Question

所以，我是Django的新手，这已成为一个令人头痛的问题。所以我正在尝试创建一个扩展的用户配置文件和文档。但是，当我尝试通过表单发布条目时，收到以下错误：

异常类型：/ signup / Exception值中的IntegrityError：（1062， “密钥2的重复输入'64'”）

在发生内部服务器错误崩溃时，我注意到创建了具有相关字段（用户名，密码，名字，姓氏）的新用户，并且配置文件条目也是如此。但是，配置文件条目没有输入所有信息，但配置文件与之关联的用户的ID除外。以下是相关代码：

在views.py中：

from django.shortcuts import render_to_response
from django.template import RequestContext
from portalman.models import FnbuserForm, AuthUserForm, Fnbuser
from django.http import HttpResponseRedirect
from django.core.context_processors import csrf
from django.db import IntegrityError
from django.utils.safestring import mark_safe
from django.contrib.auth.models import User

def signup(request):
  viewParam = {}
  errors = None
  profileForm = FnbuserForm()
  userForm = AuthUserForm() 
  if request.method == "POST":
    profileForm = FnbuserForm(request.POST)
    userForm = AuthUserForm(request.POST)
    if userForm.is_valid() and profileForm.is_valid():
      newuser = User.objects.create_user(userForm.cleaned_data['username'], userForm.cleaned_data['email'], userForm.cleaned_data['password'])

      newuser.first_name = userForm.cleaned_data['first_name']  
      newuser.last_name = userForm.cleaned_data['last_name']
      newuser.save()

      newFnbUser = Fnbuser(user = newuser, #other profile elements#)

      newFnbUser.save()
      return HttpResponseRedirect('/thanks/')
    else:
      profileForm = FnbuserForm() # An unbound profile form
      userForm = AuthUserForm() #An unbound user form
  else:
    viewParam = {'profileForm': profileForm, 'userForm' : userForm, 'links' : links}
    viewParam.update(csrf(request))        
  return render_to_response('signup.html', viewParam, context_instance=RequestContext(request))

在portalman / models.py中：

from django.db import models
from django import forms
from django.contrib.auth.models import User, UserManager
from django.db.models.signals import post_save

class Fnbuser(models.Model):
    telephone = models.CharField(max_length=20, blank=True, null=True)
    additionalNotes = models.TextField(help_text=("Feel free to add additional notes or comments here!"), blank=True, 
                      verbose_name="Notes", null=True)
    canCook = models.BooleanField(verbose_name="Can Cook", default=False, blank=True)
    canTransport = models.BooleanField(verbose_name="Can Tranport", default=False, blank=True)
    canServe = models.BooleanField(verbose_name="Can Serve Food", default=False, blank=True)
    canGarden = models.BooleanField(verbose_name="Can Garden", default=False, blank=True)
    canProgram = models.BooleanField(verbose_name="Can Program", default=False, blank=True)
    canDesign = models.BooleanField(verbose_name="Can Design", default=False, blank=True)
    canAlso = models.CharField(verbose_name="Other", max_length=255, blank=True, null=True)
    user = models.ForeignKey(User, unique=True)     

    def __str__(self):
        return self.user.username

    def create_user_profile(sender, instance, created, **kwargs):
        if created:
            Fnbuser.objects.create(user=instance)

    post_save.connect(create_user_profile, sender=User)

    class Meta:
        verbose_name = "Food Not Bombs User"
        verbose_name_plural = "Food Not Bombs Users"

class AuthUserForm(forms.Form):
    username = forms.RegexField(label=("*Username:"), max_length=30, regex=r'^[\w.@+-]+$', 
                                error_messages = {'invalid': ("This value may contain only letters, numbers and @ . + - _ characters."),
                                                  'inUse' : ("This username is already in use, try another.")},
                                help_text = ("Required. 30 characters or fewer. Letters, digits and @ . + - _ only."))
    password = forms.CharField(label=("*Password:"), widget=forms.PasswordInput, 
                                help_text = ("Required. 30 characters or fewer. Letters, digits and @ . + - _ only."), 
                                error_messages = {'invalid': ("This value may contain only letters, numbers and @ . + - _ characters.")})
    email = forms.CharField(label=("E-Mail Address:"), required=False)                            
    first_name = forms.CharField(label=("First Name:"), required=False)
    last_name = forms.CharField(label=("Last Name:"), required=False)

class FnbuserForm(forms.Form):    
    telephone = forms.CharField(label=("Telephone:"), required=False)
    additionalNotes = forms.CharField(label=("Additional Notes about yourself, or general comments."), 
                                      widget = forms.widgets.Textarea(), required=False)
    canCook = forms.BooleanField(label=("Can Help Cook:"), required=False)
    canTransport = forms.BooleanField(label=("Can Help Transport:"), required=False)
    canServe = forms.BooleanField(label=("Can Help Serve Food:"), required=False)
    canGarden = forms.BooleanField(label=("Can Help Garden:"), required=False)
    canProgram = forms.BooleanField(label=("Can Help Program Site:"), help_text=("""If you can help program the site, 
        note what languages you can program in within the "can also help with" box."""), required=False)
    canDesign = forms.BooleanField(label=("Can Help With Design:"), help_text=("""Photography/Video Editing/Web Design/etc.  Note
        what you can do specifically within the "can also help with" box."""), required=False)
    canAlso = forms.CharField(label=("Can Also Help With:"), required=False)

    class Meta:
        model=Fnbuser

有人能说明出了什么问题吗？我将非常感激！

你不能使用：

Fnbuser.objects.create(user=instance)

在使用以下项创建对象后

newFnbUser.save()

这就是为什么在QuerySet（对象）中调用create方法会引发IntegrityError。
