我将供应商字段设为选择下拉框,因为我希望它以这种方式运行,但会产生错误: Enter a list of values
我的模特
class Product(models.Model):
name = models.Charfield(max_length=250)
supplier = models.ManytoManyField(Supplier)
我的表格:
class ProductForm(forms.ModelForm):
class Meta:
model = Product
fields = ['name', 'supplier']
widgets = {
'supplier': forms.Select()
}
def clean_supplier(self):
return [self.cleaned_data['supplier']]]
显示错误:输入值列表
答案 0 :(得分:1)
下拉列表不支持多项选择。使用CheckboxSelectMultiple。
class ProductForm(forms.ModelForm):class Meta: model = Product fields = ['name', 'supplier'] widgets = { 'supplier': forms.CheckboxSelectMultiple() }
def clean_supplier(self): return [self.cleaned_data['supplier']]]
