QUESTION
Based on the very useful reproductive example found here, I have added a dropdown list to every columns of my DT table.
However I'm looking for a way to populate those dropdown lists with values from another dataframe that shares the same column names than the one use in the DT table.
I tried to subset the second dataframe (here "iris2") with the input$dtable_columns_selected but I think I'm missing something here...
My attempt:

QUESTION
I based the code below on Stephane Laurent's solution to the following question on Stack Overflow:
Edit datatable in Shiny with dropdown selection for factor variables
I added in code to use editData to update the table and to be able to save/export the updates.
The following works with DT v0.18 but with DT v0.19 I found the id_cell_edit seems to not be triggering. I am unsure if it has to do with the callback or possibly jquery.contextMenu given DT v0.19 upgraded to jquery 3.0. Would appreciate any insight people may have on how to work through this.
Here is a description of the behavior I observe when using v0.18. When I select the usage column and update the value for the first row from the default “sel” to “id” the value changes in the DT table. I also see it updates the view of the tibble and thus the data in the download csv file is also updated. If I progress to the Next page to see the 11th item, and then return back to the first page, I can see the record I updated still says “id”.
Here is a description of the behavior I observe when using v0.19. When I select the usage column and update the value for the first row from the default “sel” to “id” the value changes in the DT table. It does not update the view of the tibble and thus the data in the download csv file does not get updated. If I progress to the Next page to see the 11th item, and then return back to the first page, the update I had made gets cleared.
Note that I also ran reactive graphs using reactlog. I followed the same steps to update the usage column of the first row to "id". The first difference I note is that reactiveValues###$dt at Step 5 gives me a list of 7 when I use version v0.18 and a list of 8 when I use version v0.19. At Step 16, for v0.18 input$dt_cell_edit invalidates, then Data invalidates and output$table invalidates. At Step 16 when using v0.19, however, output$dt invalidates then output$table invalidates. In other words, when using v0.19 input$dt_cell_edit and Data are not invalidating.

QUESTION
I have a Shiny app with a DT datatable in which I can change the column names via Javascript (thanks to another Stackoverflow entry). I would like to store the changed column names in a reactiveVal. However, this does currently not work.
Here is the current code which I use:

QUESTION
I am trying to send gmail using nodemmailer and axios in react application. But the response i get is the entire file contents. Any help is greatly appreciated. Thank you.
Here is my frontend axios post request. THis request is working fine its returing 200 status code. The problem is with the response.
...ANSWER
Answered 2020-May-31 at 06:04The issue is you have added mail.js file to public directory.
app.use('/static', express.static(path.join(__dirname, 'public')))
So what is happening is when ever you hit https://localhost/mail it is resolving any file matching in public and serving content.
Make sure you don't add it in public directory. or anyother directory which is used to add client side code.
