Python Document.document_type方法代码示例

# 需要导入模块: from models import Document [as 别名]
# 或者: from models.Document import document_type [as 别名]
def upload(request):
    # Handle Video upload

    # A lot going on here especially shell commands
    # 3 files get uploaded with various meta info fields
    # Using FFMPEG 2 videos are converted to mp4 regardless of 
    # what they are when uploaded first. Then they get renamed, 
    # saved and the original ones are deleted
    # A poster image for the first frame is also uploaded and 
    # resized using image Magick.
    # Function execute_shell is used a lot sending lots of commands through
    # pythons subprocess synchronously
    # May redo this so it is done asynchronously but afraid people will think
    # Nothing happened and not come back.
