Question

我有一个模型，我试图在用户提交表单时将用户保存到模型数据库。我有一个网站可以做到这一点，但现在我的编辑说＆＃34;在旧式班上使用超级＆＃34;

我正在使用django 1.8而且我得到了

/ auction / createview / NOT NULL约束中的IntegrityError失败： auction_auction.user_id

这是我能得到的最好的错误。我做过的所有修修补补

 class AuctionCreateView(LoginRequiredMixin,CreateView):
    model = Auction
    action = "created"
    form_class = AuctionForm

    auction_form = AuctionForm(initial={'user':request.user})

class AuctionForm(forms.ModelForm):


class Meta:
    model = Auction
    fields = (
                "user",
                "item_name",
                "reserve",
                "start_date",
                "end_date",

                "description",
                "tags",
        )



 class Auction(models.Model):
        user = models.ForeignKey(User)
        item_id = models.CharField(max_length=255, blank=True, null=True)
        item_name = models.CharField(max_length=255, blank=True, null=True)
        winner = models.ForeignKey(User, related_name='Auction_Winner', blank=True, null=True)
        reserve = MoneyField(max_digits=10, decimal_places=2, default_currency='USD')
        created = models.DateTimeField(editable=False, null=True)

        slug = AutoSlugField(('slug'), max_length=128, unique=True, populate_from=('item_name',))
        start_date = models.DateTimeField(verbose_name="Start date")
        end_date = models.DateTimeField(verbose_name="End date")
        active = models.BooleanField(default=False, verbose_name='Active')
        total_bids = models.IntegerField(default=0, verbose_name='Total bids')
        date_added = models.DateTimeField(auto_now_add=True, verbose_name='Date added')
        last_modified = models.DateTimeField(auto_now=True, verbose_name='Last modified')

        description = models.TextField(max_length=3000)


        tags = tagging.fields.TagField()


    #    bid_set = models.IntegerField(default= 0, verbose_name = "Bid set")
        starting_amount = MoneyField(max_digits=10, decimal_places=2, default_currency='USD')

        def __unicode__(self):
            return '%s selling %s' % (self.user, self.item_name)

        def _get_increment(self):
            """ add some logic to base incrementing amount on starting price """

        def get_absolute_url(self):
            return reverse('auction_detail',
                           kwargs={'slug': self.slug})

当我看到this post时，我以为我能够弄明白。谢谢★✩

Answer 1

You need insert user_id before form save.

AuctionForm - need update request.user value. Added this fields from form initial.

Answer 2

您必须在Auction表单类的字段中包含'user'才能解决该错误，并将一个初始参数放在views.py中的表单实例上，如

auction_form = AuctionForm(initial={'user':request.user})

因为form_valid方法上的request.user无法正常工作

使用django 1.8
