Currently ProgressBar is used to monitor upload progress of attachments.
But there's two cases where the associated DOM element may be removed:
- In the champs editor, when the list scrolls, DOM elements are removed
and added dynamically by React;
- In the user form, the user might start an upload on a repetition, and
then remove the associated row during the download.
In both those cases, we don't want the missing DOM element to trigger
an error.
We have errors in production where the job starts correctly (i.e. the
blob exists), but `blob.open` fails with a `ActiveStorage::FileNotFound`
error.
When checking later in production, the blob has been deleted.
This points to the blob (and the file) being deleted during the virus
scan job.
In that case, ignore the error (rather than retrying the job).
Currently, deselecting all values from a multiple dropdown rendered as
checkboxes doesn't have any effect when submitting the form (the
previous values are still there, instead of being deselected).
This is because unchecked checkboxes are not sent by the browser – so
the "empty selection" never gets sent.
Rails `form.check_box` usually works around this by inserting an empty
hidden checkbox element, that will be sent even if all others are
de-selected. But the documentation warns that this is not possible when
iterating over an array (rather than a model). Which is our case here.
To fix this, this commit uses `collection_check_boxes` instead. It will
insert the proper hidden checkboxes in all cases, and fix our use case.
See https://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-collection_check_boxes
This fixes an issue where clicking quickly on several "Remove row"
buttons on a repetition field results in autosave errors.
This is because the N+1 autosave request is correctly sent after the
Nth response from the server, but _before_ the row element is actually
removed from the DOM. So the N+1 request actually sends the fields for
the deleted row, which makes the server raise an error.
With this fix, the row gets properly removed when the server responds,
and before the next request is started.
