Flask-PyMongo。如何显示从python到html的所有条目？

Question

一个条目包含：标题、link、时间、文本。如何显示从python到html的所有条目？我尝试了很多选项，但找不到正确的语法。最后尝试：

App.py:

from flask import Flask, render_template, jsonify
from flask_pymongo import PyMongo

app = Flask(__name__)

app.config["MONGO_URI"] = "mongodb+srv://..."
mongo = PyMongo(app)


@app.route('/', methods=['GET'])
def index():
    link = mongo.db.archive.find({"link"})
    title = mongo.db.archive.find({"title"})
    text = mongo.db.archive.find({"text"})
    time = mongo.db.archive.find({"time"})

    return render_template('index.html', title=title, link=link, time=time, text=text)

if __name__ == "__main__":
    app.run(debug=True)

HTML

<ul>
    {% for title in titles %}
    <li>
        <label>
            <span>  TITLE:  {{title}}  <br>  HREF:  {{link}}  <br>  DATE:  {{time_date}} <br>  TEXT:  {{text_stat}}  </span>
        </label>
    </li>
    {% endfor %}
</ul>

请考虑我的评论。

You are querying it wrong, the first argument to the find is the filter, second is projection.

我认为你需要这样做：

app.py:

@app.route('/', methods=['GET'])
def index():
    cur = mongo.db.archive.find({}, {'link': 1, 'title': 1, 'text': 1, 'time': 1, '_id': 0})
    return render_template('index.html', cur=list(cur))

index.html

<ul>
    {% for item in cur %}
    <li>
        <label>
            <span>  TITLE:  {{item.title}}  <br>  HREF:  {{item.link}}  <br>  DATE:  {{item.time}} <br>  TEXT:  {{item.text}}  </span>
        </label>
    </li>
    {% endfor %}
</ul>
