【中文标题】无法将 ModelForm 中的表单属性传递给模板【英文标题】：Can't passe form's attrs in ModelForm to Template 【发布时间】：2021-11-02 05:08:04 【问题描述】：我正在尝试设置一个 ModelForm，但我没有得到我在模板中的表单中设置的属性。 另外，我想以 dd/mm/yyyy 格式获取日期输入， 这是我的模型：
class Delivery(models.Model):
user = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name=_("delivery_user"))
full_name_reciever = models.CharField(_("Reciever Full Name"), max_length=50)
pickup_address = models.ForeignKey(Address, on_delete=models.CASCADE, related_name=_("pickup_address"))
destination_address = models.CharField(max_length=250)
destination_city = models.ForeignKey(City, on_delete=models.CASCADE, related_name=_("delivery_city"))
destination_post_code = models.CharField(max_length=20)
operation_date = models.DateField(
_("desired pickup date"), auto_now=False, auto_now_add=False, blank=False, null=False
)
boxes_number = models.PositiveIntegerField(_("Number of Boxes"), default=1)
boxes_wight = models.PositiveIntegerField(_("Boxes Wight"), default=1)
boxes_volume = models.PositiveIntegerField(_("Boxes Volume"), default=0)
document = models.FileField(
help_text=_("Delivery Documets"),
verbose_name=_("Delivery Certificates"),
upload_to="documents/deliveries_documents/",
)
invoice = models.BooleanField(_("check if you want an invoice"), default=False)
created_at = models.DateTimeField(_("Created at"), auto_now_add=True, editable=False)
updated_at = models.DateTimeField(_("Updated at"), auto_now=True)
delivery_key = models.CharField(max_length=200)
billing_status = models.BooleanField(default=False)
delivery_status = models.BooleanField(default=False)
class Meta:
ordering = ("-created_at",)
verbose_name = _("Delivery")
verbose_name_plural = _("Deliveries")
def __str__(self):
return str(self.created_at)
ModelForm：
class UserDeliveryForm(forms.ModelForm):
class Meta:
model = Delivery
fields = [
"full_name_reciever",
"pickup_address",
"destination_address",
"destination_city",
"destination_post_code",
"operation_date",
"boxes_number",
"boxes_wight",
"boxes_volume",
"document",
"invoice",
"delivery_key",
"billing_status",
"delivery_status",
]
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields["full_name_reciever"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "full name reciever "
)
self.fields["pickup_address"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "pickup address "
)
self.fields["destination_address"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "destination address"
)
self.fields["destination_city"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "destination city"
)
self.fields["destination_post_code"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "Post Code"
)
self.fields["operation_date"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "operation date"
)
self.fields["boxes_number"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "boxes number"
)
self.fields["boxes_wight"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "boxes wight"
)
self.fields["boxes_volume"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "boxes volume"
)
self.fields["document"].widget.attrs.update(
"multiple": True, "class": "form-control mb-2 delivery-form", "Placeholder": "document"
)
self.fields["invoice"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "invoice"
)
self.fields["delivery_key"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "delivery key"
)
self.fields["billing_status"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "billing status"
)
self.fields["delivery_status"].widget.attrs.update(
"class": "form-control mb-2 delivery-form", "Placeholder": "delivery status"
)
还有我的观点：
class DeliveryCreateView(LoginRequiredMixin, UserPassesTestMixin, CreateView):
model = Delivery
fields = [
"full_name_reciever",
"pickup_address",
"destination_address",
"destination_city",
"destination_post_code",
"operation_date",
"boxes_number",
"boxes_wight",
"boxes_volume",
"document",
"invoice",
"delivery_key",
"billing_status",
"delivery_status",
]
template_name = "deliveries/customer/edit_deliveries.html"
success_url = reverse_lazy("account:dashboard")
def test_func(self):
return self.request.user.is_customer and self.request.user.is_active
def post(self, request, *args, **kwargs):
form_class = self.get_form_class()
form = self.get_form(form_class)
files = request.FILES.getlist("decument")
if form.is_valid():
return self.form_valid(form)
else:
return self.form_invalid(form)
def form_valid(self, form):
form.instance.user_id = self.request.user.id
return super().form_valid(form)
我想在我的模板中使用日期格式 dd/mm/yyyy 获取日期纠察线，但是当我手动将输入类型指定为“日期”时我使用日期选择器获得格式 mm/dd/yyyy 的模板。 这是我使用的模板：
% extends "../../account/sub_base.html" %
% load l10n %
% block title %Edit Delivery% endblock %
% block sub_content %
<div class=" col-lg-10 mx-auto">
<h1 class="h3">Create/Edit Delivery</h1>
<div>Add a new <b>Delivery</b> </div>
<hr />
<form name="delivery_form" class="delivery-form" method="post" enctype="multipart/form-data">
% if form.errors %
form.errors
<div class="alert alert-primary" role="alert">
Error: Please try again!
</div>
% endif %
% csrf_token %
<div class="form-group">
<label class="small fw-bold"> form.full_name_reciever.label</label>
form.full_name_reciever
</div>
<div class="form-group">
<label class="small fw-bold"> form.pickup_address.label</label>
form.pickup_address
</div>
<div class="form-group">
<label class="small fw-bold"> form.destination_address.label</label>
form.destination_address </div>
<div class="form-group">
<label class="small fw-bold"> form.destination_city.label</label>
form.destination_city </div>
<div>
<label class="small fw-bold"> form.destination_post_code.label</label>
form.destination_post_code
</div>
% localize on %
<div class="form-group">
<label class="small fw-bold"> form.operation_date.label</label>
form.operation_date
</div>
% endlocalize %
<div>
<label class="small fw-bold"> form.boxes_number.label</label>
form.boxes_number
</div>
<div>
<label class="small fw-bold"> form.boxes_wight.label</label>
form.boxes_wight
</div>
<div>
<label class="small fw-bold"> form.boxes_volume.label</label>
form.boxes_volume
</div>
<div>
<label class="small fw-bold"> form.document.label</label>
<input type="file" multiple value= form.document >
</div>
<div class="form-group form-check">
<label class="small fw-bold"> form.invoice.label</label>
form.invoice
</div>
<div>
<label class="small fw-bold"> form.delivery_key.label</label>
form.delivery_key
</div>
<div class="form-group form-check">
<label class="small fw-bold"> form.delivery_status.label</label>
<input type="checkbox" class="form-check-input" value= form.delivery_status </div>
<button class="btn btn-primary btn-block py-2 mb-4 mt-4 fw-bold w-100" type="button" value="Submit"
onclick="submitForm()">
Add Delivery
</button>
</form>
</div>
<script>
function submitForm()
var form = document.getElementsByName('delivery_form')[0];
form.submit(); // Submit the form
form.reset(); // Reset all form data
return false; // Prevent page refresh
</script>
% endblock %
此外，即使我将表单设置为接受多个文件上传，我也需要在我的模板中手动设置它。还有在表单中的小部件设置中不起作用的 css class='form-control'。
【问题讨论】：
【参考方案1】：您可以在 ModelForm 类中使用流动代码：
operation_date = forms.DateField(widget=forms.DateInput(
attrs="type": 'date', 'required': False, 'value': datetime.datetime.today().strftime('%Y-%d-%m')), label=_("Date"))
【讨论】：
【参考方案2】：我解决了这个问题，我发现我没有将 Mofelform 分配给 Modelview 的上下文数据。 这是 ModelView：
class DeliveryCreateView(LoginRequiredMixin, UserPassesTestMixin, CreateView):
model = Delivery
form_class = UserDeliveryForm
template_name = "deliveries/customer/edit_deliveries.html"
success_url = reverse_lazy("account:dashboard")
def test_func(self):
return self.request.user.is_customer and self.request.user.is_active
def post(self, request, *args, **kwargs):
form_class = self.get_form_class()
form = self.get_form(form_class)
files = request.FILES.getlist("decument")
if form.is_valid():
for f in files:
f.save()
return self.form_valid(form)
else:
return self.form_invalid(form)
def form_valid(self, form):
form.instance.user_id = self.request.user.id
return super().form_valid(form)
这是我得到的结果：
