list comprehension that a list of dictionaries

Question

I have a mongo db cusor object that get converted into a list. The list is a list of dictionaries however when I go to access the value I get this error below:

 in <listcomp>
    for e in app.db.entries.find_one({})
TypeError: string indices must be integers

The code is listed here:

import datetime

from flask import Flask, render_template, request

from pymongo import MongoClient

app = Flask(__name__)

client = MongoClient("mongodb+srv://username:password@MicroBlog.0oxexa.mongodb.net/test")

app.db = client.MicroBlog

@app.route("/", methods = ["GET", "POST"])

@app.route("/home", methods = ["GET", "POST"])

def home():
    if request.method == "POST":

        content = request.form["content"]

        formattedDate =datetime.datetime.today().strftime("%Y-%m-%d")

        app.db.entries.insert_one({"content": content, "date": formattedDate})

        mongo_entries_with_date = [
        (
        e["content"],
        e["date"],
        datetime.datetime.strptime(e["date"], "%Y-%m-%d").strftime("%b %d")
        )
        for e in app.db.entries.find_one({})
        ]

        return render_template("home.html", entries = mongo_entries_with_date), 201

return render_template("home.html"), 200

Answer 1

Just do e = app.db.entries.find_one({}) on the line before mongo_entries_with_date and get rid of the square brackets. or put square brackets around app.db.entries.find_one({}).
