Re: Queryset from 2 models with second model filtered.

Typically I simply want to do a left join but have it as an object in django rather than a sql raw query. The queryset would look like. Select a.code as 'product_code', a.description as 'product_description', b.code as 'customer_code', b.code as 'customer_description',

Re: data too long in a CharField column

Hi, I am not sure if truncating the data is a good solution as the user will be under the impression that all the text was saved whereas only the first 255 was really saved. You can add a max_length to your form or modelform field which will block the user from typing more then the max length.
