Django form.save에 "TypeError : 정수가 필요합니다"

Question

11 개의 필드와 하나의 이미지 업로드 필드가있는 양식이 있습니다. 채우기 및 제출 후, 정수가 필요하다는 TypeError가 주어집니다. imagefield를 제거하면이 오류가 발생하지 않습니다. 이미지 디렉토리를 확인하면 오류가 발생하기 전에 파일이 서버에 저장됩니다.

Forms.py :

class ListingForm(ModelForm): 
    seller_email = forms.EmailField(max_length="", required=True, widget=forms.TextInput(attrs={'placeholder': "jsmith@stevens.edu"})) 
    title = forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"The Cat in the Hat"})) 
    edition = forms.IntegerField(required=True, widget=forms.TextInput(attrs={'placeholder':"5"})) 
    author = forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"Dr. Seuss"})) 
    isbn = forms.CharField(label="ISBN", required=True, widget=forms.TextInput(attrs={'placeholder':"9780717260591"})) 
    price = forms.FloatField(required=True, widget=forms.TextInput(attrs={'type':"number", 'placeholder':"50.00"})) 
    classcode= forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"MA115"})) 
    #description = forms.CharField(widget=forms.TextArea(attrs={'placeholder':"You should buy this because..."})) 
    condition = forms.ChoiceField(required=True, widget=forms.Select(), choices=([(4,"New"), (3,"Good"), (2,"Fair"), (1,"Poor")])) 
    seller_name = forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"John Doe"})) 
    seller_phone = forms.CharField(widget=forms.TextInput(attrs={'placeholder':"(555) 555-1234"})) 

    picture = forms.ImageField(widget=forms.FileInput('accept':"image/*")) 
    #picture = forms.ImageField() 
    uuid = forms.CharField(widget=forms.HiddenInput(), initial=uuid.uuid4()) 
    timeposted = forms.CharField(widget=forms.HiddenInput(), initial=datetime.now()) 
    sale_status = forms.BooleanField(widget=forms.HiddenInput(), initial=True) 



    class Meta: 
     model = Listing 
     fields = ('seller_email', 'title', 'edition', 'author', 'isbn', 'price', 'classcode', 'description', 'condition', 'seller_name', 'seller_phone', 'picture', 'uuid', 'timeposted', 'sale_status')

Settings.py :

FILE_UPLOAD_PERMISSIONS '0760' 

그것은 그것의 주위에 따옴표를하지 말았어야 : 당신의 settings.py 스크립트에서

#just including pertinent settings... 
FILE_UPLOAD_PERMISSIONS '0760' 
FILE_UPLOAD_HANDLERS ('django.core.files.uploadhandler.MemoryFileUploadHandler', 'django.core.files.uploadhandler.TemporaryFileUploadHandler') 
MIDDLEWARE_CLASSES ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware') 
FILE_UPLOAD_MAX_MEMORY_SIZE '2621440'

, 당신은이 라인을 가지고있다. 정수를 예상 할 때 문자열을 두 번째 인수로 사용하여 os.chmod()를 호출하려고합니다. 특히, 8 진 권한 값. 파이썬에서 선행 0이있는 숫자는 자동으로 8 진수 값으로 간주되어 정수로 변환됩니다. 따라서이 줄을 대신 사용하십시오 :

FILE_UPLOAD_PERMISSIONS = 0760 

그런데 왜 당신은 settings.py에서 등호를 사용하지 않습니까?
