Question

我有2个模板。

-Main layout
   -create_device(template 1)
        -add_device(template 2)
        -add_device(template 2)
        -add_device(template 2)

所以我有create_device布局作为模板，然后是add_device模板。我想要做的是每当用户点击“添加设备”时，我想附加add_device模板。

我的网页如下：

每个白色矩形都是add_device模板。我试着用块但是当我点击“添加设备”时，它每次都会覆盖我的块并且不会追加。它还会删除我的标题：

我尝试在add_device模板

中添加{{block.super}}

create_device:
{% block modbus-device %}
{% endblock %}

add_device:
{% extends "app/create_modbus.html" %}
{% block modbus-device %}

    <div class="panel panel-default"  id="dev_{{ total_forms }}">
        <div class="panel-body">
            .....
        </div>
    </div>

编辑，我需要附加模板的原因是因为每个模板包含1个表单和1个formset，我可以轻松地从我的视图生成，而不是使用jquery来解析和更改id和name属性

形式：

class ModbusRegistersForm(ModelForm):
    ixIOType = ModelChoiceField(queryset=IOType.objects.all())
    ixIOType.widget = Select(attrs={'class': 'form-control', 'data-form': '0'})

    bRange = BooleanField(required=False)
    bRange.widget.attrs['data-form'] = 0

    class Meta:
        model = Register
        fields = ['sRegisterName','iStartingAddr','bRange','ixIOType','iOffset']
        widgets = {
                'sRegisterName': TextInput(attrs={'placeholder': 'Register Name','class': 'form-control', 'data-form': '0'}),
                'iStartingAddr': TextInput(attrs={'placeholder': 'Starting address','class': 'form-control','data-form': '0'}),
                'iOffset': TextInput(attrs={'placeholder': 'Address offset','class': 'form-control','data-form': '0'}),
            }
class CreateModbusForm(ModelForm):
    class Meta:
        model = ModbusDevice
        fields = ['ixModbusDevice', 'sModbusName','iPort', 'iSlave', 'sIP']
        widgets = {
                'sModbusName': TextInput(attrs={'placeholder': 'Device Name','class': 'form-control','data-form': '0',}),
                'iPort': TextInput(attrs={'placeholder': 'Port','class': 'form-control','data-form': '0',}),
                'iSlave': TextInput(attrs={'placeholder': 'Slave id','class': 'form-control','data-form': '0',}),
                'sIP': TextInput(attrs={'placeholder': 'Modbus IP address','class': 'form-control','data-form': '0',})
            }

型号：

class ModbusDevice(models.Model):
    ixModbusDevice = models.AutoField(primary_key=True)
    sModbusName = models.CharField(verbose_name='Device Name',max_length=100)
    iPort = models.IntegerField(verbose_name='Port')
    iSlave = models.IntegerField(verbose_name='Slave ID')
    sIP = models.GenericIPAddressField(verbose_name='IP Address')

    class Meta:
        db_table = 'TModbusDevice'

#Modbus tables
class Register(models.Model):
    ixRegister = models.AutoField(primary_key=True)
    sRegisterName = models.CharField(max_length=100)
    iStartingAddr = models.IntegerField()
    bRange = models.BooleanField(default=False)
    ixIOType = models.ForeignKey(IOType)
    ixModbusDevice = models.ForeignKey(ModbusDevice)
    iOffset = models.IntegerField(blank=True, null=True)

    class Meta:
        db_table = 'TRegister'

视图：

devices = []

modbus_qset = ModbusDevice.objects.all()
if modbus_qset:
    for index, device in enumerate(modbus_qset):
        container = ModbusContainer()
        modbus_form = CreateModbusForm(instance=device, prefix="modbus-id_" + str(device.pk))
        container.modbus_device = modbus_form

        register_qset = Register.objects.filter(ixModbusDevice=device)

        if register_qset:
            InlineFormset = inlineformset_factory(ModbusDevice, Register, ModbusRegistersForm, extra=0)
            register_forms = InlineFormset(instance=device, queryset=register_qset, prefix="register-id_" + str(device.pk))
            container.registers = register_forms
        else:
            InlineFormset = inlineformset_factory(ModbusDevice, Register, ModbusRegistersForm, extra=1)
            register_forms = InlineFormset(prefix="register-id_" + str(device.pk))
            container.registers = register_forms

        total_forms = index+1
        devices.append(container)

在django那里formset，这绝对是你想要的。 formset的作用是动态创建/更改/删除项目列表。因此，您应该检查原始文档：https://docs.djangoproject.com/en/1.8/topics/forms/formsets/，而不是进行模板继承。在这里给你一个具体的例子很难，但谷歌搜索django formset会给你很多。

附加django模板块
