如何在同一个模板中使用两个不同的Django表单?
我的forms.py:
My forms.py:
class AlertForm(forms.ModelForm):
class Meta:
model=Alert
fields = ('high','medium', 'user')
widgets = {
'user': forms.HiddenInput()
}
AlertCountFormset = modelformset_factory(Alert,
form = AlertForm)
另一个Django表单类:
Another Django Form class:
class NotifierForm(forms.ModelForm):
high = forms.ChoiceField(choices=NOTIFIER_TYPE)
medium = forms.ChoiceField(choices=NOTIFIER_TYPE)
low = forms.ChoiceField(choices=NOTIFIER_TYPE)
def save(self, commit=True):
alert = super(NotifierForm, self).save(commit=False)
alert.high = self.cleaned_data["high"]
alert.medium = self.cleaned_data["medium"]
alert.low = self.cleaned_data["low"]
alert.save()
return alert
class Meta:
model=Notifier
fields = ('high','medium', 'low', 'user')
widgets = {
'user': forms.HiddenInput()
}
NotifierFormset = modelformset_factory(Notifier,
form = NotifierForm)
字段:
NOTIFIER_TYPE = (
(0, _('E-mail')),
(1, _('Skype')),
(2, _('IRC'))
)
我想在同一个模板中填写这两个表单。所以我选择为两者编写相同的视图:
I want to fill these two forms at the same template. So i choose to write same views for both i.e. :
def profile_setting(request, slug):
if request.method == 'POST':
alert_form = AlertForm(request.POST)
notifier_form = NotifierForm(request.POST)
if alert_form.is_valid() and notifier_form.is_valid():
alert = alert_form.save(commit=False)
notifier = notifier_form.save(commit=False)
alert.user = request.user.username
notifier.user = request.user.username
notifier.save()
alert.save()
return HttpResponseRedirect(reverse('profile_setting', args=[slug]))
extra_context = {
'alert_form': AlertForm(),
'notifier_form': NotifierForm()
}
return direct_to_template(request,'users/user_profile_setting.html',
extra_context)
根据我的template.html:
According to that in my template.html:
{% block content %}
<h3>{% trans "Alerts limit" %}</h3>
<form action="" method="POST">{% csrf_token %}
{{ alert_form.as_p }}
<input type="submit" value="{% trans 'Update' %}" />
</form>
<h3>{% trans "Notifier setting" %}</h3>
<form action="" method="POST">{% csrf_token %}
{{ notifier_form.as_p }}
<input type="submit" value="{% trans 'Update' %}" />
</form>
一切正确,它也将数据保存到数据库。但问题是每当我填写aler_form并点击更新buttone。它还会以相同的值更新另一个表单,反之亦然。例如,如果我选择
Everything is right, It is saving the data to database also. But the problem is whenever i filled the aler_form and click on the update buttone. it also update the another form with the same value or vice versa. For example if i choose
1 2 3 for high , medium and low for alert_Form
然后它还为notify_form保存相同的值。为什么会发生这种情况。这个意见有问题吗?
Then it also save the same value for notify_form. Why is this happening. Is that something wrong with the views?
使用 前缀
参数,以便您的字段名称不会冲突。
Use the prefix
argument so that your field names don't clash.
例如:
alert form = AlertForm(request.POST, prefix='alert')
notifier_form = NotifierForm(request.POST, prefix='notifier')
您需要在未绑定的表单中使用相同的前缀。
You need to use the same prefix in your unbound forms.
extra_context = { 'alert_form': AlertForm(prefix='alert'), notifier_form': NotifierForm(prefix='notifier') }
使用前缀是,您不需要手动重命名字段,如umnik700在他们的答案中建议的。
The advantage of using prefix is that you don't need to manually rename the fields, as umnik700 suggests in their answer.
