FileUploadHandler.receive_data_chunk(raw_data, start) [source]
Receives a “chunk” of data from the file upload.
raw_data is a byte string containing the uploaded data.
start is the position in the file where this raw_data chunk begins.
The data you return will get fed into the subsequent upload handlers’ receive_data_chunk methods. In this way, one handler can be a “filter” for other handlers.
Return None from receive_data_chunk to short-circuit remaining upload handlers from getting this chunk. This is useful if you’re storing the uploaded data yourself and don’t want future handlers to store a copy of the data.
If you raise a StopUpload or a SkipFile exception, the upload will abort or the file will be completely skipped.
