"Refetch" is quite ambiguous, somebody might expect that it will overwrite existing files. Can we call it "Fetch missing files" (or "Refetch missing files")?

It would also be nice to have the button disabled if no files are actually missing.

Sure, the button can be renamed to "Refetch missing files".

The problem with disabling the button is that the Exchange has no API for listing all the files of an assignment. Or well... there is ExchangeList.list_files(), but in the default exchange, it is implemented in a weird way, where it does not really list any files. Instead, it returns a list of assignments. So it sure can be done by modifying the exchange a bit, but people can already rely on the way it works now so then it would break their stuff. Someone can even have their own exchange implementation, and since the output of list_files() is not unified, I think, it will not work for everyone.

Do you have any better idea regarding this?

Oh, so the API would probably have to be extended with a new function... But it can be done later, this is still a big improvement!

refetchButton.onclick = async function(){
refetchButton.innerText = 'Refetching...';
refetchButton.setAttribute('disabled', 'disabled');
const dataToSend = { course_id: that.data['course_id'], assignment_id: that.data['assignment_id']};
try {
const reply = await requestAPI<any>('assignments/fetch_missing', {
body: JSON.stringify(dataToSend),
method: 'POST'
});

that.on_refresh(reply);

} catch (reason) {
remove_children(container);
container.innerText = 'Error refetching assignment.';
console.error(
`Error on POST /assignment_list/fetch_missing ${dataToSend}.\n${reason}`
);
}
}

button.innerText = "Submit";
button.onclick = async function(){
button.innerText = 'submitting...';
