Insert data into with pymongo and flask

Question

when i click on submit button i get an error which says:

"TypeError: 'Collection' object is not callable. If you meant to call the 'insert' method on a 'Database' object it is failing because no such method exists."

here is my signin.py code :

from flask import Flask, request, render_template
from pymongo import MongoClient

@app = Flask(__name__)
connection = MongoClient()
db = connection.project #database name.
collection = connection.signup # collection name.

@app.route('/signin/')
def index_show():
     return render_template('signin.html')

@app.route('/signin/', methods = ['POST'])
def signup_form():
   username = request.form['user']
   passowrd = request.form['pass']
   collection.insert({'user': username, 'passoword': passowrd})

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

my html file code is here :

  <!DOCTYPE html>
 <html>
  <head>
    <title></title>
  </head>
  <body>
     <form method="post" action=".">
       <input type="text" name="user" /><br/><br/>
       <input type="password" name="pass" /><br/><br/>
       <input type="submit" name="submit" /><br/><br/>
     </form>
 </body>

The method has been deprecated and is changed to .insert_one() in the pymongo 3.x driver, there is also .insert_many() for multiple document creation:

collection.insert_one({'user': username, 'passoword': passowrd})

The .insert() method is now only supported in the 2.x and lower series.

I don't know why OP getting error but even deprecated .insert() still works in pymongo 3.0.3 which the current version

@user3100115 You're right "deprecated" would be better wording here. The message was intenedd to say "use the new methods" in short.

@NeerajSharma undefined objects are a sure sign of errors. make sure your connections are occuring wthout error. And please make sure the code you are actually using is "scoped" the same was as shown here. Right now collection should be globally scoped and therefore available. You error suggests it is not.

I think, the root cause is in this line:

collection = connection.signup  # collection name.

Contrary to the comment, you're getting a DB named signup. That should rather be:

collection = db.signup

please do make sure that you do this to an existing database,object has been returned successfully. here is my code:

from pymongo import MongoClient

client=MongoClient()
db=client.testdb
new={"shopclues":1234,"rating":3}
result=db.testdb.insert_one(new)   
result.inserted_id
ObjectId('59e2f0f2031b4b0b27ecfa09')
