使用MongoEngine - Python Flask从主文档中按字符串过滤嵌入文档

from flask import Flask, request
from mongoengine import Document, StringField, EmbeddedDocument, ListField, EmbeddedDocumentField

class EmbeddedDocumentModel(EmbeddedDocument):
    field1 = StringField()
    field2 = StringField()

class MainDocumentModel(Document):
    embedded_documents = ListField(EmbeddedDocumentField(EmbeddedDocumentModel))

app = Flask(__name__)
app.config['MONGODB_SETTINGS'] = {
    'db': 'your_database_name',
    'host': 'your_mongodb_host',
    'port': your_mongodb_port
}

@app.route('/filter', methods=['GET'])
def filter_documents():
    filter_string = request.args.get('filter_string')
    filtered_documents = MainDocumentModel.objects(embedded_documents__field1__icontains=filter_string)
    # 进行其他操作，如返回过滤后的文档列表
