我收到上面的错误消息，更具体地说是“ImportError at/ops_page/create”“cannot import name ops_page”。基本上，我有一个名为“ops_page”的应用程序，我似乎无法获得新创建的 url“/ops_page/create”，它应该包含与“ops_page”中的模型对应的表单。我看过类似的线程，并尝试删除 ops_page 应用程序和根目录中的 .pyc 文件，以及删除 sqlite 数据库并重新同步/迁移。知道这里可能有什么问题吗？
我的基本 urls.py:
urlpatterns = patterns('',
.
.
url(r'^ops_page/', include('ops_page.urls')),
.
.
)
我的 ops_page urls.py:
urlpatterns = patterns('',
url(r'^create/$', 'ops_page.views.create'),
)
我的 ops_page models.py:
from django.db import models
from django.conf import settings
import os.path
class OpsPageInfo(models.Model):
campaign_name = models.CharField(max_length=100, unique=True, blank=True)
campaign_pic = models.ImageField(upload_to="images/opspage_pics")
description_header = models.CharField(max_length=100, blank=True)
campaign_description = models.CharField(max_length=600, blank=True)
goal = models.CharField(max_length=100, blank=True)
perk_header1 = models.CharField(max_length=100, blank=True)
perk_description1 = models.CharField(max_length=600, blank=True)
def __unicode__(self):
return self.campaign_name
我的 ops_page views.py:
from django.shortcuts import render_to_response
from ops_page.models import OpsPageInfo
from django.http import HttpResponse
from forms import OpsPageForm
from django.http import HttpResponseRedirect
def create(request):
if request.POST:
form = OpsPageForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/artist_donation/')
else:
form = OpsPageForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('create_opspage.html', args)
我的 ops_page forms.py:
from django import forms
from models import ops_page
class OpsPageForm(forms.ModelForm):
class Meta:
model = ops_page
create_opspage.html 表单:
{% block content %}
<form action="/ops_page/create/" method="post">{% csrf_token %}
<ul>
{{ form.as_ul }}
</ul>
<input type="submit" name="submit" value="Create Ops Page">
</form>
{% endblock %}

我是 django 的新手，所以这可能是我的语法错误或者我没有正确映射。任何帮助将不胜感激。谢谢。
请您参考如下方法:
重要的行:
File "/Users/sethjones/Desktop/atmos_v6/ops_page/forms.py" in <module>
2. from models import ops_page
它告诉您导入不正确。现在，如果您检查 forms.py 文件，您会看到 from models import ops_page 这行确实是错误的。它应该是 from models import OpsPageInfo。
此外，您需要将表单模型属性更改为 model = OpsPageInfo 而不是 model = ops_page
