But this gives me a DoesNotExist-Error when the Person is a Driver. Is there a way to ask the

Django empty field fallback

由 泄露秘密 提交于 2019-12-30 10:06:18
问题 I have a model that holds user address. This model has to have first_name and last_name fields since one would like to set address to a recipient (like his company etc.).

由 江枫思渺然 提交于 2019-12-30 05:26:34
问题 Using Zend Framework, I've created a Model to insert a record into a database. My question is, after $this->insert($data) how can I switch the active table so that I can insert a record into another table?

So I’d have: class Lead extends Model { // shared lead stuff } class RefinanceLead extends Lead { // stuff specific to refinance leads } My
