Question

我有一个包含3个应用程序的项目，称为项目，标本和测试。这个工作正常，直到我做出改变（我不记得是什么）。在那之后，Django抛出ImportError: No module named models.我无法想象这是什么问题，因为我认为我已经很好地引用和组织了。

这是我的错误：

ImportError at /

No module named models

Request Method:     GET
Request URL:    http://127.0.0.1:8000/
Django Version:     1.5.5
Exception Type:     ImportError
Exception Value:    

No module named models

Exception Location:     /home/david/mysqldb/dev/mysqldb/teams_db/specimens/views.py in <module>, line 11
Python Executable:  /usr/bin/python
Python Version:     2.7.5

这是我的追溯：

/home/david/mysqldb/dev/mysqldb/teams_db/teams_db/urls.py in <module>

        (r'^specimens/', include('specimens.urls')),

▶ Local vars
/usr/local/lib/python2.7/dist-packages/django/conf/urls/__init__.py in include

            urlconf_module = import_module(urlconf_module)

▶ Local vars
/usr/local/lib/python2.7/dist-packages/django/utils/importlib.py in import_module

        __import__(name)

▶ Local vars
/home/david/mysqldb/dev/mysqldb/teams_db/specimens/urls.py in <module>

    from views import new_specimen, list_specimens, info_specimen

▶ Local vars
/home/david/mysqldb/dev/mysqldb/teams_db/specimens/views.py in <module>

    from tests.models import Test

▶ Local vars

在应用程序tests内部，我有类Test，导致错误的类。这是抛出错误的函数（samples.views）：

from django.shortcuts import render
from django.http import HttpResponse, HttpResponseRedirect,\
                        HttpResponseForbidden, HttpResponseBadRequest,\
                        HttpResponseServerError
from django.core.urlresolvers import reverse
from django.template import RequestContext
from django.shortcuts import render_to_response, get_object_or_404
from forms import SearchForm, SpecimenForm
from projects.models import Project, Serie
from models import Specimen 
from tests.models import Test  ## Test importation!!
import simplejson
import json
from django.core import serializers
from django.forms.models import model_to_dict
import datetime


def new_specimen(request, project_id=None, serie_id=None):
    ...

我在test.models中的Test类：

from django.db import models
from projects.models import Project
from specimens.models import Specimen
#from operator.models import Operator
from django.core.validators import RegexValidator

class Test(models.Model):

    ref         = models.CharField(max_length=70, unique=True)
    #name       = models.CharField(max_length=70, null=True, blank=True, default='NULL')
    project     = models.ForeignKey(Project)
    specimen    = models.ForeignKey(Specimen)
    #operator   = models.ForeignKey(Operator)
    notes       = models.TextField(max_length=170, blank=True)
    description = models.TextField(max_length=170, blank=True)
    start_date  = models.DateField(null=True, blank=True)
    finish_date = models.DateField(null=True, blank=True)
    status      = models.CharField(max_length=70, blank=True)

您需要更多信息吗？如有必要，请告诉我。有什么想法吗？可能是名称tests是保留字？

提前致谢!!

它看起来像一个导入循环，但我怀疑你在其他任何地方导入Test模型。不要在视图from models import Specimen中使用相对导入，这可能会导致您的问题。并且不要在tests.py中放置任何模型，它只应用于测试，并且您不需要任何测试模型进行测试。

突然，没有模块命名模型
