

    console.log(err);

    console.log(result);
    process.exit(0);
});

Also, I found the following MongoDB docs page to be really helpful--it has several examples of how commands are "JSON formatted" for something like Mongoose's executeDbCommand() function, vs. the normal examples of running the commands in the Mongo console: http://www.mongodb.org/display/DOCS/List+of+Database+Commands
