如何将InMemoryUploadedFile对象复制到磁盘
我试图捕获与表单一起发送的文件,并在对其进行保存之前对其执行一些操作。因此,我需要在temp目录中创建此文件的副本,但是我不知道如何到达它。Shutil的功能无法复制此文件,因为没有路径。那么,是否有其他方法可以执行此操作?
我的代码:
image = form.cleaned_data['image'] temp = os.path.join(settings.PROJECT_PATH, 'tmp')
sourceFile = image.name # without .name here it wasn't working either
import shutil
shutil.copy(sourceFile, temp)
引起:
Exception Type: IOError at /Exception Value: (2, 'No such file or directory')
和调试:
# (..)\views.py in function 67. sourceFile = image.name
68. import shutil
69. shutil.copy2(sourceFile, temp) ...
# (..)\Python26\lib\shutil.py in copy2
92. """Copy data and all stat info ("cp -p src dst").
93.
94. The destination may be a directory.
95.
96. """
97. if os.path.isdir(dst):
98. dst = os.path.join(dst, os.path.basename(src))
99. copyfile(src, dst) ...
100. copystat(src, dst)
101.
▼ Local vars
Variable Value
dst
u'(..)\\tmp\\myfile.JPG'
src
u'myfile.JPG'
# (..)\Python26\lib\shutil.py in copyfile
45. """Copy data from src to dst"""
46. if _samefile(src, dst):
47. raise Error, "`%s` and `%s` are the same file" % (src, dst)
48.
49. fsrc = None
50. fdst = None
51. try:
52. fsrc = open(src, 'rb') ...
53. fdst = open(dst, 'wb')
54. copyfileobj(fsrc, fdst)
55. finally:
56. if fdst:
57. fdst.close()
58. if fsrc:
▼ Local vars
Variable Value
dst
u'(..)\\tmp\\myfile.JPG'
fdst
None
fsrc
None
src
u'myfile.JPG'
回答:
这是类似的问题,可能会有所帮助。
import osfrom django.core.files.storage import default_storage
from django.core.files.base import ContentFile
from django.conf import settings
data = request.FILES['image'] # or self.files['image'] in your form
path = default_storage.save('tmp/somename.mp3', ContentFile(data.read()))
tmp_file = os.path.join(settings.MEDIA_ROOT, path)
