FCKeditor. This is the only way to retrieve files that the
FCKeditor has renamed after the upload.
Eg: 'prefix/image.jpg' was uploaded but did already
exist. FCKeditor silently renamed it to 'prefix/image(0001).jpg':
>>> retrieve_most_recent_attached_file('prefix/image.jpg')
'prefix/image(0001).jpg'
"""
(base_path, filename) = os.path.split(file_path)
base_name = os.path.splitext(filename)[0]
file_ext = os.path.splitext(filename)[1][1:]
most_recent_filename = filename
for i in range(1, 10000): # FCKeditor renames up to 9999. After it overwrites.
possible_filename = "%s(%04d).%s" % \
(base_name, i, file_ext)
if os.path.exists(base_path + os.sep + possible_filename):
most_recent_filename = possible_filename
else:
break
return os.path.join(base_path, most_recent_filename)
