2nd Screenshot of API API Sample Screenshot
我是Django的新手，我想帮助屏幕截图中的验证有公司名称，位置，标题和user_location字段，除了用户信息和正确的验证 但我想从company_name，location，title和user_location字段中删除验证怎么办？
请找到上面的api截图和
请找到以下脚本，
views.py
class UserRegistrationView(generics.CreateAPIView):
"""
Register a new user.
"""
queryset = User.objects.all()
permission_classes = (permissions.AllowAny, )
def get_serializer_class(self, user_type=None):
if user_type == 'student':
return StudentRegistrationSerializer
return ProfessionalRegistrationSerializer

serializes.py
class ProfessionalRegistrationSerializer(serializers.HyperlinkedModelSerializer):
password = serializers.CharField(max_length=20, write_only=True)
experiences = ExperienceSerializer(required=False)
email = serializers.EmailField()
first_name = serializers.CharField(max_length=30)

class Meta:
model = User

if hasattr(user, 'location'):
user.location.location = user_location
user.save()
else:
UserLocation.objects.create(user=user, location=user_location)

return user
另一个serializes.py for Experiance
class ExperienceSerializer(serializers.HyperlinkedModelSerializer):
user_location = LocationField()
location = LocationField()
class Meta:
model = Experience
fields = ('id', 'company_name', 'company', 'description', 'location',
'title', 'start_date', 'end_date', 'is_current', 'user_location')
我想从company_name，company，description，location，title，start_date，end_date，user_location
中删除验证实际上这些字段是第二页意味着完成第一步后用户移动第二步所以第二步字段是可选的
class ExperienceSerializer(serializers.HyperlinkedModelSerializer):
user_location = LocationField()
location = LocationField()
class Meta:
model = Experience
fields = ('id', 'company_name', 'company', 'description', 'location',
'title', 'start_date', 'end_date', 'is_current', 'user_location')
def create(self, validated_data):
return Experience.objects.create(field_a='value', field_b='value')
在上面的课程中，应该做些什么来删除
的验证"error_msg": {
"location": [
"Expected a dictionary of items but got type \"str\"."
],
"start_date": [
"Date has wrong format. Use one of these formats instead: YYYY[-MM[-DD]]."
],
"end_date": [
"Date has wrong format. Use one of these formats instead: YYYY[-MM[-DD]]."
],
"user_location": [
"Expected a dictionary of items but got type \"str\"."
]
}

答案 0 :(得分：2)
根据快照，您将收到两种类型的验证错误。
如果在模型中根据需要设置了字段，则会发生必填字段错误。您可以在模型中为该字段添加blank=True来更改此设置。
对于第二个错误，您的序列化程序需要一个字典，并且您正在发送一个字符串。您可以通过编写自定义创建方法来删除此验证。

user_location = LocationField()
location = LocationField()
