小编Dic*_*mbo的帖子

我有一个 CBV，ListView首先在这里使用我的views.py

class InventoryListView(ListView):
    context_object_name = 'inventorys'
    model = models.Inventory

这里是我的 template_list.html

{% for inventory in inventorys %}
<tr>
  <td>{{ inventory.name }}</td>
  <td>{{ inventory.sn }}</td>
  <td>{{ inventory.employee.name }}</td>
  <td>{{ inventory.desc }}</td>
</tr>
{% endfor %}

它按预期返回所有数据。

但我需要用它添加表单。然后将一些代码添加到我的views.py

class InventoryListView(ListView):
    template_name ='system/inventory_list.html'
    context_object_name = 'inventorys'
    model = models.Inventory

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

    def post(self, request):
        form = InventoryForm(request.POST)

这里是我的 forms.py

class InventoryForm(forms.ModelForm):

    name = forms.CharField(max_length=255)
    sn = forms.DecimalField(max_digits=20, decimal_places=0)
    desc …

发布数据时出错

模型

class Employee(models.Model):
    nik = models.CharField(max_length=100)
    name = models.CharField(max_length=100)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse("system:detail",kwargs={'pk':self.pk})

class EmpLoan(models.Model):
    status = models.BooleanField()
    nominal = models.DecimalField(max_digits=10, …

当我在表单中使用引导模式时，它只显示第一个值。

在这里我的template.html

{% for company in companys %}
<tr>
    <td>{{ company.name }}</td>
    <td>{{ company.desc }}</td>
    <td align="center">
        <button type="button" class="btn btn-warning margin-bottom" data-toggle="modal" data-target="#modal-default2">
            delete
        </button>

        <div class="modal fade" id="modal-default2">
            <div class="modal-dialog">

                <form method="post" action="{% url 'system:company_delete' pk=company.pk %}">
                {% csrf_token %}

                <div class="modal-content">    
                    <div class="modal-body">
                        <input type="text" name="name" maxlength="100" required="" id="id_name" value="{{ company.pk }}">
                        <input type="submit" class="btn btn-primary" value="Delete">
                    </div>
                </div>

                </form>
            </div>
        </div>
    </td>
</tr>

{% endfor %}

它循环所有数据，当点击delete确认表单时会弹出。但它返回相同的值。

但如果没有模态引导它的工作正常。

例子：template.html

{% for company …

出现错误 Django NameError 名称“请求”未定义。

我的 views.py

class ShiftCreateView(CreateView):
    fields = ('name', 'timein', 'timeout', 'desc')
    model = models.Shift

    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.timein = request.POST.get("timein", "")
        self.object.timeout = request.POST.get("timeout", "")
        self.object.save()


        return super(ModelFormMixin, self).form_valid(form)
