I'm trying to install a redistore back end for my Gorilla sessions but I keep getting undefined errors. Here is the documentation I did run go get on the packages but the package import error says that it is imported but not used.

error:

undefined: NewRediStore

code:

package main

import (
...
"github.com/gorilla/sessions"
"gopkg.in/boj/redistore.v1"
)

func main() {

    // Fetch new store.
    store, err := NewRediStore(10, "tcp", ":6379", "", []byte("secret-key"))
    if err != nil {
        panic(err)
    }
    defer store.Close()
    ...
}

You need to qualify imported identifiers by prepending them with the package name which you imported. e.g. packagename.Identifiername.

Or use . in front of the import to redeclare the exported identifiers of the imported package in the importing file's file block, however keep in mind that this is not a recommended practice.

import (
    . "gopkg.in/boj/redistore.v1"
)
