Gin: Is it possible to save currentUser to varible

[olegsobchuk]

I check for currentUser in next way

users := router.Group("/users")
    {
        users.Use(checkCurrentUser())
        users.GET("/show", controllers.ShowUser)
    }

and it check it correctly, but very often this currentUser needed inside handler, for example to get all his associations (doesn't matter).

// ShowUser shows information about user
func ShowUser(c *gin.Context) {
    user := gerCurrentUser(c) // I do additional request to the DB
    c.HTML(200, "showUser", gin.H{
        "currentUser": user,
    })
}

And I have to do additional request to the DB, to get this record.

Is It possible to save currentUser somewhere and use it inside the handler?

You can use redis

you can use session, jwt, redis..etc...

So I found how I can do it
Function Set() helped me
I can use it in me checkCurrentUser()

func checkCurrentUser() gin.HandlerFunc {
    return func(c *gin.Context) {
        session := sessions.Default(c)
        userID := session.Get("userID")
        user := new(models.User)
        configs.DB.First(&user, userID)
        if configs.DB.NewRecord(user) {
            c.Redirect(http.StatusPermanentRedirect, "/login")
        } else {
            c.Set("currentUser", user)
            c.Next()
        }
    }
}

and now I can get this instance with

currentUser := c.MustGet("currentUser")

Thx, issue may be closed!
