New description:
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.
