kandi X-RAY | db.py Summary
db.py is an easier way to interact with your databases. It makes it easier to explore tables, columns, views, etc. It puts the emphasis on user interaction, information display, and providing easy to use helper functions. db.py uses pandas to manage data, so if you're already using pandas, db.py should feel pretty natural. It's also fully compatible with the IPython Notebook, so not only is db.py extremely functional, it's also pretty.

QUESTION
I have a rather simple setup:
...ANSWER
Answered 2022-Mar-11 at 12:48To what I understand, when you are trying to run manually there is no path set as the environment, and when you just do
python file.py
python doesn't know in which environment we are running, which is precisely why, we do sys.path.append, to add the sibling directory path to env.
In the case if you are using an IDE like spyder or pycharm. you have an option to set the directory in which your program is located, or in pycharm it creates the whole program as a package where all the paths are handled by IDE.
QUESTION
I have gone through:
- Error "Previous SQL was not a query" in Python?
- MSSQL2008 - Pyodbc - Previous SQL was not a query
- How to check if a result set is empty?
However none of them have resolved the issue.
The snippet from my db.py file is as follows:
...ANSWER
Answered 2022-Mar-04 at 23:17According to the Python Database API PEP 249 specification, the return value of cursor.execute is not defined. So DB-APIs like pyodbc do not need to define consistent return value.
However, specifically for pyodbc, cursor.execute() returns a object which maintains the description attribute if object contains a value but will be None if an action command:

QUESTION
I'm trying to build an async backend API service using FastAPI, Postgres, and SQLAlchemy Core.
When I was testing my API service without the frontend, it ran perfectly, but as soon as the frontend started to hit the backend many times concurrently, I started seeing the following error:
...ANSWER
Answered 2022-Jan-19 at 01:34I realized that I was assigning DB connection to a global location. This gets into a problem when there are more than 1 request hitting the API server, causing get_async_conn() to be called in a row before the first connection gets released, and the second request replaces the connection that was set up in the Request.db_conn. This was largely due to my stupidity + me trying to find a place that I could access to use the connection without passing the connection object from function to function. Nonetheless, I solved this problem by using encode/databases. Very easy integration, while it lacks details YET. Try this if you are looking for an easy DB connection/session/engine management.

QUESTION
I'm trying to run Python Faust from Docker.
Based on this documentation: https://faust.readthedocs.io/en/latest/userguide/installation.html
I created a simple Docker file:
...ANSWER
Answered 2021-Dec-27 at 23:37Read the error message, where it is clearly stated you are missing a header file:
fatal error: rocksdb/slice.h: No such file or directory 705 | #include "rocksdb/slice.h" | ^~~~~~~~~~~~~~~~~ compilation terminated. error: command '/usr/bin/gcc' failed with exit code 1
Accordingly, you'll need to build and install RocksDB. This is separate from the installation of faust[rocksdb] with pip. That simply installs python-rocksdb, the Python interface to the underlying libraries.
There is even a (third-party) RocksDB docker image based on Python 3.7 Slim.
You could use that directly or take some tricks from the Dockerfile for that image.
QUESTION
I have a docker compose that containss a react app and other django container. They are in the same network so when I try to make curl request from the react container to one of the django services using the service name it works but in the web app it doesn't work and it said :
POST http://backend-account:8000/api/auth/login/ net::ERR_NAME_NOT_RESOLVED
this is my docker compose :
...ANSWER
Answered 2021-Dec-18 at 15:37Your web app (react) is ultimately run in the user's browser and not in the container. At that moment they are not in the same docker network and using the service name won't work like it does when you use curl from within the container.
So you need to expose your service on your server so that the users from its own machine at home using their browser can make the network request.
Then you need to use the server IP address or domain name you have set up, in your frontend code to hit the Django backend.
Since you have already published the ports of your backends, 8080:8000 and 7000:7000, you can hit that service on your server IP if your firewall permits.
For example, use one of those in your frontend code.
