Question

我正在使用django_select2“ ModelSelect2Widget”并获得html形式的“未找到结果”。怎么了？

models.py

class Department(Catalog):
    name = models.CharField(max_length=50, unique=True)

class Person(Catalog):
    surname = models.CharField(max_length=50)
    name = models.CharField(max_length=50)
    department = models.ForeignKey(Department, on_delete=models.PROTECT)

forms.py

class MyWidget(ModelSelect2Widget):
    model = Department
    search_fields = ['name__icontains', ]


class PersonForm(ModelForm):
    class Meta:
        model = Person
        fields = ['surname', 'name', 'department']
        widgets = {'department': MyWidget}

Answer 1

在表单代码中进行以下更改将在表单PersonForm中工作，并且完全删除字段：

widgets={
            'surname':forms.TextInput(attrs={'class':'form-control'}), 
            'name':forms.TextInput(attrs={'class':'form-control'}),
            'department':MyWidget(attrs={'class':'form-control'}),
        }

完整的PersonForm表单应类似于：

class PersonForm(ModelForm):
    class Meta:
       model = Person
       exclude = () # If you have any column like datetime add that into `exclude`
       widgets={
        'surname':forms.TextInput(attrs={'class':'form-control'}),
        'name':forms.TextInput(attrs={'class':'form-control'}),
        'department':MyWidget(attrs={'class':'form-control'}),
       }

Answer 2

这是我的错误。我已经安装了“ SELECT2”，例如“ django-select2”。我通过删除其链接禁用了“ SELECT2”，但保留了“ django-select2”链接。现在MyWidget可以正常工作。
