我正在制作食谱网站,因此我有食谱模型,我想要创建这样的形式:
class Recipe(models.Model):
....
products = models.ManyToManyField(ProductMeasurement)
....
我已经有ProductMeasurement模型和表格了:
class ProductMeasurement(models.Model):
product = models.ForeignKey(Product)
measurement = models.ForeignKey(Measurement)
value = models.FloatField()
class FridgeForm(forms.Form):
product = forms.ModelChoiceField(queryset=None, widget=forms.Select(attrs={'class': 'form-control'}))
amount = forms.DecimalField(decimal_places=2, widget=forms.NumberInput(attrs={'class': 'form-control'}))
measurement = forms.ModelChoiceField(queryset=None, widget=forms.Select(attrs={'class': 'form-control'}))
def __init__(self, *args, **kwargs):
super(FridgeForm, self).__init__(*args, **kwargs)
self.fields['product'].queryset = Product.objects.all()
self.fields['measurement'].queryset = Measurement.objects.all()
我想要做的是为食谱模型创建表单。问题是用户想要的配方不会有ProductMeasurements。因此,我需要找到一种方法,以便用户可以在Recipe表单中创建ProductMeasurement。这里有什么可行的方法?
