Question

我已经为嵌入文档中的字段设置了默认值，但是当我尝试发布数据时，它不接受无值或空值。

以下是我的代码 -

models.py

class MetaData(EmbeddedDocument):
    adcode = StringField(max_length=50, default="", blank=True, Null=True)
    additional_html_below_header = StringField(max_length=50, default="")
    adhoc_plus_disable_pacing = BooleanField(default=False)
    adhoc_plus_has_priority = BooleanField(default=False)
    adhoc_server = StringField(max_length=50, default="")
class LandingPage(Document):
    type = StringField(max_length=50, default="")
    meta_clean_URL_tag = StringField(max_length=50, default="")
    meta_name =  StringField(max_length=50, default="")
    created_time = DateTimeField(default=datetime.datetime.now)
    new = BooleanField(default=False)
    meta_data = EmbeddedDocumentField(MetaData)

serializers.py

class MetaDataSerializer(serializers.EmbeddedDocumentSerializer):
    class Meta:
        model = MetaData

class LandingPageSerializer(serializers.DocumentSerializer):
    meta_data = MetaDataSerializer()
    class Meta:
        model = LandingPage

我在这里做错了吗？

    class MetaDataSerializer(serializers.EmbeddedDocumentSerializer):
        adcode = serializers.CharField(allow_blank=True,allow_null=True)
        adhoc_server = serializes.CharField(allow_blank=True,allow_null=True)
        additional_html_below_header = serializers.CharField(allow_blank=True,allow_null=True)

        class Meta:
            model = MetaData

DRF-mongoengine或者就此而言DRF不允许字符串的空值和空值。需要明确提及它们。强加于模型的边界不在序列化器内部。

上述更改应有助于您按照要求维护验证。

MongoEngine：Embeddeddocument字段没有默认值为none？
