[web2py] Check it out: PURE AJAX file uploads :D

[select]

in your client side js code use the js file api (this is for one file, but 
multi file upload can be done too)

$('#datafile-uploadfield').change(function() {
    var upload_element = $(this)[0];
    var file = upload_element.files[0];
    if (file) {
      var reader = new FileReader();
      reader.readAsDataURL(file); //, "UTF-8");//TODO what encoding should 
be parsed???
      reader.onload = (function(theFile) {
        return function(evt) {
          $.ajax({
            url: '{{=URL("datafile_create")}}',
            data: {
              data: evt.target.result,
              name: theFile.name
            },
            type: 'POST',
            dataType: 'json',
            success: function(data) {
              addDatafile(data);
            }
          });
        };
      })(file);
      reader.onerror = function(evt) {
        alert(":( oh noo, we could not read your file");
      };
      //++counter;
    }
  });

in you controller
def datafile_create():
    splitcontents = request.vars.data.split(',')
    import base64
    file_content = base64.b64decode(splitcontents[1])
    # create file like object
    import StringIO
    filelike_obj = StringIO.StringIO(file_content)
    db_store = db.datafiles.file.store(filelike_obj, request.vars.name)
    record_id = db.datafiles.insert(file=db_store)


in you db.py
db.define_table('datafiles',
 Field('file', 'upload', requires=IS_NOT_EMPTY()),
 )

== PURE AWESOMENESS
