MongoLab/PyMongo connection error



If I run in the shell:


mongo ds0219xx.mlab.com:219xx/dbname -u user -p pass



It works and allows me to connect to the database and pull information. But if I'm within my python application (Flask) and run this:


import pymongo

client = pymongo.MongoClient("mongodb://user:pass@ds0219xx.mlab.com:219xx/dbname")

db = client["dbname"]

db.users.insert_one(
"user1": "hello"
)



It gives me an:


pymongo.errors.OperationFailure: Authentication failed.



I'm pretty sure it's failing before it gets to the insert_one() call, but I'm not completely sure.



Thanks!

By request, here is the full callback:

Could you include the whole traceback? That way we could be sure if it fails before the insert_one(...) call. Though the error is about auth and that would probably mean during MongClient creation :P

I figured it out. You can do this from the python file and it will work:


connection = pymongo.MongoClient(ab123456.mlab.com, 123456)
db = connection[databasename]
db.authenticate(database_user, database_pass)





Please please please, mark it as correct. This is gem :)

what does this mean? like what are you trying to convey in the first line: pymongo.MongoClient(ab123456.mlab.com, 123456). Does the port number appear as a second argument? or is the password but no username? i'm not sure how to interpret this

I guess ideally phrase that in terms of the URL OP supplied and then it'll make more sense :)

pymongo.errors.ConnectionFailure: timed out





One caveat here. The characters "ab1" are probably referring to the server name, whereas "23456" would be the port, not 123456. So, heads up.

The answer given by @Derek Schuster was correct. Just to make it more clear.


DB_NAME = database_name
DB_HOST = dsxxxxxx.mlab.com
DB_PORT = 12345
DB_USER = user
DB_PASS = pass

connection = MongoClient(DB_HOST, DB_PORT)
db = connection[DB_NAME]
db.authenticate(DB_USER, DB_PASS)



Hope it helps. :)

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right.

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
