Hello! Please help me
I want to display in Flask all my data from mongodb by pymongo driver.
After run i see in browser

<pymongo.cursor.Cursor object at 0x7fe1aacc1ed0>

What is it?

my web.py:

from flask import Flask, render_template
from flask.ext.pymongo import PyMongo

app = Flask(__name__)
mongo = PyMongo(app)

@app.route("/")
def home_page():
    name = mongo.db.megoloman_db.myCollections.find()
    return render_template('cities.html', name = name)

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

my html:

<!doctype html>
<title>Hello from Flask</title>

<h1>{{ name }}</h1>

The find() method returns a Cursor instance. You have to iterate that cursor to retrieve the results. You can also do this to get the results as a list:

documents = list(name = mongo.db.megoloman_db.myCollections.find())

Note however, that depending on the size if the collection that can take a lot of memory.

Sorry, that should have read:

documents = list(mongo.db.megoloman_db.myCollections.find())

Do you have any documents in the collection you are querying?

I found that i should fix the data in the MongoDB console by iterating through the collection and the array and converting each element to an

ObjectId.
How can I do this?
