How To Set A Standalone Attachment Content Type

[Brad Rhoads <bd...@gmail.com>]

http://stackoverflow.com/questions/13281021/how-to-set-a-standalone-attachment-content-type

I've been able to create a standalone attachment, but the content_type ends
up as multipart/form-data. What I am I doing wrong? The code is followed by
the response from the post and then the request; you can see in the request
that the content type is correct in the Request Payload.

Code:

 function uploadFile() {
    var fd = new FormData();
    var file = document.getElementById('fileToUpload').files[0];
    fd.append("fileToUpload", document.getElementById('fileToUpload').files[0]);
    var xhr = new XMLHttpRequest();
    xhr.upload.addEventListener("progress", uploadProgress, false);
    xhr.addEventListener("load", uploadComplete, false);
    xhr.addEventListener("error", uploadFailed, false);
    xhr.addEventListener("abort", uploadCanceled, false);
    xhr.open("PUT",
"http://usr:pswd@localhost:5984/db_test/testdoc7/"+ file.name
+"?rev=1-967a00dff5e02add41819138abb3284d");

    xhr.send(fd);
  }

Response:

{
   "_id": "testdoc7",
   "_rev": "2-2841dcd640adb94de525e486be34052e",
   "_attachments": {
       "P9025287.JPG": {
           "content_type": "multipart/form-data;
boundary=----WebKitFormBoundary9QNXLDTeW13Gc1ip",
           "revpos": 2,
           "digest": "md5-VcoscthaPUYoWHBmCBaAnA==",
           "length": 3083669,
           "stub": true
       }
   }
}

As shown in the HTTP log, the Content-Type header of the PUT is “multipart/form-data”, so that’s what CouchDB stores as the MIME type of the attachment. If you want it to remember a different type, you should send that as the value of the Content-Type header.
