Django表格 - 我的图片无效
这太令人讨厌了。我想有使用“的ImageField（）”和Django的内置“从django.contrib.auth.models导入用户”标识用户配置文件，但我的形象总是能” t pass “is_valid（）”。请帮帮我。Django表格 - 我的图片无效
PS。忽略RECAPTCHA位。它与这个bug无关。相信我，相信我。
这是我的views.py
import json
import urllib
import PIL
from django.shortcuts import render, redirect
from django.http import HttpResponse
from django.contrib.auth import authenticate
from django.contrib.auth import login as auth_login
from django.contrib.auth import logout
from django.views.generic import View
from .forms import UserForm, UserProfileForm
from django.conf import settings
def log_out(request):
logout(request)
form = UserProfileForm(request.POST or None)
return redirect("/", request)
def login(request):
if request.method == "POST":
username = request.POST['username']
password = request.POST['password']
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
auth_login(request, user)
return redirect("/", username=request.user.username, is_active=request.user.is_active)
else:
return render(request, 'Index/login.html', {'Error_Message': 'Your account has been disabled'.upper()})
else:
return render(request, 'Index/login.html', {'Error_Message': 'Invalid log in'.upper()})
return render(request, 'Index/login.html', {"username": request.user.username})
def register(request):
Form1 = UserForm(request.POST or None)
Form2 = UserProfileForm(request.POST or None and request.FILES or None)
if request.method == "POST":
recaptcha_response = request.POST.get('g-recaptcha-response')
url = 'https://www.google.com/recaptcha/api/siteverify'
values = {
'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY,
'response': recaptcha_response,
}
data = urllib.parse.urlencode(values).encode()
req = urllib.request.Request(url, data=data)
response = urllib.request.urlopen(req)
result = json.loads(response.read().decode())
if result['success']:
if Form1.is_valid():
User1 = Form1.save(commit=False)
username = Form1.cleaned_data["username"]
email = Form1.cleaned_data["email"]
password = Form1.cleaned_data["password"]
User1.save()
User1 = authenticate(username=username, email=email, password=password)
if User1 is not None:
if User1.is_active:
auth_login(request, User1)
return redirect("/", request)
else:
return render(request, 'Index/login.html', {'Error_Message': 'Your account has been disabled'.upper()})
else:
return render(request, 'Index/register.html', {'Error_Message': 'Invalid sign up'.upper()})
if Form2.is_valid():
User2 = Form2.save(commit=False)
logo = request.FILES["logo"]
user = User1
User2.save()
else:
return render(request, 'Index/register.html', {'Error_Message': 'Invalid logo'.upper()})
else:
return render(request, 'Index/register.html', {'Error_Message': a.upper() for a in result['error-codes']})
return render(request, "Index/register.html", {"is_active": request.user.is_active, "username": request.user.username})
，这是我forms.py
from django import forms
from django.contrib.auth.models import User
from .models import UserProfile
class UserForm(forms.ModelForm):
class Meta:
model = User
fields = ["username", "email", "password"]
class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ["logo"]
我的models.py
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class UserProfile(models.Model):
logo = models.ImageField(upload_to="logos/")
user = models.OneToOneField(User, on_delete=models.CASCADE)
