Find One And Update

The FindOneAndUpdate method is used to find a single document in the database and update it.

Usage

witcher := WitcherModel.FindOneAndUpdate(primitive.M{"name": "Vesemir"}, primitive.M{"age": 200}).ExecPtr()

The example above finds a single witcher with the name "Vesemir" and updates their age to 200 and returns the document as it was before the update.

Usage with Options

You can pass options to the FindOneAndUpdate method to specify how the update operation should be performed.

opts := options.FindOneAndUpdateOptions{}
opts.SetReturnDocument(options.After)
witcher := WitcherModel.FindOneAndUpdate(primitive.M{"name": "Vesemir"}, primitive.M{"age": 200}, &opts).ExecPtr()

In the example above, we are passing options to the FindOneAndUpdate method to return the document after the update operation has been performed.
