更改标签通用内联管理
我在 models.py 中执行以下操作:
class Item(models.Model):
date = models.DateField(_('date'), blank=True, null=True)
description = models.CharField(_('description'), max_length=255)
content_type = models.ForeignKey(ContentType, verbose_name=_('content type'))
object_id = models.PositiveIntegerField(_('object id'), db_index=True)
object = generic.GenericForeignKey('content_type', 'object_id')
class ItemAccountAmountRef(Item):
""" Items of which a Quote or an Invoice exists. """
amount = models.DecimalField(max_digits=10, decimal_places=2)
reference = models.CharField(max_length=200)
debit_account = models.ForeignKey(Account, related_name='receivables_receipt_debit_account')
credit_account = models.ForeignKey(Account, related_name='receivables_receipt_credit_account')
class PaymentItem(ItemAccountAmountRef):
pass
class Payment(models.Model):
invoice = models.ManyToManyField(Invoice, null=True, blank=True)
date = models.DateField('date')
attachments = generic.GenericRelation(Attachment)
site = models.ForeignKey(Site, related_name='payment_site', null=True, blank=True
items = generic.GenericRelation(PaymentItem)
在 admin.py 中:
class PaymentItemInline(generic.GenericTabularInline):
model = PaymentItem
form = PaymentItemForm
class PaymentAdmin(admin.ModelAdmin):
inlines = [PaymentItemInline]
在 forms.py 中:
class PaymentItemForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(PaymentItemForm, self).__init__(*args, **kwargs)
self.fields['credit_account'].label = "Bank Account"
在 PaymentItemInline 中,标签没有更改。我尝试过更改其他属性,例如有效的类。如果我在调试模式下运行 init,我可以看到标签变量正在更改,但是当呈现表单时,该字段仍然标记为信用帐户。有什么建议吗?
I the following in the models.py:
class Item(models.Model):
date = models.DateField(_('date'), blank=True, null=True)
description = models.CharField(_('description'), max_length=255)
content_type = models.ForeignKey(ContentType, verbose_name=_('content type'))
object_id = models.PositiveIntegerField(_('object id'), db_index=True)
object = generic.GenericForeignKey('content_type', 'object_id')
class ItemAccountAmountRef(Item):
""" Items of which a Quote or an Invoice exists. """
amount = models.DecimalField(max_digits=10, decimal_places=2)
reference = models.CharField(max_length=200)
debit_account = models.ForeignKey(Account, related_name='receivables_receipt_debit_account')
credit_account = models.ForeignKey(Account, related_name='receivables_receipt_credit_account')
class PaymentItem(ItemAccountAmountRef):
pass
class Payment(models.Model):
invoice = models.ManyToManyField(Invoice, null=True, blank=True)
date = models.DateField('date')
attachments = generic.GenericRelation(Attachment)
site = models.ForeignKey(Site, related_name='payment_site', null=True, blank=True
items = generic.GenericRelation(PaymentItem)
in the admin.py:
class PaymentItemInline(generic.GenericTabularInline):
model = PaymentItem
form = PaymentItemForm
class PaymentAdmin(admin.ModelAdmin):
inlines = [PaymentItemInline]
in forms.py:
class PaymentItemForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(PaymentItemForm, self).__init__(*args, **kwargs)
self.fields['credit_account'].label = "Bank Account"
In the PaymentItemInline the label is not changing. I have tried changing other attributes e.g. class which work. If I run through the init in debug mode I can see that the label variable is changing however when the form is rendered the field is still labelled credit account. Any suggestions?

你已经成功了 98%。不要尝试在
__init__
中修改表单字段,只需在ModelForm
中重新定义它即可。如果你将它命名为相同的东西,django 将能够弄清楚它应该验证 &保存到ForeignKey
字段。您可以使用相同的公式来完全更改ModelForm
中给定字段的字段或小部件。您可以在此处找到每种模型字段类型的默认表单字段类型: https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#field-types
就是这样。根本不需要重写任何函数:)
顺便说一句,这个字段的文档在这里:https://docs.djangoproject.com/en/dev/ref/forms/fields/#modelchoicefield
You're 98% of the way there. Instead of trying to futz with the form field in
__init__
, just redefine it in yourModelForm
. If you name it the same thing, django will be able to figure out that it is supposed to validate & save to theForeignKey
field. You can use the same formula to change a Field or Widget completely for a given field in aModelForm
.You can find the default form field types for each model field type here: https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#field-types
That's it. No need to override any functions at all : )
Incidentally, the docs for this field are here: https://docs.djangoproject.com/en/dev/ref/forms/fields/#modelchoicefield
