如何根据另一个模型制作模型表单集

发布于 2024-12-04 13:05:58 字数 898 浏览 0 评论 0原文

我目前有两个 Django 模型，一个是设置模型，另一个是该模型的实际数据。像这样：

class Extra(models.Model):
    has_text = models.BooleanField(u'Has Text', default=False)
    has_image = models.BooleanField(u'Has Image', default=False)
    has_file = models.BooleanField(u'Has File', default=False)


class OrderExtra(models.Model):
    extra = models.ForeignKey('Extra')
    image = models.ImageField(upload_to=get_order_extra_upload_path, blank=True, null=True)
    file = models.FileField(upload_to=get_order_extra_upload_path, blank=True, null=True)
    text = models.TextField(blank=True, null=True)
    comments = models.TextField(blank=True, null=True)

我一直在尝试创建一个 OrderExtra 的表单集，该表单集链接到我已过滤掉的 Extra 的查询集。然后隐藏Extra未选中框的字段。

我想为 Extra 制作一个表单并替换创建时的字段，但我不确定如何正确执行此操作...

如果有人可以帮助我，或者提供一些方向太棒了，因为我不知道如何做到这一点......

干杯。

I currently have two Django Models, on it like a setup model and another is the actual data for that model. Like this:

class Extra(models.Model):
    has_text = models.BooleanField(u'Has Text', default=False)
    has_image = models.BooleanField(u'Has Image', default=False)
    has_file = models.BooleanField(u'Has File', default=False)


class OrderExtra(models.Model):
    extra = models.ForeignKey('Extra')
    image = models.ImageField(upload_to=get_order_extra_upload_path, blank=True, null=True)
    file = models.FileField(upload_to=get_order_extra_upload_path, blank=True, null=True)
    text = models.TextField(blank=True, null=True)
    comments = models.TextField(blank=True, null=True)

I've been trying to make a formset of the OrderExtra that is linked up to a queryset of the Extra that I've filtered out. Then hide the fields of the unchecked boxes of the Extra.

I though about making a form for the Extra and replacing the fields on creation, but I wasn't sure how to do this properly...

If anyone could help me, or provide some direction that would be fantastic, because I'm stuck on how to do this...

Cheers.

尝试为 OrderExtra 制作表单，并在其 init 中添加来自相关额外对象的选中字段

class MyForm(forms.ModelForm):
    has_text = None

    class Meta():
        model=OrderExtra

    def __init__(self, *args , **kwargs):
        super(MyForm, self).__init__(*args , **kwargs)
        if self.instance and self.instance.extra.has_text:
            self.has_text = forms.BooleanField(...)

您也可以对 has_image 和 has_file 执行此操作

Try to make form for OrderExtra and in init of it add checked fields from related extra object

class MyForm(forms.ModelForm):
    has_text = None

    class Meta():
        model=OrderExtra

    def __init__(self, *args , **kwargs):
        super(MyForm, self).__init__(*args , **kwargs)
        if self.instance and self.instance.extra.has_text:
            self.has_text = forms.BooleanField(...)

You can do this also for has_image and has_file
