overwriting data on Model.insertMany with Mongoose
<p>I have something like this:</p>

<pre><code> Accounts.insertMany(topAccounts)
            .then(function (result) {
                console.log('Succesfully saved '+ result.length + ' documents... closing connection...')
                mongoose.connection.close(); 
            })
            .catch(function(err){
                console.log('oh shit');
                console.log(err);
            })
</code></pre>

<p>This appends the saved data to my collection. Is there any way to overwrite it instead? Is my best solution to simply delete the collection before saving the data?</p>
