Shinydashboard administrator button

[Raymond-KT]

Hello, I appreciate the awesome shinymanager package!!

I use shinydashboard and shinymanager for my web site.

There is no problem when I use No DB shinymanager, But when I use SQL DB with shinymanager, I can't find log out/admin button.

So I can't log in to administrator mode.

Is it impossible to use admin mode on shinydashboard dashboard body?

Or Is there another way to log in to administrator mode?

Thank you!!!

Hello,

Be sure to set enable_admin = TRUE in secure_app().

Thank you for your kindness, But, I use custom auth_ui for my app instead use of secure_app().

In this case, where should I put 'enable_admin = TRUE'?

[pvictor]

Admin mode is only available using secure_app / secure_server logic (secure_app use auth_ui, and you can pass arguments from secure_app to auth_ui)

Oh!!! It's you! pvictor!! you are my hero!! I've been helped before! auth_ui Issue

Then, there is no way to use Admin mode in my situation, right? In the previous question, if I want to use a customized UI(auth_ui), secure_app should not be used.

` library(shiny) library(shinymanager) library(shinydashboard)

credentials <- data.frame( user = c("fanny", "victor"), password = c(scrypt::hashPassword("azerty"), scrypt::hashPassword("12345")), is_hashed_password = TRUE, comment = c("alsace", "auvergne"), stringsAsFactors = FALSE )

ui <- dashboardPage( dashboardHeader(), dashboardSidebar(), dashboardBody(

auth_ui(
  id = "auth",
  # add image on top ?
  tags_top = 
    tags$div(
      tags$h4("Demo", style = "align:center"),
      tags$img(
        src = "https://www.r-project.org/logo/Rlogo.png", width = 100
      )
    ),
  # add information on bottom ?
  tags_bottom = tags$div(
    tags$p(
      "For any question, please  contact ",
      tags$a(
        href = "mailto:someone@example.com?Subject=Shiny%20aManager",
        target="_top", "administrator"
      )
    )
  )
),

tags$div("Normal body content")

) )

server <- function(input, output) {

auth <- callModule( module = auth_server, id = "auth", check_credentials = check_credentials(credentials) )

}

shinyApp(ui, server) `

Yes you can use tags_top and tags_bottom with secure_app. With your shinydashboard example, it'll gives something like:

library(shiny)
library(shinydashboard)
library(shinymanager)

# Credentials as data.frame
credentials <- data.frame(
  user = c("shiny", "shinymanager"), # mandatory
  password = c("azerty", "12345"), # mandatory
  stringsAsFactors = FALSE
)

# Change labels
set_labels(
  language = "en",
  "Please authenticate" = "Bitte authentifizieren",
  "Username:" = "Benutzername:",
  "Password:" = "Passwort:",
  "Login" = "Anmeldung"
)

# Classic shinydashboard
ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(),
  title = "Dashboard example"
)

# Wrap your UI with secure_app
ui <- secure_app(
  ui = ui,
  tags_top = 
    tags$div(
      tags$h4("Demo", style = "align:center"),
      tags$img(
        src = "https://www.r-project.org/logo/Rlogo.png", width = 100
      )
    ),
  # add information on bottom ?
  tags_bottom = tags$div(
    tags$p(
      "For any question, please  contact ",
      tags$a(
        href = "mailto:someone@example.com?Subject=Shiny%20aManager",
        target="_top", "administrator"
      )
    )
  )
)

# Server
server <- function(input, output, session) {

  # With creadentials data.frame (for the example)
  res_auth <- secure_server(
    check_credentials = check_credentials(credentials)
  )
  # If you have a SQLite database, you can use:
  # res_auth <- secure_server(
  #   check_credentials = check_credentials(
  #     "path/to/database.sqlite",
  #     passphrase = "mypassphrase"
  #   )
  # )

  # your classic server logic

}

shinyApp(ui, server)

And to enable admin mode, replace credentials with an SQLite database created with create_db() and set enable_admin = TRUE in secure_app().
