複数のモデルで注文フォームを作成している場合があります。これらのモデルを1つのフォームにレンダリングしたいのですが、フォームセットが私の答えだと言われました。私はこれがどのように機能するかを研究してきましたが、それでも知らないうちに車輪を回しています。これが単純で、表示されない場合は申し訳ありません。
これが私のモデルです：
class Contact(models.Model):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
email_address = models.EmailField(max_length=275)
address = models.CharField(max_length=10, choices=ADDRESS_CHOICES)
def __unicode__(self):
return "%s %s" % (self.first_name, self.last_name)
class BaseStationary(models.Model):
contact = models.ForeignKey(Contact, related_name='%(class)s_related')
address = models.CharField(max_length=10, choices=ADDRESS_CHOICES)
quantity = models.CharField(max_length=3, choices=QUANTITY_CHOICES)
class Meta:
abstract = True
class LetterHead(BaseStationary):
pass
class WindowEnv(BaseStationary):
pass
class NumberTenEnv(BaseStationary):
pass
class NineByTwelveEnv(BaseStationary):
pass
class TenByThirteenEnv(BaseStationary):
pass
class BusinessCard(models.Model):
contact = models.ForeignKey(Contact, related_name='businesscards')
card_first_name = models.CharField(max_length=100)
card_last_name = models.CharField(max_length=100)
title = models.CharField(max_length=100)
print_choices = models.CharField(max_length=19, choices=PRINT_CHOICES)
card_styles = models.CharField(max_length=12, choices=CARD_CHOICES)
card_email_address = models.EmailField(max_length=275)
office_phone_number = PhoneNumberField(_('main office phone number'),
blank=True, null=True)
toll_free_number = PhoneNumberField(_('toll free number'),
blank=True, null=True)
mobile_number = PhoneNumberField(_('mobile phone number'),
blank=True, null=True)
fax_number = PhoneNumberField(_('main office fax'),
blank=True, null=True)
card_mailing_address = models.CharField(max_length=10,
choices=ADDRESS_CHOICES)
card_quantity = models.CharField(max_length=3,
choices=CARD_QUANTITY_CHOICES)
class RushOrder(models.Model):
contact = models.ForeignKey(Contact, related_name='rushorders')
rush_order = models.BooleanField()
in_hand_date = models.DateField(blank=True, null=True)
class OrderNote(models.Model):
contact = models.ForeignKey(Contact, related_name='ordernotes')
add_note = models.BooleanField()
notes = models.TextField()
これが私のフォームです：
class ContactForm(forms.ModelForm):
address = forms.ChoiceField(required = True, widget=RadioSelect(), choices=ADDRESS_CHOICES)
class Meta:
model = Contact
class LetterHeadForm(forms.ModelForm):
address = forms.ChoiceField(required = True, widget=RadioSelect(attrs={'id': 'letterhead_address', 'required': 'True'}), choices=ADDRESS_CHOICES)
class Meta:
model = LetterHead
widgets = {
'contact': forms.HiddenInput,
'quantity': forms.Select(attrs={'id': 'letterhead_quantity'}, choices=QUANTITY_CHOICES),
}
class WindowEnvForm(forms.ModelForm):
address = forms.ChoiceField(required = True, widget=RadioSelect(attrs={'id': 'windowenv_address', 'required': 'True'}), choices=ADDRESS_CHOICES)
class Meta:
model = WindowEnv
widgets = {
'contact': forms.HiddenInput,
'quantity': forms.Select(attrs={'id': 'windowenv_quantity'}, choices=QUANTITY_CHOICES),
}
class NumberTenEnvForm(forms.ModelForm):
address = forms.ChoiceField(required = True, widget=RadioSelect(attrs={'id': 'numbertenenv_address', 'required': 'True'}), choices=ADDRESS_CHOICES)
class Meta:
model = NumberTenEnv
widgets = {
'contact': forms.HiddenInput,
'quantity': forms.Select(attrs={'id': 'numbertenenv_quantity'}, choices=QUANTITY_CHOICES),
}
class NineByTwelveEnvForm(forms.ModelForm):
address = forms.ChoiceField(required = True, widget=RadioSelect(attrs={'id': 'ninebytwelveenv_address', 'required': 'True'}), choices=ADDRESS_CHOICES)
class Meta:
model = NineByTwelveEnv
widgets = {
'contact': forms.HiddenInput,
'quantity': forms.Select(attrs={'id': 'ninebytwelveenv_quantity'}, choices=QUANTITY_CHOICES),
}
class TenByThirteenEnvForm(forms.ModelForm):
address = forms.ChoiceField(required = True, widget=RadioSelect(attrs={'id': 'tenbythirteenenv_address', 'required': 'True'}), choices=ADDRESS_CHOICES)
class Meta:
model = TenByThirteenEnv
widgets = {
'contact': forms.HiddenInput,
'quantity': forms.Select(attrs={'id': 'tenbythirteenenv_quantity'}, choices=QUANTITY_CHOICES),
}
class BusinessCardForm(forms.ModelForm):
print_choices = forms.ChoiceField(required = True, widget=RadioSelect(), choices=PRINT_CHOICES)
card_styles = forms.ChoiceField(required = True, widget=RadioSelect(), choices=CARD_CHOICES)
card_mailing_address = forms.ChoiceField(required = True, widget=RadioSelect(), choices=ADDRESS_CHOICES)
class Meta:
model = BusinessCard
widgets = {
'contact': forms.HiddenInput,
}
class RushOrderForm(forms.ModelForm):
class Meta:
model = RushOrder
widgets = {
'contact': forms.HiddenInput,
'rush_order': forms.CheckboxInput,
'in_hand_date': forms.extras.SelectDateWidget
}
class OrderNoteForm(forms.ModelForm):
class Meta:
model = OrderNote
widgets = {
'contact': forms.HiddenInput,
'add_note': forms.CheckboxInput,
'notes': forms.Textarea
}
そして、これが私の見解です：
class OrderFormView(CreateView):
model = Contact
form_class = ContactForm
template_name = 'orderform.html'
success_url = 'success'
def get_context_data(self, **kwargs):
context = super(OrderFormView, self).get_context_data(**kwargs)
context.update({
'letterhead_form': LetterHeadForm,
'windowenv_form': WindowEnvForm,
'numbertenenv_form': NumberTenEnvForm,
'ninebytwelveenv_form': NineByTwelveEnvForm,
'tenbythirteenenv_form': TenByThirteenEnvForm,
'businesscard_form': BusinessCardForm,
'rushorder_form': RushOrderForm,
'ordernote_form': OrderNoteForm,
})
return context
def form_valid(self, form):
if form.is_valid():
data = form.cleaned_data
email = OrderFormNotification(to=[settings.ORDERFORM_EMAIL_ADDRESS, ],
extra_context=data)
email.send()
洞察を事前に感謝します。たとえそれがこのためのフォームセットをよりよく理解する方向に私を向けることであっても。
