也许有人可以向我解释一下。
使用以下型号：
class ContactEmail(models.Model):
# Documentation
__doc__ = _(u'Stores an e-mail address for a contact.')
# Enums
CATEGORIES = (
(0, _(u'Personal')),
(1, _(u'Professional')),
)
# Attributes
category = models.IntegerField(choices=CATEGORIES, verbose_name=_(u'category'), help_text=_(u'This values indicates wheter the address is for personal or professional use.'))
email_address = models.EmailField(max_length=255, unique=True, verbose_name=_(u'e-mail address'), help_text=_(u'A valid e-mail address.'))
contact = models.ForeignKey('Contact', related_name=u'emails', verbose_name=_(u'contact'), help_text=_(u'The contact whose the e-mail address is.'))
priority_level = models.PositiveSmallIntegerField(verbose_name=_(u'priority level'), help_text=_(u'An integer used to define a priority level for e-mail addresses of a contact.'))
# Methodes
def __unicode__(self):
return u'%(mail)s' % {u'mail': self.email_address}
# Meta-data
class Meta:
verbose_name = _(u'E-mail')
verbose_name_plural = _(u'E-mails')
unique_together = ('contact', 'priority_level')
class Contact(models.Model):
pass
以下的ModelForms：
class ContactCreateForm(forms.ModelForm):
# Documentation
__doc__ = _(u'A custom form for Contact model.')
# Methods
def __init__(self, *args, **kwargs):
super(ContactCreateForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
if name != 'image':
if field.widget.attrs.has_key('class'):
field.widget.attrs['class'] += ' form-control'
else:
field.widget.attrs.update({'class':'form-control'})
# Meta-data
class Meta:
model = Contact
exclude = ['second_names', 'suffix', 'dob', 'skype_account',]
class ContactEmailCreateForm(forms.ModelForm):
# Documentation
__doc__ = _(u'A custom form for ContactEmail model.')
# Methods
def __init__(self, *args, **kwargs):
super(ContactEmailCreateForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
if field.widget.attrs.has_key('class'):
field.widget.attrs['class'] += ' form-control'
else:
field.widget.attrs.update({'class':'form-control'})
# Meta-data
class Meta:
model = ContactEmail
我正在尝试设置一个包含电子邮件表单集的创建联系表单（意图是使用django-dynamic-formset动态添加表单，就像管理员一样 - 并确保它有效）。以下是观点：
class ContactCreateView(LoginRequiredMixin, CreateView):
template_name = u'frontend/contacts/create.html'
model = Contact
form_class = ContactCreateForm
def get_context_data(self, **kwargs):
context = {
'emails' : inlineformset_factory(parent_model=Contact, model=ContactEmail, form=ContactEmailCreateForm, extra=1),
}
context.update(kwargs)
return super(ContactCreateView, self).get_context_data(**context)
django-dynamic-formset 要求您设置默认情况下在inlineformset_factory中设置的can_delete=True。此参数会为表单集的每种形式添加 DELETE字段。
直到这里，没有什么值得抱怨的。除非它将此字段添加到form.visible_fields，即IMO，这种情况令人不安，因为如果没有form.instance则隐藏此字段：
# create.html
<fieldset class="emails">
<legend>{% trans "E-mail(s)" %}</legend>
{{ emails.management_form }}
{% for form in emails %}
<div class="inline-form-emails">
{{ form.media }}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in form.visible_fields %}
<div class="form-group">
<label for="{{ field.html_name }}" class="col-xs-12 col-sm-5 col-md-3 col-lg-3 control-label">
{{ field.label }} {% if field.field.required %}<span style="color: #a60000;">*</span>{% endif %}
</label>
<div class="col-xs-12 col-sm-7 col-md-9 col-lg-9">
{{ field }}
<span class="help-block">{{ field.help_text }}</span>
</div>
</div>
{% endfor %}
</div>
{% endfor %}
</fieldset>
如您所见：
<fieldset class="emails">
<legend>E-mail(s)</legend>

任何人都有线索？
