我有两个型号,都有现场状态'这对他们来说意义不一。
class Order(models.Model):
...
status = models.PositiveIntegerField(default=0, choices=ORDER_STATUSES)
...
class ACS(models.Model):
status = models.IntegerField(default=-1, choices=STATUSES)
order = models.ForeignKey(Order, blank=True, null=True)
...
他们的表格如下:
class ACSForm(forms.ModelForm):
status = forms.ChoiceField(
choices=STATUSES,
widget=forms.Select(attrs={'class': 'form-control'})
)
...
class Meta:
model = ACS
fields = ('status',)
class OrderACSEditForm(forms.ModelForm):
status = forms.ChoiceField(
choices=ORDER_STATUSES,
widget=forms.Select(attrs={'class': 'form-control'})
)
class Meta:
model = Order
fields = ('status',)
我想在同一页面上编辑这两个字段。我的 view.py 看起来像
def edit(request, item_id=""):
data = ACS.objects.get(pk=item_id)
form = ACSForm(instance=data)
order = Order.objects.get(id=data.order.id)
form_edit = OrderACSEditForm(instance=order)
if request.POST:
form = ACSForm(request.POST, instance=data)
form_edit = OrderACSEditForm(request.POST)
if form.is_valid() and form_edit.is_valid():
form_edit.save()
obj = form.save()
messages.add_message(request, messages.SUCCESS, 'Your data successfully saved.')
if request.POST['action'] == "save_stay":
return redirect("/panel/packages/acs/edit/" + str(obj.id))
else:
return redirect("/panel/packages/acs/")
return render(request, 'ui/packages/acs/edit.html', dict(data=data, form=form, form_edit=form_edit, item_id=item_id))
模板:
<div class="form-group {% if form.status.errors %}has-error{% endif %}">
<label>{% trans "Status" %}</label>
{% if form.status.errors %}
{% for error in form.status.errors %}
<label class="control-label">{{ error }}</label>
{% endfor %}
{% endif %}
{{ form.status }}
</div>
<div class="form-group {% if form_edit.status.errors %}has-error{% endif %}">
<label>{% trans "Order status" %}</label>
{% if form_edit.status.errors %}
{% for error in form_edit.status.errors %}
<label class="control-label">{{ error }}</label>
{% endfor %}
{% endif %}
{{ form_edit.status }}
</div>
但是在结果form.status中从form_edit.status获取值不正确。我需要在不更改模型字段名称的情况下解决此问题,但不知道如何。

使用表单的prefix
参数来命名字段名称。
form = ACSForm(prefix='acs', instance=data)
form_edit = OrderACSEditForm(prefix='edit', instance=order)
在使用POST数据实例化表单时,请记住使用相同的前缀。
