Question

我有几张扬戈模式供我扩大用户使用。问题在于,在使用辛迪布时,该法典不会形成表格(简言之,没有发生任何情况)。没有验证错误。为什么发生这种情况? (这些模型在其他地方造成进口错误)

#!/usr/bin/env python
# encoding: utf-8
from django.db import models
from django.contrib.auth.models import User
from registration.signals import user_registered
from forms import ExtendedRegistrationForm
import hashlib

class InheritedProfile(models.Model):
    first_name = models.CharField("Name", max_length=50, blank=True, null=True)
    last_name = models.CharField("Last name", max_length=50, blank=True, null=True)
    pid = models.CharField("PESEL", max_length=11, blank=True, null=True)
    street = models.CharField("Street", max_length=50, blank=True, null=True)
    number = models.CharField("Flat/house number", max_length=10, blank=True, null=True)
    code = models.CharField("Zip ", max_length=6, blank=True, null=True)
    city = models.CharField("City", max_length=50, blank=True, null=True) 
    class Meta:
        abstract=True

class UserProfile(InheritedProfile):
    def upload_path(self, field_attname):
        filename = hashlib.md5(field_attname).hexdigest()[:4] + "_" + field_attname
        return "uploads/users/%s" % (filename,)

    user = models.ForeignKey(User, unique=True, related_name= profile )
    image = models.ImageField(upload_to=upload_path, verbose_name="Image", blank=True, null=True)

    class Meta:
        ordering = [ -id ]
        db_table =  userprofile 

    def __unicode__(self):
        return u"%s " % self.user.username

def user_created(sender, user, request, **kwargs):
    form = ExtendedRegistrationForm(request.POST)
    extended_user = UserProfile(user=user)
    extended_user.is_active = False
    extended_user.first_name = form.cleaned_data[ first_name ]
    extended_user.last_name = form.cleaned_data[ last_name ]
    extended_user.pid = form.cleaned_data[ pid ]
    extended_user.image = form.cleaned_data[ image ]
    extended_user.street = form.cleaned_data[ street ]
    extended_user.number = form.cleaned_data[ number ]
    extended_user.code = form.cleaned_data[ code ]
    extended_user.city = form.cleaned_data[ city ]
    extended_user.save()

user_registered.connect(user_created)

class Friend(InheritedProfile):
    friend_of = models.ForeignKey(UserProfile, related_name= friend_of )
    class Meta:
        db_table =  friend

与此相反,本法典编制表格不成问题:

#!/usr/bin/env python
# encoding: utf-8
from django.db import models
from django.contrib.auth.models import User
import hashlib

class InheritedProfile(models.Model):
    first_name = models.CharField("Name", max_length=50, blank=True, null=True)
    last_name = models.CharField("Last name", max_length=50, blank=True, null=True)
    pid = models.CharField("PESEL", max_length=11, blank=True, null=True)
    street = models.CharField("Street", max_length=50, blank=True, null=True)
    number = models.CharField("Flat/house number", max_length=10, blank=True, null=True)
    code = models.CharField("Zip ", max_length=6, blank=True, null=True)
    city = models.CharField("City", max_length=50, blank=True, null=True) 
    class Meta:
        abstract=True

class UserProfile(InheritedProfile):
    def upload_path(self, field_attname):
        filename = hashlib.md5(field_attname).hexdigest()[:4] + "_" + field_attname
        return "uploads/users/%s" % (filename,)

    user = models.ForeignKey(User, unique=True, related_name= profile )
    image = models.ImageField(upload_to=upload_path, verbose_name="Image", blank=True, null=True)

    class Meta:
        ordering = [ -id ]
        db_table =  userprofile 

    def __unicode__(self):
        return u"%s " % self.user.username

class Friend(InheritedProfile):
    friend_of = models.ForeignKey(UserProfile, related_name= friend_of )
    class Meta:
        db_table =  friend

我是否应当把这一用户重新定位在其他地方? 信号灯塔造成问题......

您似乎有某种类型的交叉进口;如果您进口一些模型到<代码>forms,并从中进口某种形式到models,这便可能无法解决,因为在处理<代码>models时,需要进口forms;forms要求>models。 ...... 这不能解决!

除此以外,我认为它设计得更好,不需要在模型模块中进口表格,因为它们与看法更相关!
