QUESTION
I followed this tutorial to deploy a sample application to Heroku. I just added the below method in MyResource
class and returned the result from it instead of "Hello World"
from getIt()
method. I'm connecting to an atlas free tier cluster:
ANSWER
Answered 2019-Feb-09 at 20:48The code I was using to connect to the cluster turned out to be wrong. I followed the directions from the docs and it mentioned this:
To connect to an Atlas M0 (Free Tier) cluster, you must use Java version 8 or greater and use a Java driver version that supports MongoDB 3.4.
So I changed the java version to 1.8

QUESTION
I am basically trying to start an HTTP server which will respond with content from a website which I can crawl using Scrapy. In order to start crawling the website I need to login to it and to do so I need to access a DB with credentials and such. The main issue here is that I need everything to be fully asynchronous and so far I am struggling to find a combination that will make everything work properly without many sloppy implementations.
I already got Klein + Scrapy working but when I get to implementing DB accesses I get all messed up in my head. Is there any way to make PyMongo asynchronous with twisted or something (yes, I have seen TxMongo but the documentation is quite bad and I would like to avoid it. I have also found an implementation with adbapi but I would like something more similar to PyMongo).
Trying to think things through the other way around I'm sure aiohttp has many more options to implement async
db accesses and stuff but then I find myself at an impasse with Scrapy integration.
I have seen things like scrapa, scrapyd and ScrapyRT but those don't really work for me. Are there any other options?
Finally, if nothing works, I'll just use aiohttp and instead of Scrapy I'll do the requests to the websito to scrap manually and use beautifulsoup or something like that to get the info I need from the response. Any advice on how to proceed down that road?
Thanks for your attention, I'm quite a noob in this area so I don't know if I'm making complete sense. Regardless, any help will be appreciated :)

No. pymongo is designed as a synchronous library, and there is no way you can make it asynchronous without basically rewriting it (you could use threads or processes, but that is not what you asked, also you can run into issues with thread-safeness of the code).
Trying to think things through the other way around I'm sure aiohttp has many more options to implement async db accesses and stuff
It doesn't. aiohttp
is a http library - it can do http asynchronously and that is all, it has nothing to help you access databases. You'd have to basically rewrite pymongo on top of it.
Finally, if nothing works, I'll just use aiohttp and instead of scrapy I'll do the requests to the websito to scrap manually and use beautifulsoup or something like that to get the info I need from the response.
That means lots of work for not using scrapy, and it won't help you with the pymongo issue - you still have to rewrite pymongo!
My suggestion is - learn txmongo
! If you can't and want to rewrite it, use twisted.web
to write it instead of aiohttp
since then you can continue using scrapy
!

Install txmongo
You can use txmongo like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
