[英]Can I include multiple UI elements in a single shinydashboard module?
In shinydashboard there is the amazing convenience of putting widget s into the menuItem(menuSubItems())
portion of the dashboardSidebar()
.在shinydashboard有推杆的惊人方便插件S插入
menuItem(menuSubItems())
的部分dashboardSidebar()
But I want the several elements of my UI and Server coded into modules so I can adhere to the golem framework... and I'm not seeing a clear way to do this without creating multiple UI functions for a single module.但是我希望我的 UI 和服务器的几个元素编码到模块中,这样我就可以坚持golem框架......而且我没有看到一种明确的方法来做到这一点,而无需为单个模块创建多个 UI 功能。 I've seen the
shinydashboard
golem
example on github
and it's too simple of an example that doesn't help.我见过的
shinydashboard
golem
上例github
,它太简单没有帮助的例子。
For example, Is there a way I can do this?例如,有没有办法做到这一点?
In a module format:在模块格式中:
library(shiny)
library(shinydashboard)
### The Sidebar Menu with a Widget Subitem
mod_myAppSidebar_ui<-function(id) {
ns <- NS(id)
tagList(menuItem("Attributes", tabName="ourdata",
textInput("textSearch","SQL Search String", value = "")))
}
### The Dashboard Body output
mod_myAppBody_ui<-function(id) {
ns <- NS(id)
tagList(box(shiny::dataTableOutput(outputId = "OutputData")))
}
mod_myApp_server<-function(input, output, session) {
ns <- session$ns
output$OutputData<-shiny::renderDataTable({
somedata=data.frame(Rows=letters,Indexes=1:length(letters))
somedata[grepl(tolower(input$textSearch),somedata$Rows),]
})
}
### DashboardPage requires separate arguments for the UI elements
ui <- dashboardPage(header = dashboardHeader(title = "Rosetta"),
sidebar = dashboardSidebar(mod_myAppSidebar_ui("MySearch")),
body = dashboardBody(mod_myAppBody_ui("MySearch")))
server <- function(input, output, session) {
callModule(mod_myApp_server, "MySearch")
}
shinyApp(ui,server)
Is there any way to make this kind of thing work?有没有办法让这种事情起作用? The widget isn't showing up, likely because I don't think the modular framework allows for me to make two different UI elements for one piece of functionality.
小部件没有出现,可能是因为我认为模块化框架不允许我为一项功能制作两个不同的 UI 元素。
Alright, so I got this working... surprisingly didn't take too much.好的,所以我开始工作了......令人惊讶的是并没有花太多时间。 I don't know if the complexity of my app will break this, but for anyone who was hoping to do this, maybe this is helpful:
我不知道我的应用程序的复杂性是否会破坏这一点,但对于任何希望这样做的人来说,这可能会有所帮助:
library(shiny)
library(shinydashboard)
library(DT)
mod_myAppSidebar_ui<-function(id) {
ns <- NS(id)
tagList(menuItem("Attributes", tabName="ourdata",
textInput(ns("textSearch"),"SQL Search String", value = ""),
actionButton(ns("go"),label = "Search")))
}
mod_myAppBody_ui<-function(id) {
ns <- NS(id)
tagList(fluidRow(title = "Data Selected",
box(DT::dataTableOutput(outputId = ns("OutputData")))))
}
mod_myApp_server<-function(input, output, session, r) {
ns <- session$ns
observeEvent( input$go , {
r$textSearch<-input$textSearch
print(r$textSearch)
somedata=data.frame(Rows=letters,Indexes=1:length(letters))
r$chooseData<-somedata[grepl(tolower(input$textSearch),somedata$Rows),]
})
output$OutputData<-DT::renderDataTable(r$chooseData)
}
ui <- dashboardPage(header = dashboardHeader(title = "Rosetta"),
sidebar = dashboardSidebar(mod_myAppSidebar_ui("MySearch")),
body = dashboardBody(mod_myAppBody_ui("MySearch")))
server <- function(input, output, session) {
r<-reactiveValues()
callModule(mod_myApp_server, "MySearch", r)
}
shinyApp(ui,server)
