in my django project i get a 'ModelFormOptions' object has no attribute 'concrete_model' error

问题

I have added a form for my django rest project. However, I keep getting a 'ModelFormOptions' object has no attribute 'concrete_model' error.

In my User class I have added a new field 'password' and I was trying to create a form. and call the serializer upon it.

My Model:

class User(models.Model):
gender = models.CharField(max_length=10, blank=False, choices=GENDER)
first_name = models.CharField(max_length=20, blank=False)
last_name = models.CharField(max_length=20, blank=False)
position = models.CharField(max_length=50, blank=True)
birthday = models.DateField(auto_created=False, blank=False)
email = models.EmailField(max_length=50)
phone = models.CharField(max_length=15, blank=False)
password = models.CharField(max_length=100, default='something')

Form

class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput)

    class Meta:
        model = User
        fields = ('email', 'password')

Serializer

class UserSerializer(serializers.ModelSerializer):
class Meta:
    model = UserForm
    fields = '__all__'

Here is the Error that occures:

AttributeError at /users/ 'ModelFormOptions' object has no attribute 'concrete_model'

回答1:

Your UserSerializer needs to the refer to your model, not the form:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = '__all__'
