model - Django ImageField error : cannot open image file -

i put imagefield model , can upload image file. when try open file through admin page. cannot open file there error says "500 internal server error".

in file name there non-ascii letters inside. how can fix problem?

class customer(user):     profile_image = models.imagefield(upload_to='customers/photos', null=true, blank=true)     hospital = models.foreignkey('hospital', null=true, blank=true)     treatments = models.manytomanyfield('treatment', blank=true)     verified = models.booleanfield(default=false)      def get_full_name(self):         return self.email      def get_short_name(self):         return self.email   image file name = "데이비드_베컴2.jpg" 

actually model has more 1 field..

+) admin.py

class customeradmin(useradmin):     form = customerchangeform     add_form = customercreationform      # fields used in displaying user model.     # these override definitions on base useradmin     # reference specific fields on auth.user.     list_display = ('email', 'phonenumber', 'is_admin')     list_filter = ('is_admin',)     fieldsets = (         (none, {'fields': ('email', 'password', 'phonenumber', 'smscheck',                   'name', 'hospital', 'major', 'treatments', 'info', 'profile_image', 'verified', )}),         ('personal info', {'fields': ()}),         ('permissions', {'fields': ('is_active', 'is_admin',)}),     )     # add_fieldsets not standard modeladmin attribute. useradmin     # overrides get_fieldsets use attribute when creating user.     add_fieldsets = (         (none, {             'classes': ('wide',),             'fields': ('email', 'password1', 'password2', 'phonenumber', 'smscheck',                   'name', 'hospital', 'major', 'treatments', 'info', 'verified', 'is_active', 'is_admin')}         ),     )     search_fields = ('email', 'phonenumber')     ordering = ('email',)     filter_horizontal = () 

also when put file encoded english has no problem.. example, "myprofile.jpg"

how can fix problem? in advance!

finally found solution error.

just implement new custom field yourself.

import unicodedata django.db.models import imagefield  class myimagefield(imagefield):      def __init__(self, *args, **kwargs):         super(myimagefield, self).__init__(*args, **kwargs)      def clean(self, *args, **kwargs):         data = super(myimagefield, self).clean(*args, **kwargs)         data.name = unicodedata.normalize('nfkd', data.name).encode('ascii', 'ignore')         return data
