You need to update the render() function in main.go in order to pass the variable to the templates.

func render(c *gin.Context, data gin.H, templateName string) {
    loggedInInterface, _ := c.Get("is_logged_in")
    data["is_logged_in"] = loggedInInterface.(bool)

    switch c.Request.Header.Get("Accept") {
    case "application/json":
	c.JSON(http.StatusOK, data["payload"])
    case "application/xml":
	c.XML(http.StatusOK, data["payload"])
    default:
	c.HTML(http.StatusOK, templateName, data)
    }
}
