Django：选择JsonField AS new_name？

Question

I have a table, in which some attributes are columns, and some are implemented as a postgres JsonField.

For the columns, I can write eg

Product.objects.values(brand=F('brand_name'))

for implement a SELECT brand_name AS brand query.

I need to do something similar for a JsonField, eg

Product.objects.values(color=F('jsonproperties__color'))

However, the F expressions do not work correctly with JsonFields, and there doesn't seem to be a fix coming anytime soon.

How could I work around this?

Answer 1

也许一个简单的列表理解就可以满足您的要求：

[{"color": p["jsonproperties"]["color"]} for p in Product.objects.values("color")]
