我用class JsonFormWrapper extends React.Component<PropsT> {
render() {
return (
<React.Fragment>
{this.props.jsonResponse ? (
<Form
schema={this.props.jsonResponse.schema}
uiSchema={this.props.jsonResponse.uiSchema}
/>
) : null}
</React.Fragment>
);
}
}
export default JsonFormWrapper;
和flask-restplus制作了一个简单的Board api系统
下面的代码是我的mongoengine和model
[模型]
serializer[序列化器]
class Article(Document):
no = SequenceField()
subject = StringField(required=True)
content = StringField(required=True)
userid = ReferenceField(User, required=True)
comments = ListField(EmbeddedDocumentField(Comment))
created_at = DateTimeField(default=datetime.datetime.now())
updated_at = DateTimeField(default=datetime.datetime.now())
class User(Document):
no = SequenceField()
userid = StringField(unique=True, required=True)
userpw = StringField(required=True)
created_at = DateTimeField(default=datetime.datetime.now())
class Comment(EmbeddedDocument):
content = StringField(required=True)
userid = ReferenceField(User, required=True)
created_at = DateTimeField(default=datetime.datetime.now())
每篇文章都必须包含from marshmallow import Schema, fields
class UsersSchema(Schema):
class Meta:
fields = ('no', 'userid', 'userpw', 'created_at')
class UserSchema(Schema):
class Meta:
fields = ('no', 'userid', 'userpw', 'created_at')
class ArticleSchema(Schema):
class Meta:
fields = ('no', 'subject', 'content', 'userid', 'comments', 'created_at', 'updated_at')
class ArticleListSchema(Schema):
class Meta:
fields = ('no', 'subject', 'content', 'userid', 'comments', 'created_at', 'updated_at')
模型所引用的用户ID。
因此我将User定义为userid = ReferenceField(User, required=True)模型。
插入数据可以正常工作。但是当我访问列表数据时，它会引发错误。
Article
（当前，mongoengine.errors.DoesNotExist: Trying to dereference unknown document DBRef('user', 'john')已插入{ "_id" : ObjectId("5be136061b48d90b052da22d"), "no" : 18, "subject" : "dasdsadsa", "content" : "userid", "userid" : "john", "comments" : [ ], "created_at" : ISODate("2018-11-06T15:34:33.856Z"), "updated_at" : ISODate("2018-11-06T15:34:33.856Z") }）
插入功能在这里。
article我不知道为什么会发生错误。
这里有解决方案吗？
谢谢。
