Pop

The Pop method can be chained to a query to remove the specified number of elements from the end of an array field in the documents that match the query.

Usage

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

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

Usage with a second argument

result := WitcherModel.Where("name", "Vesemir").Pop("weapons", 2).Exec().(*mongo.UpdateResult)

In the example above, we are removing the last 2 elements from the weapons array of the witcher named Vesemir. If the array has fewer than 2 elements, all elements will be removed. If the array is empty, no changes will be made.
