Edit: This post actually helped me improve the deletion by having it be buttons and include a prompt to ensure users want to delete the object). Still trying to figure out how to add a row as well as edit an existing row within the page.
I am trying to build a dashboard to allow staff to view/modify the contents of a CSV file. In this case, it’s printer files that define the printers available to a virtual desktop.
The CSV is one or more lines containing the hostname, printer IP, printer name, and printer driver to use.
A sanitized example:
Hostname,PrinterIP,PrinterName,PrinterDriver
PC001,10.0.0.63,Printer01,HP LaserJet 4
PC001,10.0.0.83,Printer02,Xerox VersaLink C400 PCL6
PC001,10.0.0.58,Printer03,Xerox Phaser 6600DN PCL6
Of note, the first printer in the file becomes the default in Windows for the user. So I have the following main goals:
- Add a new row
- Allow selecting a default (or re-ordering the list dynamically to place a new item in the first row)
- Change a value within a row (e.g. change the “Printer Name” or “Printer IP” on a row)
- Delete an existing row
I’ve had some success with the updating the default printer or deleting a row using the below code, however, users have to reclick on the “Submit” button to modify/update the table. More importantly, I’m stumped how to set the table to allow for adding a row or to modify an existing value in one of the existing rows. I am not particularly proud of the below code at all, so if there is a better approach, I am completely open.
