[英]Persistent data in reactive editable table in Shiny app using DT
[英]R shiny, Editable DT table Module with reactive data as input
我正在尝试创建一个可编辑的 shiny DT 表模块。 当我传入虹膜数据时效果很好。 但是,当我尝试传递反应值时,模块不起作用。 以前有没有人有过类似的经历? 你能分享你的想法吗?
library(shiny)
library(DT)
editableUI<-function(id){
ns <- NS(id)
DT::dataTableOutput(ns("mod_table"))
}
editableUIServer<-function(id,data,disable_col,change){
moduleServer(id,
function(input,output,session){
print('hi')
v<-reactiveValues(data = data)
print('here we got v')
print(v$data)
output$mod_table <- renderDT(v$data,
editable = list(target = 'cell',
disable = list(columns=c(disable_col))))
proxy = dataTableProxy('mod_table')
observeEvent(input$mod_table_cell_edit, {
info = input$mod_table_cell_edit
v$data <<- editData(v$data, info)
replaceData(proxy, v$data, resetPaging = FALSE)
})
observeEvent(change(),{
v$data<<-data
})
return(v)
}
)}
# Define UI for application that draws a histogram
ui <- fluidPage(
fluidPage(
fluidRow(pickerInput('spec',label = 'Species',choices = unique(as.character(iris$Species)),selected = "versicolor")
),
fluidRow(editableUI("test")))
)
# Define server logic required to draw a histogram
server <- function(input, output) {
data<-reactive({
iris %>% filter(Species %in% c(input$spec))
})
observe({print(data())})
v<-reactive({editableUIServer("test",data(),c(1), change_ppg = reactive(input$spec))})
}
# Run the application
shinyApp(ui = ui, server = server)
我改变了几行,现在它可以工作了。 虽然不知道为什么它首先是错误的
library(shiny)
library(DT)
editableUI<-function(id){
ns <- NS(id)
DT::dataTableOutput(ns("mod_table"))
}
editableUIServer<-function(id,data,disable_col){
moduleServer(id,
function(input,output,session){
print('hi')
v<-reactiveValues(data = data)
print('here we got v')
output$mod_table <- renderDT(v$data,
editable = list(target = 'cell',
disable = list(columns=c(disable_col))))
proxy = dataTableProxy('mod_table')
observeEvent(input$mod_table_cell_edit, {
info = input$mod_table_cell_edit
v$data <<- editData(v$data, info)
replaceData(proxy, v$data, resetPaging = FALSE)
})
return(v)
}
)}
# Define UI for application that draws a histogram
ui <- fluidPage(
fluidPage(
fluidRow(pickerInput('spec',label = 'Species',choices = unique(as.character(iris$Species)),selected = "versicolor")
),
fluidRow(editableUI("test")))
)
# Define server logic required to draw a histogram
server <- function(input, output) {
data<-reactive({
iris %>% filter(Species %in% c(input$spec))
})
# v<-reactive({editableUIServer("test",data =iris,c(1), change_ppg = reactive(input$spec))})
v<- reactive(editableUIServer("test",data(),c(1)))
observe(print(v()$data))
}
# Run the application
shinyApp(ui = ui, server = server)
