我正在尝试捕获与表单一起发送的文件并在保存之前对其执行一些操作。所以我需要在临时目录中创建这个文件的副本,但我不知道如何访问它。Shutil 的函数无法复制此文件,因为它没有路径。那么有没有办法以其他方式进行此操作?
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)
这引发了:
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.

46. if _samefile(src, dst):
47. raise Error, "`%s` and `%s` are the same file" % (src, dst)

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:
