Tasty pie multipart post integer field become array - django

Question

I uploading lie with additional fields to DJANGO testy pie and get validation error
If I post file field and char field - char field become from 'test' to '[test]'
If I post also integer field for example 57 it becomes ['57']
I check fron - it's ok
In back request.POST have converted data... Field in model described as small integer field
class SpkPhotoResource(ModelResource):
img = fields.FileField(attribute="filename", null=True, blank=True)
class Meta:
queryset = SpkPhoto.objects.all()
validation = CleanedDataFormValidation(form_class=forms.SpkPhotoForm)
...
def dehydrate_img(self, bundle):
return repr(bundle.obj.filename.name)
def deserialize(self, request, data, format=None):
if format is None:
format = request.META.get('CONTENT_TYPE','application/json')
if format == 'application/x-www-form-urlencoded':
return request.POST
elif format.startswith('multipart'):
data = request.POST.copy()
data.update(request.FILES)
return data
return super(SpkPhotoResource, self).deserialize(request, data, format)
//model:
class SpkPhoto(models.Model):
....
filename = models.ImageField(db_column='FILENAME', max_length=256, upload_to=getFilePath, null=False, blank=False)
site_order = models.SmallIntegerField(db_column='SITE_ORDER', blank=True, null=True)
class Meta:
...
def save(self, *args, **kwargs):
p = str('media/OFFICE/' + str(self.spk_propertyid.office.id))
self.filename.storage = FileSystemStorage(location = p )
if not self.spk_photoid:
self.spk_photoid = get12charid_spk_photoid()
super(SpkPhoto, self).save(*args, **kwargs)
def delete(self, *args, **kwargs):
p = str('media/OFFICE/' + str(self.spk_propertyid.office.id))
self.filename.storage = FileSystemStorage(location = p )
self.filename.delete()
super(SpkPhoto, self).delete(*args, **kwargs)

FormData multipart -Ajax-post- DJANGO-tastie-deserialize data in querydict is as array so just remake returned data from deserialize make it ok
def deserialize(self, request, data, format=None):
if format is None:
format = request.META.get('CONTENT_TYPE','application/json')
if format == 'application/x-www-form-urlencoded':
return request.POST
elif format.startswith('multipart'):
data = request.POST.copy()
data.update(request.FILES)
data2 = {}
for name, value in data.items():
data2[name] = value
return data2
return super(SpkPhotoResource, self).deserialize(request, data, format)
