30811	Django throws 'UnicodeEncodeError' when using Cyrillic symbols to override field upload_to.	Kirill	Kirill	"So, I have a ''Book'' model, that contains some fields. But most important are:
**'title' as 'CharField'**
**'pdf', 'epub', 'fb2' as 'FileField'**
**'image' as 'ImageField'**
we will return to they in just a second...
My ''Book'' model also has overrided ''clean'' method. In that method I assign my ''title'' field value as ''upload_to'' value.

{{{
uploading_files = [
    self.image,
    self.pdf,
    self.fb2,
    self.epub
]
for file_ in uploading_files:
    file_.field.upload_to = self.title
}}}
Here is where bug hided. If I set ''title'' value to ""Колобок"", for example, it throws me an ''UnicodeEncodeError''. This thing happends only when i first create model.
If I firstly will set ''title'' value as ""Kolobok"", and later rename it to ""Колобок"", I have no error.

----

I already some kind of ""fixed"" this.
Endpoint of thrown exception was **...\django\db\models\fields\files.py**. After fork from your Github, I followed this path, and find function that throws that error, that function was ''generate_filename'' in ''FileField'' class, line 305. After I added small correct...

{{{
try:
    dirname = datetime.datetime.now().strftime(self.upload_to)
except UnicodeEncodeError:
    dirname = self.upload_to
}}}

... all works fine now, and I can use Cyrillic symbols as my ''title'' and folder name in ''upload_to'' attribute.
