Issues with PostgreSQL JSONB Data Integration in a Linux Environment for a New Feature
Does anyone know how to During development of a new feature that involves storing various configuration settings in a PostgreSQL database, I've encountered challenges integrating JSONB data types effectively on our Linux servers. The goal is to allow users to dynamically update settings through a web interface, which then saves these in a JSONB format. I've been setting up a REST API using Flask, which works nicely with PostgreSQL, but I'm running into issues when trying to insert and retrieve JSON data. Here’s a snippet of what I’m using to insert data: ```python import psycopg2 connection = psycopg2.connect( dbname='mydb', user='myuser', password='mypassword', host='localhost' ) cursor = connection.cursor() data = {'setting1': 'value1', 'setting2': 'value2'} query = "INSERT INTO settings (config) VALUES (%s)" cursor.execute(query, [json.dumps(data)]) connection.commit() cursor.close() connection.close() ``` The JSON data seems to insert fine, but retrieving it is where I'm hitting a wall. The retrieval query is also straightforward, but the returned JSON structure doesn’t match what I expected. Here’s what I’m using: ```python cursor.execute("SELECT config FROM settings") results = cursor.fetchall() for result in results: print(result[0]) ``` When I print the results, I see a raw JSON string instead of a dictionary. I want to convert this back to a JSON object automatically. What’s the best practice for handling these JSONB types in Python with PostgreSQL on Linux? Additionally, is there anything specific to the Linux environment that might affect how PostgreSQL handles JSONB data, or any configuration settings I should check? Any advice on best practices for using JSONB in a Flask application running on Linux would be greatly appreciated. I’ve also tried using the `json.loads()` function to convert it manually after retrieval, but that feels like a workaround rather than a solution. Looking for insights on this! Thanks for your help in advance!
