Shift

The Shift method can be chained to a query to remove the first element from an array field in the documents that match the query.

Usage

result := WitcherModel.Where("name", "Vesemir").Shift("weapons").Exec().(*mongo.UpdateResult)

In the example above, we are removing the first element from the weapons array of the witcher named Vesemir. If the array is empty, no changes will be made.
