Hi,
Not sure if this is a bug, a feature or documentation request.
I am using XMLHttpRequest to PUT an attachment to an existing
document. This works, see my client side JavaScript below.
However I noticed sometimes someone uploads an attachment but Firefox
got the content-type wrong (done on the client side with my SUPER
HACK). To correct this, I use Futon to edit the document JSON source
and change the content_type and save the document. But my change to
the content_type field does not get saved.
I guess I can take a look at the Futon source, but thought I'd ask
here first for suggestions.

<script type="text/javascript">
$(function() {
$('#upload-form').submit(function(){
// Have to ask for the doc JSON in order to get the rev
// since we can't PUT or DELETE attachments without the current rev.
// Not having the current rev, results in 409 conflict.
$.getJSON("<%= docURL %>", function(doc){
// Firefox 3 only...
var file = $('#upload-form #file')[0].files.item(0);
var xhr = new XMLHttpRequest();
xhr.open("PUT", "<%= docURL %>/" + file.fileName + "?rev=" +
doc._rev, true);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
if (xhr.status == 201) {
// OK!
} else {
}
}
};
xhr.setRequestHeader('Content-Length', file.fileSize);
// Mime-type SUPER HACK
xhr.setRequestHeader("Content-Type",
file.getAsDataURL().match(/data:([^;]*);/)[1]);
xhr.sendAsBinary(file.getAsBinary());
});
return false;
});
});
</script>
