我知道问了类似的问题,但在我的情况下,我在部署到pythonanywhere.com后得到了RelatedObjectDoesNotExist。

" RelatedObjectDoesNotExist:用户没有满足感。"

但是同样的代码在本地机器上工作正常。

Model.py

    from __future__ import unicode_literals

from django.db import models

from django.contrib.auth.models import User
class gwDashboard(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    htmlname = models.CharField(max_length=100)
    def __str__(self):              # __unicode__ on Python 2
        return self.htmlname

class userInformation(models.Model):
    user =  models.ForeignKey(User)
    DbName = models.CharField(max_length=200)
    DbTable = models.CharField(max_length=200)
class Employee(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    department = models.CharField(max_length=100)
class eisfiles(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    htmlname = models.CharField(max_length=100)
    meterId = models.CharField(max_length=100)
    esiid = models.CharField(max_length=100)
    metermultiplier = models.CharField(max_length=100)
    DbName = models.CharField(max_length=100,default='800WILCREST')
    DbTable = models.CharField(max_length=100)

    def __str__(self):
        return self.htmlname
    def __str__(self):
        return self.DbName
class Member(models.Model):
    ID = models.AutoField(primary_key=True)
    FIRST_NAME = models.CharField('First name', max_length=50)
    LAST_NAME = models.CharField('Last name', max_length=50)

# Using multi table inheritance - automaticly creates one to one field
class MemberDetail(Member):
    DATE_OF_BIRTH = models.DateField('Date of birth')
    EMAIL = models.EmailField('E-mail')
    PHONE = models.CharField('Phone', max_length=15)

Views.py

def home(request):
userName = request.user
u = User.objects.get(username=userName);
DbName=u.eisfiles   //THIS LINE OF CODE THROWS ERROR
   try:
    DbName=u.eisfiles   //THIS LINE OF CODE THROWS ERROR
    DbName=u.eisfiles.DbName
    direct=''


    return render_to_response(
    'registration/result.html',
    { 'kWhHeatMap': kWhHeatMap, 'temHeatMap':temHeatMap,"histKwhChart":histKwhChart,'officeBuilding':officeBuilding},
    )
except User.eisfiles.RelatedObjectDoesNotExist:
   pass
   return render_to_response(
   'registration/result.html',
   { 'kWhHeatMap': "", 'temHeatMap':"","histKwhChart":"",'officeBuilding':""},
   )
# except User.AttributeError:
#    return HttpResponse('something went wrong!! try again')
finally:
    pass

您可能想要检查您尝试检索的用户是否确实存在。

userName = request.user # ??? This is the user object not the username
u = User.objects.get(username=userName)

您的查询似乎存在问题。请改为:

user = request.user
u = User.objects.get(id=user.id)
DbName = u.eisfiles.DbName
