How to remove all items from collection stored in mongodb using GO lang?
In mongo console I can use:
db.mycollection.remove({})
where empty brackets {} mean all document pattern.
In GO lang (I use "gopkg.in/mgo.v2" and "gopkg.in/mgo.v2/bson") there are methods:
sess.DB("mydb").C("mycollection").Remove(...)
or
sess.DB("mydb").C("mycollection").RemoveAll(...)
but both of them needs parameter that implements selector. For example selector can be a bson map
bson.M{"id": id}
but I want to remove all elements, not a particular one.
