I am setting up a module, with the purpose of having two data tables in the same app, in different tabs. I would like to be able to edit and save each table separately. In my code, only the first "save" button works, and it saves both data tables. Ideally, each save button should work and save only the corresponding table.
Here is my problematic code:
library(shiny)
library(DTedit)
myModuleUI <- function(id,nam) {
ns <- shiny::NS(id)
shiny::tagList(
br(),
##### needs corrections!!
tabsetPanel(tabPanel("XXX", dteditmodUI(ns(nam)),actionButton(ns("reset"), "Reset to Saved", styleclass = "warning"), actionButton(ns("saveBtn"), label = "save"), br(),
id=ns('tabset'), type = 'tabs')
)
)
####
}
myModule <- function(input, output, session,df,nam,taby,wb) {
dfr=reactiveVal()
dfr(df)
Grocery_List_Results <- shiny::callModule(
dteditmod,
id = nam,
thedata =dfr)
# ### save part
savd = data.frame(isolate(dfr()))
observeEvent(input$saveBtn, {
print("Q")
## Add worksheets
st = paste(taby,as.character(unclass(Sys.time())),sep="_")
addWorksheet(wb, st)
writeData(x = Grocery_List_Results$thedata,
wb = wb,
sheet = st)
saveWorkbook(wb, "wb.xlsx", overwrite = T)
savd <<- Grocery_List_Results$thedata
shinyalert(title = "Saved!", type = "success")
})
observeEvent(input$reset, {
dfr(savd)
print(dfr)
shinyalert(title = "Reset to saved data!", type = "info")
})
}
########
ui <- fluidPage(
h3('Grocery List'),
myModuleUI('myModule1',nam="groc"),br(),
myModuleUI('myModule1',nam="groc2")
)
server <- function(input, output, session) {
df= data.frame(
Buy = c('Tea', 'Biscuits', 'Apples',"Tea","Apples"),
Quantity = c(7, 2, 5,9,44),
stringsAsFactors = FALSE
)
file = "AICs.xlsx"
wb <- loadWorkbook(file)
shiny::callModule(myModule, 'myModule1',nam="groc",df=df,taby="Tea",wb)
shiny::callModule(myModule, 'myModule1',nam="groc2",df=df,taby="Apples",wb)
}
shinyApp(ui = ui, server = server)

Hope for your input! Many thanks!!
