API 端点仅从 mongoDB 返回一条记录

Question

这是我的终点。我不得不删除 objectId，因为它不是 JSON 可序列化的。我怎样才能 return 我的 mongoDB 中的所有记录？

from flask import Flask, jsonify, request
from flask_pymongo import PyMongo
from pymongo import MongoClient
from bson import json_util, ObjectId
import json

app = Flask(__name__)

app.config['MONGO_DBNAME'] = 'dummyDB'
app.config['MONGO_URI'] = 'mongodb://user:pass@ec2-35-153-130-169.compute-1.amazonaws.com:27017/dummyDB?authSource=admin'
client = MongoClient ('mongodb://user:pass@ec2-35-153-130-169.compute-1.amazonaws.com:27017/dummyDB?authSource=admin')
db = client['dummyDB']

mongo = PyMongo(app)
@app.route('/jobdata', methods=['GET'])
def get_all_jobdata():
  jobdata = mongo.db.jobdata

  output2 = []

  for q in jobdata.find():
    output2.append({
    'jobcode' : q['jobcode'],
    'date' : q['date'],
    'mean' : q['mean'],
    'std' : q['std']})

    return jsonify({'result' : output2})

Answer 1

我需要将 return 语句移出 for 循环

for q in jobdata2.find():
    output2.append({
    '_id' : q['_id'],
    'jobcode' : q['jobcode'],
    'date' : q['date'],
    'mean' : q['mean'],
    'std' : q['std']})


  return jsonify({'result' : output2})

python 中的缩进很痛苦

API 端点仅从 mongoDB 返回一条记录

API endpoint only returning one record from mongoDB

python
