Question

我正在尝试从Django的模式形式向DB添加一些数据。填写所有字段并单击提交后，它不会保存在数据库中。这是模型，视图和表单以及模板。我认为问题出在views.py

models.py

class Buyer(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    name = models.CharField(max_length=255)
    phone_numbers = ArrayField(PhoneNumberField())
    industry = models.IntegerField(null=True)
    credit_limit = MoneyField(max_digits=20, decimal_places=2,     
    default_currency='MMK', null=True)
    is_active = models.BooleanField(default=True)
    datetime_created = models.DateTimeField(auto_now_add=True)
    datetime_updated = models.DateTimeField(auto_now=True)

views.py

class BuyerCreateView(AtomicMixin, View):
template_name = 'add_buyer_modal.html'

def get(self, request):
    form = BuyerForm()
    return render(request, self.template_name, {'form': form})

def post(self, request):
    form = BuyerForm(request.POST)
    if form.is_valid():
        form.save()
        messages.success(request, 'Buyer created!', extra_tags='alert alert-success')
        return HttpResponseRedirect(self.request.META.get('HTTP_REFERER'))
    messages.error(request, 'Unable create buyer. {}'.format(form.errors), extra_tags='alert alert-danger')
    return HttpResponseRedirect(self.request.META.get('HTTP_REFERER'))

forms.py

class BuyerForm(forms.ModelForm):
    class Meta:
        model = Buyer
        fields = ['name', 'phone_numbers', 'industry', 'credit_limit']

模板

<div class="modal fade" id="add-buyer-modal" tabindex="-1" role="dialog">
<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <h5 class="modal-title">New Buyer</h5>
            <button type="button" data-dismiss="modal" aria-label="Close" class="close">
                <span aria-hidden="true">&times;</span>
            </button>
        </div>
        <div class="col-md-12 modal-body">
            <form id="buyer-form" method="post" class="submit-form" action="{% url 'buyers:add_buyer' %}">
                {% csrf_token %}
                <div class="col-md-12">
                    <div class="form-group label-floating">
                        <label class="control-label">Name</label>
                        <input autocomplete="false" type="text" name="name" class="form-control" required>
                    </div>
                </div>
                <div class="col-md-12">
                    <div class="form-group label-floating">
                        <label class="control-label">Industry</label>
                        <div class="input-group">
                            <input autocomplete="false" type="number" name="industry" class="form-control" required>
                        </div>
                    </div>
                </div>
                <input id="payment-submit" type="submit" class="btn btn-primary pull-right submit-button" />
            </form>
        </div>
    </div>
</div>

urls.py

urlpatterns = [
url(r'^$', buyers_views.BuyerListView.as_view(), name='buyers_list'),
url(r'^(?P<id>[0-9a-f-]+)/$',
    buyers_views.BuyerDetailView.as_view(), name='buyers_detail'),
url(r'^/buyer/add/', buyers_views.BuyerCreateView.as_view(), name='add_buyer'),

]

检查表格是否无效。您只需填写HTML表单的3个字段中的2个，然后将其发送回服务器。因此，当您检查form.is_valid()时是否可能返回False，因此实际上并没有保存表单。

要进行检查，您可以在if语句中打印出“成功”，然后在if语句中打印出“ failure”之后，放置一条打印语句。如果看不到“成功”字样，则表示您的表格无效。

如果确实是问题所在，请在HTML中为表单中的所有字段添加表单字段。默认情况下，您包含在表单的fields属性中的任何字段都是必需的。这意味着，如果在表单上调用is_valid时未填写该字段，则会抛出该字段的验证错误。
