我使用Python编写了代码,并尝试在网页上显示Mongodb的所有文档。但是,在网页上,我看到列名,但没有数据。 并且在命令上,它确实打印了所有数据。任何帮助将不胜感激。
import pymongo
from pymongo import MongoClient
import datetime
import sys
from flask import Flask, render_template, request
import werkzeug
from flask_table import Table,Col
from bson.json_util import dumps
import json
app = Flask(__name__)
try:
client = pymongo.MongoClient("XXXX")
print("Connected to Avengers MongoClient Successfully from Project
Script!!!")
except:
print("Connection to MongoClient Failed!!!")
db = client.avengers_hack_db
@app.route('/')
def Results():
try:
Project_List_Col = db.ppm_master_db_collection.find()#.limit(10)
for row in Project_List_Col:
print(row)
return render_template('Results.html',tasks=row)
except Exception as e:
return dumps({'error': str(e)})
if __name__ == '__main__':
app.run(debug = True)
HTML(Results.html)页面为:
<html>
<body>
{% for task_id in tasks %}
<h3>{{task_id}}</h3>
{% endfor %}
</body>
</html>
答案 0 :(得分:0)
删除了for循环并重新编写了如下代码:
@app.route('/')
def Results():
try:
Project_List_Col = db.ppm_master_db_collection.find()
return render_template('Results.html',tasks=Project_List_Col)
except Exception as e:
return dumps({'error': str(e)})
if __name__ == '__main__':
app.run(debug = True)
文档按原样显示在HTML页面上。
(***将用于格式化部分。与此同时,任何指针都将不胜感激。)
