Django 4.2: Why is the QuerySet not filtering correctly with complex conditions?
This might be a silly question, but I'm dealing with I'm stuck trying to I'm working on a Django 4.2 application and I've encountered an scenario with filtering a QuerySet based on complex conditions... I have a model `Product` with fields `name`, `category`, and `price`. I need to filter products that belong to a specific category and have a price greater than a certain value, but the results are not returning as expected. Here’s the code I’m using: ```python from django.db.models import Q # Assuming 'category_id' and 'min_price' are defined elsewhere products = Product.objects.filter(Q(category_id=category_id) & Q(price__gt=min_price)) ``` My expectation is to receive all products from the specified `category_id` that also have a `price` greater than `min_price`. However, when I run the query, it seems to return products from other categories too. I’ve printed both `category_id` and `min_price` just before the query, and they are correct. I’ve also tried breaking the filter into two separate lines, like this: ```python products = Product.objects.filter(category_id=category_id) products = products.filter(price__gt=min_price) ``` But this didn’t yield different results. To help with debugging, I enabled Django's SQL query logging, and this is the generated SQL: ```sql SELECT * FROM product WHERE category_id = %s AND price > %s; ``` The SQL seems correct, but I still receive unexpected results. Could this be related to the way the data is structured in the database or how I’m filtering? Any insights on what could be going wrong would be greatly appreciated! Thanks for your help in advance! This is for a desktop app running on Ubuntu 20.04. Any feedback is welcome! Any ideas what could be causing this? Could this be a known issue? Any pointers in the right direction?
