Django 4.2: How to Correctly Use Raw SQL Queries with ORM in a Custom Model Manager
Can someone help me understand I've been researching this but I'm dealing with I've encountered a strange issue with Could someone explain I'm working on a personal project and After trying multiple solutions online, I still can't figure this out..... I'm currently working on a Django 4.2 application and I need to perform some complex SQL queries that aren't easily achievable with the ORM methods. I've created a custom model manager to encapsulate this logic, but I'm running into issues with how to properly execute raw SQL queries using Django's `raw()` method. Here's what I have: ```python from django.db import models class MyModelManager(models.Manager): def custom_query(self): sql = 'SELECT * FROM myapp_mymodel WHERE some_column = %s' return self.raw(sql, ['some_value']) class MyModel(models.Model): some_column = models.CharField(max_length=100) objects = MyModelManager() ``` When I try to call `MyModel.objects.custom_query()`, I receive the following behavior: ``` ValueError: QuerySet 'MyModel' need to use 'raw()' with a custom manager. ``` I've read through the documentation, but I'm not clear on how to structure my manager to correctly support the `raw()` method. I've also thought about using `connection.cursor()` but Iām unsure of how to handle the result set since I want to return model instances. I've tried various approaches but keep hitting a wall with the behavior message. Can someone guide me on how to properly implement this? Is there a specific way to structure my manager or should I be using a different approach to execute raw SQL? Any insights would be greatly appreciated! Is there a better approach? This is for a web app running on Windows 10. Am I approaching this the right way? The project is a web app built with Python. Thanks, I really appreciate it! This is my first time working with Python LTS. I'm developing on Ubuntu 20.04 with Python. Any help would be greatly appreciated!
