Question

我正在研究Django，django-rest项目，因为我已经搜索过这个问题，但我认为我有循环问题，但我不这么认为......

问题的相关部分在这里：

演示/ views.py

from django.shortcuts import render
from rest_auth.models import Upload, UploadForm
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
# Create your views here.
def home(request):
    if request.method=="POST":
        img = UploadForm(request.POST, request.FILES)
        if img.is_valid():
            img.save()
            return HttpResponseRedirect(reverse('imageupload'))
    else:
        img=UploadForm()
    images=Upload.objects.all()
    return render(request,'home.html',{'form':img,'images':images})

rest_auth / models.py

from django.conf import settings
from rest_framework.authtoken.models import Token as DefaultTokenModel
from .utils import import_callable

from django.db import models
from django.forms import ModelForm

class Upload(models.Model):
    pic = models.ImageField("Image", upload_to="images/")
    upload_date=models.DateTimeField(auto_now_add =True)


# FileUpload form class.
class UploadForm(ModelForm):
    class Meta:
        model = Upload

和演示/ urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.views.generic import TemplateView, RedirectView
from django.conf import settings
from django.conf.urls.static import static
from views import home

from rest_framework_swagger.views import get_swagger_view
import os
PROJECT_DIR=os.path.dirname(__file__)

urlpatterns = [
    url(r'^$', TemplateView.as_view(template_name="home.html"), name='home'),
    url(r'^upload/$', views.home, name='imageupload'),
    url(r'^signup/$', TemplateView.as_view(template_name="signup.html"),
        name='signup'),

问题如下：

文件＆＃34; /Desktop/zadnja/django-rest-auth/demo/demo/urls.py"，第6行，在来自views import file＆＃34; /Desktop/zadnja/django-rest-auth/demo/demo/views.py" ;, line 2，在来自rest_auth.models import Upload，UploadForm ImportError：无法导入名称Upload

Answer 1

由于rest_auth/models.py未从demo/views.py

导入任何组件，因此您没有循环导入

我假设rest_auth是您项目中的应用。要导入Upload和UploadForm，您应该使用绝对导入：

from project_name.rest_auth.models import Upload, UploadForm

ImportError：无法导入名称Upload
