ファイルをアップロードするDjangoは「デフォルト」の画像を削除します

Question

私は、従業員の画像、名前、タイトル、ソーシャルメディア情報をアップロードできるOurteam Appを持っています。オブジェクトを作成するたびに、「default.jpg」ファイルがmedia_rootから削除されます。

これは私のモデルである：

from django.db import models 
from cms.models.pluginmodel import CMSPlugin 
from django.utils.translation import ugettext_lazy as _ 
from smartfields import fields 
from smartfields.dependencies import FileDependency 
from smartfields.processors import ImageProcessor 
from django.template.defaultfilters import slugify 


class Employee(CMSPlugin): 

    # Set Name 
    name = models.CharField(_('name'), max_length=48) 

    # Define Slug 
    slug = models.SlugField(max_length=40, null = False, blank = True) 

    # Set Title 
    title = models.CharField(_('title'), max_length=48) 

    # Set Image upload path and image properties 
    image_upload_path = 'ourteam/%Y/%m/%d' 

    image = fields.ImageField(upload_to=image_upload_path, 
     blank=True, default='ourteam/default.jpg', 
     dependencies=[ 
      FileDependency(processor=ImageProcessor(
       format='JPEG', scale={'max_width': 150, 'max_height': 150})) 
     ]) 

    created = models.DateTimeField(_('created'), auto_now_add=True) 
    email = models.EmailField(_('email'), max_length=254) 

    # Social Media 
    twitter = models.CharField(_('twitter'), max_length=24, blank=True, default='https://www.twitter.com') 
    linkedin = models.CharField(_('linkedin'), max_length=24,blank=True, default='https://www.linkedin.com') 
    facebook = models.CharField(_('facebook'), max_length=24,blank=True, default='https://www.facebook.com') 

    class Meta: 
     verbose_name = _('employee') 
     verbose_name_plural = _('employee') 
     db_table = 'employee' 
     ordering = ('-created',) 
     get_latest_by = 'created' 

    def __unicode__(self): 
     return u'%s' % self.title 

    def __str__(self): 
     return self.name 

    def save(self, *args, **kwargs): 
     self.slug = slugify(self.name) 
     super(Employee, self).save(*args, **kwargs) 

    def get_all_employees(): 
     all_entries = Employee.objects.all().order_by('created') 
     return all_entries 

    def slug(sluggy): 
     sluggy = sluggy.replace(' ', '-').lower() 
     return slugify(sluggy)

あなたはそれで試してみてください：

def user_directory_path(instance, filename): 
# file will be uploaded to MEDIA_ROOT/user_<id>/<filename> 
return 'user_{0}/{1}'.format(instance.user.id, filename) 

class MyModel(models.Model): 
upload = models.FileField(upload_to=user_directory_path)
