django 文档建议我可以从模板中识别隐藏/可见字段。我有两个模型，AddressInfo 和 PharmacyInfo。我需要从一个页面为两个表输入数据。我想隐藏 address_id 字段（来自 PharmacyInfo 模型）。我目前有：
{% for form in formset %}
{% if form.non_field_errors %}
<div class="form_errors">
{{ form.non_field_errors }}
</div>
{% endif %}
{% for field in form.visible_fields%}
<div class="field_content">
<label>{{field.label_tag }}</label>
<div class="field">
{% if field.help_text %}
<div class = "help_text">
{{ field.help_text }}
</div>
{% endif %}
{{ field }}
{{ field.errors }}
</div>
</div>
{% endfor %}
{% endfor %}
class PharmForm(ModelForm):
class Meta:
model = PharmInfo
widgets = {
'address_id': forms.HiddenInput()
}
class AddressForm(ModelForm):
class Meta:
model = AddressInfo
class AddressInfo(models.Model):
address_id = models.AutoField(primary_key=True)
address_1 = models.CharField("Address Line 1", max_length = 64)
address_2 = models.CharField("Address Line 2", max_length = 64, blank=True, null=True)
address_3 = models.CharField("Address Line 3", max_length = 64, blank=True, null=True)
address_4 = models.CharField("Address Line 4", max_length = 64, blank=True, null=True)
town_city = models.CharField("Town or City", max_length = 32)
post_code = models.CharField("Post Code", max_length = 8)
phone = models.CharField("Phone Number - numbers 0-9 only",
max_length = 16) #this must be numeric 0-9 only for auto-dial functionality.
email = models.CharField("email address", max_length = 64) #must be valid email
class PharmInfo(models.Model):
pharm_id = models.AutoField(primary_key=True)
pharm_name = models.CharField("Pharamcy Name", max_length = 64)
address_id = models.ForeignKey(AddressInfo, db_column="address_id")
def pharmView (request, id=None):
pharmForm = PharmForm()
addForm = AddressForm()
if request.method == 'POST': #this is a form submission
if id == None: #it's a new record
pharmForm = PharmForm(request.POST)
addForm = AddressForm(request.POST)
if addForm.is_valid(): #add the address_id into the pharmForm.
request.POST = request.POST.copy()
request.POST['address_id'] = addForm.save().pk
pharmForm = PharmForm(request.POST)
if pharmForm.is_valid():
pharm = pharmForm.save()
return render_to_response('thanks.html',
{'form1': pharmForm,
'form2': addForm},
context_instance=RequestContext(request),
)
else: #it's an existing record
pharm = PharmInfo.objects.get(pk=id)
address = pharm.address_id
pharmForm = PharmForm(request.POST, instance = pharm)
addForm = AddressForm(request.POST, instance = address)
if pharmForm.is_valid() and addForm.is_valid():
pharmForm.save()
addForm.save()
return render_to_response('updateThanks.html',
{'form1': pharmForm,
'form2': addForm},
context_instance=RequestContext(request),
)
else:
if id != None: #form bound to a pharmacy record
pharm = PharmInfo.objects.get(pk=id)
address = pharm.address_id
pharmForm = PharmForm(instance = pharm)
addForm = AddressForm(instance = address)
return render_to_response('institutions/pharm.html',
{'form1': pharmForm,
'form2': addForm},
context_instance=RequestContext(request),
)
return render_to_response('institutions/pharm.html',
{'form1': pharmForm,
'form2': addForm},
context_instance = RequestContext(request),
)
此代码隐藏 address_id 字段的输入框，但仍显示标签。我想隐藏整个 div，但 'form.visible_fields' 并没有从输出中排除它。这让我发疯了。谁能告诉我如何以模板可见的方式标记 address_id 字段。
